The analysis is based on information received from OIE Member Countries and non member countries. I. LIST A DISEASES 1. Foot and mouth disease 1.1. Africa In 1995, North Africa remained free from foot and mouth disease (FMD). In the rest of the African continent, the virus type has been identified in only a small number of infected countries: • In West Africa: Cameroon and Côte d'Ivoire (virus types O and A). • In East Africa: Kenya (virus types O, A and SAT 2) and Uganda (virus type SAT 2). • In Southern Africa: - In Zambia, a single outbreak due to virus type SAT 3 occurred in June 1995, in the south­ west of the country; it was controlled by animal movement restrictions and a vaccination campaign. - In November 1995, impala {JEpyceros melampus melampus) infected with virus SAT 2 were found in the Kruger National Park, in the eastern part of South Africa where foot and mouth disease is enzootic. In Namibia, an outbreak of FMD had occurred in the Caprivi district in 1994. In June 1995, after seven months had elapsed without any cases of the disease in this district, Namibia declared that it considered the disease to be no longer present on its territory. 1.2. Americas The countries of North America, Central America, the West Indies, the Guyanas, Chile, Uruguay, and the regions of Patagonia in Argentina and Urabá in Colombia, remained free from FMD without vaccination. Furthermore, no outbreaks have occurred in the States of Rio Grande do Sul and Santa Catarina in Brazil since January 1994, in Argentina since April 1994 or in Paraguay since September 1994. 1.3. Asia Foot and mouth disease continued to circulate enzootically in South and South-East Asia. In Peninsular Malaysia, the State of Perlis became infected with virus type A in June 1995, whereas the virus strain had not been isolated in the country since 1973. In the same month, FMD virus type Asia 1 spread to the south of Peninsular Malaysia (States of Johore, Malacca and Negeri Sembilan), following the illegal transportation of animals from infected zones situated farther to the north. In the Philippines, the FMD epizootic which appeared on the island of Luzon in 1994 continued in 1995. The disease occurs chiefly in swine. 1.4. Europe In 1995, FMD (virus type O) occurred on two separate occasions in the eastern part of Europe. The first alert came in Turkish Thrace, with an outbreak in a herd of unvaccinated cattle. This is thought to have been caused by the illegal introduction of animals from the Anatolian region of Turkey. The outbreak was declared to have been eradicated in April 1995. The second alert occurred in a pig production unit in the Moscow region of Russia. All the animals in the unit were slaughtered. In each of the above outbreaks, animal movement restrictions and ring vaccination were applied and there were no further cases. In order to control the epizootic which occurred on its territory in 1994, Greece applied stamping out without resorting to vaccination and carried out serological monitoring with slaughter of reactors. In view of the measures applied, and 12 months having elapsed since the last outbreak, Greece declared itself free from foot and mouth disease in October 1995. 1.5. Middle East In April 1995, a strain of FMD virus type A was isolated in the Anatolian part of Turkey, where this type had not been seen since August 1993. In Israel and the Controlled Territories there were only sporadic outbreaks. In Jordan, where FMD is enzootic, the disease occurred unusually in a desert zone, in February 1995. It was expressed through mortality in lambs, with no clinical signs in adult animals. In the Gaza Strip (Territoires autonomes palestiniens), the disease affected non vaccinated calves imported from an FMD free zone in May 1995. Vesicular stomatitis As in previous years, vesicular stomatitis was diagnosed only in the Americas. An episode of the disease, due to New Jersey virus type, began in the United States of America, in the State of New Mexico, in May 1995. The disease spread to Arizona in June, Colorado and Texas in July, Utah in August and Wyoming in October. A total of 367 outbreaks were recorded, of which 9 5 % were in Colorado and New Mexico. The spread of the disease seems to have been assisted by the rapid multiplication of insect vectors (Simulium sp.) along the Rio Grande and the irrigation channels fed by this river, whereas contacts between animals and animal movements seem to have played a negligible epidemiological role. Control measures included a ban on horse events, restrictions on the movement of susceptible species, vector control and serological tests carried out in premises at risk (field investigations covered 1,143 premises), and in some cases vaccination. In South America, Colombia was again the country in which the disease occurred most frequently, with a predominance of the New Jersey serotype. - 10- 3. Swine vesicular disease Only Italy and Portugal reported the presence of swine vesicular disease on their territory in 1995. In Portugal, where the disease was diagnosed for the first time, the only establishment affected was a commercial unit. The disease is thought to have resulted from the introduction of imported animals. In both countries, all the animals on the affected premises were slaughtered and their carcases destroyed. 4. Rinderpest 4.1. Africa In January 1995, Eritrea reported a case of rinderpest in an ox bought in the market at Asmara. The animal had probably been imported. Rinderpest, which had been suspected in Kenya in December 1994, following the death of around 200 buffalo (Syncerus caffer) in the Tsavo National Park, was confirmed. In May 1995, rinderpest was again diagnosed, in a sick kudu (Tragelaphus spp.) found in the same park. The health status of domestic livestock farmed within the area of the National Park was unaffected, thanks to the protection afforded by vaccination. However, in June 1995, 13 herds of cattle were infected by the disease in Turkana district (north-west of the country), following the illegal introduction of cattle from a neighbouring country. 4.2. Middle East Only Oman and the United Arab Emirates reported outbreaks of rinderpest in their territory in 1995. 4.3. South Asia In India, for the last few years, rinderpest has occurred only in four southern States. In 1995 only the States of Karnataka and Tamil Nadu were affected. This favourable situation enabled India to declare part of its territory "provisionally free from rinderpest" in October 1995. Throughout 1995, Pakistan reported the presence of the disease in its northern territories and in the vicinity of Karachi. In Sri Lanka, no outbreaks have been recorded since March 1994. 5. Peste des petits ruminants As in 1994, peste des petits ruminants was reported in countries of West and East Africa, the Middle East and South Asia. In Gabon, the disease was introduced into two provinces (Estuary and Woleu Ntem) by imported animals. Vaccination was applied. 6. Contagious bovine pleuropneumonia 6.1. Africa Contagious bovine pleuropneumonia remains a major animal health problem for many African countries. In Botswana, where the disease had not been observed since 1939, outbreaks were reported from February 1995 onwards in the extreme north-west of the country, following the illegal introduction of cattle from a neighbouring country some eight months before. From February to November 1995, pleuropneumonia progressed towards the south-east, along the river Okavango. In Tanzania, contagious bovine pleuropneumonia spread to the south of the central railway line, posing a serious threat to neighbouring countries to the south. -11 - 6.2. Asia Bangladesh was the only State in Asia to have reported the presence of the disease on its territory during each month. Myanmar, which had not observed any outbreaks of contagious bovine pleuropneumonia since 1987, reported cases in February and July 1995. In Pakistan, where contagious bovine pleuropneumonia had not been observed for at least ten years, the disease was reported in certain months in 1995. 6.3. Europe In Europe, only Portugal reported outbreaks of contagious bovine pleuropneumonia on its territory in 1995 (only 11 outbreaks, compared to 63 in 1994). Italy, which had not observed any outbreaks since 7 September 1993, informed OIE Member Countries on 25 October 1995 that it considered itself to be free from the disease. 7. Lumpy skin disease As in 1994, lumpy skin disease was reported only in Africa. In Guinea, the disease was suspected for the first time in 1994 and confirmed in 1995. 8. Rift Valley fever No epidemiological^ significant events relating to Rift Valley fever were reported to the OIE in 1995. 9. Bluetongue In Israel, the incidence of bluetongue showed a marked reduction in 1995 (only 7 outbreaks, as opposed to 61 the previous year). In Argentina, some animals were found to be carrying bluetongue virus antibodies, without any clinical cases of the disease ever having been observed. The results of a bioclimatic study showed the area with a high risk of insect vectors to be confined to the north-east of the country. In contrast to 1994, no outbreaks were reported in Japan, even though serological tests revealed the presence of the causal virus. 10. Sheep pox and goat pox In North Africa, the number of outbreaks of sheep pox and goat pox recorded in Algeria and Morocco in 1995 fell by more than 5 0 % compared to 1994, whereas in Tunisia the reduction was less marked. From January 1995, the disease was again reported in Pakistan. The last outbreak had been in 1993. In Eastern Europe, Greece, Moldavia and Russia had all reported the recurrence of the disease on their territory in 1994, following many years of freedom from the disease. In 1995, Azerbaijan and Bulgaria were added to this list of countries. In Bulgaria, 34 farms in three different localities in Burgas region were initially infected in August 1995. In October 1995, sheep pox broke out in another farm in the same district, then, in November, an outbreak epidemiologically unrelated to the earlier outbreaks occurred in Khaskovo region. Greece, which had reported a single outbreak in 1994, in November, reported nine outbreaks in October and November 1995, in various parts of the Evros and Thessalonique prefectures. In Russia, in contrast to 1994, sheep pox and goat pox was not restricted to the Caucasus, but was also found in other Russian territories in Europe and Asia. In Qatar, the disease reappeared in February 1995 after an absence of over two years. -12- 11. African horse sickness After four years of intensive control, Morocco was able to inform the other OIE Member Countries in July 1995 that the country fulfilled the conditions laid down in the OIE International Animal Health Code for recovery of its African horse sickness free status. 12. African swine fever 12.1. Africa As in 1994. several outbreaks of the disease resulted from contact between domestic swine and warthogs (Phacochoerus aethiopicus) in the African swine fever control area set up in the Republic of South Africa. Exports of animals and animal products from this control zone, situated in the north of the country, are prohibited. In Mozambique, the disease was reported for the first time in Niassa province (north of the country). It is thought to have resulted from the introduction of pig meat from Zambezia province. In Namibia, where the disease had not been observed since February 1989, one farm was infected in April and another in October 1995. A diagnosis of African swine fever based on clinical signs and post-mortem findings was made in free-range pig farms in Mbale district in Uganda. Lice and ticks were present on the swine but no Ornithodorus moubata were observed. The last suspected case of African swine fever in this area had been in 1992. Farmers were reminded that swine should be enclosed in pens and should not be fed swill. 12.2. Europe The eradication of African swine fever was successfully completed in Spain, with the result that the country was recognised as free from the disease by decision of the European Commission dated 1 December 1995. With a similar decision having been taken in respect of Portugal on 21 December 1994, the disease has thus been totally eradicated from the Iberian Peninsula. Elsewhere in Europe, only the Italian island of Sardinia remains infected. The number of outbreaks rose from 91 in 1994 to 145 in 1995, an increase of nearly 60%. 13. Classical swine fever 13.1. Americas In Cuba, there was a marked decrease in the incidence of classical swine fever in 1995 (18 outbreaks) compared to 1994 (176 outbreaks). In Costa Rica, only 3 districts were infected with the disease in 1995, compared to 95 in 1994. Argentina, Chile and Paraguay each reported only one outbreak of the disease in 1995. 13.2. Europe Between 1994 and 1995, the number of outbreaks of classical swine fever rose sharply in some European countries (FRY [Serbia and Montenegro], Italy, Russia), whereas it fell in other countries (Bulgaria, Germany, Slovakia). In many cases, it was stated that the disease was due to swine being fed unsterilised swill or to the causal virus circulating in the wild boar population. -13- 14. Highly pathogenic avian influenza (fowl plague) In January 1995, fowl plague was diagnosed in Mexico in the States of Puebla and Querétaro, after a considerable rise in morbidity and mortality and a drop in egg production had been observed in several poultry production units. The Mexican government launched a vast surveillance programme to determine the extent of the disease, and implemented measures including quarantine, voluntary slaughter and vaccination in order to control this episode, which came to an end in June 1995. Subsequently, a serological and virological survey carried out throughout the country did not detect the presence of any highly pathogenic or moderately pathogenic virus. In 1995, the poultry production sector in Pakistan suffered losses due to the disease. Sanitary and vaccine measures were applied to control the disease. In Australia, following the appearance of a outbreak of highly pathogenic avian influenza near Brisbane (State of Queensland) at the end of 1994, all the birds present in the outbreak were destroyed and an epidemiological investigation and a vast clinical surveillance campaign were carried out. No further cases having been detected, Australia declared on 28 June 1995 that Queensland had recovered its highly pathogenic avian influenza free status. 15. Newcastle disease 15.1. Africa In Namibia, Newcastle disease principally affected backyard poultry flocks. However, a flock of ostriches and a commercial poultry production unit were also affected. A Newcastle disease epizootic occurred from August to September 1995 in Réunion Island (French island in the Indian Ocean). The epizootic was controlled by stamping out and vaccination. 15.2. Americas In Canada, in the summer of 1995, double-crested cormorants (Phalacrocorax auritus) on the Ottawa river and Lake Ontario (Ontario province) and on Doré Lake (Saskatchewan province) were affected by Newcastle disease. The end of the episode, which occurred well away from any commercial poultry flocks, coincided with the onset of the first frosts, a period when most of these birds have already migrated south. 15.3. Asia In Taipei China, a Newcastle disease episode occurred in relatively large poultry production units where vaccination had not been carried out for a number of years. The affected units were situated in coastal regions of the island of Taiwan visited by migrating wildfowl, the probable source of the disease. All the poultry in the affected premises were destroyed and a vaccination campaign carried out. 15.4. Europe In Azerbaijan, where no outbreaks of Newcastle disease had been reported since March 1991, an industrial poultry unit was affected by the disease in October 1995. The disease is thought to have been introduced into the unit by young imported poultry. Denmark and Sweden, which had been free from Newcastle disease for many years (since 1972 and 1956, respectively), diagnosed the disease on their territory in 1995 (15 outbreaks in Denmark, outside the industrial poultry sector, one outbreak in Sweden, affecting an industrial unit). In Belgium, Germany and the Netherlands, the flocks affected were principally or exclusively small. In Italy, the disease was diagnosed in a wild pigeon and in a small establishment with chickens and guinea fowl. In Switzerland, the disease occurred in a commercial unit, whereas in 1994 it had affected only a few hens in a backyard flock. -14- II. LIST B DISEASES 1. Rabies During the oral vaccination campaigns for foxes carried out in Europe in 1995, vaccinal baits were distributed, principally from the air, over a territory covering some 570,000 k m spread over 13 countries. The results achieved differed from one country to another. 2 Carrying on the trend observed during the previous five years, the incidence of rabies in France fell by 6 0 % in 1995 compared to 1994 (40 cases in 1995, compared to 99 cases in 1994). Switzerland also recorded a considerable reduction in incidence, passing from 225 cases in 1994 to only 23 cases in 1995. Furthermore, there were no cases of animal rabies in June, July, September, October or December, and during the last eight months of the year there were no positive diagnoses of vulpine rabies. Rabies also seems to have regressed in Austria (only 95 cases in 1995, compared to 254 cases in 1994) and in Germany (855 cases in 1995 compared to 1,359 in 1994). In contrast, Belgium moved from 61 cases in 1994 to 213 in 1995, and Luxembourg from 1 to 15 cases during the same period. 2. Scrcwworm (Cochliomyia hominivorax) In October 1995, the Delegate of Cuba informed the OIE of the presence of screwworm {Cochliomyia hominivorax) in all provinces of the country. In spite of its very wide distribution, the infestation did not cause extensive damage, due in particular to the effectiveness of the specific treatment applied and the surveillance system existing in the country. 3. Bovine spongiform encephalopathy In the United Kingdom, the number of cases of bovine spongiform encephalopathy fell from 26,090 in 1994 to 15,710 in 1995, a drop of nearly 40%. France reported three indigenous cases of bovine spongiform encephalopathy. All three occurred in the Côtes-d'Armor department (Brittany region) and involved dairy cows born before the ban on the use of meat and bone meal in bovine rations. In Portugal, 14 cases were diagnosed. The affected animals were between five and nine years old, and nearly two-thirds of them had been born in Portugal. In Switzerland, the incidence of the disease remained virtually unchanged, with 68 cases being reported in 1995 compared to 64 cases in 1994. 4. Brucellosis in sheep and goats (not due to B. ovis) Peninsular Malaysia began a programme to eradicate brucellosis in sheep and goats, which was introduced into its territory in 1994. The programme is based on the detection and slaughter of reactors, with compensation for the owners concerned and without recourse to vaccination. 5. Japanese encephalitis In April 1995, the virus of Japanese encephalitis was isolated in human and animal (porcine and equine) samples collected on Badu Island, 70 km to the north of the Australian mainland. The virus caused the death of two persons in this island community. Japanese encephalitis had not previously been observed in Australia. It would appear that the migration of wildfowl from Asia to the Torres Strait led to the infection of local mosquito populations. Although further laboratory investigations demonstrated that the virus was circulating in other northern islands of Australia, this incident did not have any serious animal health consequences. A follow-up programme was set up in these islands and the north of Queensland and a vaccination programme for the human population was carried out. -15- 6. Venezuelan equine encephalomyelitis A Venezuelan equine encephalomyelitis epizootic began in Venezuela in April 1995, apparently due to young equids having been introduced into States where the disease is enzootic. By the following September it had spread to La Guajira department in Colombia. Numerous human cases were reported, some of which proved fatal, and, in Colombia, 242 equids died of encephalomyelitis. The episode was halted through vaccination of equids and vector control. In 1995, cases were also reported in Honduras and Panama. 7. Viral haemorrhagic disease of rabbits In Australia, during studies carried out on an island off the southern coast on the characteristics of haemorrhagic disease of rabbits and its potential use as a biological control agent for this species, the causal virus, possibly carried by birds or insects, escaped from the experimental area in October 1995 and spread to wild rabbit populations in the State of South Australia. In November 1995, haemorrhagic disease of rabbits was diagnosed in Ireland for the first time. It occurred in a domestic holding of pet rabbits. The disease was also introduced into Benin, probably through the importation of breeding stock. 8. Spring viraemia of carp In the United Kingdom, spring viraemia of carp was diagnosed in 14 coarse fisheries, one ornamental lake and one ornamental fish farm. All supplying and receiving sites associated with the positive sites were visited and sampled. Eradication of the disease was undertaken on one of the sites but was regarded as impractical on the other sites due to their extensive nature. 9. Infectious haematopoietic necrosis Three outbreaks of haematopoietic necrosis were reported in France. Some of the fish in the outbreaks were destroyed and the remainder salvaged for human consumption. 10. Varroasis Varroasis was diagnosed in the French departments of Guadeloupe and Martinique (West Indies). III. OTHER DISEASES 1. Equine morbillivirus In Australia, a farmer who died of meningo-encephalitis in October 1995, was found on post mortem examination to have been infected with equine morbillivirus. In August 1994, he had assisted at his farm in the north of the State of Queensland during the autopsies on two horses. It was not until after the death of the farmer that one of these horses was shown to have been infected with the virus. No epidemiological link was found between this event and the outbreak in Hendra reported in 1994. Furthermore, all the investigations carried out in 1994 or 1995 in the equine population and wildlife of Queensland as well as in pets and production animals in all establishments having been in contact with the affected farms gave negative results. This has led the Australian authorities to conclude that in all probability the disease was not highly contagious. Research into the origin and nature of the virus and the development of a rapid diagnostic test are still in progress. 2. Infectious anaemia of salmon In Norway, an outbreak of infectious anaemia of salmon was reported in a fish farm in November 1995. SECTION 2 WILDLIFE DISEASES WILDLIFE DISEASES* (data as of 1995) I. LIST A DISEASES 1. Rinderpest An outbreak of rinderpest in Tsavo West National Park (Kenya) has been reported. It appears that mainly buffalo (Syncerus caffer) have been affected, and that the disease has spread to most buffalo herds in Tsavo West. Large numbers of buffalo are reported to have died, as well as some eland (Taurotragus oryx) and possibly Coke's hartebeest (Alcelaphus buselaphus). The source of infection is unknown, but is thought to possibly be via illegal cattle movements. Prior to this outbreak, the nearest known endemic focus of rinderpest was thought to be in Karamoja, Uganda, some 700 kilometres away. Concurrent deaths in impala (Aepyceros melampus) were attributed to anthrax, but no cause has been found for the contemporaneous high mortality in zebra (Equus burchelli) in the same area. In mid-1994, there have also been reports of mortality, associated with keratitis, in lesser kudu (Tragelaphus imberbis) on the Tiva River in and adjacent to Tsavo East National Park, Kenya. Rinderpest has subsequently been confirmed to be responsible for this outbreak, by immunohistochemical staining of fixed tissue, at the Hanover Veterinary School, Germany. Lesser kudu, again afflicted with keratitis, have been reported in northern Tanzania at the same time as those in Kenya, but rinderpest has not yet been confirmed in Tanzania. Rinderpest was reported in early 1995 to be affecting wild boar (Sus scrofa), in the marshes of southern Iraq. 2. Peste des petits niminants There have been recent reports of clinical peste des petits ruminants (PPR) affecting northern Pakistan. PPR virus has been identified as the causative agent. If this pathogen reaches the upper Himalayan pastures, the outlook for the wild ibex (Capra (Capra falconeri). Marco Polo's sheep (Ovis amnion poli) and the blue sheep (Pseudois grim. 3. domestic goats in dangerous caprine ibex), the markhor nayaur), could be Hog cholera At least one focus of classical swine fever (hog cholera) is still active at the border of France and Germany in natural populations of wild boars, but is not yet expanding. Extract from the report of the meeting of the OIE Ad hoc Group on wildlife diseases, which was held in Paris from 13 to 15 June 1995. -19- 4. Highly pathogenic avian influenza (fowl plague) In 1993, avian influenza subtypes H5N2 and H7N1 were isolated from emus (Dromaius novaehollandiae) and rheas (Rhea americana) in Texas and North Carolina, United States of America. These isolates were pathogenic to chickens and turkeys. Follow-up antibody testing was done and serological evidence of infection was found in ratites in 13 states. Subsequent isolations from ratites were H4N6 and H10N4 viruses. Findings are reported in the Proceedings of the United States Animal Health Association, 1994. 5. Newcastle disease A major pandemic of Newcastle disease occurred in domestic poultry throughout Southern Africa in 19941995. The velogenic strain involved was predominantly pneumotropic in domestic fowls, but neurotropic in ostriches and exotic bird collections. Deaths in ostriches caused by this disease were reported from South Africa and Zimbabwe. II. LIST B DISEASES Diseases of multiple 1. species Rabies In the United States of America: rabies strain relocations via canid shipments There have been three recent instances where non-endemic strains of rabies virus have been transported with relocated wildlife in the United States of America. In December 1993, an unvaccinated foxhound in Alabama was confirmed to be infected with the coyote/urban dog strain of rabies virus, which in the United States of America had been restricted to Texas. In 1994, 5 non-vaccinated foxhounds were diagnosed as rabid in Florida. Again the virus was identified as the Texas coyote/urban dog strain. The seriousness of finding the coyote/urban dog rabies virus strain in Florida and Alabama is great: circumstantial evidence strongly suggests that the virus was moved by relocating of coyotes (Canis latrans) for hunting purposes. On 4 January 1995, four grey foxes (Urocyon cinereoargenteus) were shipped from an animal dealer in Texas to a private petting zoo in Montana. Shortly after arrival, one of the foxes died and was diagnosed as rabid. The other three foxes were killed, and one of them was also rabies positive. The virus was identified as a strain only known to occur among grey foxes in a few counties in west-central Texas. Subsequent investigation of this case disclosed that the animal dealer had also shipped grey foxes to four other states and two European countries. Follow-up revealed that a rabid grey fox had been exported to the Netherlands. 2. Bovine tuberculosis Of 40 buffalo sampled in the southern region of the Kruger National Park in South Africa, 67.5% were macroscopically or histologically positive for mycobacteriosis. In the Natal central complex game reserves in South Africa, 73 buffalo from 10 herds were sampled. Three herds in the south-western area of the Umfolosi Game Reserve were found to be infected with bovine tuberculosis, one of which had a prevalence rate of 50%. -20- In the United States of America, bovine tuberculosis was confirmed in a wild mule deer (Odocoileus hemionus) in Big Horn County, Montana. The deer was collected during the fall/winter of 1993-1994 as part of a disease survey around a TB-infected game ranch near Hardin, Montana. The survey was conducted after it was determined that the game ranch contained tuberculosis-infected elk (Cervus elaphus canadensis) in 1993. Efforts were being made to eliminate the disease on the farm by test and removal procedures. Additional surveillance in the area disclosed an infected coyote (Canis latrans). In November 1994, a white-tailed deer (Odocoileus virginianus) that was infected with Mycobacterium bovis was killed by a hunter in Alpena County, Michigan. The source of the infection was not determined and surveillance is underway in both wild and domestic animals. 1 According to information provided by the Cattle Diseases staff of Veterinary Services (USDA/APHIS ), 29 Mycobacterium Aovzs-infected captive cervid herds have been identified in 15 States from January 1991 to January 1995. Most of the herds were depopulated by their owners, but four were released from quarantine after testing and six are under quarantine. Lesions suggestive of tuberculosis were found during the examination of 345 wild boar in Liguria, Italy. Lesion prevalence was 15.5%; typing of the Mycobacteria is in progress. 3. Caprine and ovine brucellosis (B. melitensis) In Europe, Brucella abortus biovar 1 was isolated from two adult male chamois (Rupicapra rupicapra) m 1994 and 1995. Animals had blindness (uveitis), arthritis and orchitis. Concurrent infections have been diagnosed in cattle and humans. A serological survey of 123 wild ungulates during the 1994 hunting season revealed two red deer hinds (Cervus elaphus) with suspicious titres. No chamois were seropositive. The seroprevalence for Brucella has increased in wild boar in Belgium and France and has been attributed to an increase in Brucella suis infection. Currently, 4 0 % of reindeer (Rangifer tarandus) are seropositive to brucellosis in Siberia, and 2 % of the animals have clinical signs related to Brucella suis infection. Brucella abortus is a more common infection of domestic reindeer in forested areas in Siberia where there is contact with cattle. 4. Aujeszky's disease and porcine brucellosis In the United States of America, records were obtained from 16,268 wild pigs that had been tested for swine brucellosis. Positive animals were identified in 58 counties in 9 states, and the overall prevalence of infection was 9% (1,465 of 16,268). Wild pigs that were seropositive for Aujeszky's disease were reported from 10 states. Positive animals were found in 98 counties, and the overall prevalence rate was 27.7% (4,293 of 15,494). Recent studies revealed that Aujeszky's disease virus is shed from the genital organs of wild swine and may be transmitted by sexual contact. Diseases of poultry 5. Avian tuberculosis In Kenya, an outbreak of disease in lesser flamingoes (Phoeniconaias minor) resulted in more than 30,000 deaths in six months. The disease appeared to spread along the Rift Valley lakes and was concentrated on the shores of Lake Bogoria in central Kenya. Coincidental was an unseasonal bloom of algae in the lakes. Greater flamingoes (Phoenicopterus ruber), which adopt a slightly different feeding technique, were unaffected. Histopathology revealed lesions compatible with avian tuberculosis. It is thought possible that the algal toxicity overwhelmed the birds which were already debilitated by tuberculosis. United States of America Department of Agriculture / Animal and Plant Health Inspection Service. -21 - 6. Duck virus enteritis Six duck virus enteritis outbreaks occurred in 1994 in the United States of America. The most significant outbreak occurred in central New York on the Finger Lakes. Approximately 1,400 black ducks (Anas rubripes), mallards (Anas platyrhynchos) and a few geese (Branta canadensis) died in the only known duck plague outbreak in wild migratory waterfowl since an outbreak in 1973 in South Dakota. Duck plague also occurred in small numbers of domestic and captive reared waterfowl in Virginia, Pennsylvania, Texas and California in 1994. To date in 1995, two duck plague outbreaks have been confirmed: one in Maryland and one in California. 7. Avian cholera In the United States of America, avian cholera was confirmed from 25 sites in 1994 and the first quarter of 1995. The largest die-off occurred during 1994 on the Chesapeake Bay in Maryland and Virginia and along the northern coast of North Carolina. Mortality exceeded 35,000 birds including over 23 species, primarily oldsquaw (Clangula hyemalis) (70%), bufflehead (Bucephala albeola) and scoters (Melanitta spp). Waterfowl on the Great Salt Lake in Utah began dying of avian cholera in November 1994 just as an avian botulism outbreak was ending. This first reported epizootic of avian cholera on the Great Salt Lake resulted in the loss of an estimated 5,000-10,000 northern shovelers (Anas clypeata) and 4,000 eared grebes (Podiceps spp). Other instances of large mortality caused by avian cholera occurred in the western United States of America, particularly in California. 8. Mycoplasmosis (M. gallisepticum) The house finch Carpodacus mexicanus was introduced into the Eastern United States of America from the Western United States of America and has increased dramatically in number and geographic range. The first reports of a previously unrecognised syndrome in house finches were received in the suburban Washington, D.C., area during February 1994. People reported several house finches with lesions ranging from slightly swollen eyelids with a clear ocular discharge to severe swelling with loss of sight. Since that time, reports of affected birds have been received from all coastal states from New Hampshire to Georgia, as well as from Pennsylvania and West Virginia. Mycoplasma gallisepticum, a bacterium long associated with infectious sinusitis in domestic turkeys and chronic respiratory disease in chickens, was cultured from several affected birds. This organism previously had not been associated with disease in free-flying passerine birds. Since October 1994, information has been assembled, updated, and disseminated regarding house finch conjunctivitis. A field study to investigate the occurrence of M. gallisepticum in house finches was conducted in Maryland and Georgia from November 1994 through March 1995. Gross lesions of conjunctivitis were present in Maryland and Georgia birds. M. gallisepticum was confirmed by culture or PCR in birds from Maryland and Georgia. M. gallisepticum was recovered from some birds without lesions. Seronegative/clinically normal house finches were experimentally inoculated by eye-drop or spray droplets. The inoculum was a finch-derived M. gallisepticum strain that previously had produced severe air sac lesions when experimentally inoculated in chickens and turkeys. Lesions were produced in all finches inoculated by eye-drop and half of the birds in the spray group. M. gallisepticum was recovered from birds in both inoculated groups 34 days post-inoculation. Controls did not develop lesions and remained negative for M. gallisepticum by culture, PCR, and serological testing throughout the study. -22- Diseases of 9. lagomorphs Viral haemorrhagic disease of rabbits Viral haemorrhagic disease of rabbits entered the United Kingdom in 1992, and has been confined primarily to the southern parts of the country in domestic rabbits. This year, a few cases in wild rabbits (Oryctolagus cuniculus) were associated with foci in domestic populations. III. OTHER DISEASES 1. Encephalitis/myocarditis in African elephants The first documented outbreak of encephalitis/myocarditis (EMC) in free ranging African elephant (Loxodonta africana) was diagnosed in the Kruger National Park (South Africa) last year. Of a total of 68 fatal cases which were recorded, 8 3 % of the victims were adult bulls. Many elephants survive this disease, as is evidenced by seropositive clinically normal animals in many herds. Antibody prevalences ranging from 13 to 5 3 % were found in three different regions of the Kruger National Park. Studies of rodents in the Kruger National Park have been conducted for unrelated purposes since 1984, from which a serum bank was available. Analysis of the rodent trapping data and the stored serum demonstrated that: a) A rodent population explosion occurred in 1993/94, indicated by a trapping success rate that increased from an average of 7 % prior to 1993, to a dramatic 54% in 1993 and 5 6 % in 1994. b) All rodent sera collected prior to 1990 were negative for EMC antibodies. In 1993, 8.3% of rodent sera contained EMC antibodies, while in 1994 seropositivity had increased to 25.2%. Mastomys natalensis (multi-mammate mouse) appeared to be the major species involved, making up 9 5 % of the seropositive rodents. There was a striking temporal correlation between the occurrence of the rodent population explosion, the surge in prevalence of antibody to EMC in rodents, and the occurrence of the outbreak of disease in elephants. Subsequently, there has been a dramatic population decline amongst the rodents, and this has been paralleled by an equally dramatic decrease in the incidence of clinical disease in elephants. A killed adjuvanted vaccine against EMC was developed at Onderstepoort Institute for Exotic Diseases, and tested in mice, domestic pigs and elephants. The vaccine was found to elicit high titres of neutralising antibodies, which resulted in a solid protection to challenge with virulent EMC virus. 2. Canine distemper in lions An epidemic of canine distemper was reported in lions (Panthera leo) in the Serengeti and Masai Mara National Parks in Tanzania and Kenya respectively. These two national parks are linked, and this is the first confirmed report of canine distemper in free ranging lions. The report indicates that between 20 and 30% of the 3,000 lions present in this ecosystem have been affected. Symptoms include myoclonus, chorea, ataxia and seizures. Some lions also exhibited ocular and nasal discharge. In some cases, entire prides have died. It is speculated that the Masai's domestic dogs which share the ecosystem were the probable source of infection. 3. Parafilaria in buffalo An ulcerative dermatitis syndrome in buffalo, which was recently researched in the Eastern Transvaal (South Africa) has been found to be caused by a new (yet unnamed) species of Parafilaria. Prevalence rates of between 26 and 5 6 % were encountered in certain buffalo herds. The lesions are highly seasonal (November to February) and occur mainly on the withers, neck and thorax. The lesions begin as focal -23- point haemorrhages seen on the surface of the skin, and expand with time, due to a local hypersensitivity reaction with vasculitis and thrombosis. Lesions are compounded by the attention of oxpeckers (Buphagus spp), to form large ulcerated lesions of up to 30 centimetres in diameter. The lesions heal in the autumn leaving characteristic hairless scars. This parasite is transmitted by flies of the genus Musca. 4. Ulcerative dermatitis in hippopotami In the Kruger National Park (South Africa), button shaped skin ulcerations (2-5 centimetres in diameter) with raised edges were found over the flank areas of hippopotami (Hippopotamus amphibius). These lesions were found to be caused by a filarial parasite of the genus Stephanofilaria, which is related to the parasite that causes the ulcerative skin lesions on the thorax of black rhinos. This parasite appears to be a previously undescribed new species. 5. Infectious "capped elbow" in lions Recently, young lions in several prides in the greater Kruger National Park complex, in Umfolosi game reserve (Natal) and at Kapama (private game reserve) in South Africa were seen to have large fluid-filled swellings over the elbow joints. These swellings are a result of inflammation of the synovial structures in or around the elbow joint. The fact that several lions in each pride were simultaneously affected indicated a possible infectious agent being involved, and an unidentified species of Mycoplasma has subsequently been isolated from fluid aspirated from these swellings. The long term significance of this syndrome is unknown. 6. Infectious polyarthritis in farmed crocodiles A debilitating polyarthritis in farmed crocodiles (Crocodylus niloticus) has been reported from Zimbabwe. Once again an unidentified Mycoplasma, which did not react with the standard conjugates, was isolated from synovial aspirates. 7. Ebola virus in chimpanzees A Swiss ethologist became infected with Ebola virus in November 1994, after carrying out an autopsy on a chimpanzee (Pan troglodytes) in Côte d'Ivoire. The researcher had been investigating a spate of deaths among local chimpanzees. She exhibited classic symptoms of Ebola infection, according to a member of the staff of the Institut Pasteur in Paris, where the virus was identified. The patient has survived and has recovered from the infection. The Pasteur Institute's conclusions are being reviewed by the US Centre for Disease Control and Prevention (CDC) in Atlanta. While the Institut Pasteur and the CDC officials are confident that the virus found in the Côte d'Ivoire is a strain of Ebola, they are unsure of its relationship with the viral types which have caused the recent outbreaks in Sudan and Zaire. As chimpanzees seem to be very susceptible to this Ebola strain, they are unlikely to be the wild reservoir of the virus. 8. Viral blindness in kangaroos In Australia, an infection causing blindness in kangaroo has been apparent for at least eighteen months from western New South Wales (around Broken Hill) down across the Murray River to Bendigo and Ballarat in Victoria, across through South Australia and even on Kangaroo Island, off the coast of South Australia. Reports vary but it seems that between 5 and 30% of a mob of kangaroos can be affected by the disease, which causes complete blindness. Infected animals are easily identified by their tentative, high-stepping gait, but eye lesions are not obvious from a distance. On examination, there is massive chorioretinitis with complete destruction of the retina. In severe cases there are inflammatory lesions down the optic nerve leading to wallerian degeneration and encephalitis. There is no conjunctivitis or hypopyon apparent. -24- The species affected include red kangaroos (Macropus rufas) and euros (M. robustus). Older animals seem to be most commonly affected and death is usually due to trauma (road accidents), emaciation or drowning. It is thought that the disease is insect-borne by either sandflies or mosquitoes, since it appears to be most common in late summer when insects are more numerous. Three laboratories have isolated arboviruses from the retinas of blind kangaroos but all three viruses are different. It is as yet unclear which virus is the causal organism and work continues. 9. Unexplained ostrich mortality The Australian Ostrich Association has announced that an unexplained disease condition has killed thousands of fanned ostrich (Struthio camelus) chicks in New South Wales, Victoria and Queensland. The causal agent has yet to be identified but does not appear to be a virus. Current opinion points towards an aberrant feeding or management practice. At first it was feared that the indigenous emu (Dromanius novaehollandiae) might be at risk but this is now seen to be unlikely. 10. Hantavirus The known range of hantaviruses that cause the hantavirus pulmonary syndrome (HPS) in human beings has expanded in the United States of America. As of 15 March 1995, there were 195 human cases of infection with a mortality rate of 52%. The majority of the cases occurred west of the Mississippi River, where the deer mouse, Peromyscus maniculatus, is the primary reservoir, and the virus involved is called Sin Nombre virus. Cases have been found outside the range of P. maniculatus in eastern Texas, Louisiana, Florida, and Rhode Island. In Florida, another hantavirus, Black Creek Canal Virus, has been isolated from the cotton rat, Sigmodon hispidus. The Louisiana case is believed to be caused by a third hantavirus. At present, human cases are sporadic and the attack rate is far below that which occurred during the initial outbreak in the Southwest. 11. Spongiform encephalopathy in deer and elk In the United States of America, between March 1981 and October 1994, 33 cases of chronic wasting disease were diagnosed in 28 mule deer (Odocoileus hemionus), 4 elk (Cervus elaphus), and 1 whitetailed deer (O. virginianus). This disease is closely related to scrapie in sheep and bovine spongiform encephalopathy in cattle. In contrast to previous reports of this disease in captive animals, the aforementioned cervids were free-ranging. All cases originated in a cluster in north-central Colorado; surveillance in other areas is ongoing and no cases have yet been found. 12. Undiagnosed disease of cane rats in West Africa The cane rat (Thryonomys spp.) is a wild rodent bred in various countries in Africa for food. However, in certain areas in West Africa, it has become unacceptable as a food item, due to a disease which is characterised by desquamation of the skin. The animal loses all its fur, becomes paralysed and succumbs after several days. The rate of mortality is very high, between 80 and 90%. This species has become very rare, and has even disappeared, according to the inhabitants of these areas. 13. Sarcoptic mange in Europe Sarcoptic mange is still prevalent in red foxes (Vulpes vulpes) in France but the incidence is not known. The United Kingdom experienced an unusually large number of cases this year. An outbreak was mentioned in the Cantabrian mountains in Northwestern Spain, in isolated populations of chamois (Rupicapra rupicapra). Sarcoptic mange is still endemic in Scandinavia involving foxes (Vulpes and Alopex), lynx (Felis lynx), raccoon dogs (Nyctereutes procyonoides), and pine and stone martens (Martes martes, M. foina). SECTION 3 FISH, MOLLI SCAN, AND CRUSTACEAN DISEASES FISH, MOLLUSCAN, AND CRUSTACEAN DISEASES* 1. Diseases and pathogens of fish 1.1. Notifiable viruses listed in the International 1.1.1. Aquatic Animal Health Code Viral haemorrhagic septicaemia In the European Union, viral haemorrhagic septicaemia (VHS) continues to cause significant economic loss in freshwater rainbow trout farms, although there has been a reduction in its occurrence in some countries (e.g. Denmark) due to national programmes aimed at eventual eradication of the disease from trout farms. Following the confirmation of VHS in turbot (Psetta maxima) on a farm on the Island of Gigha, off the west coast of Scotland, United Kingdom, in 1994, clearance and disinfection of the site, in order to eradicate the disease, have been completed. Investigations to examine possible sources of the outbreak have concentrated on tests on commercial marine fish species. To date, VHS virus has been detected in Atlantic cod and haddock from deep sea stocks north of mainland Scotland, indicating that these may constitute a marine reservoir of VHS virus and act as a source of infection for marine fish farms, either via transmission through the water or through the use of wild marine fish (such as cod and haddock) as feed to supplement a pelleted diet. VHSV continues to be isolated from Pacific herring in many areas of Washington, United States of America (USA) and British Columbia, Canada. The fish exhibit symptoms such as haemorrhages, and are found to have levels of virus that would suggest that they are actively infected. The virus was also recovered from healthy returning adult coho salmon in the lower Columbia River of Washington. The North American strain of VHSV was isolated from Atlantic salmon (Salmo salar) farmed in British Columbia in March 1995, based on a specific DNA probe. This is apparently the first time that the virus had been isolated from farmed Atlantic salmon. The virus was isolated from 2 of 30 market-sized fish taken from a marine netpen that had a history of unexplained but increasing fish losses. Extract from the report of the meeting of the OIE Fish Diseases Commission, which was held in Paris from 20 to 22 November 1995. -27- 1.1.2. Infectious haematopoietic necrosis Outbreaks of infectious haematopoietic necrosis virus (IHNV) infection remain common in salmonid fish of the western portion of North America. It appears that rhabdoviruses, especially IHNV, are causing increasing problems in Atlantic salmon held in marine netpens in British Columbia (Canada). The Department of Fisheries and Oceans (DFO) and the British Columbia Ministry of Agriculture, Food and Fisheries are jointly planning a workshop to review the problem. All indications are that the virus is not transferred with the smolts entering the netpens, but rather that farmed fish become infected in the marine environment. Research is being carried out to determine a possible marine source of infection. Herring (Clupea pallasii), tubesnouts (Aulorhynchus flavidus) and pile perch (Damalichthys vacca) are found to be susceptible to the virus in laboratory tests. In Europe, there has been no further spread of the virus beyond the countries of Belgium, France, Germany, and Italy. In Germany, the virus was detected for the first time in the State of Lower Saxony, leading to clearance and disinfection of the single farm affected in an effort to 'stamp out' the disease. The published report of the first detection of IHNV in Spain has been officially refuted by the Veterinary Services of the Spanish Government. 1.1.3. Spring viraemia of carp The situation of spring viraemia of carp in Europe remains stable, although in the United Kingdom during 1995. 14 outbreaks occurred that were linked to illegal imports of fish from other European Union Member States for re-stocking fisheries. The outbreaks resulted in high mortality amongst large carp in affected fisheries. The United Kingdom authorities have taken steps to increase vigilance and enforcement of regulations through veterinary inspections on suspected illegal imports. In Germany (State of Lower Saxony), five cases of SVC occurred in 1995 (compared with none in 1994); three of these were in common carp and two in imported koi carp. 1.2. Other virus infections 1.2.1. Birnaviruses In the United Kingdom, a 2-year programme of testing for infectious pancreatic necrosis virus (IPNV) on all trout farms was completed. The survey revealed the presence of the virus in 4 0 % of the farms in Great Britain, but with little significant disease effect in the majority of these cases. In the State of Lower Saxony, Germany, there was a clear decrease in the incidence of IPN (20% of the previous year's level). In Spain, turbot farms continued to experience mortality in young fish due to infection with aquatic birnaviruses, some strains of which cause IPN in rainbow trout after experimental exposure. Clinical IPN is still the main viral disease problem in Norwegian Atlantic salmon smolts farms, following transfer to sea water, while it is observed occasionally in Sweden (six cases) and Finland (one case). IPN virus serotype Sp was registered in wild Atlantic salmon for the first time in 25 years. In Japan, a new epizootic of yellowtail ascites virus has been demonstrated to cause significant losses in yellowtail (Señóla quinqueradiata) fingerlings. This virus is serologically distinct from IPNV. -28- 1.2.2. Nodaviruses In France, sea bass (Dicentrarchus labrax) hatcheries continued to experience significant larval mortality, due to infection with of viral encephalopathy and retinopathy (VER), a nodavirus that causes vacuolation of brain and retina tissue. During the past year, 1- and 2-year old fish have suffered mortality due to this infection. In Italy, severe mortality in hatcheries and sea bass culture facilities has also occurred due to this viral infection, and a national survey was started in September to determine the geographical distribution of the disease. The disease was also detected in sea bass farms in Greece for the first time, with seven cases being confirmed in the two areas affected. It therefore appears that in the Mediterranean, the disease is becoming more common and of increasing severity with mortality occurring in older fish on some affected farms. In Japan, viral nervous necrosis (VNN) among striped jack (Pseudocaranx dentex) has caused heavy larval mortality, and a similar virus has been found in larval groupers (Epinephelus fuscoguatus and E. akaard) in Taipei China. Another viral encephalopathy and retinopathy resulting in large mortality in farmed halibut (Hippoglossus hippoglossus) was described in Norway. The agent seems to be a nodavirus that cross-reacts with VNN isolates from sea bass and striped jack. The disease has been made notifiable in Norway. 1.2.3. Herpesvirus White sturgeon herpesvirus II remains prevalent at sturgeon hatcheries in California (USA) where it affects skin and gills, resulting in high mortality in juvenile fish. The virus has also been detected in sturgeon in the Columbia River. In Australia, extensive pilchard (Sardinops sagax [neopilchardus]) deaths were reported along the Southern Australian coastline over a 3-month period. Approximately 10% of the adult pilchard population are believed to have died. Mortality was also seen in New Zealand. A herpes-like virus was consistently seen in the gills of affected pilchards. It is believed that the herpesvirus is present as a latent infection until activated by stress. 1.2.4. Infectious salmon anaemia Infectious salmon anaemia is still present in Atlantic salmon in Norway, but as reported in World Animal Health in 1994 (p. 24), has been brought under control by sanitary measures. Only two outbreaks of ISA were registered in 1995. Some farms (eight) in three counties still have restrictions because of the disease, despite the fact that the sites have been emptied of all fish. 1.3. Bacterial infections 1.3.1. Furunculosis The situation regarding classical furunculosis is stable in Finland, Norway and Sweden. In Iceland, an epidemic of classical furunculosis occurred for the first time in 1995 in returning wild Atlantic salmon. The disease was also detected in brown trout. -29- In 1995, there was another outbreak of the 'typical' strain of furunculosis in Nova Scotia (Canada), this time at a freshwater hatchery on the Gulf of St Lawrence coast. This isolate, like the first one detected in Nova Scotia in 1994, was resistant to oxytetracycline and potentiated sulphonamides. The outbreak was finally controlled with emergency drug treatments of florfenicol and enrofloxacin. Surviving fish were allowed to be transferred to sea cages on the Atlantic coast of Nova Scotia (the same harbour where 'typical' furunculosis was detected in 1994). There was no recurrence of the disease in the transferred fish at the sea cage site. 'Atypical' furunculosis in Baie d'Espoir (Newfoundland) sea cage operations has become resistant to all three of the antibiotics approved for use in Canada. This has led to abnormally high losses of salmonids in marine netpen operations in Baie d'Espoir. 1.3.2. Vibriosis Vibrio salmonicida (cold water vibriosis) has been increasing in mid-Norway, probably due to inadequate vaccination, while the number of cases was reduced considerably by use of vaccines in the north of Norway, Canada and New England (USA), compared with previous years. Classical vibriosis caused by Vibrio anguiliarum has been reported to be increasing in Finland and some parts of Norway. 1.3.3. Flexibacteriosis Infection with Flexibacter spp. seems to be an increasing problem in Finland, Sweden and Norway. Flexibacter maritimus was detected in white sea bass, Pacific sardine, and northern anchovy at three separate net pen sites in California, USA. A cytophaga-like organism isolated from netpen-reared chinook salmon could be a similar agent. This organism may also be responsible for outbreaks of 'mouth rot disease' in Atlantic salmon in British Columbia (Canada). Mouth rot disease primarily affects Atlantic salmon smolts in British Columbia within 6 months of entering seawater. Sick fish show lesions in the mouth near the teeth. The causative agent is most likely to be F. maritimus. although it appears that a number of underlying factors must be present for the disease to become established (e.g. viral infections, high salinity during smolt entry to seawater). Farmers feel that this disease is more apparent now because a number of other diseases (e.g. furunculosis) are better controlled following widespread vaccination programmes. Losses associated with mouth rot are usually less than 5%, however, the loss of productivity due to reduced feeding, drug treatments, etc. can be significant. 1.3.4. Bacterial kidney disease In Norway and Sweden, the number of affected farms has been reduced by established sanitary control measures. The use of ELISA for detection of Renibacterium salmoninarum has shown that it is likely that all populations of salmonid fish in North America harbour some level of the bacterium. The bacterium and the resulting disease are also widespread in Chile. 1.3.5. Streptococcosis Recent and continuing reports of several as yet unknown diseases in Europe, involving Enterococcus seriolicida-\ike cases in turbot (Spain) and rainbow trout (Italy) and Vagococcus salmoninarum in trout (France), have shown the increasing incidence of chronic and costly infections caused in rather large fish by Gram-positive cocci. Treatments do not seem to be effective in such cases. -SO- LS.6. Piscirickettsia infection Piscirickettsia salmonis remains the most important pathogen of salmon in Chile. A freshwater strain of the organism was reported from large rainbow trout reared in cages in Lago Llanquihue in southern Chile. The bacterium was confirmed by the fluorescent antibody technique. Fish showed pale gills, lethargy, mottled liver, swollen kidney, enlarged and mottled spleen, and the empty gut typical of the disease when it occurs in salt water. Mass mortality caused by a Rickettsia-like in cultured tilapia in Taipei China. microorganism was continuously experienced Parasites 1.4.1. Ectoparasites Ichthyophthirius multifilis (Ich) infections were very severe in adult sockeye salmon (Onchorynchus nerka) returning to some of Canada's west coast Salmonid Enhancement Programme spawning channels in 1994 and 1995. The parasite infestations led to significant pre-spawning losses in the channels. The occurrence of Gyrodactylus salans in wild populations in Norwegian rivers is gradually being brought under control through eradication measures. Four farms are, however, still under restrictions. G. salaris has been reported from northern Finland where it is considered to be a major threat to the Tana river system. There has been an increase in the problems caused by sea lice (Caligus spp. and Lepeophtheirus spp.) in Atlantic salmon marine farms in the Bay of Fundy (Canada). Losses due to sea lice for the 1995 growing season are projected to reach CAD 20 million. Re-infection rates following treatment were high, due to warm water temperatures. Field and laboratory trials are being conducted with pyrethrin and hydrogen peroxide to determine effective procedures for treatment, and to obtain data (e.g. impact on non-target organisms) that could be used to support requests to register these chemicals as pesticides for use in aquaculture. In October 1995, Salmosan (azamethiphos) was approved for temporary use on an emergency basis to treat sea lice in Atlantic Canada. Early reports indicate that sea lice removal rates with Salmosan are higher than those recorded with other treatments. The salmon louse is still the main parasitic problem of concern in fish farming in Norway. 1.4.2. Endoparasites Proliferative kidney disease (PKD): The parasite continues to spread in Belgium and to cause significant economic loss to trout farms in the United Kingdom (estimated annual loss GBP 1.5 million) and France. PKD was found in Newfoundland (Canada), for the first time in a commercial aquaculture operation. PKD had only previously been detected in Newfoundland in a natural population. The most significant finding for the USA has been the widespread detection of Myxobolus cerebralis, the causative agent of whirling disease in Montana and Colorado. Some infected wild stocks have shown significant declines in the last several years. Trematodes. Mass mortality caused by a blood fluke, Paradeontacylix, amberjack (Serióla dumerilï) exported from China to Japan. occurred among -31 - 1.5. Diseases of uncertain aetiology The aetiology of the condition 'M74' that has been reported to cause considerable mortality in the offspring of wild Atlantic salmon in the Baltic sea seems to be solved: thiamine deficiency has been mentioned as a primary factor in this disease complex. Bathing of the sac fry in a thiamine solution has considerably improved the survival of the fry. The reason for the thiamine deficiency is still not clarified, but it may be due to the feeding regime of the salmon in the Baltic sea. Whether it is a nutritional problem or some sort of intoxication is to early too say. The rosette agent, a possible flagellate, has produced severe systemic infections in chinook salmon in California, USA. 2. Diseases and pathogens of molluscs 2.1. Viruses In France, there have been no significant new developments in the epidemiological situation of the herpes-like virus infection of juvenile oysters, either in hatcheries or natural beds. Abnormally high summer temperatures are still believed to be the principle reason for the manifestation of the virus disease in the past 2 years. 2.2. Parasites In Europe, no further spread of bonamiosis and marteiliosis has been reported. No parasites listed in the International Aquatic Animal Health Code were reported from the North American east coast shellfish. Mikrocytos mackini has still only been found on the west coast of Canada. In Canada, a protozoan of unknown taxonomic affinities (called SPX) has sporadically occurred in cultured Japanese scallops (Patinopecten yessoensis) and caused mortality approaching 100% in juveniles less than 3 cm in shell height. All ages of scallops are susceptible to infection, but direct transmission between scallops is limited. The flagellated stage of SPX, which develops in the tissues of about 15% of the infected juvenile scallops, has ultrastructural features reminiscent of Perkinsus spp., but the thioglycollate culture test that is diagnostic for Perkinsus spp. is negative for SPX. Results of preliminary field studies indicate that SPX is enzootic to British Columbia with Japanese scallops serving as accidental and, in most cases, dead-end hosts. The erratic occurrence of SPX was reconfirmed when high prevalence of infection and mortality (84%) occurred in naive Japanese scallops at an experimental site in Kanish Bay, British Columbia. Only 10% of the same stock of scallops at a commercial grow-out site in the same bay. and within 1 km of the experimental site, became infected and mortality was not detected. 2.3. Diseases of uncertain aetiology In France, abnormal mortality, mainly in young oysters, has continued in some coastal areas. The mortality has been associated with unusually high water temperatures and dense blooms of phytoplankton (Gymnodinium spp.) this year. Similar mortality has occurred in Pacific oyster (Crassostrea gigas) populations in Ireland and the Netherlands. Extensive histological examinations of oysters from affected areas have failed to produce any evidence for an infectious aetiology. -32- Diseases and pathogens of crustaceans 3.1. Viruses Diseases of cultured shrimp were very serious, resulting in high economic losses in 1995 in such countries as China, India, Indonesia, Japan, Philippines, Taipei China, and Thailand. The most serious disease, white spot disease, was confirmed to be caused by a baculovirus which has been named white spot disease virus. Taura syndrome is a devastating necrotising disease of the cuticular epidermis, foregut, hindgut, and connective tissues on white shrimp. Outbreaks occurred this year in Texas and Hawaii (USA) as a result of movement of infected shrimp. The disease was first discovered in Ecuador, and has spread to other countries of Central and South America. The disease is caused by a picorna-like virus and causes losses approaching 95-100% among affected stocks of shrimp. Another picornavirus, infectious hypodermal and hematopoietic necrosis virus, is established among wild penaeids shrimp in the Gulf of California (Mexico). The virus has been spread worldwide by the movement of infected shrimps. 3.2. Bacteria The Texas (USA) shrimp industry continues to have significant losses due to a necrotising hepatopancreatitis caused by an unidentified Gram-negative intracellular bacterium that cannot be cultured by conventional methods. The disease occurs at salinities greater than 20 parts per thousand and is exacerbated at temperatures above 30°C. 3.3. Parasites Bitter crab syndrome, caused by a parasitic dinoflagellate, continues to spread in populations of Tanner crabs in southeast Alaska (USA). Infected crabs suffer high mortality and surviving animals are unmarketable due to poor flesh quality. The cause of a 'new' disease, reported in prawns (Pandalus platyceros) from Powell River, British Columbia, Canada in the fall of 1991, was identified as a Hematodinium-Uke protozoan. The confirmed distribution consists of one area in the northern part of the Strait of Georgia. Over the past 3 years (1992-1994) the highest prevalence at the most heavily affected location in Malaspina Strait was 29.6% (4.6% gross and 24.0% subclinical) in late August 1993.

Ce programme est également soutenu par le fonds zoosanitaire. -36- A L L E M A G N E INTRODUCTION En 1995. les autorités vétérinaires allemandes se sont donne comme priorités la protection et la santé animales et la lutte contre les epizooties. Malgré leur complexité, ces notions ont été perçues comme faisant partie d'un même ensemble. Dans cette entreprise, il est à constater l'aide grandissante apportée par les organismes créés ces dernières années (par exemple, le comité national de crise pour la lutte contre les epizooties). I.

Au total, 52 foyers ont été constatés dans des élevages de porcs répartis dans cinq Lânder. Pour 65 % de ces foyers, il s'agit de cas rencontrés durant le premier semestre de 1995. Deux régions ont été particulièrement touchées. On a répertorié 32 incidents en Basse-Saxe, zone à forte densité de population porcine et 13 dans la région de Mecklembourg-Poméranie Occidentale où la maladie a aussi sévi chez les sangliers. Plus de 85 000 animaux ont été abattus dans les 52 élevages touchés. Par ailleurs, plus de 120 000 porcs ont été éliminés à titre préventif dans 331 autres exploitations. L'apparition de la peste porcine classique a essentiellement été liée aux facteurs suivants : acquisition d'animaux en phase d'incubation de la maladie ; infections transmises du fait du voisinage rapproché entre exploitations ou de contacts directs ou indirects avec des sangliers. Ces dernières années, on avait souvent observé que l'infection était transmise par l'ingestion de déchets alimentaires crus ou insuffisamment cuits. Ce type de transmission a été totalement enrayé en 1995. 12-94 12-94 i j 1 •37- En 1995, comme durant les années précédentes, deux souches de virus ont été détectées, l'une d'entre elles étant exclusivement localisée dans les Lânder de Mecklembourg-Poméranie Occidentale et de Brandebourg. L'abattage sanitaire de tous les porcs des exploitations concernées, l'abattage des porcs présents dans les élevages en contact ou dans le voisinage et la gradation des mesures de contrôle selon des zones de 3, 10 ou 20 km de rayon autour de chaque foyer ont permis de lutter avec succès contre la maladie. Dans certains Lânder, comme la Rhénanie-Palatinat depuis janvier 1995. et la Basse-Saxe depuis février 1995, la peste porcine a cessé d'affecter les sangliers. En revanche, un nouveau foyer est apparu dans le Brandebourg. 2. Maladie de Newcastle Vingt-huit foyers ont été constatés en 1995. soit 15,6 % du nombre total pour l'année 1994. Ils étaient répartis sur sept Lander ; la plupart des foyers avaient une faible ampleur et concernaient moins de 200 animaux À l'évidence, cette baisse sensible du nombre des foyers résulte de la vaccination obligatoire des poulets et des dindes qui a été mise en place fin 1994 et qui s'applique à tous les élevages, quelle que soit la taille de l'effectif il. MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Maladie d'Aujeszky La maladie d'Aujesky a été complètement éradiquée dans quatre Lânder (Mecklembourg-Poméranie Occidentale, Brandebourg, Thuringe et Saxe) , dans les douze autres Lânder, l'éradication sera bientôt atteinte. En 1993, on constatait 446 foyers ; en 1994, 24Í. Il n'en restait que 60 en 1995. 2. Rage En 1994, le nombre des cas de rage avait augmenté comparativement aux années antérieures. Des campagnes d'immunisation de grande envergure, accompagnées d'une chasse intensive du renard, ont fait à nouveau reculer la rage en 1995. C'est ainsi qu'en 1995 on n'a constaté que 855 cas de rage (contre 1 359 en 1994) répartis dans 189 communes (418 en 1994). Sur ces 855 cas, on compte 159 animaux domestiques (19 % ) , en majorité des bovins, et 696 animaux sauvages (81 % ) . Le renard représente 73 % des cas de rage chez ces derniers. -38- A R G E N T Î N A I.

Se cumplió de esta manera con las metas previstas por el Plan Nacional de Erradicación de la Fiebre Aftosa emprendido en 1990. Este Plan constituyó una prioridad para la Nación Argentina y en él se volcaron los esfuerzos de toda la sociedad en general y de los sectores ligados a la producción en particular. La estrategia de la lucha contra la fiebre aftosa la determina el Servicio Nacional de Sanidad Animal (SENASA) según lo establece el art. 2° de la Ley 24.305 denominada "Ley Aftosa". Los ejes en los que está basada la campaña incluyen la inmunización de la totalidad de los animales, el control de la faena (la matanza), el control de movimientos de hacienda, el sistema de vigilancia epidemiológica y el sistema de atención de situaciones emergenciales. La campaña de vacunación involucra a los agentes contratados por el sector privado a través de 350 Comisiones Zonales de Sanidad Animal (CZSA), que en 1995 vacunaron una vez a los animales mayores de dos años y dos veces a los menores en dos campañas de vacunación en la que visitaron a 280.568 establecimientos ganaderos de la zona de vacunación. Esta forma de operar permite asegurar la cadena de frío ya que las CZSA son las responsables de la compra directa de la vacuna al laboratorio productor. En la formulación de las vacunas se incluyen las siguientes cepas de virus aftoso: A Argentina 87, C Argentina 85, 0 ¡ Caseros, todas con adyuvante oleoso, utilizando cada laboratorio distintos componentes. La vacuna antiaftosa es producida por los laboratorios privados y todas las series elaboradas son controladas por el laboratorio oficial. En 1995 se aprobaron 108.651.555 dosis de vacuna antiaftosa. 3 07-94 -39- El Estado Nacional, a través de las 309 oficinas locales del SENASA efectúa un estncto seguimiento y fiscalización de las tareas. Aquellos establecimientos que no cumplen con los requisitos de vacunación son conminados a hacerlo bajo apercibimiento de multas y de realizar la vacunación en forma compulsiva mediante orden judicial. ES control de los movimientos de hacienda se optimizó mediante la implementación de un sistema documental único y mediante ¡a ejecución de 821 operativos de control en las principales rutas del pais, durante los cuales se detectaron 476 irregularidades, donde se labraron actas de infracción. Existen 28 puestos fijos de control en los accesos a las regiones con estatus sanitarios diferenciales (Patagonia y Mesopotamia) y puestos de control en los accesos terrestres al país, los que sumados a los controles de puenos y aeropuertos garantizan el no ingreso de productos capaces de vehiculizar el virus de la fiebre añosa El sistema de vigilancia recae en la estructura del SENASA y de las 350 CZSA privadas que en las dos visitas que realizan a cada establecimiento toman datos que alimentan al sistema de vigilancia. Los veterinarios de la actividad privada, integrados en un sistema de registro oficial, los productores, especialmente sensibilizados ante la más mínima sospecha de la enfermedad, los transportistas y eí servicio de inspección prefaena, son algunos de los puntos por los que se recibe la información de notificaciones o sospechas de la enfermedad, de las que se atendieron 84 en 1995 También el muestreo serológico para la detección de anticuerpos VIAA y de protección es empleado para la detección precoz de situaciones de riesgo, tanto por actividad viral como por baja en las defensas inmunitanas contra la enfermedad. Eí sistema de atención de situaciones emergenciales está desarrollado para actuar frente a cualquier situación de riesgo para la salud pública o para la sanidad animal, mediante la implementación inmediata de acciones preventivas. Ante situaciones de riesgo la legislación argentina, que dispone de una Ley Nacional de Lucha contra la Fiebre Añosa, prevé la ejecución de rifle o sacrificio sanitario, cabe recordar que el mismo fue implementado por última vez en focos de enero de 1994 en San Carlos de Banloche, Provincia de Río Negro, cuando se aplicó el rifle sanitario a 8.286 ovinos y 565 bovinos. I capnno y 1 camélido, resarciéndose a los propietarios mediante el pago de un monto indemnizatorio 2. Lengua azul Hasta ahora no fue diagnosticado nunca en la Argentina,"no obstante en 1995 se detectaron casos de positividad serológica a orbivirus en el Nordeste de! país. Se está realizando un estudio epidemiológico tendiente a determinar la causalidad de las reacciones serológicas, la extensión de los posibles vectores a orbivírus y a lograr el aislamiento del virus y su tipificación. Se categorizó según las características bioecológicas a la probabilidad de existencia de vectores de orbivírus a las distintas zonas del país, determinándose que por los regímenes pluviales y las temperaturas la mayor parte de la ganadería argentina estaría en zonas de muy bajo riesgo, quedando un área restringida ai nordeste del pais en la que existiría la posibilidad de existencia de vectores. Hasta el momento la presencia de animales seropositives parece limitada sólo a algunos departamentos del Nordeste del país, no habiéndose detectado casos clínicos en las especies susceptibles siendo de destacar la fuerte presión de vigilancia ejercida sobre éstas. 3. Peste porcina clásica En 1995 se registró un solo foco de la enfermedad que fue controlado mediante aislamiento, sacrificio de los 105 animales involucrados y vacunación en anillo. Las bases del programa se centran en la vacunación obligatoria, con vacuna aprobada por el Laboratorio Oficial del SENASA a los 45 días de vida de los lechones y cada seis meses a los reproductores y en caso de movimiento de animales con destino distinto de la faena y en un sistema de vigilancia epidemiológica con los mismos componentes y características que para fiebre añosa. La Resolución 225/95 del SENASA constituye una estricta reglamentación sobre las condiciones de tenencia y crianza de porcinos como parte de las medidas de prevención de esta enfermedad, de la fiebre añosa y de las zoonosis. En cumplimiento de esta Resolución, SENASA realizó durante 1995 28 operativos de los que resultaron sacrificados 3.878 porcinos cuyas condiciones de crianza no se adecuaban a las reglamentaciones vigentes. -40- 4. Enfermedad de Newcastle Las acciones de lucha contra las enfermedades de las aves se realizan en forma mancomunada entre los distintos actores en lo que se denomina Plan Nacional de Sanidad y Mejora Avicola. el que es coordinado por el SENASA y del que participan todos los actores del sector avícola: Estado Nacional y provinciales, sector primario de la producción, industria y comunidad científica a través de la Comisión Nacional de Sanidad Avícola creada mediante ía Resolución 1.462 de) 16 de diciembre de 1994. El sistema de vigilancia activa contra las enfermedades se sustenta en el Estado y en la actividad privada, en lo que hace a programas de campo, se destacan las actividades del Programa Nacional de Erradicación de las Micoplasmosis Aviares instrumentado mediante ia Resolución 1.248 del 20 de noviembre de 1993, Anexo I I , la inspección oficial de las plantas de faena poi parte del SENASA y el sistema de red de laboratorios implementado mediante la Resolución 1.357 del 27 de diciembre de 1993, Anexo 12 No se detectan focos de cepas velogénicas desde 1987. A efectos de consolidar esta situación durante 1995 se incrementaron las acciones de vigilancia epidemiológica mediante la incorporación de los laboratorios privados de diagnóstico de patologías aviares al sistema de información de luchas sanitarias y mediante la instrumentación de controles en el marco de un plan integral de sanidad avicola. En lo que hace a) uso de vacunas, están prohibidas en la Argentina las vacunas vivas realizadas a partir de cepas mesogénicas o velogénicas En 1995 Argentina fue incluida en la lista de terceros paises habilitados para exportar productos avícolas a la Union Europea. IL E N F E R M E D A D E S DE LA LISTA B Enfermedades i. de bovinos Brucelosis bovina El Programa Nacional de Control y Erradicación de la Bruceíosis Bovina basa su accionar en la vacunación de las terneras con cepa 19, el control del movimiento de reproductores y la erradicación a nivel de los establecimientos por parte de veterinarios privados acreditados por el SENASA. El objetivo del plan es la erradicación de la enfermedad de todo el territorio nacional. La estrategia de ímpiementación contempla la instrumentación según los medios con los que se cuente para cada caso y sector. Como medida de obvia y global aplicación, la vacunación obligatoria y efectiva de las terneras con cepa 19 es una medida que, si bien no apunta a eliminar la enfermedad, permite bajar su velocidad de dispersión al disminuir la probabilidad del aborto, que es la casi excluyeme fuente de contagio tanto al hombre como al resto de los animales del rodeo, ésta se instrumenta a través de planes especiales de vacunación ejecutados por vacunadores contratados por las fundaciones de sanidad animal. En la actualidad se encuentran trabajando 169 planes especiales de vacunación, involucrando a 117.310 productores y 3.558.951 terneras, el registro total de vacunación de terneras ascendió a 4.219.025 terneras en todo 1995. En lo que hace al control de reproductores, la difusión de la enfermedad se realiza mediante el control serológico de los reproductores movilizados según lo establece la Resolución 189/95 del SENASA. En la población de tambos los datos generados por las usinas lácteas muestran que la mayoría de los tambos tiene series importantes de registros negativos en anillo en leche, lo que evidencia el trabajo realizado por los productores y los veterinanos privados. Esta información será oficializada mediante la implementación de convenios con las industrias del sector, las que coadyuvarán a la erradicación de la enfermedad de ese ámbito de la producción. Otro de los ejes del programa son la capacitación e incorporación al sistema oficial de los veterinarios privados mediante un sistema de acreditación en el que participan las universidades de veterinaria de todo -41 - el país. Los registros de médicos veterinarios acreditados para el saneamiento de la enfermedad alcanzan a 1.118 profesionales. Encefalopatía espongiforme bovina La República Argentina es país libre de encefalopatía espongiforme bovina. No solamente nunca se registraron casos de la misma, sino que se realizaron investigaciones que asi lo demuestran. Las acciones de prevención del mal se iniciaron en 1990. resultando para la Argentina esencial y prioritario mantener la situación de estatus de país libre de la enfermedad. La vigilancia y notificación de las situaciones sanitarias emergentes se implementa a través del Sistema Nacional de Vigilancia Epidemiológica Este sistema se ve reforzado desde los distintos programas de lucha como ser el Programa de Erradicación de la Fiebre Añosa a través de las campañas de vacunación. Programa de Lucha contra la Brucelosis a través de los veterinarios de la actividad privada integrados en un sistema de Registro Oficial de Acreditación que mantienen un permanente contacto con la hacienda susceptible, así como en las plantas faenadoras donde se realiza una inspección individual ante y post mortem y extracción periódica de muestras para examen histopatológico. Fundamentos sanitarios relacionados a la salud animal, humana y a la comercialización, hacen imprescindible ei mantenimiento de la condición de país libre, por ello se realizaron las siguientes acciones preventivas: - Prohibición de mgreso de animales de países afectados de la enfermedad (Resolución SENASA 429/90). Vigilancia epidemiológica activa, basada en el análisis de muestras de cerebros de animales de campo muertos con síntomas nerviosos o extraídos de animales arribados a frigoríficos con los mismos síntomas, la que se está desarrollando en forma continua desde 1993. - Seguimiento de ios reproductores importados a partir de 1980 desde países en los que luego del ingreso se presentaron casos de la enfermedad, actividad ésta desarrollada en forma continua desde 1993. - Prohibición del uso de harinas de carne y hueso de origen rumiante en el alimento balanceado para alimentación de rumiantes (Resolución SENASA 252/95). - Normalización de las importaciones de animales, semen, embriones, carne, leche y derivados desde países con distintas situaciones sanitarias respecto de esta enfermedad (Resoluciones SENASA 294/95 y 382/95). - Registro Nacional de Reproductores bovinos importados con seguimiento de los animales desde su ingreso hasta su muerte con destrucción obligatoria de los cadáveres (Resolución SENASA 471/95). -42- A U S T R A L I A INTRODUCTION The management of animal health issues in Australia is undergoing fundamental change with the formation, in 1995, of the Australian Animal Health Council (AAHC). The AAHC is a non-profit company limited by guarantee, established under Australian corporations law and accountable to the Australian Secunties Commission. Its shareholders are the Commonwealth and State/Territory Ministers with agricultural responsibilities as well as the Presidents of the peak national councils of Australia's livestock industries. The A.AHC has been established to give a higher profile to, and broaden the input base for animal health planning in Australia. It will be the peak anima! health body, the point of reference for strategic policy development, foi national program funding and for animai health matters that require negotiation and resolution The AAHC will monitor the standards of animal health service provision in Australia. The AAHC was formed following a review of animal health services in Australia. This review, as well as recommending the formation of the AAHC with both industry and government representation, identified 7 core functions in animal health that were required at a national level, in summary, these are: disease surveillance, diagnosis, reporting, prevention, control and eradication; policy development in animal health, veterinary public health and animal welfare; negotiation of trade protocols, development of standards and certification for export; exclusion of exotic disease; maintenance of professional standards and expertise: development of national codes of practice for animal care, husbandry, welfare and veterinary public health; national registration of veterinary chemicals and biologicals. Following the release of the review's findings, a working group was formed to establish principles and develop a business plan for the operation of the AAHC.

Comprehensive serological, virological and insect monitoring programs are routinely carried out. In 1995. the national arbovirus monitoring program detected activity in ten sentinel cattle herds in Northern Australia. Serotypes 20 and 21 were isolated in the Northern Territory, while serotypes 1 and 21 appear to be the ones circulating in Western Australia and Queensland. 2. Highly pathogenic avian influenza (fowl plague) Australia is again free of virulent avian influenza All restrictions were lined in February 1995, following an outbreak, in December 1994 on a single isolated poultry farm in south-east Queensland. IL LIST B DISEASES Diseases of multiple 1. species Johne's disease (paratuberculosis) Johne's disease continues to be of concern in Australia Work is proceeding on the development of a National Johne's Disease Market Assurance Program. The program will be voluntary, aimed at reducing disease spread. Properties will be classified by status based on herd history and testing/management requirements, backed by vendor declarations. Diseases of cattle 2. Bovine tuberculosis Australia was declared impending free from bovine tuberculosis on 31 Decemeber 1992. This means that all cattle herds have been assessed, with no known infected herds. Because of the nature of the disease, tuberculosis breakdowns will still occasionally occur and monitoring is continuing. In 1995 there were 8 herd breakdowns. Surveillance is based on abattoir monitoring through carcase inspection. A National Granuloma Submission Program has been in place since March 1992 at all export and domestic abattoirs. All granulomas from the thorax and those from other parts of the body indicative of tuberculosis are required to be submitted for laboratory analysis. Diseases of horses 3. Japanese encephalitis In 1995, Japanese encephalitis was reported for the first time in Australia. It was diagnosed as the cause of death of two people on Badu Island (population approx. 780) in the Torres Strait. A third human case recovered. Extensive serological testing found 20 people, 12 out of 12 pigs, and 9 out of 10 horses on the island seropositive. Serological testing found cases of exposure to the virus in people on islands adjacent to Badu, but clinical and seological surveillance confirmed that there was no evidence of Japanese encephalitis in humans or animals on continental Australia. No further clinical cases occurred in the Torres Strait. It is thought that the outbreak occurred as a result of migrator}' water birds infecting local mosquito populations. Diseases of 4. lagomorphs Viral haemorrhagic disease of rabbits In 1995 rabbit calicivirus the cause of viral haemorrhagic disease (VHD), which was under test as a biological control agent for rabbits, escaped from quarantine on Wardang Isaland, South Australia. On 4 -44- October 1995. rabbits with VHD were found at two sites outside the trial area. On 15 October, VHD was confirmed in a rabbit on the mainland, adjacent to Wardang Island. Despite the implementation of pre­ existing contingency plans to eradicate the disease, it continued to spread in wild rabbit populations. By mid-November, it had established around Yunta, the Flinders Ranges, and Port Augusta in South Australia and in two areas outside Broken Hill in New South Wales. Because of the large areas involved plans to eradicate the disease were abandoned. Vaccine has imported for commercial use to protect pets and commercial rabbit colonies. By December. VHD had spread to south-western Queensland and consultations were underway for future controlled releases of the virus i n . OTHER DISEASES 1. Ostrich fading syndrome An extensive investigation was undertaken following the deaths of ostriches in Western Australia, Queensland, New South Wales and Victoria. The syndrome mainly affected birds between one week and 4 months of age. with mortality rates on individual properties up to 50%. As these deaths were reponed following the arrival of imported ostriches in January 1995, there was some concern that an exotic infectious agent may be involved. The investigation, which included a retrospective cohort study, found that the syndrome was not caused by any of the main exotic diseases of poultry, and that it had been present in Australia before the arrival of the imported birds. Extensive testing by Commonwealth and State veterinary laboratories had not identified any infectious agent associated with the syndrome. A review of the literature found that the syndrome is present in most other countries where ostriches are raised. It appears that the most likely predisposing cause of the syndrome is stress, associated with transport, weather conditions, and intermixing with other chicks. 2. Pilchard mortalities On 22-23 March, 1995, the first reports of widespread pilchard deaths were received from the Great Australian Bight and in waters south of Kangaroo Island. Subsequently, over the period April-June 1995, reports were received from a number of locations along the southern Australian coast as deaths spread east and west, and off the west coast near Geraldton, Western Australia, and the east coast near Noosa, Queensland, and the east coast of Tasmania. Kills were also reported off the east coast of the North Island of New Zealand. Surveys in Western Australia indicate that between 8% and 3 0 % of adult pilchards were affected with schools of apparently healthy adult pilchards being reported in previously affected areas. No other aquatic species, including predators, appeared to have been affected. The ultimate cause of death was anoxia resulting from gill damage. A Pilchard Mortality Task Force was assembled on 10 May 1995 under the aegis of the Consultative Committee for Exotic Animal Disease in response to reports that mortalities had occurred over an increasingly wide geographic area. The Taskforce concluded that the underlying causes of the mortalities were complex and related to a number of factors. A likely hypothesis is that the initial factors involved stress associated with environmental changes coupled with agents such as a herpes-like viral infection and/or amoebic infestations. While it cannot be discounted, no evidence for or against the implication of an exotic pathogen in the pilchard mortalities was found. There do not appear to have been any significant mortalities after the initial occurrence in a given area, contrary to what one would expect to occur in an epidemic of an infectious disease. Large scale fish kills are not unknown, and have been reported from many different parts of the world. 45- 3. Equine morbillivirus infection In 1995, there was a second human case of equine morbillivirus (EMV) infection. This hitherto unknown infectious disease was first reported from Brisbane. Queensland in 1994. In this outbreak, which occurred in the period 7-21 September 3 994, 14 racehorses associated with one racing stables at Hendra, Brisbane, died after showing acute respiratory illness. A further 7 horses that were infected were subsequently euthanased. Two persons at the stables also contracted the disease, and one of these subsequently died. The cause of this outbreak was found to be a new morbillivirus only distantly related to other members of this virus genus. The latest case, a 35 year old farmer from Mackay in northern Queensland, who died on 21 October 1995, first became ill some 12 months ago with meningo-encephalitis. Although he appeared to have recovered he was admitted to hospital with signs of encephalitis Evidence of equine morbillivirus infection in the patient was based on the finding of a high serum neutralising antibody titre against the virus and a positive polymerase chain reaction test on cerebro-spinal fluid collected before his death. The man had assisted at autopsies on two horses which had been destroyed on the farm in August 1994. These horses had been diagnosed at the time as having avocado poisoning and snake bite envenomation respectively. Direct fluorescent antibody and PCR tests on fixed tissue blocks from the latter horse have confirmed that it was infected with EMV Extensive investigations were undertaken to trace all horse movements onto and off the farm since 1 July 1994 No link with the Hendra outbreak was found. All domestic animals on the farm including horses, goats, cats, dogs, turkeys and geese were tested. Wildlife species on the farm and in nearby areas were also sampled. There was no clinical signs or any serological evidence of EMV found. Since 23 October 1995, the Queensland veterinary authorities have sampled over 3300 animals from 300 populations on horse premises, race meetings, horse events and mixed enterprise farms. Horses have been the prominent species sampled, but other domestic species including poultry and wildlife have been sampled. This is in addition to the serological survey of over 2000 horses was undertaken in 1994 after the September Hendra outbreak. This intensive surveillance program found no evidence of EMV infection in any animal species. The source of the infection remains unknown. Surveillance of wildlife by Queensland veterinary authorities is continuing. 4. Kangaroo blindness syndrome in 1995 there were many reports of 'blindness' in kangaroos, from South Australia, north-west Victoria and south west New South Wales. The condition, referred to as 'kangaroo blindness syndrome', mainly affected Western grey kangaroos, but a small number of cases were reponed in Eastern grey kangaroos, red kangaroos and euros in New South Wales. There is documented evidence that kangaroo blindness syndrome has been around for decades and severe clinical cases, as recently seen, may be due to multiple factors e.g. severe drought. There is no evidence that other animals or humans are affected. Clinically, affected kangaroos are simply blind and stumble into bushes and other objects, especially when disturbed. Otherwise, they are apparently normal, can hear, move and feed freely, and generally maintain body condition. The lesions seen in kangaroos are characteristic of a localised viral infection which affects the retina and optic tracts and the central nervous system. Laboratories have consistently isolated and detected two viruses in the eye tissues of affected kangaroos. They are both members of the Orbivirus family of viruses, one belongs to the Wallal serogroup and the other to the Warrego serogroup of Orbiviruses. Both these serogroups have been recognised for many years as viruses that infect marsupials, but neither has been incriminated before as the cause of any disease in any species. Experimental transmission tests to kangaroos were undertaken at Elizabeth Macarthur Agricultural Institute (EMAI), in New South Wales. Disease symptoms consistent with those seen in the field have been reproduced. Histopathology findings indicated similar changes to field cases though they were milder and experimental animals were not pathologically blind. EMAI concluded that blind field kangaroos are probably chronic cases or represent a small percentage of clinical manifestations. -46- A U S T R I A I.

The outbreak occurred in a pig breeding unit with 35 animals. A total of 3 pigs died and 32 pigs were destroyed. The source of infection was garbage feeding. Movement controls on pigs were introduced in the affected areas and measures in accordance with Directive 80/217/EEC (amended by 93/384) were carried out. A total of 666 blood samples from a 3-km protection zone around the infected holding and 1,519 blood samples from a 10-km surveillance zone were serologically examined with negative results. A total of 607 blood samples from in-contact farms in the protection zone and 1,505 blood samples from incontact farms outside the zones were serologically and virologically examined with negative results. All clinical examinations in the protection zone, the surveillance zone and in-contact farms were negative. No more outbreaks were reported up to the end of 1995. In wild boar In Gansemdorf district. Lower Austria province, in a 454 ha mostly wooded hunting area, directly bordering Slovakia, with about 20 wild boar, classical swine fever was diagnosed in 1 animal found dead. Inside this hunting area no domestic pig holding farms exist outside this area, in Drôsing village, there are 7 pig holding farms. No classical swine fever signs were detected in swine kept in these farms. Measures according to Art. 6 of Directive 80/217/EEC and enforced hunting of wild boars were carried out. 09-94 IL LIST B DISEASES Diseases of multiple 1. species Auieszky's disease To obtain additional guarantees, in accordance with An. 10 of Directive 64/432/EEC relating to Aujeszky's disease, screening was carried out. in 1995, seroreactors were found in 19 holdings. 1 holding in Cannthia (Wolfsberg district) and 18 in Lower Austria (Krerns district: 15, Holiabrunn district 1, Zwettl district: 1.

Malgré ces difficultés, le Service vétérinaire du pays prend toutes íes mesures possibles pour la surveillance et l'éradication des maladies les dangereuses pour les animaux domestiques. Il faut remarquer que les changements politiques et économiques qui ont eu lieu dans les pays de l'Europe de l'Est et dans les ex-républiques d'URSS durant ces cinq ou six dernières années ont fixé de nouveaux objectifs aux Services vétérinaires de ces pays et créé pour eux de nouvelles tâches. C'est pourquoi il est essentiel de coordonner les efforts des Services vétérinaires de tous les pays de la région dans le domaine de la surveillance des rnaiadies infectieuses. .Afin de discuter des problèmes existants, la réunion des Chefs des Services vétérinaires des ex-républiques d'URSS, des pays baltes et de la Bulgarie a eu lieu entre Se 17 et le 20 avril 1996. à Bakou, sous l'égide de l'OIE et en présence de son Directeur général le Docteur J. Blancou. et du Président de la Comission régionale de l'OIE pour l'Europe, le Docteur N.T Beiev ï.

La vaccination des volailles est imposée depuis 1993, excepté pour les unités de moins de 100 oiseaux. Les mesures spécifiques suivantes ont été prises dans les troupeaux amateurs touchés : - mise à mort et destruction des volailles vivantes ; - destruction des carcasses ; - isolement pendant 60 jours après la disparition des symptômes en cas de foyer dans un pigeonnier ; - délimitation d'une zone de protection de 500 mètres autour des foyers et vaccination dans et autour de ce périmètre et interdiction des mouvements ; - contrôle de l'état vaccinal ; - enquête épidémiologique, contrôle des marchands impliqués dans la dispersion du virus ; - mesures de nettoyage et de désinfection.

Le degré d'infection de 1,13 % en 1987 est tombé à 0,08 % au 31 décembre 1992 et a 0.01 % au 31 décembre 1993 et au 31 décembre 1994. Au niveau incidence, le résultat est parallèle, de plus de 500 cas déclarés en 1987. on est passé à 159 cas en 1992, 78 cas en 1993, 36 cas en 1994 et 56 cas en 1995. L'augmentation de l'incidence de la maladie en 1995 est en partie due à des problèmes liés à l'importation de bovins porteurs de Brucella et à des problèmes locaux dans les provinces de Limbourg et de Flandre orientale. 2. Leucose bovine enzootique Le taux d'infection du pays est très faible. Le plan de dépistage et d'éradication accéléré de la leucose bovine enzootique approuvé par la CEE et commencé en 1989 est achevé. 3.

Trente communes ont été infectées, toutes situées dans les provinces de Luxembourg et de Namur. 4. Tuberculose bovine La qualification est suspendue pour moins de 0,02 % des troupeaux. Le contrôle de la situation est assuré par la tuberculination à l'achat d'animaux d'élevage ou de rente et par les contrôles post mortem dans les abattoirs. Une résurgence de la tuberculose est apparue fin 1995. dans la province de Liège. 52- 5.

Les taux de vaccination ont connu d'importantes hausses contre la pénpneumonie contagieuse bovine surtout, mais un léger tassement s'observe au niveau de la vaccination contre la peste bovine. Dans le cadre de l'amélioration de la stratégie de prophylaxie, un programme de surveillance épidémiologique a été mis en œuvre par le projet PARC.

Péripneumonie contagieuse bovine La diffusion de la péripneumonie contagieuse bovine étant fortement liée aux mouvements du bétail transhumant, la maladie a connu une flambée dans le nord du département du Zou avec l'afflux de transhumants refoulés d'un pays voisin. L'aire de distribution de la maladie s'élargit au département du Mono. 4. Maladie de Newcastle La maladie de Newcastle est endémique sur tout le territoire, et sa morbidité demeure sensiblement la même d'une année à l'autre. Six foyers ont été signalés : les départements du Mono et de l'Ouémé, et, dans le Borgou. les sous-préfectures de Malanville, Kandi, Bembèrèkè, Parakou et Tchaourou. II.

El financiamiento del Programa se encuentra en fase de negociación. B O T S W A N A INTRODUCTION The major event in epidemic disease control was that Botswana was re-invaded by contagious bovine pleuropneumonia (CBPP) after 56 years of freedom from the disease, In early February clinical disease suspected to be CBPP in cattle in Ngamiland district in the far north-west of the country was confirmed by the laboratory. Control measures, based on a stamping-out policy and involving the destruction of 24,000 cattle are discussed in I, 2 below Control of other diseases continued and annual vaccination programmes were carried out as planned despite difficulties arising from the need to allocate considerable resources to CBPP control. Experience in the general control of animal diseases was good. All significant disease incidents reported are discussed below. The Department of Animal Health and Production notes with great regret the loss of Dr Tsholofelo Diteko, who served as Director of Veterinary Services from January 1993 to January Î995. This resulted in major staff changes at the senior level in the Department Dr Motshudi Raborokgwe was appointed Director of the Department and Dr Kereng Masupu was appointed his deputy.

Protection of this status requires rigorous imposition of quarantines, maintenance of the buffalo and cordon fences and bi- and tn-annual vaccination of cattle in high risk areas using trivalent SAT 1, 2 and 3 vaccine. During the year, 349,360 cattle were vaccinated. 1939 06-94 1994 12-94 1994 -58- 2 Contagious bovine pleuropneumonia The beginning of 1995 saw confirmation of contagious bovine pleuropneumonia at Xaudum Valley in Ngamiland district. The first five confirmed cases were recorded in February and altogether 181 cases were confirmed in the district. Movement control, quarantine measures, and testing and slaughter have been implemented. Infected and exposed herds were depopulated in the control area. The area itself has been delineated by two 140-km long cordon fences running in an east-west direction to facilitate movement control measures. Veterinary officials were placed at strategic points to enforce control and testing of all animals required. Altogether 23,782 cattle were slaughtered and destroyed by burning from March to December 1995. A compensation scheme and other assistance have been introduced. The disease continues to be closely monitored through a large-scale surveillance programme, with regular testing of ear-tagged animals within the control zone north of 20° S, with the objective of eliminating positive herds. The National Veterinary Laboratory can examine over 3,000 sera per week with the complement fixation test. 3 Lumpy skin disease Following the implementation of free lumpy skin disease vaccination country-wide towards the end of 1994 and at the beginning of 1995, the disease was brought under control and no case was confirmed in 1995 4 Bluetongue In February, 52 bovine sera from Orapa (Central district) were confirmed to have bluetongue virus antibodies by the agar-gel immunodiffusion test. The animals showed clinical signs of lameness and excoriations in the mouth. Differential serological diagnosis for foot and mouth disease was negative. It is interesting that bluetongue seropositive goats have also been detected in the same area. 5. .African horse sickness There was an apparent 6 0 % reduction in the number of African horse sickness confirmed cases in 1995. This is probably due to decreased surveillance rather than to an actual reduction of African horse sickness incidence in Botswana. Two suspected clinical cases in Maun district in May were confirmed to be positive with high antibody titres for African horse sickness. 6 Newcastle disease Newcastle disease was recorded in February from Mochudi and Gaborone districts with one case each. Confirmation was by virus isolation from vanous tissues. Two more cases were confirmed in April from Francistown and Molepolole districts. Cases were confirmed in flocks from Maun in June and September. On two occasions in October the disease was confirmed in flocks from Mogoditshane in Gaborone district. The incidence of this disease has not increased much from 1994 and it is important to mention that it continues to be confined to backyard chicken flocks with less than 100 birds. Control is by voluntary chick vaccination using La Sota and Hitchner strains.

The control is by compulsory, free vaccination of all cattle. 2. Echinococcosis-hvdatidosis This disease is mainly seen during carcase examination at the three export abattoirs of Francistown, Maun and Lobatse. Municipal abattoirs also reported the condition but no reliable data are available from them. Lungs and livers were the main organs affected at Maun and Francistown abattoirs while at Lobatse spleen cases were reported. Francistown reported 3,829 positive out of 45,462 slaughtered (8%), Maun 661 out of 19,011 (14%) and Lobatse 6,542 out of 105,910 (6%). 3 Heartwater In cattle Heartwater is considered to cause greater losses than any other tick-borne disease in Botswana. It is reported throughout the year in the eastern hard veldt. A total of 20 cases were confirmed positive for heartwater: 8 cases from Kanye district, 4 from Gaborone district; Mochudi, Palapye and S/Phikwe had 2 each and Jwaneng and Mahalapye 1 each. Cases occurred in all months except August. In sheep and goats A total of 39 cases, mostly in goats, were reported from many districts: Francistown, Gaborone. Kanye. Lobatse, Mahalapye, Molepolole, Serowe, Orapa and S/Phikwe. Cases occurred in all months of the year except February and May. 4. Rabies In 1995, material from 377 suspected rabies cases were examined with the fluorescent antibody test (FAT), of which 311 (82%) were confirmed positive and 65 (21%) negative. There were further rabies notifications where specimens were not submitted. The majority of submissions and confirmed positive cases (59%) came from the southern region with Jwaneng district contributing about one quarter of these. The northern region contributed 127 (41%) confirmed cases from its 156 submissions. Selebi/Phikwe district had the lowest confirmed case load.

The 26 cases in wild mammals were mostly canids, represented by 21 jackals (Cams mesomelas), 3 hyenas (Crocuta crocuta), 1 wild dog (Lycaon pictus) and 1 bat-eared fox (Otocyon megatotis). There was 1 case in honey badger (Mellivora capensis), 3 in mongoose (Viverridae), and 1 in a squirrel. There were 14 cases in felids: 5 wild cats, 8 genet cats (Genetta grimmia) and 1 cheetah (Acinonyx jubatus). Compulsory annual vaccinations of domestic dogs and cats is still the control strategy for rabies. Rabies notifications These are suspected cases with no specimens sent for examinations. This year, 47 of such cases were regarded positive for rabies, 24 (51%) of which came from the southern districts and the other 23 (49%) from nothern districts.

Bovine babesiosis Bovine babesiosis is diagnosed sporadically and in 1995 was diagnosed only once, in Molepolole. 2. Bovine brucellosis There was no laboratory isolation of Brucella abortus in 1995 but clinical disease was diagnosed in herds in Kanye, Letlhakane, Molepolole. Mahalapye and Serowe. Two dairy herds from Kanye in the south became positive on bulk milk screening in January. In February there were 2 cases from Gaborone, 2 from Mahalapye, 1 from Orapa and 2 from Serowe. Bulk milk samples from Molepolole tested positive in October. 3. Bovine pasteurellosis (haemorrhagic septicaemia) Five districts each recorded one case of bovine pasteurellosis as follows: in January in Maun, in February in Kanye, in March in Serowe, in May in Maun and in June in Mahalapye. Diagnosis was based on clinical signs and isolation of Pasteurella multocida (P. multocida from tissues submitted for examination from a sheep at Kanye district in July). 4. was isolated Theileriosis Theileriosis presents in combination with other infestation or bacterial infections. The significance of Theileria sp. in blood smears is not yet clear. Serowe registered the highest number of cases with 6 (21%) out of a total of 28 confirmed cases. Mochudi followed with 5 (18%), then Francistown and Palapye with 4 (14%) each. Mahalapye registered 3 (11%), followed by Gaborone and Kanye with 2 (7%) each. Orapa and S/Phikwe had 1 (4%) case each.

E n este sentido, y en base al estudio de los intercambios de bovinos, se establecieron en el país cinco grandes "circuitos pecuarios", buscándose así una mejor adecuación de las estrategias previstas para la erradicación de la enfermedad. - Circuito Pecuario del Sur: comprende los Estados de Río Grande do Sul, Santa Catarina y la región sureña del Estado del Paraná. - Circuito Pecuario del Centro-Oeste: abarca los Estados de Mato Grosso do Sul, Mato Grosso. Goiás, Sao Paulo, parte del territorio del Estado de Minas Gérais (regiones del Triángulo Mineiro, Alto Paranaíba, Chapadâo do Paracatu, Sul de Minas, Alto Sao Francisco y Centro-Oeste), la región norteña del Estado del Paraná, parte del territorio del Estado de Tocantins (regiones de Gurupi, Paraíso, y parcialmente las regiones de Porto Nacional y Miracema do Tocantins) y el Distrito Federal. - Circuito Pecuario del Este: formado por los Estados de Río de Janeiro, Espirito Santo, Bahía y las regiones de Minas Gérais no incluidas en el Circuito Pecuario del Centro-Oeste. - Circuito Pecuario del Nordeste: comprende los Estados de Sergipe, Alagoas, Pernambuco, Paraíba, Río Grande do Norte, Ceará, Piauí y Maranhào. - Circuito Pecuario del Norte: formado por los Estados de Acre, Amazonas, Rondônia, Amapá, Roraima, Para y las regiones del Estado de Tocantins no incluidas en el Circuito Pecuario del CentroOeste. -63- En 1995 se notificaron 666 focos de enfermedades vesiculares (589 focos de fiebre añosa), observándose una reducción notable con relación a los años 1992 (1.232 focos), 1993 (1.432 focos) y 1994 (2.093 focos), respectivamente del 45,95%, 53,50% y 68,18%. En todos los Circuitos Pecuarios, excepto el del Este, el número de focos ha decrecido. Los meses de mayor ocurrencia fueron marzo, abril y m a y o , que representaron el 50.91% del total anual de focos. No hubo notificación de enfermedades vesiculares en los Estados de Río Grande do Sui, Santa Catarina, Mato Grosso do Sul, Alagoas, Paraíba y A m a z o n a s ni en el Distrito Federal. Se recolectaron muestras para el diagnóstico íaboratonal en 273 focos de los 666 focos registrados durante el periodo (el 41,00%). De estos 273 focos f u e r o n confirmados laboratoriaímente 198, o sea el 72,53% de los rebaños muestreados. Se nota un aumento de la recolección de muestras en comparación con 1994 (correspondía entonces al 35,50% de los focos registrados). El virus de tipo A fue el más frecuente, con 99 diagnósticos positivos, seguido por el tipo O (83 diagnósticos positivos) y el C (3 diagnósticos positivos). Hubo 13 diagnósticos de estomatitis vesicular (virus Indiana): 12 en el Estado de Minas Gérais (Circuito Pecuario del Este) y 1 en el Estado de Mato Grosso (Circuito Pecuario del Centro-Oeste). En 64 focos el diagnostico Íaboratonal fue negativo para la fiebre aftosa y la estomatitis vesicular, sin poder establecer un diagnóstico diferencial. Por lo tanto, de los 666 focos de enfermedades vesiculares notificados durante el período. 589 se refieren a fiebre aftosa y 13 a estomatitis vesicular En l o s años 1994 y 1995 se observaron las siguientes tasas en el país: 1994 1995 Morbilidad (por 10.000) 5,08 1,41 Mortalidad (por 100.000) 0,90 0,23 Letalidad (por 1.000) 17,61 16,04 Tasa de ataque (por 100) 18.52- 18,19 Circuito Pecuario del Sur La última ocurrencia de fiebre aftosa en este Circuito Pecuario fue en el Estado del Paraná en abril de 1994. Los Estados de Río Grande do Sul y Santa Catarina completaron en diciembre de 1995 dos años sin casos clínicos de enfermedades vesiculares. En estos dos Estados, está en proceso de elaboración una encuesta seroepidemiológica para la búsqueda de actividad viral. Se pretende obtener el reconocimiento ante la OIE, de la condición de "zona libre de fiebre aftosa con vacunación" para estos dos Estados, considerando el Paraná como "zona tampón". Circuito Pecuario del Centro-Oeste Durante el año 1995 se notificaron en este Circuito 191 focos de enfermedades vesiculares (171 focos de fiebre aftosa), observándose una reducción del 72,76% en comparación con el año 1994, cuando se registraron 701 focos. Hubo recolección de muestras en 111 focos (58,12%), siendo confirmados laboratoriaímente 91 focos, o sea el 81.99% de los rebaños donde hubo recolección. El virus O fue el más frecuente, con 58 diagnósticos, seguido por el A con 31, el C con 1 diagnóstico y estomatitis vesicular tipo Indiana, también con 1 diagnóstico. De los 191 focos, 19 tuvieron diagnóstico laboratorial negativo para la fiebre aftosa y la estomatitis vesicular. Por lo tanto, en este Circuito ocurrieron 171 focos de fiebre aftosa y 1 de estomatitis vesicular. En todos los focos ocurridos en el Estado del Paraná todos los bovinos y suinos fueron sacrificados. -64- Circuito Pecuario del Este Durante el año 1995 se notificaron 212 focos de enfermedades vesiculares (165 focos de fiebre aftosa), número ligeramente superior a los 205 focos registrados en 1994. Este aumento fue debido básicamente al aumento de las notificaciones registradas en los Estados de Espirito Santo (52 focos en 1995 y 11 en 1994). Babia (62 focos en 1995 y 27 en 1994) y Rio de Janeiro (44 focos en 1995 y 32 focos en 1994). En las regiones del Estado de Minas Gérais pertenecentes a este Circuito, se señalaron 54 focos, observándose una reducción del 6 0 % en comparación con los 135 que se notificaron durante el mismo período del año anterior. De los 54 focos, 12 tuvieron diagnóstico laboratonal para estomatitis vesicular tipo Indiana. Hubo recolección de muestras en 123 focos (58,02%), siendo confirmados íaboratoríalmente 88, o sea el 71,55% de los rebaños mostreados. Eí virus A fue el más frecuente, con 64 diagnósticos, seguidos por el tipo O con 12, y hubo también 12 diagnósticos de estomatitis vesicular tipo Indiana (Minas Gérais). De los 212 focos, 35 tuvieron diagnóstico laboratonal negativo para la fiebre aftosa y estomatitis vesicular. Por lo tanto en este Circuito se puede afirmar que ocurrieron 165 focos de fiebre aftosa y 12 de estomatitis vesicular. Circuuo Pecuario del Nordeste Durante el año 1995 se notificaron 185 focos de enfermedades vesiculares (176 focos de fiebre aftosa), lo que representa una reducción notable de 81,07% en comparación con el mismo período del año anterior (977 focos en 1994). Hubo recolección de muestras en 22 focos (11,90%), de los que se confirmaron Íaboratoríalmente 10 focos, o sea el 45,45% de los rebaños muestreados El virus O fue el más frecuente (6 diagnósticos), seguido por el tipo A (4 diagnósticos). De los 185 focos, 9 tuvieron diagnóstico laboratorial negativo para la fiebre aftosa y la estomatitis vesicular. Por lo tanto, los P 6 focos confirmados en este Circuito se refieren a fiebre aftosa. Circuito Pecuario del Norte Durante el año 1995 se notificaron 78 focos de enfermedades vesiculares (76 focos de fiebre aftosa), lo que representa una reducción de 53.58% en comparación con ios 168 focos de 1994. Se recolectaron muestras en 17 focos (21,80%), de los cuales 9 fueron confirmados Íaboratoríalmente, o sea el 52,95% de los rebaños mostreados. El virus O fue el más frecuente (7 diagnósticos), seguido por el tipo C (2 diagnósticos). De los 78 focos, 4 tuvieron diagnóstico laboratonal negativo tanto para ía fiebre aftosa como para la estomatitis vesicular. Por lo tanto, en este Circuito se presentaron 76 focos de fiebre aftosa. Vacunas contra ¡afiebre aftosa En 1995 se produjo 176.971.860 dosis de vacuna contra la fiebre aftosa: 158.343.510 dosis con adyuvante oleoso (89.48%) y 18.628.350 dosis hidróxido-saponinadas (10,52%). Las cepas utilizadas son: A Cruzeiro, O, Campos y C adyuvante acuoso (hidróxido-saponinadas). 2 4 3 Indaial en fórmulas con adyuvante oleoso y Los métodos de control utilizados fueron: - vacunas con adyuvante oleoso: prueba ELISA - vacunas hidróxido-saponinadas: PGP Fue aprobado en las pruebas oficiales de control el 95,69% de las vacunas producidas: el 100% de las hidróxido-saponinadas y el 95.19% de las oleosas (150.714.180 dosis). No hubo importación de vacunas. En cambio, fueron exportadas 3.742.500 dosis de vacunas (3.487.500 dosis de vacuna oleosa bivalente y 255.000 dosis de vacuna oleosa trivalente). -65- Vacunación contra la fiebre aftosa En 1995 se vacunaron 107.243.498 bovinos contra la fiebre aftosa. Durante el mismo periodo fueron sometidos a vacunaciones estratégicas 251.000 bovinos. Se observó un aumento de 5.94% del número de bovinos vacunados en comparación con el año 1994 (101.238.001 bovinos vacunados en 1994). Las vacunaciones fueron realizadas en su mayor pane por el productor, bajo la supervisión del servicio oficial, y en algunas unidades federativas por vacunadores acreditados u oficiales, en el marco de un programa de vacunación semestral, algunas unidades habiendo adoptado ya el programa anual para bovinos de más de dos años. Las vacunaciones estratégicas son realizadas en regiones específicas, fronteras internacionales y áreas perifocales. 2 Peste porcina clásica La producción de vacunas contra esta enfermedad fue de 12.076.660 dosis. 3. Enfermedad de Newcastle El Programa Nacional de Sanidad Avícola, que tiene como objetivo eí control de la enfermedad de Newcastle, de la micoplasmosis y de la salmonelosis aviar, comprende la regionalización sanitana basada en los diferentes niveles de desarrollo del sector avícola. El Programa empezó por los Estados de Río Grande do Sul, Santa Catarina, Paraná, Sao Paulo, Minas Gérais, Mato Grosso y Mato Grosso do Sul. La colaboración entre los sectores público y privado ha sido establecida a través de la creación de un Comité Nacional y de Comités Estatales de Sanidad Avicola.

Depuis, la maladie s'est progressivement étendue à l'ensemble du pays. En 1992, on 12-94 12-94 12-94 12-94 10-94 11-94 -68- a pu identifier le virus SAT 2 et en 1994 le virus A. En 1995, on a dénombré 2 545 malades et 45 morts, surtout des veaux. Au début de 1996, des foyers étaient encore signalés dans certaines provinces du pays : provinces du Kénédougou, de la Comoé, du Bulkiemdé, du Séno. 2. Peste bovine En 1995, 1 117 320 bovins ont été vaccinés contre cette maladie. Cependant, il est prévu d'arrêter très prochainement les vaccinations et de mettre en place un système d'alerte précoce qui permettra de circonscrire rapidement les éventuels foyers de cette maladie qui pourraient réapparaître. 3. Peste des petits ruminants En 1995, des foyers de cette affection ont été suspectés dans trois provinces du nord du pays (provinces du Sourou, du Soum et du Yatenga). Cependant, aucune confirmation n'a pu être faite. La vaccination contre la maladie à partir du vaccin hétérologue est effectuée dans ces trois provinces. 4. Pénpneumonie contagieuse bovine Localisée surtout dans l'ouest du pays, on a noté en 1995 une recrudescence de cette maladie à partir des foyers anciens, le long de la frontière à l'ouest du pays. La péripneumonie contagieuse bovine fait l'objet d'un programme national de lutte, et 418 178 bovins ont été vaccinés en 1995. 5. Dermatose nodulaire contagieuse Deux foyers ont été signalés en 1995 (un dans le Boulgou, l'autre dans le Houet). 6 Clavelée et variole caprine Un seul foyer de clavelée a été signalé en 1995. dans l'Oudalan. 7. Maladie de Newcastle La maladie de Newcastle sévit de façon enzootique au Burkina Faso et chaque année un programme de vaccination est mis en place pour lutter contre cette affection. IL MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Fièvre charbonneuse Elle sévit sous forme enzootique dans certaines provinces du pays et frappe surtout les bovins, mais aussi les petits ruminants, les suidés, et, très rarement, les asins. En 1995, 22 foyers au total (10 chez les bovins, 10 chez les petits ruminants, 1 chez les porcins et 1 chez les asins) ont été signalés. La vaccination s'effectue dans les zones à risque. 2. Cowdnose Elle est suspectée au Burkina, mais aucune confirmation n'a été faite jusqu'à présent en laboratoire. 3. Rage La rage canine sévit de façon enzootique et plusieurs cas sont signalés annuellement. -69- Maladies des bovins 4. Brucellose bovine Des tests sérologiques effectués sur certains troupeaux ont donné des résultats positifs et dans certaines provinces des cas de la maladie ont été signalés, se manifestant surtout par un hygroma du genou. 5. Tuberculose bovine Elle sévit de façon enzootique dans le pays, mais les cas constatés proviennent surtout des saisies d'abattoir. 6. Septicémie hémorragique La maladie existe au Burkina Faso de façon enzootique. En 1995, 40 foyers ont été signalés, qui ont fait 1 187 cas et 227 morts. Une campagne de vaccination est organisée annuellement contre cette affection dans les provinces où la maladie sévit le plus. En 1995, 269 969 bovins ont été vaccinés. 7. Trypanosomose Les trypanosomoses animales africaines sévissent de façon enzootique dans le sud et l'ouest du pays, dans les provinces où sont les glossines. Dans ces provinces, on lutte contre la maladie par la chimioprévention et la lutte antivectorielle. En 1995, 125 998 bovins ont ainsi été prémunis. IIÏ. AUTRES MALADIES 1. Charbon symptomatique La maladie sévit régulièrement dans certaines provinces du pays. Au cours de l'année 1995, il y a eu au total 77 foyers ayant entraîné 5 852 cas et 473 morts. La vaccination se fait dans les zones à risque. 2. Pasteurellose des petits ruminants Elle est très suspectée dans certaines provinces du pays. En 1995, 18 foyers ont été suspectés, ayant fait 867 malades et 159 morts. La vaccination est effectuée dans les provinces à risque. -70- C A M E R O U N INTRODUCTION Changement dans les structures technico-administratives : dissolution de l'Office pharmaceutique vétérinaire. Privatisation de la profession vétérinaire : on note une entrée en force des praticiens privés pour les soins aux animaux et la distribution des médicaments vétérinaires. Les praticiens privés sont actuellement 35. Un texte sur le mandat sanitaire est en préparation. Situation zoo-sanitaire : la situation zoo-sanitaire est restée globalement satisfaisante mais toujours précaire à cause des menaces aux frontières et des moyens de lutte disponibles limités. I.

Reorganising the Federal food inspection system The Government of Canada is consolidating all federally-mandated food inspection and quarantine services into a single federal food inspection agency. This agency will be established in early 1997 and report to Parliament through the Minister of Agriculture & Agri-Food Canada. The consolidation into a single agency will enhance food safety systems by integrating the delivery of inspection and quarantine services currently provided by Agriculture and Agri-Food Canada, Health Canada, and Fisheries and Oceans Canada. All inspection services related to food safety, economic fraud, trade-related requirements, and animal and plant health programs, will be provided by the new agency. The responsibility for food safety policy, standard-setting, risk assessment, analytical testing research and audit will be reinforced and remain with Health Canada. The reorganization will reduce costs, enhance efficiency, and improve the effectiveness of inspection and quarantine services. These activities currently cost over CAD 400 million and involve over 5.000 people in three federal departments. All those involved in the production of food, or in the import or export of food, live animals or plants, will be able to deal with a single agency for inspection and quarantine services. Canadians have one of the best, food inspection systems in the world. As high-quality food supply - this will not be compromised. By using the same for all foods in an integrated federal food inspection system, food safety consumers will be able to address food inspection questions or concerns to a dealing with three separate departments a result, consumers enjoy a safe standards and inspection systems will be enhanced. Furthermore, single federal contact rather than Canadian companies will continue to have access to international markets and to have the competitive edge necessary to capture additional trade opportunities. An integrated federal food inspection system will allow Canadian exporters to better respond to the changing demands of the international marketplace. With the creation of the agency, importers of several different types of food products will be able to deal with one federal organization for issues related to import inspection. I. LIST A DISEASES Domestic animals in Canada remained free from all List A diseases.

LIST B DISEASES Reportable diseases The following List B diseases are prescribed as reportable in Canada: anthrax, Aujeszky's disease, rabies, anaplasmosis, bovine brucellosis (B. abortus), bovine tuberculosis, cysticercosis (C. bovis), bovine spongiform encephalopathy., caprine and ovine brucellosis (B. melitensis), scrapie, sheep mange (Psoroptes ovis), contagious equine metritis, dourine, equine infectious anemia, equine piroplasmosis (babesiosis), glanders, horse mange, porcine brucellosis (B. suis), trichinellosis, fowl typhoid, pullorum disease and varroasis. Many of these diseases have either never been reported in Canada, or have been eradicated. The following reportable List B diseases were the focus of disease control activities in 1995: Diseases of multiple 1. species Rabies During 1995, 469 positive cases of rabies were reported in domestic and wild animals. This represents less than half of the positive isolations recorded in 1994. Rabies in the red fox and the striped skunk represented the majority of the wild animal cases, however, rabies was also reported in bats, one raccoon, one coyote, and two wolves. Bait vaccination of foxes continued in the eastern p a n of the province of Ontario. Diseases of cattle 2 Bovine brucellosis Canada was declared free of bovine brucellosis in 1985. No cases of bovine brucellosis have been identified since an atypical biovar 5 B. abortus was isolated from a strain 19 vaccinated beef cow in 1989. Surveillance for brucellosis continued in 1995 with approximately 400,000 serological tests performed on market and slaughter cows and bulls and on animals for export and entry into artificial insemination centres. All dairy herds are subject to quanerly milk ring testing. 3. Bovine tuberculosis No outbreaks of bovine tuberculosis have been identified in Canadian cattle herds since 1991 although in 1992 there was slaughter of cattle as a result of exposure to outbreaks in 1991. Surveillance for tuberculosis in 1995 included the submission of suspect granulomatous lesions from cattle at slaughter for laboratory confirmation, and approximately 400,000 tuberculin tests conducted primarily for export purposes. 4. Bovine cysticercosis Bovine cysticercosis has only an exceptional occurrence in Canada. During 1995, 99 positive carcases were detected at abattoirs, from 12 premises. Of these, 53 animals were from three positive premises. This number of cases represents about 0.004% of the approximately 2.5 million cattle slaughtered and inspected annually. Resident cattle in infected herds undergo controlled removal, slaughter, and carcass treatment. Diseases of sheep and goats 5. Scrapie There were 8 cases of scrapie diagnosed in 1995, 3 in Quebec and 5 in Ontario, from 5 sheep flocks. Three flocks were depopulated. A total of 23 laboratory submissions were made in 1995. The total number of animals ordered slaughtered in Ontario was 206 and 694 in Quebec. -74- Diseases of horses 6. Equine infectious anaemia During 1995, 135 cases of equine infectious anemia (EIA) were detected. Owners of positive animals had an option to slaughter (without compensation) or use permanent isolation. Approximately 62,972 serological tests for EIA were performed for routine domestic and international movement to the USA. Diseases of pigs 7. Trichinellosis No cases of trichinellosis were detected in 1995. With the exception of one incident, in 1994, involving the illegal feeding of edible waste, Canada has been free of the parasite in its swine population since 1983. At slaughter approximately 30,000 randomly selected swine, and all horses, approximately 70,000, and about 250 wild boars were tested and found negative using trichinoscopic and/or digestive techniques. Diseases of poultry 8. Pullorum disease {Salmonella pullorum) No cases of pullorum disease were detected during 1995. The disease has not been detected since 1989. Surveillance methods include the testing of breeding and hatchery supply flocks, the culturing of fluff samples from hatcheries, birds for export, imponed birds, and the testing of exhibition and game birds. Non-reportable diseases Non-reportable List B diseases, which have not been known to occur in Canada include: heartwater, screwworm, babesiosis of cattle, theileriasis, trypanosomiasis, contagious caprine pleuropneumonia, Nairobi sheep disease, epizootic lymphangitis of horses, horse pox, Japanese encephalitis of horses, surra, Venezuelan equine encephalomyelitis, myxomatosis, viral haemorrhagic disease of rabbits and leishmaniasis. Disease of Fish The North American strain of viral haemorrhagic septicaemia (VHS) was isolated from Atlantic salmon (Salmo salar) farmed in British Columbia in March 1995. This apparently represents the first time that the North Amencan strain of VHS has been isolated from farmed Atlantic salmon. -75- C A N A D A INTRODUCTION L'état sanitaire des bovins et des volailles au Canada demeure essentiellement inchangé depuis le rapport de 1994. La restructuration du système fédéral d'inspection des aliments Le gouvernement canadien regroupera tous les services d'inspection des aliments et de protection sanitaire et phytosanitaire (SPS) relevant de lui en une agence fédérale unique d'inspection des aliments. L'agence sera créée au début de 1997 et rendra des comptes au Parlement par l'entremise du ministre de l'Agriculture et de LAgroalimentaire du Canada. Cette fusion améliorera les systèmes de salubrité des aliments en intégrant les services d'inspection et de protection SPS que dispensent actuellement Agriculture et Agroalimentaire Canada, Santé Canada et Pêches et Océans Canada. Ce sera par ailleurs la nouvelle agence qui s'occupera des inspections liées à la salubrité des aliments, de la lutte contre les fraudes économiques, des exigences à caractère commercial ainsi que des programmes de protection SPS. Santé Canada maintiendra et renforcera son rôle en ce qui concerne la politique de salubrité des aliments, l'établissement des nonnes, l'évaluation des risques, la recherche sur les analyses ainsi que la vérification. La réorganisation réduira les coûts et améliorera le rendement et l'efficacité des services d'inspection et de protection SPS. Ces activités coûtent actuellement plus de 400 millions de CAD et mobilisent plus de 5 000 fonctionnaires dans trois ministères fédéraux. Toutes les entreprises qui produisent des denrées alimentaires ou qui importent ou exportent des aliments, des animaux ou des végétaux pourront obtenir de l'agence unique des services d'inspection et de protection SPS. Les Canadiens jouissent de l'un des meilleurs systèmes d'inspection'des aliments au monde. Pour leur part, les consommateurs bénéficient d'un approvisionnement en aliments sains et de qualité élevée ; rien ne viendra compromettre ces acquis. La mise en place d'un système fédéral intégré d'inspection permettra d'améliorer la salubrité des aliments, car ce seront les mêmes normes et systèmes d'inspection qui prévaudront pour la totalité des aliments. De plus, les consommateurs pourront transmettre leurs questions sur l'inspection des aliments à un seul point de contact fédéral au lieu de communiquer avec trois ministères distincts. Les entreprises canadiennes conserveront leur accès aux marchés internationaux et elles seront suffisamment compétitives pour conquérir d'autres débouchés. La création d'un système fédéral intégré d'inspection des aliments permettra aux exportateurs de mieux répondre à l'évolution des besoins du marché international. La création d'une agence permettra aux importateurs de plusieurs types de produits alimentaires de communiquer avec un seul organisme fédéral pour obtenir des renseignements sur l'inspection des importations.

Bon nombre de ces maladies n'ont jamais été signalées au Canada ou en ont été éradiquées. Les maladies à déclaration obligatoire suivantes, énumérées sur la liste B, ont été la cible de mesures zoosanitaires en 1995 : Maladies communes à plusieurs espèces Rage En 1995, on a signalé 469 cas positifs de rage chez des animaux domestiques et sauvages, soit moins de la moitié des cas confirmés en 1994. Chez les animaux sauvages, la maladie affecte surtout les renards roux et les mouffettes ; cependant, on en a signalé quelques cas chez les chauves-souris, un raton laveur, un coyote, et deux loups. La vaccination des renards au moyen d'appâts s'est poursuivie dans l'est de l'Ontario. Maladies des bovins 2. Brucellose bovine Le Canada a été déclaré exempt de brucellose bovine en 1985. Aucun cas de cette maladie n'a été dépisté depuis l'isolement d'un biovar 5 atypique de B. abortus chez une vache de boucherie vaccinée avec la souche 19 en 1989. Les autorités ont poursuivi la surveillance en 1995 en procédant à près de 400 000 épreuves sérologiques sur des vaches et des taureaux de marché et d'abattage et des animaux pour l'exportation et l'entrée dans un centre d'insémination artificielle. Tous les trimestres, tous les troupeaux laitiers doivent subir l'épreuve de l'anneau. 3. Tuberculose bovine Aucun foyer de tuberculose bovine ne s'est manifesté chez les bovins canadiens depuis 1991, bien qu'en 1992, on ait abattu des sujets exposés à la maladie en 1991. En 1995, la surveillance incluait, d'une part, la présentation de spécimens de lésions granulomateuses suspectes prélevées chez des bovins à l'abattoir aux fins de confirmation en laboratoire et, d'autre part, la conduite d'environ 400 000 épreuves à la tuberculine surtout aux fins d'exportation. La recherche se poursuit en vue de mettre au point d'autres épreuves de dépistage de la tuberculose chez les bovins et les cervidés. 4. Cysticercose bovine La fréquence de la cysticercose au Canada n'est qu'exceptionnelle. En 1995, on a dépisté 99 carcasses infectées, provenant de 12 fermes. Cinquante-trois des bêtes atteintes provenaient de trois établissements en particulier. Ce taux de prévalence à l'abattoir correspond à 0,004 % sur près de 2,5 millions de bovins -77- abattus et inspectés chaque année. Les bovins faisant partie de troupeaux infectés en sont retirés et abattus sous surveillance, et la carcasse est traitée. Maladies des ovins et caprins 5. Tremblante On a diagnostiqué 8 cas de tremblante en 1995, 3 au Québec et 5 en Ontario, provenant de 5 troupeaux d'ovins. On a abattu 3 troupeaux entiers d'ovins. Cette année là, le laboratoire a reçu 23 spécimens pour fin d'analyse. En Ontario, 206 moutons ont dû être abattus de même que 694 au Québec. Maladies des équidés 6. Anémie infectieuse des équidés En 1995, on a diagnostiqué 135 cas d'anémie infectieuse des équidés (AIE). Les propriétaires des animaux déclarés positifs pouvaient soit faire abattre leurs sujets (sans indemnisation), soit les isoler en permanence. Environ 62 972 épreuves sérologiques de dépistage de l'AEE ont été menées régulièrement aux fins du commerce intérieur et des échanges bilatéraux avec les États-Unis. Maladies des porcins 7. Tnchinellose Aucun cas de tnchinellose n'a été détecte en 1995. A l'exception d'un incident, en 1994, à cause de l'alimentation illégale de déchets, le Canada est exempt du parasite chez les porcs depuis 1983. Lors d'épreuves de dépistage aux abattoirs utilisant les techniques trichinoscopiques et/ou digestives, plus de 30 000 porcs choisis au hasard, tous les chevaux (plus de 70 000) et environ 250 sangliers sauvages ont eu des résultats négatifs. Maladies des 8. volailles Pullorose (Salmonella pullorum) On n'a décelé aucun cas de cette maladie en 1995. En fait, aucun foyer n'a été signalé depuis 1989. Les méthodes de surveillance comprennent la conduite d'épreuves des troupeaux de reproduction et d'approvisionnement des couvoirs, la culture d'échantillons de duvet provenant des couvoirs, des oiseaux destinés à l'exportation et importés, ainsi que les épreuves menées aux expositions et sur le gibier à plumes. Maladies non declarables Les maladies non declarables suivantes de la liste B n'ont pas été signalées au Canada : cowdriose, myiase, babésiose bovine, theilériose, trypanosomose, pleuropneumonie contagieuse caprine, maladie de Nairobi, lymphangite épizootique des équidés, variole équine, encéphalite japonaise, surra, encéphalomyélite équine vénézuélienne, myxomatose, maladie hémorragique virale du lapin et leishmaniose. Maladies des poissons La souche de l'Amérique du Nord de la septicémie virale hémorragique (SVH) a été isolée chez le saumon d'élevage de l'Atlantique (Salmo salar) en Colombie-Britannique en mars 1995. C'est la première fois que cette souche de SVH est isolée chez le saumon d'élevage. -78- C O L O M B I A I.

Enfermedad de Newcastle Se comprobó la presencia de la enfermedad de Newcastle, cepa velogénica, en explotaciones de los departamentos de Cundinamarca y Meta. II. ENFERMEDADES DE LA LISTA B 1. Prurigo lumbar Colombia se considera libre de esta enfermedad siendo confirmada en el año 1976 en un lote de reproductores ovinos de la raza Cheviot, durante cuarentena de importación, su procedencia fue el Reino Unido. La totalidad del lote se erradicó por sacrificio sanitario y eliminación del animal enfermo y sus contactos. No se ha vuelto a notificar esta enfermedad en el país. 2. Encefalomielitis equina venezolana Se presentó una epizootia de encefalomielitis equina venezolana en el departamento de La Guajira entre septiembre y octubre de 1995, que causó mortalidad en equinos y humanos (véase Boletín de la OIE, vol. 107, n ° 2 , págs. 131-132). 12-94 12-94 12-94 12-94 01-94 09-94 09-94 -79- C Ô T E D ' I V O I R E INTRODUCTION L'Etat ivoirien a opté pour une politique de désengagement de certaines activités vétérinaires suite à la restructuration des services agricoles. Un nouveau dispositif d'exécution et de financement des programmes de santé animale et de promotion d'un secteur vétérinaire privé a été mis en place. Le suivi de la situation zoo-sanitaire a connu des modifications au niveau du terrain. En 1995, les vaccinations obligatoires contre íes maladies contagieuses du bétail ont été exécutées par les agents des Services extérieurs du ministère de l'agriculture et des ressources animales et les mandataires privés à Abidjan, Odienné et Ferké. Selon les régions, les Services extérieurs ont été appuyés par les encadreurs deflates de l'ex-Société pour le développement des productions animales (SODEPRA) ou les conseillers agricoles de l'Agence nationale d'appui au développement rural (ANADER), spécialisés en santé animale. Ces agents travaillent sous la supervision d'un médecin vétérinaire. Le recouvrement des coûts a été institué sur toute l'étendue du territoire. La contribution des éleveurs est fixée à 50 francs CFA. La surveillance des foyers de maladies contagieuses a été effectuée par les Services extérieurs en collaboration étroite avec le Laboratoire national d'appui au développement agricole (LANADA), à travers ses trois laboratoires régionaux de pathologie animale de Korhogo, Bouaké et Bingerville.

Après l'analyse des prélèvements effectués sur les bovins de la région Centre, les résultats ont mis en évidence la présence des types O et A. C'est la première fois que le type O est identifié en Côte d'Ivoire. Le type A existe en Côte d'Ivoire depuis 1971. L'origine de ces nouveaux sérovars reste pour le moment inconnue. 2. Peste bovine Au cours de l'année 1995, 424 305 bovins ont été vaccinés contre la peste bovine, soit 35 % de l'effectif estimé. Le contrôle de l'immunité post-vaccinale (sérosurveillance) est prévu pour les mois de mars et avril 1996. 3. Peste des petits ruminants Au total, 61 163 petits ruminants ont été vaccinés, dont 53 839 ovins et 7 324 caprins, au cours de la campagne de prophylaxie 1995. Cette faiblesse des chiffres de vaccination des petits ruminants est due au recouvrement des coûts des vaccins. Sept foyers de peste des petits ruminants déclarés ont touché 1 502 ovins et caprins dont 264 sont morts. 4. Péripneumonie contagieuse bovine Au cours de l'année 1995, 547 039 animaux ont été vaccinés pendant la vaccination obligatoire du bétail, soit 45 % de l'effectif estimé. Néanmoins, 12 foyers de péripneumonie contagieuse bovine ont été enregistrés, touchant 945 animaux, dont 48 sont morts et 25 ont été abattus. Cette recrudescence de la péripneumonie contagieuse bovine est due au manque de vaccination systématique des animaux en 1994. 5. Maladie de Newcastle La lutte contre la maladie de Newcastle est maîtrisée dans les élevages modernes industriels. Aucun cas n'a été signalé en 1995. n. MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Fièvre charbonneuse Malgré la présence de "champs maudits" dans les régions du Nord et du Centre, aucun cas n'a été rapporté en 1995. 2. Rage La lutte contre la rage continue de préoccuper les Services vétérinaires de Côte d'Ivoire. En 1995, les cliniques vétérinaires publiques et les postes d'élevage ont vacciné 8 400 animaux contre la rage. 5 273 chiens mordeurs ont été mis sous surveillance. - 8 1 •• Maladies des bovins 3. Brucellose bovine La brucellose bovine sévit dans beaucoup d'élevages et reste une grande préoccupation en raison de son incidence économique. Aucun cas n'a été déclaré en 1995. 4. Tuberculose bovine Aucun foyer n'a été déclaré. Cependant, de nombreuses saisies pour tuberculose ont été réalisées dans les abattoirs sur toute l'étendue du territoire. 5. Trypanosomose Au cours de l'année 1995, les enquêtes menées par le projet de lutte contre la trypanosomose animale et les vecteurs dans les zones du Nord, du Nord-Ouest et les zones préforestières donnent une prévalence moyenne de 5 á 11 % dans ces zones, avec des pointes de 20 à 30 % d'infection. La lutte contre cette maladie à grande incidence économique combine l'emploi de trypanocides, la lutte contre les glossines et la promotion du bétail trypanotolérant. -82- C R O A T I A INTRODUCTION The livestock and poultry health status of Croatia is essentially unchanged since the 1994 report. The only important change in the epizootiological situation during 1995 was the occurrence of hog cholera and a considerably smaller number of horses testing positive for equine infectious anaemia.

There were 28 cases, of which 13 pigs died. A total of 126 pigs were destroyed. H. LIST B DISEASES Diseases of multiple 1. species Rabies In 1995, rabies was confirmed in 411 animals of which number 392 were wild animals (foxes) and 19 domestic animals. According to this finding foxes remain the main reservoir and vector of sylvatic rabies. All areas in the Republic of Croatia, with the exception of the Adriatic islands, are infected with rabies. In the Republic of Croatia, there were no human cases of rabies. Oral vaccination of foxes was carried out in autumn in Primorsko-Goranska district. A total of 40,000 vaccinal baits were laid down. 10-94 -83- Diseases of cattle 2. Bovine spongiform encephalopathy Bovine spongiform encephalopathy (BSE) has never been registered in Croatia. Importation of live cattle and their products and bovine genetic material is not permitted from countries in which there have been outbreaks of BSE. Exporting countries that are free of BSE must, have in place either a BSE surveillance programme, or a requirement that BSE is a notifiable disease and that cases of nervous system disorders m cattle are routinely investigated. Diseases of horses 3. Equine infectious anaemia The number of horses in the Republic of Croatia is continuously declining. Equine infectious anaemia is monitored permanently and in 1995 testing of all horses was again carried out in Sisacko-Moslavacka district in the areas along the Sava River. A total of 4,005 of horse blood samples were tested and the disease was confirmed in 69 horses which is for 144 cases or 3.4% less (1994: 5.3%, 1995: 1.9%) if compared to the number of horses with positive sérodiagnostic test results in 1994. All positive animals were killed. The considerably smaller number of positive horses detected m 1995 compared to 1994 is a consequence of the testing carried out in 1994 and the elimination of animals giving positive sérodiagnostic test results in Sisacko-Moslavacka district. Diseases of pigs 4. Tnchinellosis In the Republic of Croatia, the slaughter of pigs and an examination for trichinellosis in meat intended for public consumption must be carried out in registered slaughterhouses. In 1995, trichinellosis was confirmed in only 14 meat samples. The pigs in which Trichinella spiralis was found originated from one small-scale peasant farm. In the areas of the Republic of Croatia where tnchinellosis is known to exist, examination of pigmeat for trichinellosis is compulsory by law as is also the case when slaughtering is carried out by a household for its own needs. In 1995, 43,740 meat samples were examined in 23,535 households. Trichinella spiralis was found in 89 meat samples in 82 households. All infected pigs were slaughtered and their carcases incinerated, as was the meat from slaughtered animals. In these areas ELISA tests on live pigs are also carried out. In 1995, 107 cases of human trichinellosis were registered. -84- C U B A INTRODUCCIÓN El Servicio de Medicina Veterinaria de Cuba, cumpliendo con las funciones que le han sido asignadas por el Estado en lo concerniente a la Protección de las Fronteras, la Vigilancia Epizootiológica, la prevención y la erradicación de las enfermedades, el Control Sanitario de los Alimentos de origen animal para consumo humano y para consumo animal, la Dirección de la Red Diagnóstica del país y el Laboratorio de Control Estatal, ha mantenido una situación zoo sanitaria muy favorable, un Servicio Veterinario Oficial fuerte y estable, y una sólida estructura de atención local. Durante este año se han perfeccionado los Sistemas Locales de Vigilancia y Atención Veterinaria en los 169 municipios que están distribuidos en las 14 provincias del país creándose, además, un consultorio o una clínica en cada uno de ellos. También, eí Servicio Veterinario Oficial, además de cumplir con sus funciones estatales, ha logrado autofinanciarse durante 1995. I.

Se tiene un programa de control muy rígido en todos los sectores y se espera que en 1996 se elimine esta epizootia. 12-94 -85 • II. ENFERMEDADES DE LA LISTA B En la Lista B también, Cuba se encuentra libre de un grupo importante de enfermedades. Las que más problemas presentaron fueron las siguientes: Enfermedades 1. comunes a varias especies Gusano barrenador del ganado (miasis por Cochliomyia hommivorax) Durante este año se reportó por primera vez la presencia de la enfermedad por una encuesta que se realizó en todo el país donde el 59,7% de las muestras fueron positivas. Este diagnóstico fue corroborado por el laboratorio de Referencia de la FAO. Se elaboró un programa nacional de control contra esta enfermedad y se comenzó su aplicación. En octubre nos visitó un experto de la FAO, definiéndose un grupo de medidas para el control de la enfermedad; se discutió la posibilidad de elaborar un proyecto de colaboración técnica para el país y se valoró la necesidad de establecer un programa regional de erradicación. Enfermedades 2. de bovinos Anaplasmosis y babesiosis bovina Se mantienen como enfermedades enzoóticas. Sin embargo, se logró la reducción de los enfermos en un 5 0 % respecto al año anterior debido a las medidas de control contra las garrapatas que se llevan a cabo: se amplió a nuevos territorios la inmunización con la vacuna recombinante de producción nacional contra el boophilus, introduciéndose, además, la lucha por medios biológicos y utilizándose todo esto, junto con la lucha química, como un Sistema Integrado de Lucha contra las Garrapatas. 3. Brucelosis bovina Esta enfermedad se mantiene limitada a algunas zonas del país, con baja incidencia, donde se aplican programas de vacunación, investigación y sacrificio de los reactores. Tenemos el 9 5 % del total del país libre de la enfermedad y la incidencia nacional es de un 0,032%. 4. Tuberculosis bovina De esta enfermedad se presentó un solo caso de focalidad residual. Se mantiene la investigación alérgica a los rebaños así como el diagnóstico pasivo en mataderos realizado por el Servicio de Control Sanitario Oficial de Veterinaria. Enfermedades 5. de ovinos y caprinos Prurigo lumbar Medidas de prevención que aplica la República de Cuba como país libre de la enfermedad. - Permitir solamente la importación de sementales, reproductoras, semen o embriones de las especies susceptibles procedentes de países libres de la enfermedad y realizando un trabajo de rigurosa selección genético-sanitaria que garantice la adquisición de animales no portadores. Las importaciones de embriones desde países afectados, pero procedentes de regiones libres, se pudieran realizar siguiendo la guía de la Sociedad Internacional de Transferencia de Embriones. - Establecimiento de una cuarentena con registros eficientes durante un período de tiempo no inferior al mínimo del período de incubación conocido de la entidad. - Evitar el uso extendido de los sementales hasta tener la certeza de que no sea probable que a través de ellos se transmita. - Prohibir la importación de derivados proteicos destinados a la alimentación de rumiantes procedentes de países afectados. -86- Enfermedades 6. de equinos Anemia infecciosa equina La enfermedad continúa enzoótica en la mayoría de las provincias del pais: se trabaja en la recuperación de las crías de los rebaños afectados y en la separación de los reactores hacia las zonas más afectadas, tratando de ganar territorios libres. Está programado para 1996 comenzar la inmunización con una vacuna producida en el país con la colaboración de la República Popular China. Enfermedades 7. de porcinos Brucelosis porcina La enfermedad se mantiene enzoótica y con una situación más complicada que en otros años, por el incremento de la crianza de animales en áreas urbanas y alrededor de las instalaciones pecuarias, aunque se mantiene y se incrementan las investigaciones apoyándose en el Sistema de Vigilancia Epizootiológica por Cuadrantes Geográficos existentes en el país. Enfermedades de aves de corral Las enfermedades aviares que padecemos están controladas bajo programas de vacunación. Los problemas fundamentales este año se han presentado con la enfermedad de Gumboro, reportándose 67 focos y 905.104 enfermos. Se trabaja además en la inmunización y en la estabilización del programa de bioprotección de las unidades avícolas, prestando especial atención al cambio de carnadas y a la desinfección. IIL O T R A S E N F E R M E D A D E S En Cuba están presentes la mayoría de las enfermedades de la Lista C de la FAO. Las que más problemas nos han causado este año son las siguientes: Enfermedades 1. comunes a varias especies Distomatosis hepática Esta enfermedad es la que más nos afectó en eí año por la falta de productos específicos para el tratamiento de los rebaños comprometidos, lo que determinó que se detectaran en los mataderos más del 2 5 % de los hígados afectados. Enfermedades 2. de porcinos Mal rojo También presentó incrementos en la focalidad durante el año. Se reportaron 2.381 enfermos durante el año, representando el 4 0 % de los ocurridos en el año anterior. Se logró estabilizar la vacunación en las áreas enzoóticas de la enfermedad y disminuir la mortalidad por esta causa. -87- C Y P R U S INTRODUCTION The livestock and poultry health status of Cyprus is essentially unchanged since the 1994 report and the island continued to be free from serious contagious diseases. The Department of Veterinary Services has been nominated by the Director General of the Ministry of Agriculture. Natural Resources and Environment to act as the responsible body for the sanitary part of the World Trade Organization SPS Agreement and as the coordinator between the various departments involved in the SPS Agreement in general.

LIST B DISEASES Diseases of multiple 1. species Echinococcosis-hydatidosis After 1985 it was believed and reported that echinococcosis had been eradicated from dogs, food animals and humans. Sporadic cases of hydatid cysts, which were detected upon slaughter, were mostly considered to have been from animals smuggled from the occupied to the free areas. In 1993 there was indisputable evidence of infection in food animals which were not introduced from the occupied areas. After these findings, detailed investigations were undertaken, covering the period 1989-1993, which showed that the infected animals originated from 58 villages. The reappearance of the Echinococcus cycle in some of the 58 infected villages was attributed to illegal slaughter of infected animals smuggled from the occupied areas or to infected dogs moving from the buffer zone and to government control areas. In the other villages, from the epidemiological evidence, it was concluded that Echinococcus was not eradicated stricto sensu and that its cycle was operating at low levels. In 1995, the Ministry of Agriculture, Natural Resources and Environment continued the application of the scheme for the control of echinococcosis-hydatidosis which was based on the following principles: -88- a) Preventive treatment of high risk dogs, i.e. sheepdogs, dogs from areas where hydatid cysts of sheep and goats were found and dogs from villages situated along the part of the island occupied by Turkish troops, where echinococcosis is endemic. During this campaign, 17,617 dogs originating from 198 villages were preventively treated with praziquantel. b) Introduction of coproantigen ELISA test for the examination of suspected dogs. This test has replaced the arecholine test, which is not considered to be reliable, especially for dogs with low levels of infestation. c) Inclusion of Cysticercus tenuicollis infestation in the list of notifiable diseases to serve as an early warning system for E. granulosus infestation and also as an indicator of illegal slaughtering. Of 299,550 sheep and goats and 16,714 cattle slaughtered during 1995, 33 sheep, 6 goats and 6 cattle were found to be infested with E. granulosus cysts (the respective numbers for 1994 were 44 sheep, 14 goats and 20 cattle). No cysts were reported in slaughtered pigs. 2 Q fever Q fever is sporadic in sheep and goats. Serological screenings is carried out as well as antibiotic treatment. Control of non-vertebrate vectors (ectoparasites) is also applied. In 1995. a total of 999 sera (178 cattle, 300 sheep and 521 goats) were tested, with negative results. Diseases of cattle 3. Enzootic bovine leukosis A national scheme has been in operation since 1987. All dairy cattle over 2 years old are bled and tested for enzootic bovine leukosis (EBL) antibodies. Any positive animals are slaughtered on a voluntary basis without any compensation. There is a restriction on the movement of animals from infected herds and compulsory testing of animals to be sold for breeding or fattening purposes. In 1995. a total of 1,225 cattle, originating from 12 herds with positive animals in any year since 1987, were tested for EBL. One cow was found to be positive and was slaughtered. During the year, 872 serum samples from cattle to be sold for breeding were also tested, and were found to be negative. 4. Infectious bovine rhinotracheitis / infectious pustular vulvovaginitis There was an outbreak of infectious bovine rhinotracheitis / infectious pustular vulvovaginitis (ffiR/TPV) in a dairy farm. The disease was confirmed by virus isolation and ELISA test on pair sera. A modified live virus vaccine was used for control of the disease. In a serological survey of 718 cows (from 61 herds), 100 (from 16 herds) showed antibodies to IBR virus. Diseases of sheep and goats 5. Caprine and ovine brucellosis (B. melitensis) The campaign against this disease was started in 1973 and ended in 1985, achieving total elimination. A test and slaughter policy was followed without vaccination. Monitoring of brucellosis is continuing with annual statistically reliable blood sampling and laboratory tests. No new cases have occurred since 1985, with the exception of an outbreak in a flock in 1993. A stamping-out policy was implemented, all animals in the flock being immediately slaughtered. It is suspected that the disease was introduced from the occupied areas by the illicit movement of animals. In 1995, 19,481 blood samples from sheep and goats and 1,110 blood samples from cattle were tested, with negative results. -89- 6. Scrapie For the control of scrapie, a national control scheme has been in operation since 1987. The operating structure of the scheme includes among other activities the following: a) The confiscation of clinically suspected animals, which are slaughtered in the model slaughterhouse of the Department, with histological confirmation of diagnosis. After confirmation of diagnosis, confiscation and slaughter of their progeny and parents. b) Confiscation and slaughter of entire flocks with a high incidence of proven scrapie. c) Suspected and infected flocks are placed under quarantine and their premises are regularly disinfected with sodium hydroxide. During 1995. the disease was confirmed in 18 new flocks. The total number of infected flocks was 63, and 944 sheep and 169 goats were confiscated and slaughtered. Out of 614 sheep and 140 goat brains which were examined histopathologically, 267 sheep and 37 goats were found to be positive. 7. Maedi-visna There was serological evidence only. Out of 1,122 sera (563 sheep and 559 goats from 45 flocks examined), 94 (89 sheep and 5 goats from 15 flocks) were found to be positive. Diseases 8. ofpigs Transmissible gastroenteritis No clinical signs of transmissible gastroenteritis (TGE) were seen during 1995. Out of 219 sera from sows which were tested with ELISA, 22 were found to be positive for TGE antibodies. These sows originated from herds that had clinical disease during 1994. Diseases of poultry 9. Avian infectious bronchitis Infectious bronchitis is sporadic. A problem of nephritis caused by nephrotropic strains appears from time to time in broilers. The use of certain vaccines for this form of the disease has proved helpful. 10. Avian infectious larvngotracheitis Infectious laryngotracheitis is diagnosed quite often, especially in broilers. Although it varies in severity it is always a serious threat because it aggravates other respiratory conditions. When the diagnosis is confirmed by laboratory tests, vaccination in the affected farms is recommended for a period of time. 11. Infectious bursal disease (Gumboro disease) Gumboro disease is of major concern. Due to various vaccination programmes which are applied in almost all farms, losses from outbreaks are relatively low. 12. Marek's disease Outbreaks of Marek's disease due to vaccine breaks occur from time to time. All day-old chicks are vaccinated and the disease is under control. The impact on the minimization of the above diseases, as well as the other poultry diseases in general, from the use of the all in - all out system is stressed to the farmers who are strongly advised to adopt it. Diseases of fish and molluscs There were no outbreaks of List B diseases of fish and molluscs. -90- Other 18. diseases Leishmaniosis The preliminary programme for the study of canine leishmaniasis which was started in 1994 in cooperation with the School of Medicine, Institut Santé et Développement, Paris, continued during 1995. Serum samples from dogs and human earners of the human immunodeficiency virus were sent to the above institute. Out of 370 serologically tested dogs and 73 humans, 46 dogs and 11 humans showed antibodies against Leishmania infantum. Further investigation is needed in order to establish diagnosis using culture, isolation and identification of the parasite. TIL OTHER DISEASES 1. Spotted fever group rickettsiae (SFGR) The project "Study of spotted fever group Rickettsiae: Application of current molecular biology techniques", which was adopted by the Council of Ministers of the European Communities and started to be applied in 1994 in cooperation with the University of Crete (Greece) and the University of AixMarseille (France), continued during 1995. The main objective of this research is to detect current areas of SFGR in Greece and Cyprus. The above aim is to be accomplished through three specific objectives: 1. Recognition of geographic areas in Crete and Cyprus with a high prevalence of SFGR using screening (indirect immunofluorescence) and specific methods (Western blot). 2. Identification of SFGR from ticks collected in the above areas, using rapid genomic techniques (PCRRFLP). 3. Isolation and identification of rickettsiae from fébrile patients in the above areas. Human sera were examined for antibodies against Rickettsia results. conori, C. burnetii and R. typhi with positive R. conori was isolated from ticks collected from dogs, sheep and goats, and dog sera were examined for antibodies against R. conori with positive results. 2. Salmonella enteritidis infection Cases of Salmonella enteritidis in poultry were further reduced to only 5. Acquaintance with the disease, the use of acidifiers in food and the use of vaccines have greatly contributed to the control of the infection. -91 - C Z E C H R E P U B L I C L LIST A DISEASES Disease present in 1995 Total 1994 3 Classical swine fever Diseases never Total 1995 1 Jan 0 Mar 0 Apr 0 May 0 1995 Jun Jul Aug Sep Oct 0 0 0 0 0 0 F.P.

The outbreak occurred in a mixed breeding and fattening pig farm. Stamping-out method was applied. Subsequent serological and virological measures applied to detect infection in pig holdings in the infection and surveillance zones gave negative results. Wild boars The disease is controlled by means of a surveillance programme applied to all wild boars, whether killed during hunting or found dead. The animals are subjected to post mortem veterinary inspection and laboratory tests. Of 3,667 samples submitted for serological screening, 98 gave positive reaction. II. LIST B DISEASES Multiple species 1. diseases , Auieszkv s disease The Czech Republic has been free of Aujeszky's disease since 1987. The surveillance programme has been in force since then. During the reported period, 183,728 serological tests were performed, all with negative results. 2. Rabies Annual compulsory vaccination of dogs prevents the urban form of rabies. The oral immunisation programme, which started in 1989, continued in 1995 in all rabies-infected districts. A total of 1,649,680 baits for oral immunisation of foxes (749,680 in spring and 900,000 in autumn) were distributed. The positive influence of oral vaccination can be confirmed by the substantial 05-94 -92- decrease in rabies-positive findings. There were 178 cases of rabies recorded (157 red foxes, 8 wild animals). Diseases of cattle 3. Bovine brucellosis and tuberculosis The Czech Republic has been officially free from bovine brucellosis since 1964 and from bovine tuberculosis since 1968. A serological survey is performed every year. 4. Enzootic bovine leukosis The eradication programme is nearly at the end. The number of infected farms has been reduced to two. 5. Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis The eradication programme has been divided into several stages. The first period was successfully completed in 1995 in all semen collection centres. Selected herds are gradually being incorporated into the programme. 6. Bovine spongiform encephalopathy There was no occurrence of the disease in 1995. Histopatological examination of the central nervous system is carried out in cases of nervous clinical signs in ruminants. Diseases of horses 1 Equine viral arteritis A serological testing programme was carried out, especially during the mating period (in stallions and mares used for breeding purposes). Of 5,624 serological tests, 14.4% gave positive results. 8 Contagious equine metritis Surveillance testing continued this year. In total, 2,450 samples were checked, of which 12 were positive. Diseases of 9. lagomorphs Myxomatosis Vaccination is carried out in the entire state territory. Outbreaks are reported in backyard farms only. 10. Viral haemorrhagic disease of rabbits Outbreaks occur predominantly in backyard farms. Preventive vaccination is carried out. Diseases of fish 11. Spring viraemia of carp Antibodies are found in some young fish in breeding establishments, but no clinical signs have been observed to date. Diseases of bees 12. Varroasis Despite regular varroa treatment (spring and autumn) and very good cooperation of beekeepers, varroasis is widespread in the Czech Republic. CHILE INTRODUCCIÓN Implementación del Sistema Nacional de Emergencia Sanitaria Animal Con fondos especiales entregados por el Ministerio de Agricultura se está implementando el sistema nacional de emergencia sanitaria animal. El sistema contempla un plan de detección precoz de enfermedades emergenciales, un plan orgánico funcional de emergencia sanitaria y planes de contingencia para las principales enfermedades exóticas para Chile. Plan de vigilancia de enfermedades 1 En el marco del Proyecto de Modernización de Gestión SAG-BID se realizaron las actividades de vigilancia y monitoreo sanitario tanto de enfermedades exóticas para avalar y certificar ausencia de enfermedad ante organismos sanitarios, como de enfermedades prevalentes con el fin de desarrollar diagnósticos de situación para evaluar la factibilidad de control y erradicación. Se realizaron 15.290 diagnósticos que incluyeron a bovinos, ovinos, caprinos, porcinos, equinos, camélidos y aves. Implementación Privados del Sistema Nacional de Acreditación de Médicos Veterinarios y Laboratorios de Diagnóstico Se dio inicio al plan de acreditación de veterinarios y laboratorios privados, que tiene por objetivo aumentar la capacidad operativa del servicio veterinario oficial para cubrir acciones de control sanitario, vigilancia y certificaciones en el ámbito de los proyectos que ejecuta el SAG.

Sistema de prevención de la fiebre aftosa en campos de cordillera Durante la temporada de 1995 las actividades de control sobre la población animal susceptible entregó como resultado un total de 946.633 animales inspeccionados, lo que se tradujo en 2,39 inspecciones por animal en la temporada. 2. Peste porcina clásica La peste porcina clásica está bajo un proyecto nacional de erradicación. En 1995 sólo se ha presentado un foco de peste porcina clásica, en un pequeño grupo de cerdos en la zona norte del país, alejada de los principales centros de producción porcina. 3 Enfermedad de Newcastle La enfermedad de Newcastle fue erradicada en 1975.

El plan contempla la vacunación sistemática con cepa 19 de las terneras de entre 3 y 8 meses, la ejecución de acciones de vigilancia y detección de rebaños infectados con ejecución de planes de saneamiento obligatorios en éstos, y la eliminación de los animales positivos. En 1995 se vacunaron 225.449 terneras con cepa 19, sobrepasando la meta establecida de 200.000. Se inició oficialmente la erradicación de la enfermedad en las provincias de Chiloé y Palena (región de Los Lagos). Sistema de certificación de predios libres de brucelosis, tuberculosis y leucosis bovina Es un programa de tipo voluntario y se desarrolla en las regiones de Bío-Bío, La Araucania, y Los Lagos.

Some of the cases were linked together due to contact via local markets while the source of origin has not been established for most of the cases despite thorough epidemiological investigations. However, no cases could be linked to the commercial poultry production. In 1995, 7,772 blood samples from commercial holdings were tested negative for Newcastle disease as part of the Danish routine monitoring programme for Newcastle disease. In accordance with Council Direc­ tive 92/66/EEC of 14 July 1992 introducing Community measures for the control of Newcastle disease in each case the infected flock was killed and destroyed and the premises cleansed and disinfected. At the same time a protection zone (3-km radius) and a surveillance zone (10-km radius) were established. When the first case was diagnosed on 12 October 1995 (paramyxovirus type 1, ICPI > 0,7) a ban on markets and exhibitions for poultry, including pigeons was introduced for the whole of Denmark. This ban was extended to a ban on movement of poultry from one holding to another from 15 December 1995. The commercial poultry sector was not affected by the ban as the tightening up of rules for movement of poultry was due to the disease outbreaks occurring in the non-commercial part of the poultry population only. 1972 -97- II. LIST B DISEASES 1. Aujeszky's disease in December 1992 Denmark was recognised as free from Aujeszky's disease by the EEC (Commission Decision 93/24/EEC). No outbreaks or seroreactions of Aujeszky's disease were recorded during 1995, Monitoring to ensure continued freedom was carried out on blood samples from slaughterhouses. All breeding boars, boars over 140 kg (live weight) and 10% of the sows were tested before slaughter or export. In 1995 a total of 62,692 boars and sows were tested. The Aujeszky's disease control and eradication programme was described in the 1989 and 1992 editions of The Animal Health and Disease Control Position in Denmark, a booklet published by the Danish Veterinary Service and forwarded to OIE Member Countries. 2. Echinococcosis-hydatidosis Hydatid cysts are recorded in cattle at abattoirs on a few occasions. 3. Leptospirosis Serological examinations of bovine and porcine sera indicate a low incidence of infection. No clinical cases reported. 4. Q fever Q fever has not been recorded during 1995. Positive reaction in one bovine serum sampled in connection with pre-export examination indicated an exceptional occurrence. No clinical signs have been reported. 5. Rabies In September 1985. bat-rabies was diagnosed for the first time" in Denmark. Since then a surveillance programme for bat-rabies has been running. Under this programme, 13 bats were submitted for exa­ mination during 1995. Rabies was diagnosed in one of these. Seven specimens from mammals other than bats (three cats, one dog, one rat, one mouse and one squirrel) were submitted during 1995 and examined with negative results. 6. Paratuberculosis Paratuberculosis has never been diagnosed in sheep or goats in Denmark. The disease is not controlled officially but since 1979 it has been possible for owners of cattle herds with clinical problems to use vaccination, subject to permission from the Danish Veterinary Service. In 1995, 125 herds have had permission to vaccinate, 17 new permissions were given during the year. Diseases of cattle 7. Bovine brucellosis According to E E C Commission Decision 79/837/EEC, all Danish cattle herds are regarded as officially free from brucellosis as long as the country remains free from clinical outbreaks. Bulls at AI centres are tested before entry and thereafter monitored by annual tests. 8. Bovine genital campylobacteriosis In accordance with Council Directive 88/407/EEC all bulls must be tested with negative results for Campylobacter fetus in the isolation accommodation before entering the approved semen collection centre, and all bulls in semen production in the semen collection centre are tested at least once a year. In 1995, one case of C. fetus was diagnosed during pre-entry isolation. The affected animal was isolated, treated and retested with negative result, and contact bulls were treated and retested with negative results. -98- 9. Bovine tuberculosis According to EEC Commission Decision 80/984/EEC all Danish cattle herds are regarded as officially free from tuberculosis. Monitoring is done through meat inspection. Routine tuberculosis tests of cattle are not carried out. 10. Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis In December 1992 Denmark was recognised as free from infectious bovine rhinotracheitis (B3R) by EEC Commission Decision No. 93/42/EEC. In 1995, 61 herds were found infected. Most of them were beef herds infected in connection with an outbreak caused by spreading of the infection from a traders herd. After slaughter of reactors and control tests all 61 herds were again declared IBR-free. 11. Bovine spongiform encephalopathy No case of BSE has occurred since August 1992. On 10 August 1992, BSE was diagnosed in a five-year old Highland Cattle cow imported into Denmark from the United Kingdom in 1988. The clinical suspicion arose 8 July and no animals were allowed to be removed from the premises. The herd consisted of two separate flocks - in total 25 bulls, cows, heifers and calves The affected cow was killed 14 July after having shown increasing nervous signs including uncoordinated movements, nasal discharge, salivation, reluctance to eat, difficulties to drink and changed behaviour in general for about ten days, she had, however, been loosing weight since January. After collection of brain material for laboratory examination at the Danish Veterinary Laboratory the carcass was buried on the spot. The diagnosis was confirmed by the Central Veterinary Laboratory, Weybridge. Some nervous signs, salivation and weight loss were observed in another cow imported from another herd in the United Kingdom in 1989. The histological examination of brain material from this cow showed no evidence of BSE. No other animal in the herd showed any clinical signs. The affected animal as well as her offspring had remained in the importing herd. All cattle on the affected farm were moved to the Danish Veterinary Institute for Virus Research, Lindholm, to be killed and incinerated. Thorough cleaning and disinfection of the premises was carried out, and grass fields were ploughed. In view of the strict measures taken, the Danish cattle population is still considered to be free from BSE. BSE is notifiable in Denmark, and a ban on feeding of ruminant protein to ruminants has been in force since June 1990. Diseases of sheep and goats 12. Caprine and ovine brucellosis (excluding B. ovis) Denmark has been declared free from Brucella melitensis by Commission Decision 93/52/EEC. 13. Capnne arthritis/encephalitis The disease, which has an enzootic occurrence, is mostly recorded as serological findings, as it is included in the voluntary maedi-visna control programme (see below). 14. Maedi-visna A voluntary control programme has existed since 1979. The programme is run by the agricultural organisations. At the moment 2,500 herds of sheep and goats have free status. Diseases of horses 15. Contagious equine metritis During 1995, Taylorella equigenitalis basis prior to the breeding season. was isolated from two stallions which were examined on a private -99- 16. Equine viral arteritis Serological examinations have shown that the virus is present in the Danish horse population, especially among racehorses which compete abroad there is a high incidence of serological reactors. The disease is regarded as being of little importance as clinical cases are rarely recognised. Abortions have not been reported. Diseases 17. ofpigs Atrophic rhinitis Clinical disease occurred enzootically, and the meat inspection data showed 0.28% of the pigs having detectable shortening or deflection of the snout. 18. Trichinellosis The disease has not been recorded in domestic pigs since 1930. All pigs slaughtered at Danish export slaughterhouses are examined for Trichinella spiralis. During 1995 samples from 19,431,485 pigs were examined, and none of the samples were found to contain T. spiralis. It is also compulsory to examine slaughtered wild pigs. In 1995, 1,484 were examined, and none of them were found to contain T. spiralis. All horses which are slaughtered at Danish export authorized slaughterhouses and approved for intraCommunity trade are examined for T. spiralis. During 1995 samples from 776 horses were examined, and none of the samples were found to contain T. spiralis. A programme of examining 3,000 red foxes was initiated in December 1995. It is hoped that Denmark can be recognised as Trichinella free in due course. Diseases of 19. lagomorphs Myxomatosis The infection is regarded as persistent in a wild population of rabbits found on the island of Fano (close to the west coast of Jutland), and transport of rabbits and hares from this island is restricted. In 1995, one outbreak was recorded in a small rabbit flock in the area of Copenhagen. The flock had had illegal contact with rabbits on Fano. Diseases of fish 20. Viral haemorrhagic septicaemia There are 489 fresh water trout farms operating in Denmark and 8 7 % are registered as free from viral haemorrhagic septicaemia (VHS). Eleven outbreaks of VHS were recorded during 1995. Eight of these outbreaks were reinfections in formerly VHS-free farms. Furthermore, 13 fish farms situated downstream of an infected fish farm have been placed under restrictions, and have or will undergo the same depopula­ tion and disinfection procedures as infected fish farms. Seven farms, all located in brackish water, and two farms located in sea water were also infected with VHS during 1995. VHS-free farms can only receive fish, eggs and fingerlings from other VHS-free farms. Fish farms are inspected regularly by the Danish Veterinary Service. Trade in aquaculture fish and products for reproduction is controlled by The Danish Veterinary Service. A part of Denmark is according to Commission Decisions 93/74/EEC and 94/450/EEC approved zones concerning VHS, and 118 of the Danish fresh water farms are situated in these zones. Besides, nine aquaculture farms situated in the non-approved zone have been approved concerning VHS according to Commission Decision 95/336/EEC. -100 - 21. Infectious haematopoietic necrosis Infectious haematopoietic necrosis has never been recorded. According to Commission Decision 93/74/EEC, Denmark is an EEC-approved zone concerning infectious haematopoietic necrosis. III. OTHER DISEASES Infectious pancreatic necrosis in trout The agent of infectious pancreatic necrosis (IPN) is widespread in trout farms situated at larger streams, but approximately 40 fish farms situated at wells, boreholes, or at the top of small streams are registered as D?Nfree brood stocks. They are intensively inspected and virologically tested. About 35 fish farms supplied with eggs or fry from the above mentioned farms and with approved water supply are registered as IPN-free produc­ tion farms. They are inspected twice a year and virologically tested once a year. -101 - E C U A D O R L ENFERMEDADES DE LA LISTA A Panorama general Enfermedades señaladas en 1995 Fiebre aftosa - Virils O Estomatitis vesicular - Virus Indiana Enfermedades nunca Total 1994 23 0 Feb 1 0 Mar 0 0 Abr 2 0 May 0 0 1995 Jun Jul 0 0 0 0 F.P.

This new policy aims to improve the veterinary services offered. Under the ETS, animal holders must pay for or share the cost of these services, by paying a reduced fee for animal treatment in addition to the cost of pharmaceutical products. Money collected is used for maintenance, purchasing of medicines, equipment, transportation, incentives to personnel working in these activities, etc. In 1993. studies were performed for the privatisation of veterinary services, starting with liberalisation of artificial insemination services. Thirty-four official veterinary officers have signed contracts to work as private veterinarians in this respect. Vaccination campaigns represent a heavy financial burden on the government's budget. It has been decided that vaccination against diseases of socio-economic importance must remain within the domain of the Veterinary Authorities. Such diseases include rinderpest, Rift Valley fever, foot and mouth disease, sheep pox and haemorrhagic septicaemia. The use of other animal vaccines and all poultry vaccines is at the discretion of veterinarians participating in the Egyptian Veterinary Syndicate. Epidemiological Unit Six epidemiological units (EPU) were established at the governorate level. The planned computerisation of epidemiological activities is due to be implemented throughout Egypt. Laboratory results and data obtained from sero-surveillance of foot and mouth disease and Rift Valley disease were computerised and analysed epidemiologically. Continuous reports on this analysis were submitted to the chairman of the General Organisation for Veterinary Services (GOVS). Training courses on epidemiology and computers were continued either in Egypt or Germany. Surveillance operations The disease surveillance system is continuously operated throughout the country by official veterinarians working in different positions in the field, in abattoirs, on vaccination campaigns, in quarantine stations, etc. Notification of suspected diseases can also be received from livestock owners or members of the public. After receiving notification that the occurrence of a notifiable disease is suspected, the chairman of the GOVS may immediately direct a diagnostic team to investigate and provide an expert opinion. Sero-surveillance is now performed for three main reasons: 1. To assess the immune status after vaccination campaigns for rinderpest, FMD, RVF and lumpy skin disease. 2. To detect any viral or bacterial activity such as for rinderpest, brucellosis or tuberculosis. 3. In accordance with the recommendations of the European Community, the GOVS is conducting a pilot sero-surveillance scheme aimed at equine diseases (African horse sickness, glanders, dourine and infectious equine anaemia). Tests for theses diseases are performed at National Laboratories and are checked and confirmed by Reference Laboratories. -103- I.

Sero-surveillance is carried out after the vaccination campaigns. The estimated number of sera to be collected is 5,000 samples to be tested by ELISA.

Disease surveillance and serosurveys have clearly demonstrated the absence of any rinderpest virus activity. This statement has encouraged the Veterinary Authorities in Egypt to declare that Egypt is provisionally free from rinderpest. Steps are now being taken to stop vaccination against the disease. A total of 480,499 cattle and 236,463 buffaloes were vaccinated against rinderpest in 1995 3. Lumpy skin disease The first outbreak of lumpy skin disease in Egypt was in 1988 and lasted until 1990. Vaccination campaigns with locally produced sheep pox vaccine are carried out annually. Under the American Project 416 B, several activities relating to this disease are under way to produce a specific vaccine using the local isolate of lumpy skin disease virus, and to measure the antibody response, which is extremely good in cows having received more than two shots of the sheep pox vaccine. The 09-94 -104- duration of immunity in cattle after the first vaccination is also being assessed. The number of cattle vaccinated in 1995 was 1,386,503. 4. Rift Valley fever The first appearance of this exotic disease was in 1977, and lasted until 1980. From 1980 until the limited outbreak in Aswan governorate during June-July 1993, control measures depended mainly on using an inactivated Rift Valley fever (RVF) vaccine produced locally. Vaccination initially covered only 2 0 % of the susceptible animal population, but has reached 4 0 % in the last two or three years due to an increase in vaccine production. During the intervening 13 years (1980-1993), disease surveillance and serological tests confirmed the absence of RVF virus activity and the 1993 outbreak in Aswan governorate is in fact considered to be a new introduction. A total of 5,000 serum samples were collected from susceptible animals in different governorates to assess the immunological status of vaccinated animals. Laboratory results indicated protective immunity against RVF. Mosquito larvicidal treatment of drainage channels was used in association with fogging, aerosol and animal spraying with effective insecticides. Number of animals vaccinated against Rift Valley fever in 1995 Cattle 883,251 Buffaloes 692,725 Sheep 1,135,696 Goats 139,414 Camels Total 5. 51,233 2,902,319 African horse sickness Previously, control measures depended on vaccination against the disease with a locally produced polyvalent attenuated vaccine, which was carried out all over the country up to 1984. Since then, vaccination has been carried out only in the southern border governorates, as a preventive measure against potential introduction from the south. Starting from May 1994, vaccination has been stopped in these border governorates. In line with a European Commission recommendation, Egypt has carried out an epidemiological screening survey for African horse sickness and List B diseases such as dourine, glanders and equine infectious anaemia. Tests for these diseases carried out at national and international reference laboratories have indicated that Egypt is free from these diseases. A total of 385 equine serum samples were collected and tested at AHRI using ELISA. results were negative for African horse sickness virus activity. The laboratory The Commission of the European Communities decided in 1995 to add Egypt to the list of countries from which imports of registered horses into the European Community are permitted. 6. Highly pathogenic avian influenza (fowl plague) Egypt has been free from the disease since 1965 and no vaccination is carried out. 7. Newcastle disease This disease still represents a major problem to the poultry industry in Egypt. In spite of periodic vaccination against the disease using local and imported vaccines, outbreaks still threaten poultry farms. In 1995, there were five outbreaks in five governorates. -105- II. LIST B DISEASES Diseases of multiple 1. species Rabies The main method to control rabies in Egypt is the destruction of stray dogs and cats. Owners of dogs and cats must register their animals and have them vaccinated against the disease. The number of dogs vaccinated in 1995 was 4,722. The total number of stray dogs and cats destroyed in 1995 was 205,393 (196,837 dogs and 8.556 cats). Diseases of cattle 2. Brucellosis This disease is frequently recorded in Egypt. Although the incidence of the disease is low its effects on livestock and the human population cannot be underestimated. A national programme with the aid of American Project 416 B to control or eradicate brucellosis in Egypt is, therefore, currently being implemented. The policy of test and slaughter is adopted in Egypt, with fair compensation being paid to animal owners. Vaccination is carried out as follows: for cattle (optional for female calves of 3 to 7 months of age), using strain 19 vaccine, and for ewes and goats using Rev-1 vaccine.

Vaccination against this disease is applied twice for broilers and five times for layers. -106- 5. Pullorum disease (Salmonella pullorum) This disease is endemic in Egypt and chiefly affects small poultry farms. Laying hens are usually tested using the rapid pullorum test and positive cases are slaughtered. III. OTHER DISEASES Coccidiosis Several species of Eimeria were isolated from several poultry farms, the most prevalent species being E. tenella. Veterinary drugs are usually used in order to save newly hatched chicks. -107- E S P A Ñ A INTRODUCCIÓN La evolución de la sanidad animal en el Reino de España durante el año 1995 puede ser calificada de manera general de satisfactoria, dada la rapidez y eficacia con que los Servicios Oficiales han respondido a las incidencias que se han presentado y por la eficiencia en la ejecución de las Campañas de Saneamiento Ganadero. Sin lugar a dudas, el hecho más importante que se ha producido en este año ha sido lograr, después de 35 años de lucha, la erradicación de la peste porcina africana en la totalidad del territorio español. Esta notable mejora de la situación sanitaria queda reflejada en la ausencia en nuestro país de enfermedades de la Lista A de la OIE. En relación con las enfermedades de la Lista B, en este informe se detalla la situación de aquellas que por sus repercusiones económicas en unos casos o por su condición de zoonosis en otras se consideran de mayor interés. No obstante, durante 1995 han aparecido en España algunos casos de otras enfermedades de la Lista B que en ciertas ocasiones son de difícil cuantificación, como ocurre con la equinococosis/hidatidosis, leptospirosis, paratuberculosis, babesiosis bovina, rinotraqueitis infecciosa bovina/vulvovaginitis pustular infecciosa, agalaxia contagiosa, gripe equina, sarna equina, rinitis atrófica del cerdo, cisticercosis, bronquitis infecciosa aviar, bursitis infecciosa, enfermedad de Marek, mixomatosis, enfermedad hemorrágica viral del conejo, acariasis de las abejas, varroasis y leishmaniosis.

Peste porcina africana El año 1995, ha sido un año primordial en la historia de la sanidad animal en España y más concretamente en el sector porcino, ya que después de 35 años de lucha contra la peste porcina africana, se ha conseguido su erradicación en la totalidad del territorio español. La óptima evolución de esta enfermedad en los 111 municipios de la Comunidad Autónoma de Andalucía (11 en zona afectada y 100 en zona de vigilancia), tal y como se estableció en la Decisión 94/887/CE, ha llevado a lo largo de este año 1995 a que la Comisión de las Comunidades Europeas, previo dictamen favorable del Comité Veterinario Permanente, aprobara la Decisión 95/300/CE mediante la cual quedaron tan sólo 51 municipios como zona de vigilancia, y la Decisión 95/493/CE que declara la totalidad del territorio español como indemne de esta enfermedad. A esta última Decisión, se ha llegado gracias al silencio epizoótico de 21 meses transcurridos desde el último foco clínico de la enfermedad, ocurrido el 23 de febrero de 1994 en el municipio de Alanis de la Sierra, provincia de Sevilla, así como por los resultados de los 598.651 controles serológicos efectuados en Andalucía, con tan sólo una positividad de 0,0006%, y de los 686.747 controles serológicos en el resto de España, con resultados negativos. Ante esta excelente situación, el Comité Veterinario Permanente en reunión celebrada el 6 de noviembre de 1995 emitió un dictamen favorable a la propuesta de la Comisión, que fue aprobada por unanimidad, y de forma excepcional por aclamación, como homenaje por el excelente trabajo realizado por España. Por dicho dictamen, la Comisión de las Comunidades Europeas adopta la Decisión 95/493/CE por la que se deroga la Decisión 94/887/CE reconociendo el status de libre de peste porcina africana para España a partir del 1 de diciembre de 1995. Esta Decisión 95/493/CE ha sido transpuesta a la legislación nacional mediante la Orden del 5 de diciembre de 1995. El seguimiento y control de esta enfermedad quedan asegurados mediante las medidas adoptadas por el Real Decreto 1493/1995 del 8 de septiembre por el que se establece el Plan de Seguimiento Sanitario del Ganado Porcino. Con esta disposición se mantiene un sistema de vigilancia mediante investigaciones serológicas sobre diversas enfermedades del cerdo, incluida la peste porcina africana. -109 - Investigación serológica en zona libre de peste porcina africana COMUNIDAD AUTÓNOMA ANIMALES CHEQUEADOS Andalucía Aragón Asturias Baleares Canarias Cantabria Castilla - La Mancha Castilla y León Cataluña Extremadura Galicia Madrid Murcia Navarra País Vasco La Rioja Valencia TOTAL (1995) POSITIVIDAD Positivos % 13.631 0 0 14.000 0 0 - 0 0 5.957 0 0 3.893 0 0 0 0 31.648 0 0 130.768 0 0 54.315 0 0 369.750 0 0 11.884 0 0 3.224 0 0 39.988 0 0 4.026 0 0 - - - 1.256 0 0 2.024 0 0 686.747 0 0 383 II. ENFERMEDADES DE LA LISTA B Durante el año 1 9 9 5 ha continuado llevándose a cabo los programas de lucha y erradicación frente a la tuberculosis bovina, brucelosis bovina, brucelosis ovina y caprina y leucosis bovina enzoótica. Hay que destacar el gran esfuerzo técnico y económico realizado en la ejecución de las campañas realizadas en estas enfermedades, como así lo demuestra el aumento en el número de animales chequeados, en relación con el año 1 9 9 4 . El número de establos investigados en el año 1 9 9 5 ha disminuido debido a la reducción en el número total de establos por la reestructuración que está sufriendo el sector lácteo. Cabe destacar la mejora en la situación epidemiológica en España, como queda reflejada en la disminución de los porcentajes de positividad en todas estas enfermedades en relación con el año 1 9 9 4 . Enfermedades 1. comunes a varias especies Rabia Subsiste el problema en la ciudad de Melilla, contabilizándose 6 casos en perros que dieron resultado positivo a la prueba de inmunofluorescencia. Se han seguido manteniendo prácticamente las mismas medidas de control de desplazamiento de perros desde Ceuta y Melilla hacia la península, así como la vacunación gratuita de todos los perros de estas dos ciudades. Se continúa con las campañas de vacunación en la mayor parte del territorio español. Enfermedades 2. de bovinos Brucelosis bovina Se ha continuado en el año 1 9 9 5 la lucha frente a esta enfermedad, aumentando respecto a 1 9 9 4 el número de animales chequeados en un 1,5%. En el año 1 9 9 5 , se han controlado 2 3 3 . 5 6 5 establos, de los cuales el 9 7 , 2 3 % resultaron libres de esta enfermedad, porcentaje superior al obtenido en 1 9 9 4 ( 9 6 , 5 2 % de establos libres).

Tuberculosis bovina El programa de erradicación frente a esta enfermedad ha continuado en el año 1995, aumentando respecto a 1994 el número de animales chequeados en un 5,4%. Se ha producido una mejoría en la situación sanitaria, habiendo disminuido los porcentajes de positividad frente a esta enfermedad, como ha venido sucediendo en los últimos años. Así en 1994, el 94,32% de establos que estaban libres de enfermedad, han pasado al 94,79% en 1995. Asimismo, el índice medio de animales positivos ha bajado al 1,28% en 1995, frente al 1.63% en 1994. Debe señalarse que prácticamente el 100 % de la ganadería de producción de leche está bajo control, habiéndose extendido en estos últimos años a la ganadería extensiva de razas autóctonas, estando en previsión revisarla en su integridad, incluida la raza de lidia, a lo largo de los próximos años. Hay que destacar que determinadas Comunidades Autónomas están muy próximas a lograr la erradicación de la enfermedad. Cantabria, Asturias Galicia, Navarra y País Vasco han controlado casi el 100% de los establos y el porcentaje de establos libres oscila entre 9 8 % y 99%. El porcentaje de animales que presentaron una reacción positiva fue de 0,09% en el País Vasco y de 0,39% en Navarra.

Muchas Comunidades Autónomas de la Cornisa Cantábrica han dejado la política de vacunación de los animales jóvenes. Durante el año 1995 ha aumentado el número de animales investigados frente a 1994 en un 36%. Este espectacular ascenso en el número de animales controlados se debe a dos factores, a saber: intensificación de la campaña a nivel nacional e inicio del sistema de erradicación por control y sacrificio de los animales positivos en la Comunidad Autónoma de Castilla y León. El número de establos libres de esta enfermedad ha disminuido del 76,52% en el año 1994 al 75,8% en el año 1995; el número de animales seropositives ha disminuido del 3,17% en 1994 al 2,84% en 1995. Cabe señalar que en las Comunidades Autónomas de Asturias, Baleares, Canarias, País Vasco, Galicia y Navarra se ha chequeado la casi totalidad de los censos con índices de positividad que oscilan entre el 0,0% de la Comunidad Autónoma de Canarias y el 0,64% de la Comunidad Autónoma de Asturias.

The programme is financed by the State government and executed by the State district veterinary organisation. All cows are tested serologically and positive animals are slaughtered. In 1995, a total of 257,843 animals were tested for enzootic bovine leukosis with 1,014 (0.4%) being positive. -113- E T H I O P I A INTRODUCTION Establishment of Animal Health Research Centre The New Animal Health Research Centre (NAHRC) is located in Sebeta, about 28km from Addis Ababa. It is constructed on 60ha of land at the cost of 20 million Birr (ETB) by the 4th Livestock Development Project of the Ministry of Agriculture which was funded by the World Bank loan. The centre has four Departments (Department of Microbiology, Department of Parasitology, Department of Pathology and Department of Pharmacology, Toxicology and Biochemistry) and an Epidemiology Unit. The centre has a total of 130 staff which include 20 research officers, 30 experienced technicians and 80 administrative and supporting staff. The objectives of NAHRC are: - to carry out applied research work on livestock diseases of economic importance: - to carry out epidemiological studies of livestock diseases based on priorities; - to investigate disease outbreaks that are beyond the capability of the regional veterinary laboratories; - to cater as a diagnostic reference laboratory for the nation. The centre has, apart from the huge laboratory buildings, 33 residential houses, administrative building, incinerator, experimental animal houses, stores and a canteen.

The 1993 strategy divided the country into endemic areas, epidemic areas and areas regarded as free from rinderpest, based on the available information about the rinderpest disease situation. From June 1993 onwards, PARC-Ethiopia purposely stopped vaccinating in all epidemic areas and areas regarded as free from rinderpest. The basic rinderpest eradication strategy remained the same, to device and carry out vaccination campaigns aimed at eradicating rinderpest from endemic foci and preventing the spread of rinderpest to epidemic and areas regarded as free from rinderpest, through the establishment of sanitary cordons with a high immunity level. The vaccination achievements are monitored by sero-surveys. Through disease survey work, the geographical boundaries of the endemic areas and sanitary cordons are continuously redefined. The rinderpest disease history in the epidemic areas is established through questionnaire surveys, in preparation for sero-surveys. Disease and sero-surveillance is performed in areas regarded as free from rinderpest. This is a preliminary national exercise to be followed by the OIE pathway on steps to declare an area free from rinderpest as part of the Global Rinderpest Eradication Programme (GREP). The effectiveness of the strategy is evidenced by the gradual decline of the number of rinderpest outbreaks being reported from the field. Currently, rinderpest is confined in few remote corners of the country, in cattle herds belonging to pastoral and semi-pastoral people under extensive management systems. To improve vaccination coverage and efficiency of vaccination in these remote and inaccessible areas, alternative vaccine delivery systems using Community Animal Health Workers (CAHWs) and thermo­ stable vaccine, is introduced by PARC-Ethiopia. As a result of the absence of rinderpest disease and the complete suspension of blanket vaccination in the areas regarded as free, the cattle population in major parts of the country have become susceptible to rinderpest. In order to prevent the re-introduction of the disease from the endemic foci, apart from maintaining a sanitary cordon, the Ministry has worked out an emergency preparedness plan to deal swiftly with outbreaks in susceptible cattle populations. 2. Contagious bovine pleuropneumonia Contagious bovine pleuropneumonia (CBPP) seems to be wide-spread in Ethiopia. In lowlands the disease is ranked in high position among the main infectious diseases of cattle since several years. For example, in the Afar region, the climate is semi-arid and the water and grass conditions oblige to adopt extensive cattle breeding systems, which mean constant cattle movements and frequent big herd concentrations at watering points. It is very well known that these two factors are favourable for the spread of CBPP. In addition to that, vaccination campaigns against rinderpest and CBPP in the lowlands were always more difficult and, therefore, less effective than in the highlands. This explains also why the disease has always been important in the lowlands. In the highlands, the consecutive yearly blanket vaccination against rinderpest and CBPP have certainly contained the disease to a relatively low level during the past years. But with the adoption of a new strategy for rinderpest eradication, the vaccinations in the highlands have ceased since 1992-1993. On the other hand, the constant migration of cattle for trade from lowlands to highlands, the transhumance movement of cattle during the dry season from the highlands to the lowlands, facilitate regular contacts between lowlands pastoral cattle and highland sedentary cattle. These circumstances certainly explain the recent increase of the incidence of CBPP in the highlands. Almost all of the 22 woredas of West Wolloga zone were affected by the epizootics by the middle of 1995. The morbidity and mortality rates are difficult to quantify, but according to the field officers they can reach 5 0 % of the herd and 3 0 % to 5 0 % of the sick animals respectively. All cattle owners and field officers agree to say that CBPP come from the lowlands bordering Sudan, in Asosa zone (Benshangul State). According to them, the disease was not known in the highland regions for many years and the herds were infected in Asosa area during the dry season transhumance, from March to June. The occurrence of CBPP in Asosa lowlands is attributed to the presence of nomadic cattle. It appears that CBPP is important all over the country and that a national strategy for its control has to be prepared. Before designing this strategy, a general survey must be carried out, in order to assess the disease situation. A national task force is established in January 1996 to assess the situation of CBPP, to do economical evaluations of the losses due to the disease and to design a control programme. -115- F I N L A N D I.

LIST B DISEASES Diseases of multiple species Rabies No cases of rabies were detected in 1995. The last outbreak was recorded on 16 February 1989. In 1995, in the whole country, the number of suspected animals examined for rabies by immuno-fluorescence on brain tissue was 57, comprising 13 raccoon dogs, 11 foxes, 7 dogs, 16 cats, 1 bovine, 1 brown bear, 1 ermine, 1 rat and 1 bat. All were negative. In an attempt to prevent the reintroduction of rabies, 80,000 Tubingen vaccine baits were distributed, as has been the case since 1988, from the air in September in a zone 20-25-km wide and 250-km long, constituting a land area of 4,000 k m along the south-eastern border of the country. 2 The immune barrier is intended to be maintained by annual vaccination. Diseases of cattle Bulk tank milk survey All the dairy herds in Finland have been examined for brucellosis, infectious bovine rhinotracheitis / infectious pustular vulvovaginitis (IBR/IPV) and enzootic bovine leukosis (EBL) since 1991 using an ELISA test. The number of tested herds in 1995 was 32,588 except for brucellosis where a total of 4,546 samples were examined. Since 1993, testing for bovine virus diarrhoea (FJVD) has also been included. Since 1991, only six herds have been found to be infected with bovine herpesvirus (fBR/TPV). The last positive herd was slaughtered before 1 June 1994. The number of EBL-positive herds detected in 1991, 1992, 1993, 1994 and 1995 was 8, 11, 7, 3 and 1, respectively. These herds have been subjected to official restrictions including slaughter of infected animals. No new EBL-positive herds have been detected in the last surveys. Bovine virus diarrhoea is very rare in Finland. In the survey of dairy herds, 220 herds were found to be positive; of these, 176 had already been found to be positive in the survey of 1994. Voluntary control programmes have been introduced for both EBL and BVD. -116- Suckler cow herds During 1995, a total of 3,787 blood samples from suckler cow herds were collected and 3,640 were examined for brucellosis, IBR/IPV, EBL and BVD. All samples for brucellosis, IBR/IPV and EBL were negative. BVD was detected in 40 herds. Diseases of sheep and goats Caprine and ovine brucellosis (excluding 5. ovis) A total of 6,010 blood samples from 340 different sheep and goat farms were tested for melitensis. All tests were negative. Brucella melitensis has never been recorded in Finland. Brucella Diseases of pigs During 1995, a total of 8,779 blood samples, originating from 5,553 different farms, were collected in slaughterhouses. The samples were collected from all Finnish porcine slaughterhouses. All samples were tested for Aujeszky's disease and transmissible gastroenteritis. A total of 2,684 blood samples were also tested for classical swine fever and 1,678 for swine vesicular disease. All tests were negative. Diseases of poultry A total of 4,554 blood samples from 73 (grand-parent and parent) farms were tested for Newcastle disease. For turkey rhinotracheitis, 3,886 of these samples were also tested. All tests were negative. Vaccination against these diseases has never been allowed in Finland. -117- F R A N C E I.

Maladie vèsiculeuse du porc L'ensemble des sérologies réalisées dans le cadre des exportations se sont révélées négatives. 3. Peste porcine classique Aucun foyer de peste porcine classique chez le porc domestique n'a été confirmé en France en 1995. Le contrôle sérologique de plus de 50 000 reproducteurs en élevage et à l'abattoir a confirmé l'absence de la maladie sur le territoire national et de tout résidu d'anticorps vaccinaux. La vaccination est interdite depuis 1983 sur le territoire métropolitain (hors Corse). Depuis 1993 cette interdiction concerne l'ensemble du territoire national (départements d'outre-mer compris). Le nombre de cas observés chez les sangliers sauvages dans le massif des Vosges a très nettement diminué. L'épidémie reste circonscrite sans extension dans les élevages de porcs de la zone concernée. Par ailleurs, aucune extension au reste du territoire national n'a été constatée lors des contrôles effectués sur les sangliers tués à la chasse. 4. Influenza aviaire hautement pathogène (peste aviaire) Cette maladie, à déclaration obligatoire depuis 1948, est soumise à des mesures de police sanitaire en cas d'apparition. -118- 5. Maladie de Newcastle La maladie de Newcastle est une maladie réputée contagieuse depuis 1948 (autrement dit, elle exige l'application des mesures de police sanitaire, l'abattage indemnisé de tous les animaux dans les foyers et la surveillance des élevages situés dans une zone de 10 km autour des foyers). La vaccination est obligatoire pour les pigeons voyageurs. Elle est largement mise en œuvre dans les élevages de volailles. Le dernier cas de maladie de Newcastle en France métropolitaine date de 1992 ; il concernait des oiseaux d'ornement. En août et septembre 1995, 13 foyers de maladie de Newcastle se sont déclarés dans le département français d'outre-mer de l'île de la Réunion (située dans l'océan Indien à 21° S - 55° 40' E, à l'est de la pointe sud du continent africain). Le diagnostic de maladie de Newcastle dans le premier foyer a été confirmé le 17 août 1995 par le laboratoire national de référence (isolement viral ; indice de pathogénicité intracérébrale du virus : 1.78). Ces 13 foyers regroupaient 49 862 volailles, parmi lesquelles 25 147 sont mortes des suites de la maladie. Les mesures d'éradication conduites dans les foyers ont conduit à la destruction de 24 715 volailles. La vaccination des volailles contre la maladie de Newcastle a été rendue obligatoire sur l'ensemble du territoire de l'île. Toutes les dispositions ont été prises pour, d'une part, restreindre les mouvements de volailles vivantes et d'œufs à couver sur le territoire de l'île, et, d'autre part, interdire la sortie de l'île de tout oiseau vivant et de tout œuf ou viande de volaille. Au 31 décembre 1995, les interdictions de sortie d'oiseaux vivants et la vaccination obligatoire des volailles étaient maintenues. Le fait qu'il n'y ait pas de courant d'exportations de volailles ni d'œufs à couver de l'île de la Réunion vers la France métropolitaine et que tout mouvement soit désormais interdit, permet à la France métropolitaine de conserver son statut indemne de maladie de Newcastle. IL MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Maladie d'Auieszky La lutte contre cette maladie a été rendue obligatoire en France en 1990 sur l'ensemble du territoire national. Elle repose sur un dépistage dont la fréquence est fonction du type d'élevage : - dépistage tous les trois mois pour les élevages vendant des porcs d'élevage (environ 1 000 élevages) ; - dépistage au moins annuel dans les élevages vendant des porcelets destinés à l'engraissement (plus de 20 élevages concernés) ; - dépistage chez les engraisseurs purs selon la situation épidémiologique du département et l'origine des animaux. Une grande partie du territoire présente un très faible taux de prévalence. Vingt et un départements sont actuellement reconnus indemnes par Décision de la Commission européenne. Dans neuf départements, ce taux est plus élevé et conduit à rendre la vaccination obligatoire des reproducteurs et, éventuellement, des porcs d'engraissement, à l'aide de vaccins deletes gE. L'éradication de la maladie d'Aujeszky par dépistage des cheptels infectés et abattage des animaux reconnus infectés se poursuit, notamment dans les départements où la vaccination est obligatoire. -119- 2. Rage L'évolution favorable de la situation épidémiologique de la rage en France s'est encore poursuivie en 1995, pour la sixième année consécutive, ceci grâce à la réalisation régulière de campagnes de vaccination orale des renards.

Maladies des bovins L'élevage bovin français regroupe environ 397 000 cheptels et 15,8 millions de bovins de plus de 1 an, soit une moyenne de 40 animaux par troupeau. 3. Brucellose bovine Applicable dans tous les élevages bovins, le programme de lutte collective contre la brucellose bovine a enregistré des résultats favorables, le nombre de cheptels et d'animaux infectés étant toujours en diminution, même si quelques difficultés demeurent, notamment dans les zones de montagne (Pyrénées et sud du massif Central) à cause des traditions de mouvements de.transhumance. Cependant : 4. - à la fin de l'année 1995, seuls 379 cheptels étaient encore infectés (0,10 %) ; - on note une augmentation de 16 % du nombre d'animaux abattus par rapport à l'année précédente (en 1995, 19 530 bovins ont été éliminés avec indemnisation par l'Etat) témoignant de l'effort entrepris pour éradiquer les derniers foyers. Tuberculose bovine La prophylaxie de la tuberculose en France est obligatoirement réalisée dans tous les cheptels bovins. Désormais, le dépistage des cas est réalisé en premier lieu à l'abattoir (43 % des cas en 1994), mais les contrôles réguliers par tuberculination des animaux demeurent obligatoires, notamment lors des introductions dans les cheptels. Ce programme étant engagé depuis une trentaine d'années, le nombre de cheptels infectés est donc minime : au 31 décembre 1995, 275 cheptels étaient encore infectés (soit 0 , 0 7 % des cheptels). Sur l'année, 4 822 bovins ont été abattus et leurs propriétaires indemnisés par l'Etat. 5. Leucose bovine enzootique Cette maladie fait l'objet d'une lutte collective obligatoire dans tous les élevages bovins depuis 1990. Ainsi, tout dépistage positif impose l'abattage systématique et indemnisé de tous les bovins reconnus infectés. Les cheptels comportant plus de 20 % de bovins atteints sont éliminés dans leur totalité. Au 31 décembre 1995, 738 cheptels demeuraient infectés (- 45 % par rapport à 1994) et 2 284 animaux ont été abattus sur l'ensemble de l'année 1995, soit 29 % de moins qu'en 1994. -120- 6. Encéphalopathie spongiforme bovine Depuis 1991, 13 cas d'encéphalopathie spongiforme bovine ont été confirmés en France, le dernier datant de décembre 1995. L'abattage de tous les bovins de l'exploitation est réalisé dès confirmation du diagnostic et indemnisé par l'Etat. Les carcasses des bovins abattus sont transformées en farine à l'équarrissage et ces farines sont incinérées. Répartition des cas d'encéphalopathie 1991 5 cas 1992 0 cas 1993 1 cas spongiforme bovine en France 1994 4 cas 1995 3 cas Malgré une très faible incidence de la maladie, la France s'est dotée d'un réseau national d'épidémiosurveillance spécifique, relayé dans chaque département par un vétérinaire praticien spécialement formé à cet effet. Il y a donc une surveillance systématique des maladies nerveuses dans les élevages et les abattoirs. Enfin, dès 1990 l'utilisation des farines de viande et d'os de ruminants a été interdite en France pour l'alimentation des ruminants. Maladies des ovins et caprins L'élevage français regroupe environ 150 000 cheptels ovins ou caprins comprenant environ 7,7 millions d'ovins et 930 000 caprins de plus de six mois. 7. Brucellose caprine et ovine (non due à B. ovis) La lutte contre la brucellose ovine et caprine est obligatoire dans tous les cheptels. L'infection reste localisée dans le sud du pays (région Provence-Alpes-Côte d'Azur-Corse et Pyrénées). Le nombre de cheptels infectés au 31 décembre 1995 n'était que de 849 (soit 0,6 % des cheptels français). Ces résultats sont dus en grande partie à un dépistage régulier des élevages et à l'abattage systématique et indemnisé de tous les animaux atteints. Maladies des équidés 8. Métrite contagieuse équine Depuis 1981, la métrite contagieuse équine est une maladie à déclaration obligatoire, et depuis 1992 elle est inscrite à la nomenclature des maladies réputées contagieuses et donne lieu à l'application de mesures de police sanitaire dès la mise en évidence du germe, même en l'absence de signes cliniques (traitement des animaux infectés et contrôle des contaminés). Le dépistage est obligatoire pour tous les étalons agréés à la monte publique, ainsi que pour toutes les juments inscrites au programme de lutte contre cette maladie (programme facultatif et subventionné par l'Etat). En 1995, 3 928 étalons et 22 500 juments ont été contrôlés. Parmi ces animaux, 15 étalons et 17 juments ont été reconnus infectés. Par rapport à 1994, le pourcentage d'animaux infectés a baissé de 47 % pour les étalons et de 70 % pour les juments. Cette baisse témoigne d'une évolution favorable de la situation de la métrite contagieuse équine en France. 9. Anémie infectieuse des équidés Dès 1976, les équidés présentant des signes cliniques d'anémie infectieuse des équidés confirmés par analyse de laboratoire ont fait l'objet de mesures d'abattage sanitaire. Depuis 1992, tout test de Coggins positif entraîne l'abattage des équidés concernés et une enquête épidémiologique et sérologique est mise en œuvre dans le foyer et dans les élevages ayant des liens épidémiologiques avec le foyer, pour dépister les animaux contaminés. L'assainissement est poursuivi dans les foyers jusqu'à obtention des deux résultats sérologiques négatifs à trois mois d'intervalle sur l'ensemble de l'effectif. -121 - Aucun foyer n'a été à déplorer en 1995. Les 10 foyers recensés en 1994 ont été assainis, 9 en 1994 et 1 au début de l'année 1995. Maladies des 10. volailles Salmonelloses et mycoplasmose (M. gallisepticum) Depuis 1982, la France a mis en place des mesures de lutte contre les contaminations à Salmonella gallinarum pullorum et S. arizonae (chez la dinde) et certains mycoplasmes dans les établissements d'accouvaison. Le recensement de cas dans les filières "dinde", "poulet" et "canard" reste exceptionnel. Maladies des poissons 11. Septicémie hémorragique virale Cette maladie est à déclaration obligatoire en France depuis 1985 et des mesures de police sanitaire sont appliquées dans les foyers. 12. Nécrose hématopoïétique infectieuse Cette maladie est à déclaration obligatoire en France depuis 1985 ; en cas d'apparition d'un foyer de nécrose hématopoïétique infectieuse, des mesures réglementaires de police sanitaire sont appliquées pour éradiquer la maladie. En 1995, deux foyers de nécrose hématopoïétique infectieuse ont été déclarés et assainis. III. AUTRES MALADIES Salmonellose aviaire (à l'exception de S. gallinarum et S. pullorum) Un contrôle hygiénique et sanitaire a été organisé en filière "ponte d'œufs de consommation". A tous les niveaux de la filière les éleveurs appliquent un programme de dépistage de Salmonella enteriüdis. Les troupeaux infectés sont abattus avec l'aide financière de l'Etat. - 122- G R E E C E LIST A DISEASES General overview Disease present in 1995 Total 1994 1 Sheep pox and goat pox Diseases never Total 1995 9 Jan 0 Diseases reported absent in 1995 (in parentheses: and and and and and mouth mouth mouth mouth mouth Mar 0 Apr 0 May 0 1995 Jun Jul Aug Sep Oct Nov 0 0 0 0 4 5 0 F.P.

Diagnosis was set by AGID and seroneutralisatin test, and confirmed by virus isolation in sensitive cell culture. Measures were taken in accordance with EU recommendations, including stamping out and refraining from vaccination. Epidemiological inquiry in the infected herds has indicated that the disease invaded independently Evros and Thessaloniki through personnel movements from neighbouring countries. 11-94 -123- G R E E N L A N D INTRODUCTION With regard to veterinary matters, the responsibilities are divided between the Greenlandic Health Authorities and the Danish Veterinary Services under the Ministry for Agriculture and Fisheries. Matters relating to the zoo-sanitary situation in Greenland and the inspection of meat for export are the responsibility of the Danish Veterinary Services while the Greenlandic Health Authorities are responsible for control of foodstuffs and zoonotic diseases including the control of rabies. I. LIST A DISEASES No List A diseases have ever been reported in Greenland. II. LIST B DISEASES 1. Rabies Rabies is considered endemic among arctic foxes (Alopex lagopus), especially in the northwestern districts of Greenland (Sisimiut to Avanersuaq). During the period 1975-1995 a total of 506 foxes, 428 dogs, 7 sheep, 4 cats, 3 reindeer, 1 musk ox (Ovibos moschatus), and 1 wolf were ewamined for rabies at the National Veterinary Laboratory, Copenhagen, Denmark and the State Veterinary Institute for Virus Research, Lindholm. Denmark (since 1990). In 1995, a total of 30 animals were examined, consisting of 29 foxes and 1 dog. Rabies was diagnosed in 6 foxes (21%). Twenty of the foxes examined were in connection with the rabies surveillance programme carried out by the Greenland Ministry of Health and Environment. Of these foxes, 5 (25%) were found positive. The other positive case was found from a group of 10 foxes killed in July near Thule Air Base and examined for rabies virus prior to the start of a pilot project involving oral vaccination of foxes with rabies vaccine. All positive rabies cases in 1995 were located in northern Greenland (Thule [Qaanaaq], Upernavik and Station Nord/east coast) and Qaqortoq county in southern Greenland. Although no cases of rabies were diagnosed in the sheep farming areas of southern Greenland in 1995, the disease was still present in these areas as shown by the three positive cases in foxes from the town of Qaqortoq in March and April. 2. Equine rhinopneumonitis Serological examinations carried out in November on serum from eight horses revealed one seropositive horse. Clinical signs have not been recorded. 3. Trichinellosis The disease has been recorded among polar bears (Thalarctos maritimus), arctic foxes, walruses (Odobenus rosmarus) and sledgedogs. The disease has not been recorded in sheep, reindeer or musk ox. -124- Rabies positive cases diagnosed in Greenland during the period 1975 - 1995 * Sledgedog districts Holsteinsborg / Sisimiut Egedesminde / Aasiaat Christiansháb / Qasigiannguit Jakobshavn / Ilulissat Godhavn / Qeqertarsuaq Umaiiak / Uuinmanaq Upernavik Thule / Qaanaaq Ammassalik / Tasiilaq Scoresbysund / Ittoqqortoormiit Station Nord Total Non-sledgedog districts* Nanortalik Julianeháb / Qaqortoq Narsaq Frederiksháb / Paamiut Godtháb / Nuuk Sukkertoppen / Maniitsoq Total Rabies vaccination Sledgedog districts Dogs Foxes 7 0 9 6 0 20 5 11 0 5 1 29 9 4 7 1 0 24 47 2 7 3 64 133 Dogs Foxes 0 0 1 0 0 0 8 7 3 0 11 2 0 6(sheep) 0 0 1 (reindeer) 0 1 31 7 Other animals of dogs in Greenland in 1995** Estimated No. of dogs No. of dogs vaccinated Holsteinsborg / Sisimiut Kangaatsiaq Egedesminde / Aasiaat Christiansháb / Qasigiannguit Jakobshavn / Ilulissat Godhavn / Qeqertarsuaq Umanak / Uummanaq Upernavik Avanersuaq Ammassalik / Tasiilaq Scoresbysund / Ittoqqortoormiit Sirus Patrol Sondrestrom / Kangerlussuaq 1,872 1,762 2,220 1,601 8,262 1,283 5,577 4,867 1,563 2,622 600 77 62 631 769 1,124 140 742 438 2,085 2,840 445 525 111 75 0 Total sledgedogs 32,368 10,490 Non-sledgedog districts Estimated No. of dogs Nanortalik Julianeháb / Qaqortoq Narsaq Frederiksháb / Paamiut Gronnedal / Ivittuut Godtháb / Nuuk Sukkertoppen / Maniitsoq Total No. of dogs of various breeds vaccinated 18 87 27 0 10 80 48 900 270 Sledgedogs are found exclusively in the sledgedog districts in eastern and north-western Greenland.

LIST B DISEASES Diseases of multiple 1. species Heartwater Surveillance conducted in 1993 indicated the presence of serological evidence of the disease in Carriacou and not on the mainland of Grenada. No clinical cases have been recorded. Continuous surveillance has not recorded the presence of the Ambly<omma tick in Grenada. 2. Leptospirosis Leptospirosis is present in dogs primarily. A few cases have occurred in cattle. The serotype and incidence are not known. -126- The diagnosis of affected animals is made based on clinical signs noted during medical examination procedures. Our current laboratories do not have the resources to confirm this disease. 3. Rabies Rabies is endemic in Grenada. Mongoose is the vector of the disease to the livestock population. Sporadic cases occur on a monthly basis. A functional Rabies Laboratory is in existence with the Ministry of Health. There are trained technicians in the Laboratory who are capable of preparing specimens for identification of the virus. Rabies immunisation campaign is being conducted yearly in conjunction with the Ministry of Health. In 1995, livestock pets and domestic animals were vaccinated throughout the entire island. Diseases of cattle 4. Bovine anaplasmosis Anaplasmosis can be considered endemic in Grenada. Sporadic occurrences appear among cattle every year. Prevalence rate among cattle is 0 . 1 % . Anaplasma marginale is the agent frequently diagnosed among cattle. Boophilus tick is one of the main transmitters in Grenada. 5. Bovine babesiosis Babesiosis is seen in cattle mainly in Grenada. This disease is not as prevalent as anaplamosis. Only on rare occasions one or two cases will occur. Diseases of sheep and goats 6. Brucellosis There is serological evidence of brucellosis in sheep. No clinical cases are recorded. Surveillance conducted together with the PAHO representative for the region in 1993 did not disclose any clinical case. Also ongoing surveillance fails to record any clinical case. 7. Caprine arthritis/encephalitis Surveillance conducted in 1992 and 1994 disclosed serological evidence of the disease. No clinical cases have been recorded. Continuous surveillance in 1995 failed to disclose clinical evidence of the disease in Grenada. -127- G U I N É E I.

Influenza aviaire hautement pathogène sur certaines maladies de la Liste A Peste bovine Les mesures conservatoires prises dans les années 1964-1965 sous la forme de barrière vaccinale aux frontières avec le Sénégal et le Mali (sur 70-80 km de profondeur), ont été renforcées de 1988 à 1994 à travers le projet de restructuration du secteur de l'élevage. En 1995 il n'y a pas eu de vaccination. 2. Peste des petits ruminants La vaccination annuelle a été organisée à partir du deuxième trimestre de l'année 1995. Pour l'année 1995, il a été enregistré 1 544 animaux malades et 737 morts. 3. Péripneumonie contagieuse bovine La péripneumonie contagieuse bovine sévit à l'état enzootique depuis 1936 dans la zone Est du pays. Sa propagation à l'ouest a été freinée par l'établissement d'un cordon sanitaire qui a limité les courants commerciaux entre la zone saine et la zone contaminée. Une vaccination massive a été menée dans la zone infectée, pendant le deuxième semestre de 1995. Au cours de cette campagne de vaccination, les animaux cliniquement atteints ont été abattus sans indemnisation des propriétaires. En 1995, deux foyers ont été enregistrés dans la zone indemne, dans deux villages de la préfecture de Mamou limitrophes de la zone infectée. Tous les animaux des parcs affectés ont été abattus. Une vaccination obligatoire autour des foyers a été réalisée, suivie d'un contrôle sérologique et de l'abattage des animaux séropositifs, sans indemnisation des propriétaires. En 1995, en Guinée, il a été enregistré 122 animaux malades et 79 morts. -128- 4. Dermatose nodulaire contagieuse La dermatose nodulaire contagieuse a été signalée pour la première fois en Guinée en 1994 et confirmée en janvier 1995 par le CfRAD-ENTVT. Une vaccination étendue sur l'ensemble du pays a été réalisée comme suit : - le croît du troupeau (jeunes nés après l'épidémie de 1994) dans les préfectures où l'épidémie a été signalée ; - les bovins de tout âge dans les zones où l'infection n'a pas été signalée. Des sérums ont été prélevés trois à quatre semaines avant et après la vaccination pour l'évaluation de la campagne. Au cours de l'année 1995, 103 foyers ont été enregistrés, avec 1 136 animaux malades et 15 morts. II. MALADIES DE LA LISTE B Rage L'abattage des carnivores errants a été organisé dans les grands centres urbains. En 1995, il a été signalé 18 cas de rage canine dans la capitale et à l'intérieur du pays. m. AUTRES MALADIES Charbon svmptomatique En 1995, 130 foyers de charbon symptomatique ont été signalés, avec 836 animaux malades et 430 morts. -129- G U Y A N A INTRODUCTION Diagnostic work is not being executed in Guyana presently (apart from an ongoing trypanosome survey which is being carried out in collaboration with French Guiana and Suriname): small animal (pet animals) disease diagnosis is done with the assistance of the human laboratories.

Certes, pour certaines maladies, telles la rage et la fièvre charbonneuse, on a noté une incidence beaucoup plus forte due au fait que les programmes mis sur pied avaient pris du temps pour démarrer. Par ailleurs, dans le but d'harmoniser la réglementation sanitaire nationale avec les normes internationales, un projet de "Lois et Règlements sur la Santé Animale" a été préparé par les services techniques compétents (l'Unité de Protection Sanitaire du ministère de l'agriculture, des ressources naturelles et du développement rural) et soumis à l'Assemblée nationale pour suites nécessaires.

Fièvre charbonneuse La fièvre charbonneuse a connu en 1995 une ampleur jusque là jamais enregistrée. Ceci est surtout dû à la dégradation accélérée du milieu et au manque d'information de la population (voir tableau A). Une campagne nationale de vaccination anticharbonneuse a été financée par le ministère de l'agriculture (voir tableau B). Une campagne de déparasitage interne et externe a été exécutée à cette occasion. 2. Rage En 1995, quatre cas de mortalité ont été enregistrés dans le département du Sud, contre trois cas de rage diagnostiqués chez des chiens dans ce même département. Dans le département de l'Ouest, deux cas de rage humaine ont également été enregistrés. Un plan national de lutte contre la rage a été élaboré, mais le financement n'est pas encore disponible. En marge de ce plan, une campagne de vaccination concentrée autour des villes a été réalisée avec les concours matériel et logistique de la mission des Nations Unies en Haïti (voir tableau C). -131 - A.- Résultats d'une enquête épidémiologique sur la fièvre charbonneuse a Cas chez l'homme ( ) Département Artibonite Centre Grand' Anse Nord Nord-Est Nord-Ouest Ouest Sud Sud-Est Total en Haïti Cas chez l'animal 0 4 99 24 0 12 0 56 254 0 23 16 14 28 10 0 334 342 449 767 ^ (a) Informations recueillies au niveau des hôpitaux et des centres de santé et concernant des patients présentés pour traitement.

Newcastle disease For all susceptible poultry species we adapt vaccines, having a low pathogenicity index, authorized by the EU and prepared from lentogenic strains, for all growing poultry stock (broilers, layers and breeding stock). II. LIST B DISEASES Diseases of multiple 1. species Rabies In the western part of Hungary, along the Austrian border, over an increasingly wide area, we have continued oral immunisation of foxes against rabies since the autumn of 1992. From the start, we have used the aerial distribution method with a Global Positioning System (GPS) and computer registration. We are satisfied with this method and its results and we intend to free the entire area of the western part of Hungary bordered by the Danube from rabies as soon as possible. 2 From the autumn of 1996, we will carry on immunisation over a minimum area of 22,000 km . The extension of vaccination to the whole country is only prevented by lack of finance. -133- Diseases of cattle 2. Bovine brucellosis and tuberculosis Hungary has retained its status of freedom from tuberculosis and brucellosis. There were occurrences of tuberculosis in 1994, originating from infected people living and taking jobs temporarily in Hungary because of the Balkan wars who could not be controlled by the public health authorities. Diseases of poultry 3.

In October 1995, the Government of India declared the States of Arunachal Pradesh, Assam, Nagaland, Manipur, Meghalaya, Mizoram and Tripura in the north-eastern zone, Bihar, Delhi, Gujarat, Haryana, Himachal Pradesh, Jammu and Kashmir, Madhya Pradesh, Orissa, Punjab, Rajasthan, Sikkim, Uttar Pradesh and West Bengal in the indo-gangetic zone provisionally free from rinderpest with effect from June 1994. In the southern zone a few cases of the disease were reported in the States of Karnataka and Tamil Nadu. It was not reported in Maharashtra, Goa, Kerala and Andhra Pradesh. 2. Peste des petits ruminants Peste des petits ruminants was reported first time in the States of Himachal Pradesh and West Bengal, and the disease was confirmed. 3. Contagious bovine pleuropneumonia There was no incidence of contagious bovine pleuropneumonia in any part of the country. II. LIST B DISEASES Equine infectious anaemia Equine infectious anaemia was reported only from one district in the State of Punjab. The remaining parts of the country remained free from equine infectious anaemia. -135 - I N D O N E S I A INTRODUCTION Most animal health activities are conducted by the government, particularly for small farmers. However, the private sector is now taking a bigger role in animal health activities. In certain areas, the concept of paying for services is beginning to be introduced under which farmers themselves pay for animal health services provided by animal health posts. Among the 226 animal diseases in the world, there are 87 animal diseases present in the country, including 33 viral, 29 bacterial and 25 parasitic diseases. Of these 87 diseases, 43 are regarded as 'economic' diseases and the rest (44 diseases) have not been reported for many years. Among the 43 diseases of economic importance, 14 are considered as 'strategic' diseases: anthrax, haemorrhagic septicaemia, brucellosis, rabies, trypanosomiasis, malignant catarrhal fever, Jembrana disease, Newcastle disease, anaplasmosis, babesiosis, leptospirosis, tuberculosis and infectious bursal disease.

A control programme is conducted through sanitation and vaccination. The vaccine used is subsidised by the government. The disease is not a problem for commercial poultry since maximum security measures are applied to provide protection from the disease. II. LIST B DISEASES Ten diseases in OIE List B were recorded in Indonesia: anthrax, haemorrhagic septicaemia, brucellosis, rabies, trypanosomiasis, malignant catarrhal fever, anaplasmosis, babesiosis, infectious bovine rhinotracheitis and infectious bursal disease (Gumboro disease). -136- 1. Anthrax Anthrax is mainly reported sporadically in eastern areas of the country. Control of the disease is implemented through strict regulation of livestock movement, especially from infected to free areas. A vaccination programme is also implemented to control the disease. Sick animals are treated using anti­ serum combined with antibiotics. 2. Rabies The provinces of Bali, West Nusa Tenggara, East Nusa Tenggara, East Timor, Maluku and Irian Jaya are continuing to be rabies-free zones. An intensive control programme against rabies concentrated in Java and Kalimantan was implemented for five years from 1989 (1989-1993) and a control programme for Sumatera and Sulawesi has been in place since 1993. Elimination of stray dogs and a mass vaccination campaign are still being carried out. An inter-departmental action has been initiated and has proved to be very effective in the implementation of the rabies control programme. Diseases of cattle 3. Bovine anaplasmosis Anaplasmosis can be found sporadically throughout Indonesia, especially in cattle and buffalo. The control programme against this disease is through prevention by artificial immunisation, and control and eradication through sanitation and isolation of sick animals. 4. Bovine babesiosis Babesiosis can also be found sporadically throughout Indonesia, especially in cattle and buffalo. The control programme for this disease is similar to that for anaplasmosis. 5. Brucellosis Brucellosis is reported in most provinces with different levels of prevalence. Bali and Madura are the only islands free from brucellosis. A low prevalence of brucellosis is reported in the transmigration areas and among dairy cattle in Java. Control policy is based on preventive action, control and eradication. Preventive action is based on sanitation and hygiene and strict controls on livestock movement. Control and eradication programmes are based on a serological test, vaccination for heifers, and test and slaughter. 6. Haemorrhagic septicaemia Haemorrhagic septicaemia is one of the most economically important enzootic diseases of draught large ruminants in Indonesia. The disease has spread throughout almost all the country. Preparation for a progressive haemorrhagic septicaemia eradication programme has been launched in the eastern part of Indonesia. The control programme is based on prevention, control, eradication and treatment. Preventive action is based on strict importation to free areas, and vaccination. The control and eradication programme is conducted by isolation of sick animals and other technical actions. Treatment involves the use of anti-serum or antibiotic. 7. Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis Infectious bovine rhinotracheitis is found in the provinces of South Sulawesi, North Sumatera, Riau, Bali and South Kalimantan. The control programme is based on a ban on importation from infected areas, strict quarantine and vaccination, using killed vaccine for areas where the disease is enzootic. 8. Trypanosomiasis Trypanosomiasis is the most important blood parasitosis in Indonesia. Preventive action involves the use of naganol and sanitation of the environment, while the control programme is conducted through isolation of sick animals and control of vectors in areas which are most frequently infected. -137- 9. Malignant catarrhal fever Malignant catarrhal fever occurs sporadically with low incidence in Indonesia. The disease is associated with sheep-keeping. It is suspected that goats could be the host of the malignant catarrhal fever virus. Diseases of poultry 10. Infectious bursal disease (Gumboro disease) Gumboro disease is found sporadically in Sumatra, Java, Kalimantan and Sulawesi. At present, about 17 local strains have been successfully isolated and three strains are being used to produce vaccines which it is hoped will afford protection from Gumboro disease in Indonesia. Control of Gumboro disease is the most important action in order to prevent the spread of the disease, since an effective treatment for the disease has not yet been found. The control programme for Gumboro disease includes the control of movements of poultry and humans, sanitation and hygiene care of cages and the environment, and vaccination. Sanitation and hygiene care of cages and the environment are conducted by using a disinfectant which is effective against Gumboro disease virus, by using the all-in all-out system in broiler farms and by preventing stress. The vaccination programme is different for breeders / layers and for broilers. Vaccination in breeders and layers is conducted three times (initial, booster and preliminary), while vaccination in broiler is conducted twice (initial and booster). III. OTHER DISEASES 1. Bovine ephemeral fever Bovine ephemeral fever exists in Java, Bengkulu, East Kalimantan, West Irian, Maluku Island, East Nusa Tenggara. The control programme is through elimination of vectors and isolation of sick animals, while treatment of sick animals can be tried using a broad spectrum of antibiotics to eliminate secondary infection. 2. Mucosal disease / bovine virus diarrhoea An outbreak of bovine virus diarrhoea erupted in 1989-1990 in the provinces of Bali, West Nusa Tenggara, East Java, South Sulawesi, East Kalimantan, Bengkulu, Riau and South East Sulawesi, North Sulawesi, Lampung and South Kalimantan. The last cases occurred in Bali and South Sulawesi. The control programme is through sanitation and isolation of sick animals, control of importation and stamping out for areas which have never previously been infected. 3. Jembrana Jembrana is a disease that was originally found in Indonesia and is considered as 'strategic'. Jembrana disease was first reported in 1964. The disease attacks only Bali cattle and causes high mortality. The causal agent is a virus of the family Retroviridae and the Subfamily Lentivirinae. The disease causes immunodeficiency or immunosuppression. At present, a conventional method using inactivated Jembrana virus obtained from blood plasma and spleen of infected cattle has been developed to produce vaccine against the disease. Trial vaccination using this vaccine has been conducted in West Sumatra and has given satisfactory results. Further research using a tissue culture method is also in progress. Control of the disease is implemented through isolation of sick animals and deep burial of the carcases of dead animals. Elimination of vectors is also an important factor for controlling the spread of the disease. In 1995, there were 212 cases of Jembrana disease. -138 - I R A N INTRODUCTION In 1995, the veterinary organisation increased its activities regarding prevention and control of animal diseases as well as eradication of certain diseases.

Rabies Rabies was reported from the entire country in domestic and wild animals, such as: dog, cattle, sheep, goats, wolves, cats, foxes, jackals, donkeys, horses, mules, camels, raccoons, wild pigs, jacks and monkeys. Control measures are based on: - vaccination of 106,000 dogs and cats; - condemnation of stray dogs and bitten animals. Diseases of cattle 3. Bovine babesiosis Babesiosis is enzootic in Iran and was reported in cattle, sheep and goats in 1995. Control measures are based on: - anti-tick dipping; - 4. spraying of premises. Bovine brucellosis Under the national programme against brucellosis, disease control measures were based on: - vaccination of 568,300 calves (3 to 6 months of age) with strain 19; - serological testing of 724,396 dairy cows, of which 4,764 were slaughtered; - control of animal movements; - disinfection of contaminated premises. -140 - 5. Bovine tuberculosis Under the national eradication programme, a total of 1,160,681 cattle were tested. Of these, 3,022 cattle were positive and were slaughtered. 6. Haemorrhagic septicaemia Sporadic cases of haemorrhagic septicaemia occurred in northern and north-western parts of the country. 7. Theileriosis Control measures in 1995 were based on: - anti-tick dipping; spraying of premises; - vaccination of 237,000 cattle and 204,000 sheep and goats. Diseases of sheep and goats 8. Caprine and ovine brucellosis (excluding B. ovis) In 1995, the national programme against brucellosis in sheep and goats included the following control measures: - 9. mass vaccination of 3,878,948 small ruminants (4 to 6 months of age); testing limited to flocks which reported positive from human brucellosis sources. A total of 502,620 animals were tested and 16,890 were positive. Contagious agalactia Contagious agalactia was reported from most parts of the country. 10. Contagious caprine pleuropneumonia Contagious caprine pleuropneumonia was mainly reported from goat-raising parts of the country. Diseases of poultry 11. Avian infectious bronchitis Infectious bronchitis is reported in most parts of the country, we are using killed vaccine at the first week of age in mothers, and a good titre is obtained after 27 days. Day-old chicks also receive vaccine. 12. Infectious bursal disease (Gumboro disease) Under the programme, we are using intermediate 13. vaccine in mothers at 18 weeks of age with good results. Marek's disease Under the programme, layer day-old chicks will receive turkey herpesvirus vaccine and grand-parents will receive Rispense vaccine. -141 - I R A Q INTRODUCTION During the years 1994-1995, the various institutes and veterinary hospitals offered their services to control and prevent infectious and parasitic diseases of animals and to safeguard human health from zoonoses. To summarise the situation, it should be noted that the economic blockade covered veterinary drugs and vaccines as well as laboratory equipment and materials, and the main veterinary laboratories in Baghdad especially that laboratories producing foot and mouth disease (FMD) vaccines. Veterinary laboratories The main laboratory producing FMD vaccines, built by France, was closed by the United Nations. Other laboratories are in a difficult situation, with no equipment or materials, and reduced staffing levels. We are requesting support and assistance to deal with the situation by supplying vaccine materials and retraining staff. I. LIST A DISEASES 1. Foot and mouth disease A high number of cases of FMD were recorded in various areas in cattle and sheep. No vaccine is available because the main laboratory producing FMD vaccine was closed by the United Nations. 2. Rinderpest No cases of rinderpest were recorded. The regular continuing campaign to vaccinate animals has been carried out annually without a successful result. 3. Newcastle disease Newcastle disease was recorded in vaccinated farms. II. LIST B DISEASES Diseases of multiple 1. species Rabies Many cases of rabies were recorded in humans. Efforts to prevent incidence of rabies and hydatid diseases were continued. There is currently no rabies vaccine available. 2. Brucellosis A survey of brucellosis has shown that the disease is continuing to cause high losses, including economic losses from animal abortion. Many human cases have been recorded. The survey of brucellosis and tuberculosis is still operating and a special Brucella Centre was established to coordinate activities. A Brucella vaccine programme is planned. -142- Diseases of cattle 3. Bovine babesiosis, thcilcriosis and trypanosomiasis Theileriosis, babesiosis and tripanosomiasis were recorded. Foreign and cross-bred cattle are more susceptible to Theileria. It is difficult to prepare a vaccine against theileriosis because of the shortage in equipment and laboratory materials. 4. Haemorrhagic septicaemia Sporadic cases were reported. Diseases of poultry 5. Infectious bursal disease (Gumboro disease) Gumboro disease was recorded in vaccinated farms. III. OTHER DISEASES Cases of salmonellosis were recorded. Sporadic cases of blackleg were reported. The rapid spread of three-day sickness in spring was halted by treatment. Ectoparasites Dipping and spraying were conducted. Tick resistance to medicine is very high. Endoparasites Treatment was given to eliminate and reduce the risk of endoparasites. -143- I R E L A N D INTRODUCTION In 1995, national surveillance programmes for equine viral arteritis, enzootic bovine leukosis, maedi-visna, porcine reproductive and respiratory syndrome, transmissible gastroenteritis, Brucella ovis, B. melitensis, B. suis, Mycoplasma agalactiae, caprine arthritis/encephalitis and warble fly were carried out. One goat was seropositive for caprine arthritis/encephalitis and one imported calf was seropositive for enzootic bovine leukosis although no virus could be isolated in either instance. Nevertheless, control measures were instituted in both situations. All the other results of the surveillance programmes were negative and Ireland maintained its freedom from these diseases. I.

LIST B DISEASES Diseases of cattle 1. Bovine spongiform encephalopathy There were 16 cases of bovine spongiform encephalopathy confirmed in 1995. All were in different herds and involved cows 4 years of age or older. All herds with a confirmed case continue to be depopulated under the voluntary scheme introduced in 1989 to facilitate trade and export certification. Diseases of 2. lagomorphs Viral haemorrhagic disease of rabbits In November 1995, viral haemorrhagic disease of rabbits was confirmed for the first time in Ireland. The first confirmed outbreak occurred in County Meath in a group of 13 pet rabbits. -144- I S R A E L INTRODUCTION During 1995, the agreement the establishment of Palestinian Autonomy was gradually implemented with the consequent steps in coordinated veterinary activities, including periodic meetings of the bilateral veterinary committee. Towards the end of the year, the Agricultural Agreement between Jordan and Israel was signed by the two ministers. This Agreement, which includes significant veterinary clauses, is to be further discussed with a view to implementation in 1996. The Trinational Animal Health Research Project (TAHRP), a five-year programme sponsored by the US Agency for International Development (USAID) within the Middle East Regional Cooperation (MERC) programme, was terminated towards the end of 1995. Its fourth and last annual symposium was held in Tiberias, Israel, from 23 to 27 April. In addition to 49 TAHRP participants from the three countries (Egypt, Israel, United States of America) and the Steering Committee members, the symposium was attended by the Chief Veterinary Officers (CVOs) of Jordan and the Palestinian Authority, as well as US, Palestinian and European experts and representatives of USAID, EU, FAO, WHO and OIE. On the last day of this conference, a plenary session on "animal health in the Middle East and opportunities for cooperation" was held in the Gabriel House in Zemach. In addition to Egypt and Israel, it included contributions from the Palestinians, Jordanians and four international organisations who expressed strong support for the extension of the project. In order to enhance regional cooperation, the CVOs of Egypt, Israel, Jordan and the Palestinian Authority met later during 1995 in Paris and Cairo and concluded their mutual proposals for regional veterinary projects involving the four parties with special emphasis upon the improvement of diagnostic facilities in the Palestinian Autonomy and development of its veterinary infrastructure and control programmes, and upon the early development of a regional veterinary information system. These proposals have been forwarded to the USAID MERC as well as to the European Union. The European Union designated a specialist to enhance the planning and follow-up. The implementation of approved proposals will be directed by a 'Regional Oversight Council' (ROC), composed by the four CVOs. The pilot Brucella melitensis control programme in four districts, which was terminated during 1994, was followed by a general country-wide project, beginning 1 April 1995. Several legislative activities took place during 1995, of which the most significant was the approval by the Knesset (Parliament) of a modification to the Animal Disease Ordinance (1985). According to this modification, the Veterinary Services and Animal Health (VSAH) were granted authority 'to prescribe and regulate any examination, treatment, disinfection, seizure, transfer, detainment, removal, killing or destruction of animals, animal products or carcasses, due to which the risk of damage to the health of human beings exists'. Until recently, the VSAH were authorised to act only in regard to animal health as their main subject of concern. Other new regulations, published during 1995, related to the licensing of and control over grading stations for table eggs, to the control over biological and chemical residues in poultry meat and to the prohibition on the feeding of lactating animals with recycled poultry manure as well as prescribing its pre-slaughter withdrawal periods from the feed of non-lactating food animals. In April 1995, Dr Jean Blancou, Director General of the OIE, paid his first visit to Israel. His conclusions, summarised in a letter of 19 April, included inter alia his appreciation for TAHRP and an expression of the readiness of the OIE to actively participate in the extended project, as well as his recommendation to include other countries in the region which want to participate in such projects. -145- I.

All were caused by FMD virus type O j . The routine laboratory techniques applied by the Kimron Veterinary Institute (KVI, Beit-Dagan) for FMD diagnosis and virus identification are the complement fixation test, ELISA, PCR, isolation in PK or LK cells, seroneutralisation and inoculation into baby mice. Genetic analysis is also routinely carried out" by elucidating the sequence of 292 bases (320-613) of the VP1 genes. It was found that 4 of the isolates were genetically very closely related (rate of mutation of less than 5%); their relationship to isolates from neighbouring countries will hopefully be studied in the future. Based upon the antigenic analysis of the isolates, the vaccine used included FMD virus serotypes O Manisa and O Geshur. Not one of the dairy farms of the country was affected, reflecting the severe animal movement restrictions imposed and the impact of vaccination. The effectiveness of the vaccine used was also confirmed by the ongoing monitoring programme, which has been operational since 1992. It includes six farms with cattle of Israeli-Holstein breed, scattered throughout the country and along the borders. On each farm, 40 animals in four age-groups are sampled three times a year for an SNT evaluation of their immunity, conferred by the trivalent vaccine. The FMD virus types used in the SNT are strains of A , O and Asia 1, from the region, as current as possible. 2 2 In 1995, a total of 472,513 vaccinations of cattle with the trivalent vaccine were carried out. as well as 392,630 monovalent (O) vaccinations in small ruminants. The figures for 1994, when 19 foci were recorded with consequent revaccinations around them, were 511,845 and 418,744 respectively. Vaccinations are liable to State fees, paid by the owners. The present policy of the VSAH is to vaccinate annually all cattle above the age of 3 months during October to December. Booster vaccination is carried out in cattle younger than 18 months, 8 to 12 weeks after their initial vaccination. Calves born after the general vaccination period are vaccinated when 3 months old within a secondary scheme. Vaccination involves also the entire sheep and goat population. Cattle are vaccinated with a trivalent vaccine including types O (Manisa and Geshur), A and Asia 1. Small ruminants are currently vaccinated with a monovalent vaccine O (Manisa and Geshur). In the event of an outbreak, revaccinations are carried out in the surrounding area, in addition to all the quarantine and animal movement restrictions prescribed by law. 2 2 07-94 11-94 -146- 2. Peste des petits ruminants This disease, diagnosed for the first time in Israel in 1993, have not been reported in Israel since. General vaccination in sheep and goats was continued during 1995; more than 200,000 vaccinations were carried out. 3. Bluetongue The annual bluetongue season in Israel is July to December, the peak months being October and November. Compared to the 1993 and 1994 seasons, which were characterised by extensive incidence of the disease caused by bluetongue virus (BTV) type 16, which had not been involved in field cases of bluetongue in Israel since 1975, only seven outbreaks were reported during 1995, six of which were due to BTV type 16 and one to BTV type 4. All were reported in unvaccinated young sheep of exotic (European) breeds and their crosses. PCR was added in 1995 to the traditional laboratory B T V identification techniques used by the KVI. In 1995, a pentavalent bluetongue vaccine was put into use, including type 16, in addition to the traditionally used BTV types 2, 4, 6 and 10. Type 16 was recently attenuated by the Onderstepoort Vaccine Laboratory (South Africa) and added to the quadrivalent vaccine after completion of protection trials -for which the VSAH are very grateful. 4. Sheep pox No cases of sheep pox were reported in 1995, compared to none in 1994 and five in 1993. Consequently, a further drop in the number of vaccinations was observed: only 36,291 in 1995 compared to 48,805 during 1994 and 232,761 in 1993. II. LIST B DISEASES Diseases of multiple 1. species Rabies In 1995, 55 cases of rabies were diagnosed by the KVI, compared to 85 in 1994 and 70 in 1993. The disease maintained its sylvatic nature. Cases were observed in most districts, with the highest densities in the areas of Menashe hills and the Upper Galilee. The 55 animals involved were: - fauna: 31 foxes and 2 jackals; domestic carnivores: 12 dogs and 1 cat; farm animals: 5 cattle, 2 donkeys, 1 horse and 1 camel. Nearly 128,000 dogs were vaccinated in 1995, of which 5 to 10% were spayed/castrated. This is estimated to be 60 to 7 0 % of the owned dog population. Approximately 47,000 farm animals were also vaccinated.

Bovine spongiform encephalopathy Bovine spongiform encephalopathy (BSE) has never been recorded in Israel. The import of meat-meal and bone-meal of bovine/ovine origin into Israel for use in feed for food-producing animals has been banned by the VSAH since July 1990. "Specific bovine offal" (SBO: brain, spinal cord, tonsils, thymus, spleen and intestinal tract) are allowed to be imported only if they were derived from animals which had never received any feed concentrates containing ingredients of ruminant origin, excluding milk products. To safeguard the implementation of the said requirement, import permits are granted only from countries which have officially prohibited the feeding of bovines with such ingredients. Since 1991, all bovine brains, presented to the department of pathology in the KVI following any central nervous system or neuromotor clinical signs, are histologically examined for BSE changes. A total of 520 brains of bovines, older than 2 years, have been examined since 1991, as follows: Histopathological examination of cattle brains at Kimron Veterinary Institute, Beit-Dagan 1991 1992 1993 1994 1995 99 48 72 134 167 All were found to be free of BSE changes. The total number of bovines in Israel is 355,000, including 257,000 of the Israeli Holstein breed of which 115,000 are lactating cows in production, scattered in 1,650 dairy farms. The VSAH have taken the following measures to prevent the introduction of BSE into Israel since the initial notification about its appearance in the United Kingdom (UK) was received: December 1987: note in the Monthly Veterinary Bulletin, distributed to all State veterinarians, largeanimals practitioners and cattle breeders associations, summarizing the short communication of Wells et al. published in the Veterinary Record on 31 October 1987: "A novel progressive spongiform encephalopathy in cattle". May 1988: request to import live cattle for breeding from the UK refused "until more information is available on BSE". No such permits have been issued throughout the following years. December 1988: prohibition of import from the UK of animal meal of ruminant origin. March 1989: lecture by Dr R. Bradley (Central Veterinary Laboratory, Weybridge. UK) on BSE with slides and video to the State veterinarians and personnel of KVI at the VSAH Headquarters in BeitDagan. April 1989: Dr Bradley's paper included in the VSAH epidemiological quarterly (January-March 1989) and distributed to wide circle of professionals. April-May 1989: BSE video of the British Veterinary Services shown to all large-animal practitioners in regional meetings throughout the country. August 1989: pet food from the UK required to be accompanied by official certification confirming that the products do not contain SBOs or any material derived from animals which may be infected with BSE or other scrapie-like agents and that the exporting plant is under direct and official control of the State Veterinary Services. March 1990: animal meals for the feeding of farm animals allowed only from countries free of BSE, from approved plants under direct inspection of State Veterinary Services, and if accompanied by veterinary certificates indicating that no animal waste from other countries are included. -148- Julv 1990: total ban on import of meat meals of mammalian origin for the feeding of food animals (including poultry) from all countries. The Israeli policy regarding BSE was presented by the Delegate of Israel to the OIE in a meeting on BSE at the OIE Headquarters in Paris, 23 July 1990. September 1990: presentation and discussion on BSE during the annual Veterinary Symposium in Rehovot, with participation of many practitioners and laboratory workers. October 1990: reply from the Israeli Embassy in Brussels to the European Commission (DG VI) clarifying the Israeli requirements for the import of animal-related products from the European Community. The said requirements had been referred to in a previous letter from the Community to the Israeli ambassador as "impeding the free movement of goods between Israel and the European Community". Requirements were maintained unchanged. December 1990: import from the UK and Ireland of SBOs is prohibited. February 1991: import of SBOs from all other countries restricted to those derived from animals officially certified as never having received any feeds/concentrates containing ingredients of animal origin (excluding milk products). April 1992: BSE declared a notifiable disease; veterinary practitioners and the industry are briefed and requested to notify every suspected case to VSAH. October 1992: participation and training of a pathologist from the KVI in the Spongiform Encephalopathy Workshop III at the Central Veterinary Laboratory, Weybridge, UK. June 1994: letter sent to the Chief Veterinary Officers of all countries which are on the list of beef exporters to Israel, inquiring about the legal status in the respective countries regarding feeding of ruminant protein (excluding milk powder) to ruminants. January 1995: bovine meat import conditions were updated as follows and distributed to all exporting countries: 'A country in which BSE has been diagnosed shall be deleted from the list of countries approved for the export of meat/offals to Israel unless it has been proved that the following conditions have been conformed to: a. The disease has been declared compulsorily notifiable. b. An effective surveillance system, at least equal to the directions of the OIE in this matter, has been established. c. An effective tagging system which enables the tracing of cattle to the farms of origin has been established. Animals originating from farms on which BSE has been diagnosed shall be excluded from export to Israel. The importation of SBOs shall be forbidden from any country which has not prohibited the feeding of mammalian proteins to ruminants (excluding milk products). The importation of meat from countries in which BSE has been confirmed shall be permitted on condition that nervous and lymphatic tissues which have been exposed during the cutting process were removed from the carcass.' Special veterinary conditions are required from countries with high BSE incidence, including compulsory deboning and age restrictions for slaughtered animals. April 1995: implementation of the aforementioned veterinary import conditions. May 1995: the Israeli policy regarding BSE presented during the 63rd General Session of the OIE. December 1987 - May 1996: more than 300 items on BSE published in the Monthly Veterinary Bulletins, distributed to all State veterinarians, large-animal practitioners and cattle breeders associations. -149- Mav 1996: the Israeli VSAH import policy in relation to BSE hazards is under process of réévaluation in light of the information on suspected possible BSE/Creutzfeldt-Jakob disease connection and the desire to maintain Israel's freedom from BSE. Diseases of sheep and goats 3. Caprine and ovine brucellosis (excluding B. ovis) Following the termination of pilot programmes for the control of Brucella melitensis, restricted to the four districts most seriously affected, a country-wide control programme was launched in April 1995. In 1995, a total of 4,738 flocks were examined, including 151,409 sheep and goats, of which 147,291 were examined by means of the CF test in the National Brucellosis Laboratory in KVI, 2,883 by ELISA field testing kits and 1,235 by intradermal allergic tests. The total number of positive animals was 4,785, namely 3.16% of all animals examined. A total of 231 of the flocks (4.8%), including 11,484 animals, were found positive at a rate higher than 10%, and were thus slaughtered in their entirety. An infection rate of less than 10% was found in 675 flocks (14.2%), which were thus liable to the "test and slaughter" policy. The total number of animals slaughtered during 1995 reached 12,851, with compensation of approximately 7.4 million ILS (approximately 2.4 million USD) being paid. Of the surveyed flocks, 3,832 (81%) were found negative. The Brucellosis-Free Dairy Flocks Scheme, a voluntary scheme for dairy-sheep and dairy-goat breeding flocks, has been continued, adding 21 new flocks. At the end of 1995, the club included 112 flocks with 25,000 sheep and goats. In these flocks periodic testing is carried out. Vaccination of ewe-lambs and young female goats up to 7 months old was increased and, in 1995, included 82,587 animals, compared to 65,130 in 1994 and 53,589 in 1993. The vaccinations are liable to payment by the flock owners, a fact which might be an obstacle to obtaining a higher vaccination coverage. The Brucellosis Control Programme steering committee is headed by the Veterinary Field Services and includes representatives of various units of the VSAH, the State Budget Department, the Ministry of Health, the directorship of the Ministry of Agriculture and the Sheep Breeders Association. In 1995, 246 Malta fever cases in humans were officially reported in Israel by the public health authorities, compared to 226 during 1994 and 338 during 1993. Though a significant reduction was observed in several districts, there was a rise in the districts of Beer Sheva and Jerusalem. Most cases in Jerusalem occurred in its eastern part, resulting from the consumption of contaminated dairy products. A public education programme has been prepared and is to be carried out by the Ministry of Health, in collaboration with the VSAH. 4. Scrapie Following the stamping out of the first scrapie flock in Israel in October 1993, no further cases were observed during 1994 and 1995. It is hoped that with the destruction of the said flock, in which 4 sheep of the Chios breed and crosses were found affected, Israel may have regained its freedom from scrapie. During 1994 and 1995, 102 ovine brains of adult animals with CNS or neuromotor clinical signs were histologically examined in the KVI, all with negative results regarding scrapie. m . OTHER DISEASES Salmonella enteritidis infection The reduction in the occurrence of Salmonella enteritidis infections in poultry, observed during 1994, was continued throughout 1995 with a consequent significant reduction in the number of stamped-out poultry flocks, from 24 (including 204,675 birds and more than 1.72 million hatching eggs) in 1993, to 9 flocks (85,438 birds and 132,090 hatching eggs) in 1994 and 1 flock, including 15,274 birds, in 1995. -150- Compensation paid in 1995 amounted to 105,000 USD compared to 330,000 USD in 1994 and 1.3 million USD in 1993. This was partly due to the improvement of sanitary conditions in poultry farms associated with the successful introduction of the inactivated S. enteritidis vaccine, combined with the live attenuated S. typhimuhum vaccine in parent-stock breeding flocks. In addition, the VSAH was able to reduce the severity of the measures applied for the control of S. enteritidis in poultry farms thanks to the enforcement of new State regulations regarding the handling of table eggs, their collection, transportation, marking, packing, chilling and marketing.

Ces mesures n'étaient en vigueur que dans la province de Casería. Cette Décision communautaire a été approuvée au niveau national par l'ordonnance du 14 septembre 1995. 2. Maladie vésiculeuse du porc Au cours de 1995, un total de 18 foyers a été enregistré dans des élevages de porcins, dans des abattoirs (publics et privés), et dans des porcheries de déchargement commercial. Dans deux cas, la maladie a été détectée suite à des contrôles effectués dans le cadre du plan d'éradication. La Décision de la Commission européenne du 13 septembre 1994 a été approuvée au niveau national par l'ordonnance du 2 décembre 1994 qui a lancé le programme d'éradication et de surveillance de la maladie vésiculeuse dans les élevages porcins sur l'ensemble du territoire national. Au cours de la première année de la mise en œuvre de ce plan (1995), les élevages de porcins reproducteurs ont fait l'objet de contrôles. 3. Péripneumonie contagieuse bovine En vertu de l'ordonnance du 3 février 1993, la mise en œuvre par les régions et les provinces autonomes de Trento et Bolzano à la fois du plan de sérosurveillance dans les élevages de bovins et de bufflesses, et du plan d'inspection sanitaire dans les abattoirs publics et privés sur le territoire national vis-à-vis de la maladie, est devenue obligatoire. Le monitorage de l'introduction d'animaux en provenance des pays tiers et de l'Union européenne s'est poursuivi. -152- Entre janvier et décembre 1995, 450 000 prélèvements au total ont été soumis à des épreuves sérologiques. Compte tenu de la situation satisfaisante de l'Italie vis-à-vis de cette maladie, le pays peut être considéré indemne de péripneumonie contagieuse bovine conformément au Code zoosanitaire international de l'OIE. L'Italie a en outre demandé à la Commission européenne d'abroger la Décision 91/56/CEE du 21 janvier 1991, prévoyant des mesures de protection en matière de péripneumonie contagieuse bovine sur son territoire. 4. Peste porcine africaine Tout comme au cours des années passées, la diffusion de la maladie s'est limitée à la zone d'enzootie de la province de Nuoro (Sardaigne). Les mesures envisagées par le plan d'éradication ont été poursuivies en 1995, conformément à la réglementation régionale adoptée en 1993 et aux Décisions de la Commission européenne 90/217/CEE et 94/881/CE. Les dispositions de la Décision 95/108/CE modifiant la Décision de la Commission du 30 juillet 1992 (92/451/CEE) prévoyant des mesures de protection contre la peste porcine africaine en Sardaigne ont été approuvées au niveau national par l'arrêté du 4 juillet 1995. Un Comité national de coordination et de surveillance a été mis sur pied par le ministère de la santé aux termes de l'article 7 de l'arrêté mentionné ci-dessus. 5. Peste porcine classique A la différence de l'année passée, pendant laquelle les foyers n'avaient été observés qu'en Sardaigne, des cas d'infection se sont déclarés également dans certaines régions qui pendant longtemps avaient été indemnes : province de Bolzano (porcins), de Piacenza (sangliers d'élevage) et de Prato (porcins). De l'enquête épidémiologique menée par les Unités Sanitaires Locales (USL), il ressort que ces animaux avaient été nourris avec des déchets de cuisine non traités. Lors de la saison de la chasse 1995/1996, des contrôles pour la peste porcine classique ont été effectués chez les sangliers abattus par les chasseurs dans les zones où les foyers sus-mentionnés se sont produits. Cette enquête a été menée également en Sardaigne. Le plan de sérosurveillance visait à apprécier la présence et la diffusion du virus de la peste porcine classique dans les élevages de reproduction, surtout pour les souches virales à faible virulence, aussi bien que pour le contrôle des anticorps de cette maladie chez les porcins à l'engrais. 6. Maladie de Newcastle Le premier foyer, coïncidant avec un seul cas clinique, a été détecté chez un pigeon sauvage trouvé mourant sur les rives d'un fleuve et amené dans un laboratoire pour essayer de le soigner. Le deuxième foyer a été détecté dans une exploitation avicole avec un total de 200 animaux, parmi lesquels des poulets et des pintades ; tous ont été abattus. L'origine de la maladie est à ce jour inconnue, même si l'on a constaté que dans cette exploitation il y a souvent des mouettes, des tourterelles et des pigeons sauvages qui auraient pu être à l'origine de l'infection. Il convient de préciser que la baisse du nombre de cas de maladie en 1995 n'est pas due à de nouvelles dispositions ou à des plans de lutte spécifiques mais plutôt, du point de vue épidémiologique, à l'évolution naturelle que cette maladie a suivie en Italie. -153- II. MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Fièvre charbonneuse Seuls 2 cas de fièvre charbonneuse ont été enregistrés en 1995 sur l'ensemble du territoire national. En plus des mesures de police vétérinaire adoptées pour les foyers, la prophylaxie de la fièvre charbonneuse envisage le recours à la vaccination préventive chez les espèces sensibles (bovins, ovins, caprins et équidés) dans les zones à haut risque en raison de la présence de "champs maudits", les régions concernées devant préalablement solliciter l'autorisation du ministère de la santé. 2. Rage Depuis le mois de juin 1994, aucun cas de rage sylvatique n'a été signalé dans la province de Bolzano. Les autorités sanitaires de la région Frioul-Vénétie Julienne et de la province autonome de Bolzano, afin d'empêcher l'apparition et la propagation de la maladie ont mis en place des mesures de prophylaxie qui prévoient, dans les zones les plus touchées, des plans de vaccination antirabique des renards par voie orale avec le vaccin SAD B 19 importé d'Allemagne. Les campagnes de vaccination ont été effectuées au printemps. La Slovénie, qui confine avec l'Italie, a mis en place un plan d'éradication de la rage approuvé et financé par l'Union européenne. Comme les années précédentes, le ministère de la santé a promulgué une ordonnance rendant obligatoire la vaccination antirabique des chiens et autres animaux domestiques dans les zones infectées de rage vulpine. Le monitorage de la rage sur le reste du territoire national s'est poursuivi par l'analyse sérologique de nombreux prélèvements provenant d'animaux domestiques et sauvages effectuée par les instituts zooprophylactiques compétents pour chaque zone, avec des résultats satisfaisants. -154- J O R D A N INTRODUCTION Although there was no change in the Enzootic Disease List of 1995 compared to the previous years and despite the intensification of disease control measures, a slight increase in disease challenge was noted. The poor pasture in the southern and western parts of the country, which triggered a vast animal movement towards the north-east, where pastures are richer, could have caused the slight increase in the disease challenge, bearing in mind that the north-east part of Jordan is in the neighbourhood of three countries and that animal movements across the borders are not uncommon. In 1995, the private veterinary sector demonstrated more involvement in activities with large animals, sheep and goats i.e vaccinations, treatments, diagnosis and clinical work. In previous years, such responsibilities were in the hands of governmental veterinarians. Due to the geographical location, we assume that the major disease problems we are facing in Jordan also exist in other Middle East countries. Without a regional concept, control of these diseases will continue to be a remote target. This was the case in 1994 and 1995 and will be in the future until the Middle East region countries find their way to cooperation and a collective approach of problems. I.

More animals were vaccinated in 1995, and it was the first year in which large-scale vaccination of sheep was carried out. Sero-surveillance and virus identification was continued. Results showed a high prevalence of the disease. 03-94 12-94 -155 - 2. Rinderpest Around 15.4% of the cattle population was vaccinated in 1995, due to the geographical location of the country, the absence of regional cooperation and the lack of advanced diagnostic facilities locally. Together, these factors restrict the ability of the Jordanian Veterinary Authorities to declare freedom from the disease as per international regulations. It is hoped that with the help of the IAEA the situation will be ameliorated. In 1996, the IAEA is going to provide Jordan with the equipment and the acumen to achieve instrumental monitoring of the disease. In view of the volume and quality of the disease monitoring carried out until now, a provincial declaration of freedom from rinderpest is imminent (1996). 3. Peste des petits ruminants Peste des petits ruminants (PPR) is a major disease problem first identified serologically in 1992. The clinical form of the disease was minor at that time; losses among the flocks sampled and tested were insignificant whereas about 2 3 % of samples were serologically positive. From 1992 until now the disease has become more complicated: factors playing a significant role include animal movements across the borders (north-eastern part) and the concurrent presence of bluetongue and foot and mouth disease. Routine vaccination has been carried out by the veterinary field staff on an ongoing basis. Some 16% of the sheep and goat population were vaccinated in 1995 using locally produced or imported rinderpest vaccines. Monitoring of vaccinated flocks has shown that, in general, seroconversion is either absent or delayed. For better protection of sheep and goats against PPR the Veterinary Department is planning to use the PPR vaccine exclusively as soon as it is available. 4. Bluetongue Although serological evidence ( 3 3 % of animals seropositive) of the presence of the disease has existed since the early 1980s, very few clinical cases especially in exotic sheep breeds or local breeds from the south-eastern part of the country have been reported. No vaccination has been carried out. It is believed that the sheep / goat population in the south-eastern part of the country is free from any form of the disease, due to the absence of the vector. The serotypes which have been so far identified in Jordan are 2. 4, 6, 10. 5. Sheep pox and goat pox A disease problem which is to a considerable extent under control. No outbreaks occurred in 1995 and the disease incidence in 1994 was the lowest since 1982. However, there was no major difference between 1994 and 1995. Vaccination campaigns continue annually (in 1995 around 3 5 % of the sheep and goat population was vaccinated). The vaccine used is produced locally. 6. African horse sickness Vaccination against African horse sickness is prohibited and the analysis of serum samples in reference laboratories has always given negative results. 7. Newcastle disease Newcastle disease is a problem facing poultry farmers, especially in multi-age broiler farms. Disease monitoring is inadequate due to the lack of diagnostic facilities and specialization. The private veterinary sector is the main body supervising the poultry industry in Jordan. n. LIST B DISEASES Diseases of multiple 1. species Rabies A number of confirmed cases were reported among animal species in 1995. Many cases of human bitten by dogs were reported. Fortunately, there were no human fatalities due to the disease. -156- Diseases of sheep and goats 2. Caprine and ovine brucellosis (excluding B. ovis) Brucella melitensis is so far the causative microorganism which has been isolated. The impact of the disease on livestock productivity has been tremendously minimized in the last three years compared to 1988-1989. Vaccination is carried out on an ongoing basis using a locally produced Rev-1 vaccine in sheep and goats. Jordan is awaiting the implementation of the 1993 Amman Brucellosis Meeting recommendations in addition to the Brucellosis Control Programme proposed by the FAO and the regional programme (Jordan, Syria, Iraq and Lebanon) proposed by the Arab Organization for Agricultural Development (AOAD). Diseases of horses In general, major equine diseases have never been reported in Jordan. Serum analyses for either export or monitoring purposes are always negative. In Jordan equines are only vaccinated against tetanus, anthrax and influenza.

Comprehensive poultry disease monitoring in Jordan is still unestablished. III. OTHER DISEASES Although many diseases included in FAO List C are notifiable in Jordan, the existing ones have no significant impact on the animal wealth. The majority of these diseases have never been reported clinically or by laboratory means. -157- KOREA (Republic of) INTRODUCTION The Veterinary Services of the Ministry of Agriculture, Forestry and Fisheries are undertaking an active animal health surveillance and monitoring programme for notifiable diseases in accordance with the Livestock Epidemics Prevention and Control Act, which was promulgated on 30 December 1961 and amended in part on 5 January 1995. According to the reorganisation of the Government Ministries in December 1994, the Veterinary Services have been slightly strengthened by an increase in the number of animal quarantine officials in the National Animal Quarantine Services and the establishment of the Foreign Animal Disease Research Centre in the National Veterinary Research Institute. A Maximum Containment Research Laboratory in the Foreign Animal Disease Research Centre has become operational and should lead to a better understanding of exotic diseases and the implementation of the task force scheme for the control of exotic animal diseases. In February 1995, a Korean edition of the OIE International Animal Health Code and Manual of Standards for Diagnostic Tests and Vaccines was published and distributed to the veterinary officials for training and educational purposes. The Korean edition was published with the permission of the OIE. In 1995, there were no significant changes in animal health status compared to 1994. I.

Feb 1 11 Bluetongue Sheep pox and goat pox African horse sickness African swine fever Highly pathogenic avian influenza (fowl plague) date of last outbreak) Rinderpest (1931) diseases Classical swine fever (hog cholera) Classical swine fever is still one of the most important diseases of swine in Korea, thus a nation-wide control scheme is in force, including voluntary vaccination and a slaughter policy for infected herds, and has been effective in controlling the disease. 2. Newcastle disease In 1995, there was an increased number of outbreaks (73) and chickens diagnosed with Newcastle disease (a total of 510,193 chickens) compared with 10 outbreaks (involving 41,920 chickens) in 1994. Newcastle 12-94 12-94 -158- disease is still regarded as one of the causes of damage to the poultry industry in the Republic. To control the disease, a mass vaccination programme has been adopted and is implemented each year. Strict quarantine measures were applied to prevent the introduction of other List A diseases in the Republic. II. LIST B DISEASES 1. Aujeszkv's disease In 1995, a total of 52 outbreaks were diagnosed as positive reactors in Aujeszky's disease tests, compared to 14 outbreaks in 1994. The test and slaughter scheme with compensation is the current strategy in controlling the disease. Although vaccination against Aujeszky's disease is prohibited, killed vaccines (gl-deleted vaccine only for the purpose of differential diagnosis of field infection and vaccination) have been permitted on restricted farms, since 1995, only under the serological monitoring system. 2. Rabies In 1995, there was a slight decrease in the number of outbreaks. The source of infection was identified as wild raccoon. The outbreaks of rabies are restricted to certain regions, such as the northern parts of Kyunggi and Kangwon provinces. Diseases of cattle 3. Bovine brucellosis There was a total of 135 outbreaks with 322 cases of sero-positive reactors in 1995, representing a considerable decrease compared to the 225 outbreaks in 1994. The test methods currently employed include the milk ring test, rose bengal plate test and complement fixation test. Since the introduction in the early 1950s of the national test and slaughter programme with compensation, herd infection rates have been dramatically reduced, from 2 0 % in the 1950s to around 0 . 1 % in the 1990s. Cheju island showed a particularly high incidence of this disease (61 outbreaks involving 118 cattle in 1995). 4. Bovine tuberculosis In 1995, there was a total of 164 outbreaks of bovine tuberculosis, representing a slight increase compared to 1994 (112 outbreaks). The test and slaughter scheme with compensation, including restrictions on cattle movements from farms with positive reactors, was maintained. Diseases of pigs 5. Transmissible gastroenteritis There was a total of 38 outbreaks of transmissible gastroenteritis in 1995, representing a very slight increase compared to 12 outbreaks in 1994. Transmissible gastroenteritis shows mixed infection with porcine epidemic diarrhoea. Both infections occur during winter. Porcine epidemic diarrhoea, a rather new disease with clinical signs in piglets quite similar to those of transmissible gastroenteritis, has been recognised as one of the most devastating diseases in the pig industry of the Republic of Korea. 6. Porcine reproductive and respiratory syndrome Since the first isolation of the porcine reproductive and respiratory syndrome (PRRS) virus and the reported serological incidence of 6.3% in pigs in 1993, there has been a slight increase in the number of positive reactors; however, most of the cases were regarded as a mild form with rare clinical signs. An imported vaccine is currently under experimentation by field trials, and the autogenic vaccine using the Korean isolates from the mild form PRRS is under development in order to eliminate naturally infected pigs. -159 - KUWAIT INTRODUCTION Upgrading livestock resources The Public Authority for Agriculture Affairs and Fish Resources completed the preparation of a nationwide Livestock Improvement Project entitled Upgrading and Development of Animal Wealth of the State of Kuwait, of which Animal Health is a component. Privatisation of curative animal care delivery The policy to privatise the curative animal health delivery system was translated into practice with the handing over of three out of the six government veterinary clinics to the private sector and the complete withdrawal the public sector from areas where the private sector are operating. Private practices provide curative health care to all domestic species, and preventive measures except to non-ruminant livestock and intensive poultry. Curative animal health care delivery by the public sector services are restricted to Sulaibiya and Wafra areas. Prophylaxis against major animal diseases Prevention of the major diseases of ruminant livestock was undertaken through a joint effort of a contracted International Private Company and the Preventive section of the Animal Health Department. As well as technical backstopping to private veterinarians working in the poultry industry, compulsory immunisations of companion animals was provided by the Animal Health Department. Establishment of a Regional Animal Disease Control Centre A disease control centre was set up at Kebd and became operational towards the last quarter of the year. The centre, which is located where an estimated 6 5 % of the national small ruminant population are kept, also serves as a focus for animal disease surveillance. Disease sun>eillance Routine animal disease reporting system and surveillance are being strengthened. A system for routine reporting of the occurrence of notifiable diseases and monthly work progress by the private veterinary practices was put in place. Seminars were held for veterinarians and veterinary assistants on routine animal disease reporting. Disease surveillance was also undertaken by the Quarantine, Preventive and contracted private consultancy firm involved in ruminant livestock immunisation project. Manpower development Twenty-nine individuals completed training as veterinary assistants and got deployed to work in the various sections of the Animal Health Department. Capability Building Tissue culturing and ELISA technique were put in place in the Virology laboratory, while ELISA was introduced in Serology and Bacteriology Laboratory of Animal Health Department, towards the later part of the year. -160 - I.

Contagious bovine pleuropneumonia The above disease remained undetected since the Iraqi invasion that decimated the dairy industry and large populations of small ruminants. Bacteriological, serological and pathological examinations of suspected clinical cases could not confirm its presence. 08-94 1994 12-94 - 161 - 3. Sheep pox and goat pox About 1,279 animals, mostly sheep, were affected. 4. Newcastle disease Incidence has declined through routine vaccination of poultry in intensive units. However, the immunosuppressive effects of infectious bursal disease seems to retard progress in the effective control of this disease. II. LIST B DISEASES 1. Brucellosis Brucellosis is also an endemic zoonosis in the State of Kuwait, whose incidence has declined with intensive vaccination campaign underway for many years now. However, still cases of abortion and retained placenta are encountered from which, in dairy cattle, Brucella abortus are isolated by the Bacteriology Laboratory. Furthermore, 224 cases of Brucella infections in ruminant livestock from local sources and 287 small ruminants imported from various countries were confirmed by serodiagnoses. 2. Bovine tuberculosis The above disease remained undetected since the Iraqi invasion that decimated the dairy industry and large populations of small ruminants. Bacteriological, serological and pathological examinations of suspected clinical cases could not confirm their presence. 3. Infectious bursal disease (Gumboro disease") Infectious bursal disease (Gumboro disease) is endemic but through regular vaccination programme the magnitude of this disease has been reduced. -162- L A T V I A INTRODUCTION As wild animals are serious potential reservoir of diseases, wild boar sera investigations were started in 1995 and will be continued. Out of 71 samples tested: - 15 were positive for classical swine fever 3 9 were positive for parvovirus infection 5 were positive for leptospirosis 2 were positive for brucellosis all were negative for chlamydiosis.

LIST B DISEASES 1. Rabies Rabies was confirmed by laboratory examination in 224 animals, representing 38.4% of all suspected cases. Of the confirmed cases, 168 (75%) were in wild animals (mainly foxes and raccoon dogs) and the remainder were in livestock. An oral vaccination programme for wild animals was resumed in the seven most endangered administrative districts. Diseases of cattle 2. Enzootic bovine leukosis In 1995, under a routine test programme, all cows and heifers from the age of 6 months were tested with IDR and positive results were found in 3.2% of the total (15,941 cases). Since 1991, as a result of disease control measures, the number of infected animals has been reduced twelve-fold. Diseases of pigs 3. Porcine enterovirus encephalomyelitis The disease was registered in 17 farms in 12 administrative districts. The prevalence of the disease was 2.1 times higher and the number of cases 24.3 higher than in the previous year. - 163- L E S O T H O INTRODUCTION The Veterinary Services Division is one of the three divisions of the Department of Livestock Services of the Ministry of Agriculture, Cooperatives Marketing and Youth Affairs. The other two divisions are Animal Production and Range Management. The objective of the Veterinary Services Division is to increase livestock productivity by control of animal diseases of economic as well as those of public health importance. The operations of the Veterinary Services are therefore divided into three areas: - Veterinary Field Services Meat Hygiene Animal Disease Investigations Veterinary Field Services In each of the 10 districts there is a veterinary clinic headed by a veterinary officer. In each district, there are 4 to 6 Livestock Improvement Centres (LICs) manned by Livestock Assistants. There are a total of 48 LICs in the country. During 1995, a total of 23 Livestock Assistants completed their training and alleviated the understaffed LIC situations. The LICs are the extension centres at the grass roots level from where veterinary services, sale of drugs and breeding stock are offered to farmers. The veterinary clinics oversee the veterinary activities in a district. Meat Hygiene Meat inspection and hygiene at the national abattoir and municipal abattoir in Maseru are the responsibility of the Veterinary Division. Due to shortage of staff, the meat inspection service in the other nine districts is the responsibility of the Ministry of Health through health inspectors. Animal Disease Investigations The Central Veterinary Laboratory in Maseru coordinates all disease diagnostic services. I.

Vaccination of 645 cattle and 23 equids was conducted. 2. Bluetongue The disease was seen throughout the country, especially towards the end of 1995. Voluntary vaccination at the farmers' request was the method of approach. 3. African horse sickness African horse sickness is enzootic in the country. Vaccination of equids was done at the farmer's request. A total of 682 horses were vaccinated. 4. Newcastle disease After the high mortality due to Newcastle disease observed throughout the country in 1994, fewer outbreaks were recorded in 1995. A total of 500,000 vaccinal doses were administered. n. LIST B DISEASES Diseases of multiple 1. species Anthrax A new outbreak of anthrax occurred in Mafeteng district in February 1995. The last previous outbreak was in Maseru district in 1971. High mortality was experienced in cattle and few horses. Of the 154 human cases, 10 died of the disease. The humans had eaten dried meat from carcases of animals which died of anthrax. In May 1995, the FAO provided emergency assistance during the outbreak. The resources were made available to enlist the services of a consultant, who laid down guidelines for anthrax surveillance and control. Surveillance of anthrax included reporting by the public of all animal deaths to the veterinary authorities and collection of samples including bones for culture and isolation of the bacilli. A laboratory technologist and a veterinary officer were trained in the diagnosis of the disease in the Republic of South Africa under the provision of FAO assistance. Control measures put in place were quarantine of the outbreak area until six weeks after the last reported outbreak as well as annual vaccination of cattle in low lying areas with a potential for accumulation of the anthrax spores. The present legislation provides for movement restrictions to be put in place in case of an outbreak of anthrax. 2. Echinococcosis-hydatidosis The hydatid cysts recorded were seen during meat inspection at the national abattoir in Maseru only, since meat inspection at other district slaughter slabs was conducted under the Ministry of Health. A closer collaboration in meat inspection was agree upon between the two ministries. 3. Rabies Only one case of rabies was suspected. This was in Quthing district, where a dog which showed strange behaviour was killed by villagers. No confirmation was carried out. Fluorescent antibody technique is usually used as a confirmatory test. Annual vaccination of dogs and cats was conducted throughout the country free of charge. A total of 26,212 dogs and cats were vaccinated. This figure was lower than that of 60,885 covered in 1994. Legislation provides for compulsory vaccination of dogs in the event of an outbreak. -165- Diseases of cattle 4. Bovine anaplasmosis and babesiosis These diseases were reported throughout the country. in time. Tick control was encouraged and done at the spraying of cattle. The dry summer, and very cold survival or building of high tick populations. Hence priority. 5. Mortality was low among cases reported and treated farmer's request. There was no organised dipping or winter in the highlands of Lesotho do not favour an organised programme for tick control is never a Bovine brucellosis Bovine brucellosis was not a problem. Regular testing of dairy herds was conducted using the milk ring test. Suspected reactors were followed up by the rose Bengal test. Only 2 of the 1,781 cattle were positive and were destroyed. No vaccination of cattle against brucellosis was practised. III. OTHER DISEASES Multiple species 1. diseases Blackquarter (blackleg) Two outbreaks of the disease were recorded, one each in Mokhotlong and Maseru districts. A total of 79,750 cattle were vaccinated against blackquarter throughout the country in 1995. Sheep and goat 2. diseases Sheep scab Since Lesotho is wool producing country, sheep scab is a disease of great economic importance, adversely affecting wool production and thus export earnings for the country. The disease was reported throughout the country, involving a total of 12,581 sheep. An annual double dipping of all sheep and goats was conducted throughout the country during the months from January to March. The prevailing drought made dipping very difficult due to scarcity of water. Some animals were not dipped at all while others were dipped once. Existing legislation makes it compulsory for farmers to dip their sheep and goats during an outbreak. A total of 1,966,134 sheep and goats were dipped. -166 - L I B A N INTRODUCTION La situation épizootiologique au Liban s'est bien améliorée en 1995, à la suite de la réorganisation des Services vétérinaires au ministère de l'agriculture et des campagnes de prophylaxie et de prévention qui ont été entreprises contre la majorité des maladies contagieuses. Les contrôles à la frontière sont beaucoup plus stricts et l'application des mesures internationales est en règle. Il est prévu de construire six clos de quarantaine au cours de 1996. Le programme de lutte contre la brucellose a donné de bons résultats, vu la stagnation de la maladie dans les zones infectées préalablement. Le dépistage des maladies équines majeures (peste équine, anémie infectieuse, dourine, morve) par des prélèvements de sang envoyés aux laboratoires de Pirbright et de New Haw a montré l'absence de ces maladies dans le cheptel équin.

To meet the needs of the Veterinary Services in the different parts of the country and provide specialist and veterinary assistance to raise the standard of veterinary service. To interview and evaluate expatriate veterinarians applying for service in the country. In consultation with the authorities concerned, to study the needs of the country for drugs, vaccines and equipment. To issue permits for qualified individuals to deal in and sell veterinary products, and to lay down the necessary regulations for such licences. To control fully all animal quarantine and supervise all imports and exports of animals and animal products. To organise animal quarantine and animal movements, and to propose laws to be enacted for this purpose. To lay down animal health regulations and specifications for the import and export of animals, meat and other animal products. To develop and promote laboratory services for diagnostic and production purposes. To develop drug preparation locally. To participate and contribute in conferences, meetings and study workshops in the field of animal health. To participate in the programmes of animal health education extension services. Import and export policies for animals and animal products Since Jamahirya is mainly an importing country, the aim is directed towards a higher level of veterinary surveillance, supervision and endorsement of health certificates on the part of the exporting countries to safeguard against the introduction of new diseases into the country. There are quarantine stations in all sea and land ports of entry to Jamahirya, which are 17 in number. The main legislative measures applicable to imports of live animals are the following: 1. 2. 3. The animals must originate from a disease-free zone or area in the country of origin, with respect to OIE Lists A and B diseases of these animals. The animals must be accompanied by a valid health certificate issued by an authorised veterinarian in the exporting country and attested by the official veterinary service. The certificate shall conform to the international sanitary code and regulations. The same applies to semen and animal products and raw materials of animal origin. Exports of animals are very limited and consist only of pet animals. The certificates are authorised only by Government employed veterinarians, attested and stamped by the chief of the Veterinary Service. -168- Veterinary legislation and laws on quarantine in Jamahirya 1. 2. 3. 4. 5. 6. 7.

The outbreak was in the eastern part of Libya, in the Ejdabia area about 90 km west of Benghazi municipality and was quickly controlled by restrictions on animal movements to and from the affected areas. Vaccination was applied using a type O vaccine and all other necessary sanitary measures were introduced. The policy of the country towards FMD is to vaccinate bovine herds twice a year. 2. Sheep pox and goat pox Sporadic cases of sheep pox have been reported annually from different areas. A programme of annual vaccination using imported vaccine is applied and involves more than 7 0 % of the national flock. 3. Newcastle disease A regular vaccination programme is applied using imported vaccine (Hitchner B1 and La Sota) and there are routine immunological studies on the immunity level of different kinds of poultry chicks, especially parent flocks and day-old chicks, to determine maternal immunity and provide advice on the timing of vaccination and revaccination where necessary. II. LIST B DISEASES Diseases of multiple 1. species Anthrax No cases of anthrax were reported in 1995. Reasonable measures including emergency and routine vaccination are practised using imported vaccines. 2. Echinococcosis-hydatidosis Some cases are still recorded each year. The Veterinary Service has used reasonable control measures to protect the human population against hydatidosis. The measures consist of condemning affected parts of organs in the slaughterhouse, control and destruction of stray dogs and periodic preventive treatment of domestic dogs. 3. Rabies Libya is still free of rabies. 4. Screwworm (Cochliomyia Screwworm (Cochliomia surveillance. 5. hominivorax) hominivorax) was eradicated in 1991 and this has been confirmed by intensive Mange Many cases of mange occurred in sheep and camels. The disease is mainly under control through the use of spraying or an injectable solution, for treatment of prophylaxis. Sheep are dipped annually during the shearing season (May to June) for prophylaxis and treatment. During the cold seasons, injectable medicines are chiefly used. -170- Diseases of cattle 6. Bovine brucellosis Three cases of abortion due to Brucella abortus were reported in public sector modern dairy complexes and in privately owned cows. Rigorous blood and milk testing and slaughter of positive reactors has been practised since 1981. The programme is still being continued. Diseases of sheep and goats I. Caprine and ovine brucellosis (excluding B. ovis) Brucellosis in sheep and goats due to Brucella melitensis biotypes 1 and 2 is enzootic among sheep and goat flocks mainly in the western mountainous area of the country and resulted in some human cases. Diseases of poultry 8. Avian infectious bronchitis Infectious bronchitis was not recorded in 1995. Routine immunological studies, using haemagglutination inhibition tests, are carried out to determine the post vaccination immunity level in different poultry flock units so as to select the best time for future vaccination. 9. Fowl typhoid (Salmonella sallinaruiri) Some cases are reported each year. Preventive measures include regular testing of blood, removal of all positive cases and hygiene-sanitary measures. 10. Infectious bursal disease (Gumboro disease") Gumboro disease (type 1) was confirmed in 1988 and the incidence of outbreaks increased from that time until March 1990, when it started to decline. In March 1991 the incidence started to increase again mainly due to a change in the kind of imported vaccine in use at that time. After a return to the previously used vaccine, the incidence declined rapidly and from that time the incidence of the disease has been very low. Control measures consist of a strong vaccination programme for parent flocks, controlling the parental antibodies in offspring, and recommending the most suitable time to vaccinate chicks using imported vaccine. II. Marek's disease A. few cases were reported in 1991-92 in the parent flock of a big poultry unit. All locally hatched chickens from this unit are vaccinated at one-day-old in hatcheries using cell-associated virus vaccine. Diseases of 12. lagomorphs Viral haemorrhagic disease of rabbits Since 1993, the disease has been kept under control by the application of a vaccination programme to all breeding stocks and a prohibition on imports from infected countries. III. OTHER DISEASES 1. Botulism 1 Sporadic cases were recorded in certain areas. A vaccination programme is applied in these areas using imported polyvalent vaccine. -171 - 2. Enterotoxaemia Many cases of enterotoxaemia were recorded, particularly in rich pasture areas and in nearby livestock rearing farms. Most cases were due to Clostridium perfringens types C and D. A vaccination programme had been applied throughout the country using imported polyvalent vaccine. 3. Ticks and tick borne diseases A few cases of tick infestation were recorded in illegally imported animals, especially in camel flocks in certain areas, and this is now under control. The following species of tick were identified in Libya: Hyalomma anatolicum excavatum, sanguineus, H. marginatum turanicum, R. turanicus, H. impeltatum, R. bursa. Rhipicephalus -172- L I T H U A N I A I.

Comments 1. on selected diseases Foot and mouth disease For surveillance purposes, blood from elk, deer and wild boar in the districts bordering with Poland and Belarus was tested for FMD antibodies . 2. Classical swine fever (hog cholera) After a 14-year interval, sporadic cases were registered in the south-eastern part of Lithuania in 1990. Stamping-out measures were taken and vaccination was started; however, attempts to completely eradicate the disease failed. Sporadic cases were registered in 1991, but there was no spread into the western region of the Republic. It should be noted that cases of the disease have also been observed in wild fauna (wild boar). Large farms conduct vaccination against the disease. Measures against the disease have been strengthened in all respects. A total of 28,900 pigs were vaccinated in 1995. In some districts, where classical swine fever had previously been recorded, blood from hunted wild boar was tested for antibodies. 3. Highly pathogenic avian influenza (fowl plague) and Newcastle disease On testing blood samples, moderate titres to Newcastle disease virus were occasionally found in all poultry farms; however, no clinical evidence (clinical signs, deaths, pathological anatomical changes) has been found. At present, all poultry are vaccinated against Newcastle disease. In 1995, some 2,137,800 birds were vaccinated. -173 - II. LIST B DISEASES Diseases of multiple 1. species Anthrax Outbreaks have been registered since 1920. During the last outbreak, in 1986, a total of 357 cases of the disease were registered. In the infected zones, animals are regularly vaccinated, starting in the third month of life, using a lyophilised vaccine obtained from capsules with avirulent spores of anthrax in a stabilised medium. All infected zones are passportized and isolated. Drainage and excavation of land is conducted in coordination with the Veterinary Service. Constant veterinary control is performed in respect of slaughter of animals, selection of offals and processing. 2. Aujeszky's disease Vaccination with inactivated vaccine is practised on three pig farms only. Previously, live vaccine was used. Regular control of the disease is performed. 3. Rabies In 1995, 147,000 vaccinations were performed. Rabies was registered in 23 districts of the country. Distribution of cases by species was as follows: 22 cattle, 15 dogs, 15 cats, 23 foxes, 6 raccoon dogs and 2 martens. Major foci of rabies were registered in Panevezys, Kelme, Joniskis, Plunge and Siauliai districts. These districts were subjected to extra vaccination of all animals. Reductions in the number of wild animals were achieved by shooting. 4. Salmonellosis The main causes for the occurrence of the disease are: neglect of hygiene and technological requirements in processing of carcases, violation of incubation regimes, and ungranulated combined fodders. Of 6,325 samples of pathological substances, 173 cases of Salmonella were isolated (S. enteritidis, S. typhimurium). On analysing 668 samples of fodder and additives in the National Veterinary Laboratory, 4 samples gave a positive result. On two farms swine salmonellosis was registered. A total of 670 pigs were lost as a result of the disease. In order to decrease the occurrence of salmonellosis, stricter measures for the control of production of combined fodders and the strict observance of instructions against the disease are planned. Cattle 5. diseases Bovine brucellosis In post-war years, bovine brucellosis was widespread in the Republic. Later, an isolation station was set up in Silute, where vaccination was applied. However, the disease lingered on, with one outbreak in 1971 and another in 1976. The disease ended with the destruction of all sick animals. To try to determine the aetiology, naturally infected zones were investigated. It was established that, in separate districts, 8 to 13% of hares were infected. During the eradication and control measures taken in 1978, animals in the last infected zone were slaughtered. A new outbreak in 1992 was due to the penetration of the disease from a neighbouring country. No more spots were registered. Cattle showing a positive reaction were slaughtered in meat processing plants. All related measures in the Republic have been strengthened: strict counting of abortions and stillbirths; laboratory testing of foetuses and blood. Planned investigations on the territory of former collective farms have been carried out every 45 days, in the district and neighbouring districts on a quarterly basis, and in the Republic twice a year. Farms providing milk for children, healthcare institutions and sanatoria and processed milk for trade are subjected to a quarterly investigation. -174- 6. Bovine tuberculosis Only sporadic cases are registered in the Republic. Hypersensitivity tests are currently performed on cattle twice a year from six months of age. Positive reactions have not occurred. Suspect animals are slaughtered and a bacteriological examination is carried out. Carcases of dead animals are regularly controlled for pathological changes. Diseases of pigs 7. Porcine brucellosis Strict control of abortions and yearly investigations are planned. The importation of vaccinated pigs into the Republic is prohibited. 8. Trichinellosis In 1995, the situation deteriorated. While in previous years the disease was found mostly in wild boars, last year the incidence among pigs increased sharply and many cases were registered in humans. Major zones of the disease occurred in Sakiai, Radviliskis, Kaunas, Jubarkas, Siauliai and Pasvalys districts, where pigs on large farms were infected. On investigation, it was discovered that rats and cats were infected with trichinellosis. This provides evidence that the disease is mostly transmitted by rodents. In order to localise the disease, new, more strict instructions on trichinellosis control and eradication have been introduced. These provide for the lifting of restrictions only after 12 months have elapsed since the last case of trichinellosis. All slaughtered pigs, coypu and hunted wild boar were tested for trichinellosis. A number of problems have arisen in connection with the destruction of rodents. Poultry diseases Antibody titres of avian infectious bronchitis, infectious laryngotracheitis, infectious bursal disease (Gumboro disease), though not high and constant, were found in the blood of poultry of different ages in most poultry farms in the Republic. Fish diseases No List B fish diseases were registered in 1995. Diseases of horses 9. Equine infectious anaemia In 1995, infectious anaemia of horses was confirmed in 21 districts on private farms, mainly in areas close to or within forests. A total of 74 horses reacted, either positively or doubtfully, to the Coggins test. They were all euthanised. Horse care Only healthy horses from the territories free of infectious disease and having veterinary documents and horse identification cards are imported into Lithuania. Horse owners must obtain permission from the State Veterinary Service. On bringing horses into the country, the owners are obliged to subject them to quarantine on their own farm for 30 days under the supervision of the Veterinary Service. During this period, the necessary testing is completed. Horses for export are kept in quarantine in the stables of their owners for 30 days. Blood testing is conducted by the State veterinary stations. Thirty days later, horses are sent to the State quarantine station. At present, there are two quarantine stations, in Vilnius and Kaunas, established on properly equipped premises. Horses are kept in State quarantine stations for 4 weeks and necessary blood testing and vaccination is carried out. At present, only western-made diagnostic materials are used for blood testing. -175- Four weeks later, if negative results are obtained, horses are released for export. In practical terms, horses undergo examination on two occasions. Veterinary documents for the export of horses are issued by the veterinarians of the State quarantine stations. III. OTHER DISEASES 1. Swine pasteurellosis In 1995, swine pasteurellosis was not registered in country farms. 2. Avian leukosis Vaccination is performed against avian leukosis. 3. Avian salmonellosis (excluding fowl typhoid and pullorum disease) Salmonellosis was diagnosed. On all farms of the Republic a total of about 32,000 poultry died. However, no data are available on the number of clinical cases. -176 - L U X E M B O U R G I.

Dec constatées Stomatite vésiculeuse Maladie vésiculeuse du porc Peste bovine Peste des petits ruminants Péripneumonie contagieuse bovine Dermatose nodulaire contagieuse Commentaires F.P. Nov 0 (date du dernier foyer) Influenza aviaire hautement pathogène (1956) sur certaines maladies de la Liste A Fièvre aphteuse La directive 90/423/CEE, transposée par le règlement grand-ducal du 7 décembre 1992, prévoit l'abandon de la vaccination annuelle préventive dans tous les pays membres. Cette vaccination a été pratiquée systématiquement dans notre pays depuis 1964. La campagne de vaccination qui s'est déroulée pendant l'hiver 1990/91 a été la dernière. De ce fait, la majorité des animaux ne présentent plus d'anticorps contre le virus de la fièvre aphteuse et seraient pleinement réceptifs au cas où une epizootie de fièvre aphteuse viendrait par malheur se propager dans notre pays. Les conséquences, c'est-à-dire l'abattage d'office des cheptels atteints, les mesures de restriction à mettre en œuvre dans ce cas et les limitations voire l'interdiction passagère des échanges, constitueraient pour notre agriculture, qui tire 90 % de son revenu de l'élevage bovin et porcin, une catastrophe nationale dont elle ne se relèverait que difficilement. Les épizooties de fièvre aphteuse qui se sont déclarées en Italie en 1993 et en Grèce en 1994 ont nécessité l'abattage d'office de milliers d'animaux et des restrictions des déplacements et des échanges. Ceci démontre que la réapparition de la fièvre aphteuse est une menace réelle et souligne l'importance des contrôles aux frontières extérieures de l'Union européenne et de la surveillance des échanges intracommunautaires après l'abolition des contrôles aux frontières intérieures. 2. Peste porcine classique Depuis 1987, la collecte des déchets de cuisine pour l'alimentation des porcs est interdite. Etant donné que la peste porcine classique continue de sévir dans l'Union européenne, la vigilance s'impose lors de nos importations de porcs et de porcelets ainsi que dans le commerce de porcs en général. Au Laboratoire de médecine vétérinaire, 3 230 sérums porcins ont été testés. 3. Maladie de Newcastle Les deux foyers diagnostiqués en 1995 ont nécessité l'abattage d'office de 15 volailles. -177 - IL MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Maladie d'Aujeszky Au cours de l'année 1991, la maladie d'Aujeszky avait été diagnostiquée dans quatre exploitations porcines nécessitant l'abattage d'office de 700 porcs. Heureusement aucun nouveau foyer ne s'est déclaré depuis lors. Néanmoins, cette maladie fait peser toujours des menaces graves sur notre cheptel porcin surtout si l'on sait que nous échangeons chaque semaine des porcins de toutes catégories avec nos pays voisins. Les animaux les plus dangereux pour l'introduction de cette maladie sont les porcelets destinés à l'engraissement, fournis par des marchands luxembourgeois ou étrangers et qui ont une provenance très hétérogène quant à leur statut sanitaire concernant la maladie d'Aujeszky. C'est pour cette raison que l'Administration des Services vétérinaires a élaboré un plan de dépistage et d'éradication de la maladie d'Aujeszky. Ce plan, approuvé par la Commission, par la décision 93/200/CEE nous permet d'exiger des garanties supplémentaires fixées dans la décision 93/244/CEE du 2 avril 1993 lors de l'introduction de porcs d'élevage et de rente. Notre pays importe chaque année des milliers de porcs de boucherie, des porcelets destinés à l'engraissement ainsi que des animaux destinés à l'élevage. Les mêmes flux existent en sens inverse, mais toutefois à une échelle beaucoup plus réduite. Le plan de dépistage et d'éradication a été rendu obligatoire par le règlement ministériel du 28 janvier 1993. Il comporte les mesures suivantes: 1) Prises de sang obligatoires chez tous les animaux de reproduction (truies et verrats) dans toutes les exploitations d'élevage n'ayant pas encore le statut "d'exploitation officiellement indemne" pour une analyse sérologique par la méthode ELISA. 2) Abattage d'office des animaux séropositifs avec indemnisation des propriétaires et mise sous séquestre de l'exploitation concernée. 3) Dans les années suivantes, des prises de sang chez 25 % des animaux reproducteurs ; ces prises de sang pouvant être faites à l'abattoir lors de l'abattage des truies de réforme. 4) Abattage d'office de tout le cheptel porcin en cas de manifestations cliniques, confirmées par des examens de laboratoire, avec indemnisation du propriétaire. 5) La vaccination préventive est interdite. Les garanties supplémentaires accordées au Luxembourg par la Commission de la CE sont les suivantes: a) Les animaux de reproduction doivent provenir d'exploitations indemnes de la maladie depuis un an, être isolés pendant 30 jours et présenter une réaction négative lors d'une épreuve sérologique pratiquée après 21 jours d'isolement. b) Les porcelets d'engraissement doivent provenir d'une exploitation indemne depuis 12 mois de la maladie d'Aujeszky et qui fait partie d'un programme de dépistage et d'éradication, ou avoir été isolés pendant 30 jours et être soumis à une épreuve sérologique avec résultat négatif. Ces porcelets ne peuvent être destinés qu'à l'engraissement et ne peuvent quitter leur exploitation d'engraissement que pour être conduits à l'abattoir. c) Les porcs de boucherie destinés à l'abattage supplémentaire. immédiat ne sont soumis à aucune exigence Tout ce train de mesures permettra d'éradiquer la maladie au Luxembourg, de protéger nos exploitations d'élevage et d'ouvrir à nos éleveurs les marchés de nos pays voisins pour leurs animaux de reproduction tout en préservant les intérêts de nos engraisseurs. En plus, il permettra à nos abattoirs de s'approvisionner chez nos voisins en porcs de boucherie destinés à l'abattage immédiat. -178- La campagne de dépistage et d'éradication a été rendue obligatoire par le règlement ministériel du 28 janvier 1993 ; elle a fourni à ce jour les résultats suivants: Objet de dépistage sérologique Résultats positifs Nombre d'exploitations Nombre d'échantillons Nombre d'exploitations Nombre d'échantillons 1993 246 7 932 5 7 1994* 262 3 435 2 2 1995 281 3 337 16 En 1994, 25 % des animaux d'élevage (truies et verrats) ont été testés. * * Exploitation en voie d'assainissement. Rage Au mois d'octobre 1994, un cas de rage avait été diagnostiqué chez un renard à Erpeldange/ Remich, dans le sud-est du pays. Cette réapparition de la rage chez le renard a fortement préoccupé l'Administration des Services vétérinaires puisque le dernier cas diagnostiqué chez le renard remontait à octobre 1991, donc à plus de trois ans. Malheureusement, la situation s'est encore agravée en 1995, car 15 cas de rage ont été diagnostiqués, à savoir : 9 renards, 5 bovins et 1 mouton. Tous ces cas se situent dans le sud-est du pays, principalement dans le canton de Remich. Les campagnes de vaccination des renards par le largage d'appâts contenant le vaccin, organisées à partir de l'année 1990, avaient permis de faire régresser de façon spectaculaire le nombre des cas de rage. L'évolution a été la suivante: 1989 1990 1991 1992 1993 1994 1995 : : : : : : : 140 cas de rage, dont 67 cas chez le renard 64 cas de rage, dont 35 cas chez le renard 16 cas de rage, dont 8 cas chez le renard 2 cas de rage, dont aucun cas chez le renard 1 cas de rage, dont aucun cas chez le renard 1 cas de rage, chez un renard 15 cas de rage, dont 9 cas chez le renard Pendant l'année 1995, deux campagnes de vaccination par hélicoptère avec le vaccin " Raboral " ont eu lieu. La première pendant la semaine du 15 au 19 mai et la deuxième pendant la semaine du 18 au 23 septembre.

Paratubcrculose Cette maladie s'est fortement propagée durant les dernières années, surtout par l'augmentation du nombre des vaches allaitantes et les importations massives de bovins de races à viande. En 1995, l'administration des Services vétérinaires a établi un programme de dépistage et d'éradication volontaire pour permettre à des éleveurs qui le souhaitent de qualifier leur cheptel en vue de pouvoir offrir des garanties supplémentaires à leurs acheteurs de bêtes d'élevage et de rente. A cet effet le Laboratoire de médecine vétérinaire a acheté un appareil pour appliquer la méthode PCR avec laquelle on peut détecter l'agent de la paratuberculose, le bacille de Johne, avant que ces animaux montrent des signes cliniques de la maladie. De cette façon on peut détecter et éliminer ces animaux qui sont responsables du maintien de cette insidieuse maladie qu'est la paratuberculose dans le troupeau. En 1995, 1 618 échantillons de sang, provenant de 16 exploitations différentes, ont été analysés. 77 échantillons ont montré une réaction positive. 1 603 échantillons de matières fécales, provenant des mêmes exploitations, ont été examinés par la méthode PCR. 76 résultats positifs ont été constatés. La plupart des bovins ayant montré une réaction positive ont été abattus entretemps. En 1995, 13 bovins ont été abattus d'office nécessitant une dépense de 320 981 francs (LUF) pour l'indemnisation des propriétaires. Maladies 4. des bovins Brucellose bovine En 1994 aucun foyer de brucellose n'a été diagnostiqué dans notre pays. C'était la première année sans foyer de brucellose depuis 1985. Malheureusement un nouveau foyer a été diagnostiqué au mois de février 1995 et 141 bovins ont été abattus d'office. La cause la plus probable est l'importation tout à fait légale déjeunes bovins en 1992. Grâce au dépistage rapide et aux mesures énergiques prises par l'Administration des Services vétérinaires, la maladie ne s'est pas propagée à d'autres troupeaux. Les mesures de prévention et de contrôle continuent à être appliquées. C'est ainsi qu'en 1995 les exploitations laitières ont été testées à deux reprises. En plus tous les animaux âgés de plus de deux ans, provenant des cheptels ne livrant pas de lait aux laiteries, sont testés pendant l'hiver 1995/1996. D'autre part le sang de tous les animaux d'élevage et de rente âgés de plus de 18 mois, destinés aux échanges, est analysé pour la brucellose. Vu le grand nombre d'animaux exportés, cette opération constitue un screening toutes les exploitations du pays. 5. couvrant pratiquement Leucose bovine enzootique Des campagnes de détection pour la leucose bovine enzootique ont été entreprises pendant les hivers 1988/89 et 1989/90 englobant toutes les exploitations détenant des bovins. Les résultats de toutes les analyses sérologiques ont été négatifs. Ces résultats favorables nous ont permis de qualifier tous nos cheptels bovins comme étant indemnes de leucose et d'obtenir pour tout le pays le statut de "pays officiellement indemne" ce qui facilite beaucoup nos exportations de bovins d'élevage. -180 - Pour maintenir ce statut, nous devons soumettre chaque année environ un tiers de nos cheptels à un test de dépistage. C'est ainsi que les cheptels de tous les producteurs livrant leur lait à "Procola", "Corelux" et "Ekabe", au nombre de 494, ont été contrôlés. En outre 6 367 échantillons de sang ont été testés. Un seul animal a présenté un résultat douteux et a été abattu d'office. 6. Encéphalopathie spongiforme bovine Jusqu'ici aucun cas d'encéphalopathie spongiforme bovine (BSE) n'a été signalé dans notre pays. La BSE a été ajoutée à la liste des maladies à déclaration obligatoire par le règlement ministériel du 9 août 1990, ce qui permet à l'Administration des Services vétérinaires de prendre des mesures d'ordre sanitaire. En plus toutes les têtes de bovins qui parviennent au Laboratoire de Médecine vétérinaire pour suspicion de rage, mais chez lesquelles la rage n'a pas été confirmée, sont examinées pour rechercher la BSE. Jusqu'à ce jour toutes avec un résultat négatif. D'autre part, dans le cheptel bovin luxembourgeois, il n'y a aucun animal né au Royaume-Uni. Maladies des ovins et caprins 7. Maedi-visna L'Administration des Services vétérinaires a mis sur pieds, sur base volontaire, un programme de dépistage et d'éradication de cette maladie à évolution lente. L'action commencée en 1990 a été poursuivie en 1995 et 294 moutons, appartenant à 12 cheptels, ont été soumis à une prise de sang pour détecter la présence d'anticorps contre le virus visna-maedi. 5 résultats positifs ont été enregistrés dans la même exploitation. Maladies des 8. volailles Tuberculose aviaire Un foyer de tuberculose aviaire a été déclaré dans le nord du pays, nécessitant l'abattage d'office de 15 volailles. La tuberculose aviaire est une maladie qui est encore sporadiquement constatée chez des petits troupeaux de volailles vivant à l'extérieur et il semble que les oiseaux sauvages jouent un rôle dans sa propagation. Maladies des 9. lagomorphes Maladie hémorragique virale du lapin Les premiers cas de cette maladie dans notre pays ont été diagnostiqués au Laboratoire vétérinaire au début de l'année 1990. Par règlement ministériel du 9 août 1990 cette maladie à la liste des maladies à déclaration obligatoire, afin de permettre à l'Administration vétérinaires de prendre des mesures de lutte. Ainsi il a été décidé que tous les lapins des participent aux expositions cunicoles doivent être vaccinés contre cette maladie. de médecine a été ajoutée des Services élevages qui Maladies des abeilles 10. Loque américaine Après les 2 foyers de la loque américaine diagnostiqués dans le canton de Remich en 1992, aucun nouveau foyer n'a été constaté depuis lors. - 181 - Cette maladie doit être combattue énergiquement, car il n'existe aucun traitement médicamenteux valable, et seule l'application de mesures hygiéniques par des apiculteurs qualifiés et motivés peut venir à bout de ce redoutable fléau. Pour cette raison, la Fédération des Unions d'Apiculteurs Luxembourgeoise (FUAL) a recours aux sendees d'un vétérinaire qui est lui-même un fervent apiculteur et qui a acquis la compétence nécessaire pour conseiller et guider les apiculteurs à travers tout le pays. En 1995, 153 échantillons de miel ont été examinés au Laboratoire de médecine vétérinaire pour rechercher les spores de Bacillus larvae, l'agent causal de la maladie. Tous ces échantillons ont donné un résultat négatif. Varroase Tout comme durant les années précédentes, la varroase a continué à être présente à l'état endémique et il faut s'apprêter à vivre avec cette maladie qui provoque des pertes surtout indirectes, par l'affaiblissement des colonies d'abeilles et les rendant ainsi plus réceptives à d'autres maladies. Pour cette raison il est fortement recommandé de soumettre les colonies à un traitement préventif en automne et d'appliquer surtout des mesures hygiéniques. Ainsi en 1995, un montant de 748 604 LUF a été dépensé par l'Administration des Services vétérinaires pour l'acquisition de 8 000 rubans d'apistan qui ont été distribués aux apiculteurs par l'intermédiaire des experts apicoles et des délégués de la FUAL. De leur côté, les apiculteurs ont contribué au coût des médicaments à raison de 50 LUF par colonie traitée. Comme un certain nombre d'apiculteurs préfèrent traiter leurs colonies à l'aide d'acide formique (Ameisensâure), 288 litres de ce produit ont été mis à leur disposition pour un montant de 23 847 LUF. -182- M A D A G A S C A R MALADIES DE LA LISTE A Aperçu général Maladies présentes en 1995 Total 1994 81 7 37 Dennatose nodulaire contagieuse Peste porcine classique Maladie de Newcastle Maladies n'ayant jamais été Total 1995 72 6 18 Jan 14 0 0 Fev 6 0 1 Mar 14 4 3 Avr 4 1 0 Mai 3 0 0 1995 Jun Jul 11 1 0 1 0 3 F.P.

Le seul moyen de lutte pratiqué est le douchage périodique des animaux. La vaccination contre cette maladie n'est pas pratiquée à Madagascar. 2. Peste porcine classique L'intensification des méthodes de prophylaxie médicale a permis de diminuer le nombre de foyers. En effet, le taux de vaccination a augmenté cette année. 3. Maladie de Newcastle Des foyers ont été signalés dans des exploitations de type "basse-cour" situés dans des villages d'accès difficile. Néanmoins, des mesures de police sanitaire ont été prises : ceinture vaccinale autour des foyers, interdiction de circulation des volailles et produits dérivés hors des zones infectées. -183- M A L A W I I.

Contagious bovine pleuropneumonia As contagious bovine pleuropneumonia threatens Malawi, the Department of Animal Health and Industry has prepared a contingency plan including increased surveillance in the border areas in order to prevent the transboundary spread of the disease into the country. Veterinary personnel at all levels in the areas at immediate risk have received refresher training on contagious bovine pleuropneumonia. Publicity campaigns at village level (in areas at immediate risk) have been conducted through the use of posters and meetings with livestock farmers and local leaders. The activities are funded by the FAO through a Technical Cooperation Project (TCP). 3. Lumpy skin disease There were relatively fewer lumpy skin disease outbreaks than in 1995. The sporadic outbreaks were evenly spread throughout the year. 4. African swine fever African swine fever appears to be assuming endemic status also in the Southern and Northern regions of Malawi, as more outbreaks continue to be observed in these areas where the disease was not previously considered to be endemic. 5. Newcastle disease There was a notable decrease in the number of Newcastle disease outbreaks during 1995. Given a vaccination coverage of just over 1 million in a country with an estimated poultry population of about 13 million, it is very unlikely that vaccine coverage has any influence on the number of outbreaks in a particular year. It is perhaps logical to assume that other factors (yet to be established) determine the nature of outbreaks. 11-94 01-94 12-94 12-94 -184- II. LIST B DISEASES Diseases of multiple 1. species Anthrax Malawi has maintained its anthrax-free status. Laboratories are constantly on the alert to report any suspicious large square-ended rods with a pink capsule observed when carrying out routine examination of Giemsa-stained blood smears. 2. Heartwater Heartwater continued to occur sporadically. 3. Rabies It does appear that rabies will remain endemic as long as vaccine coverage is low. The WHO has promised to fund a nationwide mass dog vaccination if the country can provide information pertaining to dog ecology. Dog ecology in Malawi has been suggested as a research topic and this is still under debate. It has been suggested that for Malawi to control rabies effectively, at least 8 0 % of the dog population should be vaccinated. The sylvatic cycle of rabies is apparently not important in the country. Diseases of cattle 4. Bovine babesiosis There is some evidence to suggest that there is endemic stability to babesiosis in the country, and possibly to other tick-borne diseases such as East Coast fever. 5. Bovine tuberculosis Bovine tuberculosis remains endemic in the Central and Northern regions of Malawi. Tuberculosis cases are largely reported during meat inspection. The country has no policy on bovine tuberculosis control, other than meat inspection to prevent its spread to humans. 6. Enzootic bovine leukosis The absence of pathognomonic signs of enzootic bovine leukosis means that the disease can only be recognised through active surveillance. The fact that the disease was not reported was probably because there was no active surveillance to detect it serologically. Diseases of poultry 7. Infectious bursal disease (Gumboro disease) The ever-increasing importance of infectious bursal disease in the country justifies a much wider vaccination coverage than is currently the case. III. O T H E R DISEASES The fortnightly strategic dipping from mid-November to the end of April went through its second year of implementation. The Dipping Commission will convene soon to review the new strategy. 1. Blackquartcr (blackleg) Sporadic blackquartcr outbreaks occurred in the areas where the disease is known to be endemic and it does not appear to have spread to new areas. 2. Canine distemper Canine distemper was highly suspected of having killed a number of dogs in Mzuzu Agricultural Development Division in the Northern region of Malawi, but this was never confirmed. -185- M A L A Y S I A ( P E N I N S U L A R ) INTRODUCTION There has been a progressive increase towards monitoring and control of contaminants in food of animal origin since 1975. Fresh milk was the first commodity given due attention in view of its highly perishable nature. Abattoir hygiene in local establishments and imported products from selected countries and cold rooms were added to the programme. Monitoring of various food preparations in retail outlets is a recent activity that requires considerable attention in the improvement of food handling. The Department of Veterinary Services is responsible for food quality from the farm level to the abattoir as well as within the food processing plants. In view of the increased public health activities, the Department of Veterinary Services was reorganised in October 1995. The creation of the Veterinary Public Health Division is expected to provide a more intensive coverage in reducing contaminants to safe levels. The master plan for Food Safety and the application of the Hazard Analysis: Critical Control Point (HACCP) was documented in November 1995. It is a long term plan meant for the public and private sectors to implement towards increasing food safety. I.

In June 1995, the disease was reported in the southern states of Negri Sembilan, Malacca and Johore, a situation which was new since these States had not had the disease since post war. Only cattle and buffaloes were affected in all the outbreaks in the reported year and three strains were isolated: Asia 1, A and O. Foot and mouth disease virus type A last reported in 1973 was detected in 2 2 2 2 12-94 1973 12-94 08-94 10-94 11-94 -186 - animals at the quarantine station in Padang Besar (in the State of Perlis) in July which subsequently spread to Penang. Perak and Kedah. Type O was also detected in cattle at the quarantine station. In the other areas type Asia 1 continued to be the main strain implicated. Movement of infected animals was the main cause of the spread to areas in the south and new foci in the north. Two strategies were undertaken to alleviate the problem. • Accreditation of cattle suppliers from the exporting country. Cattle sourced from these suppliers should comply with the conditions agreed upon by both countries. The main objective is to ensure that the origin and health status of the animals are known. Upon arrival at the quarantine station in Malaysia the animals are grouped in yards according to the source. This is to ensure that if animals are infected, the destruction would be confined to animals in the group only and not all animals in the station. • More cattle are obtained from integrated farming areas in the peninsula to meet the local demand for beef. Monitoring movement of animals through road blocks in endemic areas has become a routine feature in efforts to curtail the problem. 2. Classical swine fever (hog cholera) Field reports concerning classical swine fever have portrayed a change from the typical clinical picture of swine fever. The occurrence of the disease is closely associated with unvaccinated runts which had chronic respiratory problems prior to death. 3. Newcastle disease Sporadic outbreaks of the disease were reported in various parts of the country whereby the disease was identified mainly in commercial broilers. The outbreaks were attributed to improper vaccination programmes whereby immunization of chicks were not followed up by a booster at a later age. II. LIST B DISEASES Lnseases of cattle 1. Haemorrhagic septicaemia Outbreaks of the disease were reported in animals that were not vaccinated. Both cattle and buffaloes were affected. The disease was previously reported mainly in buffaloes since this group of animals is difficult to ac-inate annually. However, in 1995, an equal number of cases was reported in cattle. The reason was failure to immunize the cattle. ¿\s from December 1995, the oil adjuvant bacterin which has been used to immunise the cattle and buffalo heids was replaced by a double adjuvant bacterin which is produced by the Veterinary Research Institute. The new bacterin which requires only 2 ml (as compared to 5 ml with the oil adjuvant) per animal is given annually to cattle or buffaloes aged 4 months and above. In the event of an outbreak, in-contact animals and animals within 5 miles radius of the outbreak are vaccinated with an alum bacterin together with the double adjuvant bacterin. Diseases of sheep and goats 2. Caprine and ovine brucellosis (excluding B. ovis) Brucellosis in sheep was first detected in 1994, which was brought into the country through imports. Subsequently, sheep and goats in government-owned farms and those which obtained animals from the former were screened for brucellosis by the rose bengal plate test. Ever since the programme started, a total of 9,057 goats and 48,783 sheep were tested and 45 (0.4%) goats and 1,983 (4.06%) sheep were positive. Infected animals were destroyed and farmers compensated. -187- Vaccination is not practised and the disease is monitored by serological screening and investigations into causes of abortions in sheep and goats, especially in farms where the disease has been identified. Diseases of poultry 3. Infectious bursal disease (Gumboro disease) Infectious bursal disease remained one of the most important poultry diseases incurring losses in layers, broilers and breeders. Vaccines used were imported and did not seem to confer sufficient protection in farms where the outbreaks occurred. The Veterinary Research Institute worked on a local isolate to develop a vaccine for domestic use. Trials have shown the vaccine to be effective in protecting birds against the field virus. 4. Marek's disease Cases reported for this disease outnumbered all the other poultry diseases. Outbreaks occurred in layers, broilers and village chickens. Improper handling of vaccines or failure to vaccinate were the possible reasons for the occurrence. 5. Pullorum disease (.Salmonella pullorum) The National Pullorum Disease Control Programme remains to be a voluntary scheme but most breeder farms are participants of the programme. Five cases reported for the year were in replacement pullents, broiler chicks and village chickens. Mortalities recorded were as high as 60%. Breeders however remain to be free from Salmonella pullorum. - 188- M A L I I.

Dermatose nodulaire contagieuse Un seul foyer de dermatose nodulaire contagieuse a été enregistré, dans le district des Bamako. Dans ce foyer, 4 malades ont été observés sans aucune mortalité. Il convient de rappeler que 28 foyers de dermatose nodulaire contagieuse avaient été enregistrés en 1994, avec 5 319 malades et 62 morts. -189- II. MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Charbon bactéridien (fièvre charbonneuse) Deux foyers de charbon bactéridien ont été enregistrés, l'un à Ségou, l'autre à Tombouctou. A Tombouctou (Goundam) la maladie a sévi exclusivement chez les asins. 2. Rage 20 cas de rage canine ont été confirmés par le laboratoire sur 44 suspectés. Maladies des bovins 3. Brucellose bovine Le sérodiagnostic a permis de mettre en évidence l'infection brucellique chez les bovins dans certaines localités. 4. Tuberculose bovine Les lésions spécifiques de la tuberculose ont été observées sur des carcasses de bovins, d'ovins et de caprins dans toutes les régions d'élevage du pays. Les saisies totales ont porté sur 172 carcasses de bovins et 6 carcasses d'ovins et de caprins. Les résultats de l'intradermotuberculination effectuée dans la zone périurbaine de Bamako sur 1 064 bovins montrent un taux de 10,90 % d'animaux qui ont réagi à la tuberculine. 5. Pasteurellose bovine (septicémie hémorragique) La maladie a été enregistrée dans les régions de Kayes, Sikasso, Ségou, Mopti et Tombouctou. III. AUTRES MALADIES Maladies communes à plusieurs 1. espèces Charbon symptomatique 13 foyers de cette maladie, avec 419 malades dont 240 morts ont été enregistrés. Maladies des ovins et caprins 2. Pasteurellose des petits ruminants 7 foyers de pasteurellose ovine et caprine ont été enregistrés. Dans ces localités, 216 malades et 93 morts ont été dénombrés. Outre les maladies ci-dessus citées, qui sont réputées légalement contagieuses au Mali, d'autres, telles que les trypanosomoses et les parasitoses gastro-intestinales, ont été enregistrées dans les différentes régions. Les mesures de lutte prises ont permis de maîtriser et d'éteindre tous les foyers des maladies indiquées. - 190 - MAROC I.

Le dernier cas enregistré remonte au mois de septembre 1992 au niveau de la province de Settat. Situation médicale La vaccination antiaphteuse bovine a été poursuivie en 1995 et a touché 1 250 000 bovins à l'aide du vaccin monovalent contenant la valence 0 2 9 2 Recherches et études épidémiologiques Les études séro-épidémiologiques se sont poursuivies durant l'année 1995 avec la collaboration du Laboratoire mondial de référence de l'OIE pour la fièvre aphteuse (Pirbright, Royaume-Uni). Ces études ont pour objectifs : 2. - d'assurer aux cadres nationaux une formation en matière de diagnostic sérologique de la fièvre aphteuse ; - de mener les investigations quant à une éventuelle circulation du virus de type O au Maroc. Clavelée Des foyers isolés de clavelée, principalement chez les jeunes ovins et les adultes ayant échappé à la vaccination, ont été enregistrés au cours de 1995 dans certaines provinces du royaume (notamment celles de l'oriental) à la faveur des déplacements d'animaux. Les mesures sanitaires prises sont l'isolement et la séquestration des troupeaux touchés et une vaccination en anneau. La vaccination anticlaveleuse a été poursuivie en 1995 par l'exécution d'une campagne généralisée à l'ensemble du territoire national. Le bilan global de cette opération fait état de 12 797 129 ovins vaccinés contre cette maladie, soit un taux de couverture vaccinale de 83,22 %. -191 - 3. Peste équine Suite à la procédure initiée par la Direction de l'élevage au mois de mai 1995 auprès de l'OIE et de la Commission vétérinaire de l'Union européenne pour le recouvrement par le Maroc du statut de pays indemne de peste équine, et suite à la mission communautaire du mois de juin, le Maroc a recouvré son statut de pays indemne de cette maladie, conformément aux recommandations du Code zoosanitaire international de l'OIE. La notification en a été publiée le 7 juillet 1995 dans les Informations sanitaires de l'OIE (vol. 8, n° 24, p. 72). Par ailleurs, l'Union européenne a adopté en ce sens le 19 juillet 1995 une Décision qui a été notifiée le 20 juillet 1995 à ses Etats membres. II. MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Rage La lutte contre cette zoonose a été poursuivie et renforcée en 1994 conformément au Plan national de lutte contre la rage. Les mesures de prophylaxie médicale ont été marquées par l'organisation d'une campagne nationale de vaccination des chiens ayant un propriétaire (notamment en milieu rural) durant le mois d'octobre 1995. Les réalisations enregistrées font état de 250 000 chiens vaccinés. Parallèlement, les activités de prophylaxie sanitaire ont également été poursuivies : 62 544 chiens ont été abattus et détruits durant l'année 1995. Par ailleurs, dans le cadre de la lutte contre cette zoonose, un séminaire a été organisé à Rabat les 11 et 12 décembre 1995 en collaboration avec le ministère de la santé publique et l'Organisation mondiale de la santé. Ce séminaire avait comme principaux objectifs : - la sensibilisation et l'information de tout le personnel impliqué dans la lutte contre la rage ; - le renforcement de la collaboration et la coordination intersectorielle (locale, régionale, centrale) et interdépartementale (santé publique, agriculture, intérieur). Maladies des bovins 2. Brucellose bovine En application du plan national de lutte contre la brucellose, des actions d'identification et de vaccination des velles dans les zones contaminées ont été programmées et exécutées de 1989 à 1995 selon un rythme annuel de l'ordre de 50 000 velles vaccinées par an. L'évaluation du plan dans sa dernière phase a montré que les objectifs préalablement fixés en matière de couverture vaccinale n'ont pas été atteints. C'est ainsi que des travaux visant à revoir la situation de cette maladie ont commencé en octobre 1995. Ces travaux, conduits en collaboration avec la FAO, permettront de mettre en place la nouvelle stratégie de lutte à adopter. Ils comprennent essentiellement l'équipement des laboratoires vétérinaires régionaux, la formation de leur personnel, l'exécution d'une enquête épidémiologique et la sensibilisation des éleveurs. Maladies des 3. abeilles Varroase Dans le cadre des efforts visant le contrôle de cette maladie, une campagne de sensibilisation et d'information des éleveurs dans ce domaine a été organisée en janvier 1995. Elle a porté sur le traitement de 88 428 ruches, dont 36 703 modernes et 51 715 traditionnelles, correspondant à un effectif d'environ 30 % du cheptel apicole national. Parallèlement, l'étude de la varroase et de la biologie du parasite (Varroa jacobsoni) s'est poursuivie durant l'année 1995. Les activités ont porté notamment sur la poursuite de l'étude sur la morphologie et la biologie du parasite, ainsi que sur l'épidémiologie de cette maladie au Maroc. -192- M A U R I T A I M I E INTRODUCTION Depuis la restructuration, fin 1993, du ministère du Développement rural et de l'Environnement (MDRE), les fonctionnaires de l'ancienne direction de l'Elevage sont affectés soit à la direction du Développement des Ressources agro-pastorales (DRAP), soit dans les délégations régionales du MDRE, soit à la direction de la "Recherche - Formation - Vulgarisation" (DRFV). Au sein de la DRAP, qui compte cinq services et dix divisions, les activités de conception et de suivi des programmes vétérinaires sont à la charge du service "Amélioration des Ressources animales" et reviennent plus spécifiquement à sa division "Santé animale". L'exécution des programmes de prophylaxie et de l'ensemble des tâches de santé publique vétérinaire est assurée par les délégations régionales du MDRE, dont bon nombre ne sont pas dirigées par des vétérinaires mais par des agronomes ou par des forestiers. Ces délégations ne disposent pas de service spécifique "Santé animale", mais d'un service "Développement des Ressources agro-pastorales" s'occupant de toutes les préoccupations du monde rural. Pour que tous les agents de base soient en mesure de répondre aux interrogations des ruraux, une formation à la polyvalence est entreprise à la DRFV, dans le cadre d'un programme national de vulgarisation financé par un prêt de la Banque mondiale. Le système en vigueur ("Formation et Visite") prévoit, au sein de chacune des délégations, un technicien spécialiste de l'élevage, qui est en fait le seul interlocuteur régional de la santé publique vétérinaire. Celui-ci rend compte de ses activités au Délégué régional, qui, à son tour, rend compte au Cabinet du ministre. La division "Santé animale" de la DRAP se trouve ainsi "hors circuit" et ne dispose que de trop rares informations en provenance des wilayas ; les rapports hebdomadaires des Délégués, qu'elle peut se procurer au Cabinet du ministre, ne donnent pas toujours les informations de base nécessaires à l'établissement des rapports mensuels à adresser à l'OfE, d'où une transmission irrégulière de ces rapports. Au cours de l'année 1996, il est envisagé de créer, au sein de chaque wilaya, un service spécifique de santé publique vétérinaire rendant compte mensuellement de l'état sanitaire des troupeaux à la division "Santé animale" de la DRAP. Parallèlement, dans le cadre du projet PARC, il est prévu de procéder à une étude préalable à la mise en place d'un réseau zoosanitaire national utilisant au mieux les compétences et les moyens des services privés et publics.

Péripneumonie contagieuse bovine et opérations de séro-surveillance de la peste bovine Pour la péripneumonie contagieuse bovine (PPCB), l'utilisation, lors des campagnes annuelles de prophylaxie, d'un vaccin bivalent (peste bovine / PPCB) fait que le taux de prévalence est indirectement connu lors de la séro-surveillance de la peste bovine. Pour la peste bovine, les opérations de séro-surveillance ont débuté en 1990. Les prélèvements ont été effectués, par le service de virologie du Centre national d'élevage et de recherches vétérinaires, dans les trois wilayas les plus importantes en matière d'élevage bovin. Les analyses ont été réalisées par le Laboratoire central de pathologie animale de Bingerville. En utilisant l'épreuve ELISA sur l'ensemble des sérums analysés, la moyenne des résultats exprimés en pourcentage de positivité vis-à-vis de la peste bovine a été de : Années Pourcentage de positivité vis-à-vis de la peste bovine 1989/1990 57,28 1990/1991 56 1991/1992 54 1992/1993 27 N.B. : En 1991/1992, le taux déjeunes animaux possédant des anticorps dirigés contre le virus bovipestique était extrêmement faible. En 1992/1993, le taux était relativement élevé chez les animaux âgés de plus de trois ans (76 %) et très faible chez les jeunes (9,2 % chez les animaux âgés de moins d'un an). Ces résultats révèlent un taux de couverture insuffisant, en particulier sur les animaux de moins de deux ans. Un pourcentage très faible des troupeaux tout venant est protégé : 11,5 % en 1990, 9 % en 1991, 11,5 % en 1992, 7 % en 1993 et 0 % en 1994, année pour laquelle aucun des troupeaux étudiés n'était protégé à 80 %. Au cours de la campagne de prophylaxie 1994/1995 : 25 % du cheptel a été vacciné (281 877 vaccinations peste/PPCB). Compte tenu de l'apparition de foyers de PPCB et du faible taux d'immunité constaté, l'objectif fixé pour la campagne en cours est d'atteindre chez les jeunes bovins un taux de séro-conversion vis-à-vis de la peste d'au moins 80 % (avec un pourcentage de vaccination de 100 % chez les jeunes). Cette campagne bénéficie d'un fonds d'urgence mis à disposition par l'Union européenne dans le cadre du projet PARC qui doit débuter en mars 1996. Dans le cadre de ce projet, il est prévu que les vétérinaires privés pourront participer à l'exécution des campagnes de vaccination par l'octroi d'un mandat sanitaire. Le contrôle de la qualité de leurs prestations reste du domaine de l'Etat. La séro-surveillance permettra de vérifier la qualité de leurs prestations ; elle sera assurée par le Centre national d'élevage et de recherche vétérinaire, qui sera équipé pour cela par le projet PARC. 3. Fièvre de la Vallée du Rift Bien que cette maladie n'ait pas fait l'objet de déclaration au cours de l'année, il est fortement probable qu'elle continue de provoquer des avortements chez les petits ruminants de la vallée du fleuve Sénégal. Le laboratoire national ne dispose pas de moyens suffisants pour conduire des enquêtes de suivi épidémiologique. Nous tenons à rappeler ici l'importance de cette suspicion de maladie qui concerne tous les pays riverains du fleuve. -194- II. MALADIES DE LA LISTE B 1 Fièvre charbonneuse Malgré les mesures prises, 78 580 vaccinations effectuées dans les zones d'endémie au cours de la campagne annuelle de prophylaxie, trois foyers de fièvre charbonneuse ont été signalés en octobre dans la moughataa de Mounguel (wilaya du Gorgol), entraînant la perte de 210 petits ruminants, 8 bovins et 2 dromadaires. Le diagnostic clinique a été formellement établi par le vétérinaire, chef de service DRAP de Kaédi. Les mesures prises (destruction des cadavres et vaccination des cheptels dans les foyers et à leur périphérie) ont permis d'enrayer la mortalité. 2 Gale du dromadaire Les grandes distances parcourues par les troupeaux à la recherche de pâturages font que cette maladie sévit à l'état endémique dans toutes les provinces. Insuffisamment traitée lors de la transhumance en fin d'année civile dans les wilayas du Sud, la gale du dromadaire est de nouveau signalée de janvier à mai dans le Tiris Zémour et le Daklet Nouadhibou, où l'encadrement vétérinaire beaucoup moins dense ne permet plus un suivi rapproché des animaux. Les pertes économiques que cette maladie entraîne sont considérables. Notre impuissance face à cette situation nuit beaucoup à l'image de notre profession. -195- M O Z A M B I Q U E INTRODUCTION The peace prevailing since 1992 constitutes an important factor which enhances the livestock development now observed in the country. Generally, there is an increase in the number of almost all livestock species. In 1995, there was an increase of 2 2 % in cattle, 7 5 % in pigs and 5 0 % in small ruminants, compared to the 1994 figures. The main activity of the National Directorate of Livestock (DINAP) was concentrated in the livestock restocking programme, as the country needs to build up livestock numbers in order to recover its livestock industry. As part of such an important programme, a national seminar was held in Inhambane to discuss ways for a better strategy to implement the current restocking programme. In 1995, a number of financing Agencies and NGOs were involved in supporting the purchase of animals, mainly in importing cattle and small ruminants. The main target group of the restocking programme is the family sector. However, private farmers have also been involved and used as 'multiplication centres' to increase the turnover rate of livestock population in the country. This was particularly emphasised in the case of cattle, since they can quickly reproduce under improved management in the hands of the commercial sector. The privatisation programme of the state farms continued to take place in order to promote livestock production in a much more cost effective way. I.

To prevent reintroduction of the disease from neighbouring countries, vaccination in the areas exposed to this danger is also compulsory. However, since 1985 no outbreaks have been reported in the country. 1994 1994 1994 1994 1994 -196- 2. African swine fever As in the previous year, the disease prevalence in livestock continued to be characterised by the occurrence of outbreaks of African swine fever in some of the southern, central and northern provinces. This disease continued to decimate the pig population and thus became one of the biggest concerns to the veterinary authorities. In the southern region of the country, namely Maputo, Gaza and Inhambane provinces, the first outbreaks were registered in 1994 and continued affecting these provinces during 1995. There were also outbreaks of this disease notified in Sofala, Nampula and Zambezia provinces in the central and northern regions of the country. The dissemination of the disease is facilitated by the difficulties experienced by the veterinary authorities in applying effective control measures such as stamping out, due to the scarcity of financial resources for compensation. The measures taken to control the disease were restrictions on the movement of pigs and pork products and advice to farmers to slaughter their animals at the slaughterhouse, where laboratory technicians take blood samples for diagnosis. Due to the current disease situation, the planned restocking project with pigs has been delayed. 3. Newcastle disease Newcastle disease is recognised as being endemic throughout the country. Although the exact number of affected birds is not known, it is believed that thousands of birds are killed each year in the country. In the year under analysis, Maputo, Inhambane, Tete, Nampula and Manica provinces were severely affected by the disease. The number of outbreaks in the family sector is believed to be high but data is not available to quantify this. The veterinary authorities are currently making an effort to introduce a thermostable vaccine for the control of Newcastle disease in the family sector. II. LIST B DISEASES 1. Anthrax Anthrax and blackquarter have not been reported for some years but the threat is still present considering the situation in the neighbouring countries, where some cases have been reported in game animals. In Zambezia province, vaccination against these diseases is not practised. 2. Heartwater Tick-borne diseases occur throughout the country but their importance varies from region to region. Heartwater is of importance in some areas where incidence of Amblyomma is high. The control strategy for tick-borne diseases is mainly based on the application of acaricides and this is usually carried out once a month. 3. Rabies The persistence of rabies foci in urban areas as well as in rural areas has forced the veterinary authorities to consider this disease among the list of priorities. During 1995, there were a total of 18 cases reported in the country. Of these, 9 cases were reported from Maputo, 4 from Manica, 2 from Gaza, 1 from Zambezia and 1 from Niassa. This latter case was reported in a cat, whereas all the others were reported in dogs. In Nampula and Tete provinces there were some suspected clinical cases but no specimens were sent to the laboratory for confirmation. It should be emphasised that, due to the increasing number of human deaths from rabies, Nampula province requires our greatest attention in regard to this disease. The strategy used for the control of rabies is to vaccinate dogs annually in 'free of charge' campaigns. However, lack of financial resources limits the efficiency of the control. -197- Diseases of cattle In the cattle industry, as in previous years, veterinary assistance interventions were severely limited due to degradation of dip tanks. The livestock health situation in the country in 1995 was generally similar to that of previous years. 4. Bovine brucellosis This disease is endemic in the country. Brucellosis control measures in cattle involve vaccination with strain B19 of young females between 4 and 8 months of age. The prevalence of the disease is not well known due to the existence of antibodies from vaccination. Therefore, the National Directorate of Livestock is currently carrying out revision of the regulation relating to the epidemiology and control of the disease. 5. Dermatophilosis In Zambezia province an outbreak of dermatophilosis was reported in cattle, in which 21 out of 315 affected animals died. 6. Theileriosis East Coast fever is limited to the Angonia plateau in Tete province. 7. Trypanosomiasis About two-thirds of the country is infested with tsetse fly. The pathogenic species of trypanosome encountered in Mozambique are Trypanosoma congolense and T. vivax in single or mixed infections in cattle and T. simian in pigs. Prevalence of trypanosomosis in the southern region of the country is low but, to the north of Save River, it varies from medium to high. T. simian outbreaks occur only sporadically. In tsetse infested areas, special attention is given to the control of trypanosomiasis. This is done by means of chemotherapy, which is the method of choice to protect animals in these areas. As knowledge of the current fly distribution and density is very limited a prophylactic scheme using isomefhamidium (Trypamidium) every three months is currently used to protect commercial cattle farms. The animals are treated in February, May, August and November. An additional sanative dose of diminazene aceturate (Berenil 7%) is applied ten days before the treatment in May. In the family sector, only sick animals are treated with a sanative dose. However, due to lack of trypanocides and organisational problems these rules are not strictly followed, namely the periodicity and the transfer of cattle from infested areas to free areas and vice-versa. To date, there is no record of resistance to isomethamidium or diminazene aceturate. Diseases of poultry 8. Infectious bursal disease (Gumboro disease) The main cause of the dissemination of this disease and high mortality in the Maputo and Gaza provinces is the introduction of one-day-old chicks from neighbouring countries. It is also associated with the fact that a major proportion of farmers do not follow the recommended vaccination instructions. III. OTHER DISEASES In 1995, outbreaks of avian leukosis, avian salmonellosis and fowl pox were reported only in Maputo province. The number of birds affected by each of these diseases is not available. In Zambezia province, pasteurellosis caused high mortality in ducks, but the number of birds affected is not available. - 198- N A M I B I A I.

Comments on foot and mouth disease and contagious bovine pleuropneumonia No foot and mouth disease (FMD) occurred during 1995. A cordon fence for FMD control spans the country from east to west: movements of animals and products across this barrier are carefully controlled. Contagious bovine pleuropneumonia (CBPP) appeared to be on the increase. Stock inspection frequencies are very high to the north of this fence, where annual official vaccinations against CBPP and FMD are carried out. Inspection frequencies are lower to the south of the fence, where CBPP and FMD do not occur. Export abattoirs are supervised by official veterinary staff, and imports into Namibia are also controlled. 11-94 12-94 05-94 05-94 02-89 04-94 - 199- N E T H E R L A N D S I.

In 1995. surveys or ongoing surveillance activities were undertaken to obtain animal health status information on the following diseases, pathogens and parasites: Aujeszky's disease in feral pigs, Babesia perroncitoi, Brucella abortus, B. canis, B. suis, bovine spongiform encephalopathy, bluetongue, epizootic haemorrhagic disease, Lyme disease, Newcastle disease, Palyam group viruses, scrapie, Melissococcus pluton, Varroa jacobsoni, Acarapis woodi and Tropilaelaps clareae. None of these diseases were detected. The results of the animal health surveillance and monitoring activities are published in the Ministry of Agriculture's quarterly magazine Surveillance. A review of the animal health surveillance system is being undertaken. In December 1994 a discussion document, Future Animal Disease Surveillance in New Zealand - Development of a Strategy for Animal Disease Sur\>eillance under the Biosecurity Act 1993 was released for public comment. The analysis of the submissions has been completed and policy recommendations are being formulated. Two pest management strategies, one for the control of bovine tuberculosis and one for eradication of Echinococcus granulosus are being developed under the Biosecurity Act 1993. I. LIST A DISEASES Diseases never reported Foot and mouth disease Vesicular stomatitis Swine vesicular disease Rinderpest Peste des petits ruminants Lumpy skin disease Rift Valley fever Bluetongue Sheep pox and goat pox African horse sickness African swine fever Highly pathogenic avian influenza Newcastle disease Diseases reported absent in 1995 (in parentheses: Contagious bovine pleuropneumonia (1864) date of last outbreak) Classical swine fever (1953) II. LIST B DISEASES Diseases of multiple species Aujeszky's disease The Aujeszky's disease virus is notifiable organism under the Biosecurity Act 1993. The South Island of New Zealand is free of the Aujeszky's disease virus and an abattoir survey of culled breeding pigs during 1993 re-confirmed this. A serological survey of feral pigs from throughout the South Island was completed in 1994 with negative results using an ELISA disc method. - 201 - An eradication programme against the disease has been operating in the North Island since December 1989. Herds are screened for Aujeszky's disease by testing all culled breeding pigs at slaughter using an ELISA disc method. In addition, all herds within a 1 km radius of an infected herd are monitored by onfarm serological testing. Infected herds are quarantined and the virus is eliminated from herds either by test and removal, or total depopulation and restocking, or a programme of vaccination using a gl-deleted vaccine followed by test and removal using a complementary gl ELISA. Four infected herds were detected during 1995. The herds were on hobby farms and all were depopulated. This compares with one infected herd in 1994 and no infected herds in 1993 and 1992. The disease is believed to have been eradicated from all commercial herds. A survey of the feral pigs in the North Island is currently being conducted. Based on the results of the complementary gl ELISA, the Aujeszky's disease virus has been eliminated from the eight herds which were vaccinated during the programme. One herd remained under quarantine during 1995. This was a vaccinated herd which was quarantined to ensure that vaccinated pigs were moved only directly to slaughter. All culled breeding pigs in the North Island will continue to be tested at slaughter for at least three years after the last infected herd is removed from quarantine. Echinococcosis-hydatidosis Echinococcus granulosus is notifiable under the Biosecurity Act 1993. A national campaign to eradicate E. granulosus has been operating in New Zealand since 1959 and eradication is anticipated in the near future. All ruminants slaughtered commercially are subject to post-mortem inspection by Ministry of Agriculture meat inspectors. Any lesion which is suggestive of E. granulosus is submitted to one of the Ministry of Agriculture's Animal Health Laboratories for confirmation. When a case of E. granulosus is confirmed, the property from which the infected animal originated is subjected to an investigation. The numbers of animals slaughtered in 1995 were: 26 million lambs, 7.3 million adult sheep, 1.3 million calves and vealers, and 2.5 million adult cattle. Post-mortem inspection of these animals resulted in laboratory submission of 13 suspicious lesions (five from sheep, six from cattle and two from deer). All lesions were in animals from different properties. Hydatids were confirmed in cattle on two properties and in sheep on one property. The only viable cyst was in the sheep. Johne's disease (paratuberculosis) Mycobacterium paratuberculosis is notifiable under the Biosecurity Act 1993. The Ministry of Agriculture maintains a register of properties/herds known to be infected with M. paratuberculosis. As of December 1995, 1,360 sheep flocks were on the Johne's disease register. The sheep population in the South Island is believed to be more heavily and uniformly affected than in the North Island. The total number of cattle herds in which Johne's disease has been notified and confirmed is 2,548. The prevalence is believed to be higher in dairy than in beef herds. The disease has been confirmed in 34 goat flocks and in 70 deer herds. The laboratory tests routinely used are the complement fixation test and agar gel immunodiffusion test. A live Johne's disease vaccine is licensed for use in cattle, sheep and goats. However, in some lines of animals, there has been a problem with the development of granulomas at the vaccination site and in the regional lymph node. In August 1994 discussion was initiated between industry groups and the Ministry of Agriculture with the objective of assessing the present and potential, future economic impacts of the disease. A public discussion document was distributed to livestock industry stakeholders in July 1995. Once analysis of the submissions is completed, recommendations will be made and discussed with livestock industry representatives. -202- Diseases of cattle 4. Bovine tuberculosis Mycobacterium bovis is notifiable under the Biosecurity Act 1993. At 30 June 1995 there were 1,467 (2.45%) cattle herds under quarantine because of tuberculosis. During the preceding 12 months, 903 (61.4%) herds that were under restriction were removed from quarantine and 894 (1.54%) newly identified infected herds were placed under quarantine. A total of 4.04 million cattle were tested during the 12 month season to 30 June 1995, and 5,686 reactors to the caudal fold skin test were identified and slaughtered. Additional 4,944 cattle that were considered to be non-specific reactors to the caudal fold test were given a comparative cervical test (CCT). There were 541 (9.5%) reactors to the CCT and these were slaughtered. In total, 6,227 (0.15%) reactor cattle were slaughtered, with 3,036 (48.8%) showing lesions. A further 1,040 (0.05%) tuberculous cattle were delected during routine meat inspection of the 2.15 million cattle sent for slaughter during the last 12 months. The period prevalence of tuberculosis in cattle (3,036 tuberculous reactors and 1,040 infected cattle found during routine slaughter) for the 1994/95 season (based on 8.3 million cattle) was 0.049%. Cervine tuberculosis (M. bovis) At 30 June 1995, there were 200 (3.4%) herds under quarantine because of tuberculosis. During the preceding 12 months, 112 (54.4%) herds that were under restriction were removed from quarantine and 100 (1.75%) new infected herds were placed under quarantine. During the 12 months to the end of June 1995, 461,530 deer were tested with the mid-cervical intradermal tuberculin test (MCT) and 1,326 reactors were slaughtered. An additional 4,679 deer that were considered to be non-specific MCT reactors were given an ancillary test with either the comparative cervical test (CCT) or the blood tuberculosis test (BTB). There were 130 (2.8%) reactors to the ancillary test and these were slaughtered. In total, 1,456 (0.31%) reactor deer were slaughtered, with 271 (18.6%) showing lesions. A further 300 (0.09%) tuberculous deer were detected during routine meat inspection of the 334,100 deer sent for slaughter during the last 12 months. The period prevalence of tuberculosis in farmed deer (271 tuberculous reactors and 300 infected deer found at slaughter) for the 1994/95 season (based on 1.1 million farmed deer) was 0.052%. Tuberculosis (M. bovis) in feral/wild animals Tuberculous possums and occasionally other feral/wild animals (pigs, deer, cats, ferrets, stoats, hedgehogs and hares) have been identified in association with persistent infection in adjacent cattle and deer herds in 22 discrete areas of New Zealand. Nevertheless possums (Trichosurus vulpécula) are considered the main wildlife vector of tuberculosis for cattle and farmed deer, although in a few areas ferrets are considered an important vector. The Ministry of Agriculture considers that tuberculosis is endemic in six areas where, because of their large size, extensive native bush cover and range of infected species, it is currently technically impossible to eradicate tuberculosis from the feral/wild animal populations. These six discrete areas cover approximately 21.5% of New Zealand's land area, but in the 1994/95 season contained 83.2% and 70.6% respectively of cattle and deer found to be tuberculous and 81.6% and 69.5% respectively of cattle and deer herds under quarantine because of tuberculosis. Tuberculous possums were found associated with the expansion of two endemic areas during 1994/95. Tuberculous possums and ferrets were found to be associated with the expansion of another two endemic areas, and tuberculous feral deer have been implicated in the expansion of one of these areas. The balance of New Zealand is classified as non-endemic. The non-endemic areas contain the remaining 16 areas where tuberculous feral/wild animals have been identified. These are known as Special Tuberculosis Investigation Areas (STIAs). It is considered that tuberculosis can be eradicated from the feral/wild animal populations in the STIAs by the application of current animal control techniques. The STIAs cover approximately 1.5% of New Zealand's land area and in 1994/95 contained 2.8% and 8% respectively of the infected cattle and deer herds. Tuberculosis was identified in possums in one new STIA and confirmed as being eradicated from an existing STIA in 1994/95. -203- The non-endemic areas also include the Fringe areas which encompass the endemic areas. In 1994/95, the Fringe areas accounted for approximately 17% of New Zealand's land area and contained 6 . 1 % and 10.5% respectively of infected cattle and deer herds. The balance of the non-endemic areas are classified as Sur\>eillance. Surveillance areas account for 59% of New Zealand's land area and in 1994/95 contained 9.5% and 12% respectively of infected cattle and deer herds. During 1993/94, the Animal Health Board, which administers the tuberculosis control scheme, implemented a programme aimed at reversing the upward trend in both tuberculin reactor rates and herds under quarantine through a combination of increased movement control restrictions and vector control. Early indications are that these changes, particularly the vector control programme, have been responsible for a reduction in the number of infected cattle and deer herds in 1994/95. For cattle, 1994/95 was the first time since 1980/81 that the number of herds under quarantine for tuberculosis was less than the previous year. Similarly, the number of cattle reactors fell for the first time in 1994/95 relative to any period over the last ten years. This downward trend appears to be continuing in 1995/96. In 1994/95, the Animal Health Board developed a five-year National Pest Management Strategy for controlling bovine tuberculosis in New Zealand. This strategy is required under the Biosecurity Act 1993. Development of the strategy required extensive consultation with stakeholders. The strategy identifies a new herd status system, increased restrictions placed on infected herds and a change to the way vector areas are described and managed. The strategy will be funded through a levy on beneficiaries of the bovine tuberculosis control programme and exacerbators of the problem. The Pest Management Strategy was submitted to the Minister of Agriculture for consideration and it is hoped that it will be implemented in the 1996/97 year. Research programmes have been initiated to provide a better understanding of the tuberculous feral/wild animal problem (particularly possums and ferrets), and a more cost-effective means of controlling them. Ultimately research into a method of biologically controlling the possum population may provide the means of eradicating tuberculosis from them. In addition, a major research effort has been undertaken to develop a vaccine against tuberculosis for cattle, farmed deer and possums. A number of blood tests for tuberculosis in cattle will also be evaluated over the next two years. 5. Enzootic bovine leukosis The enzootic bovine leukosis (EBL) virus is notifiable under the Biosecurity Act 1993. During 1995, a total of 3,885 sera were tested for specific anti-EBL antibodies, with 36 producing a positive reaction. Most of the sera were from animals being tested under export protocols (thus not representative of the cattle population) with only a small percentage of the tests being carried out for diagnostic purposes. Of the seropositive animals, 33 came from known infected herds with the majority, 31, being from a single farm. The test in routine use is the agar gel immunodiffusion test. Several commercial ELISAs were evaluated during the year. Sera made available by the OIE Reference Laboratory in Tubingen, Germany, were used for test evaluation and research into the value of an electrophoretic immunoblot for EBL. A dairy industry funded and managed pilot EBL eradication programme has being proposed and is being undertaken in 1996/97. Diseases of sheep and goats 6. Ovine epididymitis (Brucella ovis) The sheep raising industry operates a voluntary Brucella ovis accreditation scheme, organised jointly by the New Zealand Veterinary Association and the sheep breed societies, with technical advice being provided by the Ministry of Agriculture. A total of 63,725 rams were tested in 1995. The test used in the industry-run B. ovis accreditation scheme is the complement fixation test, with an ELISA and agar gel immunodiffusion test used as additional tests when new infections in accredited flocks are suspected. The routine use of electrophoretic immunoblotting was introduced into the scheme as a confirmatory test, with a focus on the presence or absence of the immunodominant 29 kDa band. -204- Of the 63,725 rams tested. 2.129 (3.34%) were positive and 292 (0.46%) returned a suspicious result. The number of reactors was significantly higher in commercial flocks than in registered ram breeding flocks (6.2% compared to 0.98%) The Central Animal Health laboratory maintains a register of accredited ram flocks. In 1995, 1,401 (86.5%) of 1,619 registered ram breeding flocks and 126 (10%) of 1,259 commercial flocks were accredited free of B. ovis. 7. Caprine arthritis/encephalitis Caprine arthritis-encephalitis (CAE) virus was first isolated from goats in New Zealand in 1981. In 1983, a national survey revealed a seroprevalence of 1.5% in 6,551 goats tested. The prevalence rate was 2.27% in 4,230 daiiy goats and 0.04% in 2,321 angora goats. Clinical manifestations of disease are rarely reported. In 1984 the Ministry of Agriculture, in consultation with the major goat voluntary flock accreditation scheme for the control of CAE. In 1988 there accredited free of CAE and to date over half a million sera have been tested. years the number of samples tested for CAE has decreased as a result of a value of farmed goats, the rarity of clinical disease and the cost of testing. industry groups, launched a were about 1,000 goat flocks However, during the last few reduction in the number and During 1995, 3.749 samples from 111 flocks were tested as part of the accreditation scheme and 3,479 samples were tested for export certification purposes. Thirty-three goats from 14 flocks were seropositive. During 1995, 20 goat flocks were reaccredited, six flocks were newly accredited and nine flocks were subjected to pre-accreditation test. A total of 97 goat flocks were accredited as free from CAE virus infection and 85 of these are on a triennial testing regime. Diseases of horses 8. Equine viral arteritis The equine viral arteritis virus is notifiable under the Biosecurity Act 1993. The virus strain present in New Zealand has low pathogenicity and clinical manifestation of the disease has never been reported. The organism was first made notifiable in 1989 and an equine industry control scheme was subsequently established. This scheme required annual serological testing of all breeding stallions prior to the start of the breeding season. Exceptions were shedder stallions, seropositive non-shedder stallions and vaccinated stallions. To identify stallions shedding the virus in their semen, all seropositive stallions were either testmated to two seronegative mares or virus isolation on semen was attempted. Mares were not required to be tested. Shedder stallions could be used for breeding, but under controlled conditions. Vaccination has been by official permit and only seronegative stallions standing at stud with shedder stallions have been vaccinated. The scheme was reevaluated in May 1992 and as there had been no evidence of viral spread from shedder stallions to non-infected stallions the annual serological testing ceased and only stallions breeding for the first time are now required to be tested. However, seropositive stallions are still required to be semen tested or test-mated to establish if they are shedding the virus. Seroprevalence is highest in standardbred stallions, with only a small number of seropositive thoroughbred stallions (the majority being previously vaccinated horses). There have been no seropositive stallions identified in the other breeds. The number of stallions which are chronic semen shedders continues to decrease, due either to their death or retirement from breeding. Currently only eight shedders arc known. All are standardbreds. -205- Diseases of poultry 9. Infectious bursal disease (Gumboro disease) Infectious bursal disease virus is notifiable under the Biosecurity Act 1993. Infectious bursal disease was first diagnosed in New Zealand in October 1993. The diagnosis was based initially on gross pathology and histopathology of meat chickens and positive serology of suspected flocks. The virus was isolated in December 1993. No clinical signs have been observed in infected chickens and pathogenicity studies on the New Zealand infectious bursal disease virus (IBDV) isolates classified them as mild strains of classical IBDV serotype 1. An epidemiological investigation carried out in 1993 revealed that 80% of the seropositive farms were derived from one hatchery. Only 2 0 % of the seropositive farms were thought to be infected through contact with the infected stock. In 1993. a serological survey revealed 49 infected farms located throughout New Zealand. In 1994. the number of positive farms decreased to 34 and in 1995 only 7 farms (2 meat chicken and 5 egg production) tested positive. All of the farms were located in the North Island in the area believed to be the original point of entry for the virus. The absence of clinical signs, the very slow spread of the virus between in-contact flocks and the ease of the initial propagation of the virus (in embryonated fowl eggs, primary chicken cells, and a mammalian cell line) suggest that the vims is a vaccine strain rather than field strain. It is thought that the virus may have been introduced into New Zealand via a contaminated or mislabelled vaccine. It is anticipated that the current preventive management programme, supported if necessary by the use of killed vaccines (on which assessment projects are being carried out), will restore New Zealand's IBD-free status. Diseases of bees 10. American foulbrood Bacillus lan'ae is notifiable under the Biosecurity Act 1993. American foulbrood (AFB) control programmes have been carried out by apiary inspectors since the passing of the first Apiaries Act in 1905. By the mid-1960s, a strong government inspection programme and the efforts of beekeepers had reduced the reported annual incidence of the disease to less than 0.5% of beehives. However, in the 10 year period 1981-1991, the reported incidence of AFB nearly doubled (from 0.65% to 1.2% of beehives per year). This increase in incidence occurred at the same time as a rapid increase in beehive numbers; 3 9 % increase between 1981 and 1989. In the later part of that same decade, government inspections of beehives for AFB decreased markedly due to budgetary constraints. In 1991, the New Zealand government removed funding for an AFB control programme and the National Beekeepers' Association contracted the delivery branch of the Ministry of Agriculture to provide AFB control services. In the period 1991-1995, the reported incidence of the disease decreased from 1.2% to 0.8% of beehives per year. For the year ending June 30 1995, 2,662 beehives in 1,052 apiaries were either found to be infected with AFB by inspectors, or reported to be infected by beekeepers. During the same period, 7.5% of the apiaries and 4 . 1 % of the hives were inspected as part of the contracted AFB control programme. It is a requirement of the Apiaries Act 1969 that beekeepers inspect their hives for the disease at least once a year and report to the Ministry of Agriculture any changes of apiary location and any AFB found. The National Beekeepers' Association is American foulbrood under the Biosecurity annual incidence of AFB in New Zealand clinical cases of the disease in beehives by currently developing a national pest management strategy for Act 1993. The goal of the strategy is to progressively reduce the over a 10 year period, leading to the eventual elimination of all the year 2006. -206- N I G E R INTRODUCTION Modifications intervenues dans les activités des Ser\>ices vétérinaires Dans le cadre de l'amélioration de la santé animale et des conditions agro-pastorales au Niger, la direction de l'Elevage et des Industries animales (DEIA), à travers le projet PARC-Niger, phase II, s'est vue renforcée de deux nouveaux services : - un service d'appui à la privatisation de la profession vétérinaire ; un service d'appui aux associations d'éleveurs. Les politiques et stratégies dans le secteur de l'élevage sont contenues dans deux textes fondamentaux portant sur : - les principes directeurs d'une politique de développement rural au Niger ; les principes d'orientation du code rural. Les axes principaux de cette politique sont : - la gestion des ressources naturelles ; l'intensification et l'intégration des productions animales à l'agriculture ; la privatisation et la redéfinition du rôle de l'Etat dans le secteur de l'élevage ; les mesures d'accompagnement. A ctivitès des Serxnces vétérinaires Les activités des Services vétérinaires sont orientées vers : - la prophylaxie des maladies animales, à travers des campagnes de vaccination contre les épizooties majeures du cheptel, la surveillance et l'épidémio-surveillance des maladies ; le contrôle des mouvements du cheptel à l'intérieur et à l'extérieur du pays ; l'inspection des denrées alimentaires d'origine animale ; la privatisation de la profession vétérinaire par la mise en place des structures vétérinaires privées pouvant mener des activités variées (mandats sanitaires, vente de médicaments et autres intrants de l'élevage) ; le renforcement de l'efficacité des associations d'éleveurs et leur responsabilisation dans la gestion des points d'eau pastoraux et des aires de pâturage.

Mesures de lutte : mise en interdit des troupeaux atteints, limitation des mouvements d'animaux, isolement des malades, traitement spécifique des aphtes et antibiothérapie. 2. Péripneumonie contagieuse bovine En 1995. la péripneumonie contagieuse bovine s'est limitée aux régions de Dosso, Maradi et Tahoua. Mesures de prophylaxie : vaccination au moyen du vaccin bivalent "Bivac" (peste bovine / péripneumonie contagieuse bovine) ou du vaccin monovalent "Périvac". Mesures de lutte : mise en interdit des troupeaux atteints et isolement des malades ; prélèvements de sang, de liquide pleural et de fragments de poumon hépatisé et analyse en laboratoire ; délimitation de zones infectées et contaminées, mise en interdit desdites zones ; abattage sanitaire total après confirmation du foyer par le laboratoire ; vaccination en anneau autour du foyer. 4. Clavelée et variole caprine Mesures de lutte : isolement des animaux atteints, séquestration des troupeaux et vaccination autour des foyers. 5. Maladie de Newcastle Mesures de prophylaxie : vaccination. II. MALADIES DE LA LISTE B Les maladies de la Liste B, notamment les maladies communément appelées "pseudo-telluriques", occupent toujours la première place parmi les pathologies enregistrées en 1995. Parmi elles, les pasteurelloses bovines, ovines et caprines, ainsi que la fièvre charbonneuse (charbon bactéridien) et le charbon symptomatique ont causé des pertes aux élevages traditionnels. Certaines maladies parasitaires (douves, echinococcoses, cysticercoses) font l'objet de plusieurs saisies partielles d'organes dans les abattoirs, mais leur répartition et leur fréquence sont mal connues. D'autres maladies telles que les tuberculoses sont également constatées à l'abattoir. 1. Fièvre charbonneuse Mesures de prophylaxie : vaccination au moyen du vaccin spécifique "Carbovac". Mesures de lutte : isolement des malades ; prélèvements de sang ou d'organes et analyses en laboratoire ; vaccination des troupeaux exposés à la maladie. -208- Evoluíion de la situation de la fièvre charbonneuse Espèce 2. entre 1994 et 1995 Année 1994 Année 1995 Foyers Cas Morts Foyers Cas Morts bov 14 72 24 17 453 48 ovi 17 150 148 33 455 229 Rage Mesures de lutte : mise en observation des chiens mordeurs pendant une à deux semaines ; abattage sanitaire ; prélèvement d'organes (têtes) et diagnostic en laboratoire ; vaccination ou abattage des chiens errants.

Aujeszky's disease (pigs), transmissible gastroenteritis (pigs) and Newcastle disease (poultry) for documentation purposes continued through 1995. No positive reactors were found. A national programme for the surveillance and control of salmonella in live animals and animal products was established early 1995 (see III, 2). I. LIST A DISEASES Diseases never reported Bluetongue African horse sickness African swine fever Highly pathogenic avian influenza Newcastle disease Vesicular stomatitis Swine vesicular disease Rinderpest Peste des petits ruminants Lumpy skin disease Rift Vallev fever Diseases reported absent in 1995 (in parentheses: Foot and mouth disease (1952) Contagious bovine pleuropneumonia (1860) date of last outbreak) Sheep pox and goat pox (1882) Classical swine fever (1963) II. LIST B DISEASES Diseases of multiple 1. species Anthrax Anthrax has a low sporadic occurrence in Norway. The last reports of this disease were single cases in 1983, 1990 and 1993. 2. Rabies Rabies has never been diagnosed in mainland Norway. The disease has sporadically been diagnosed in fox, reindeer and seal in the archipelago of Svalbard in 1980, 1981, 1987, 1990 and 1992. No new cases were diagnosed in 1995. 3. Paratuberculosis Paratuberculosis occurs only in goats in Norway, due to an apparently goat-pathogenic strain of Mycobacterium paratuberculosis. Paratuberculosis in goats is confined to certain regions in the western part of Norway. Vaccination of all goat-kids less than four-week old is compulsory in affected regions. By 31 December 1995, 75 goat herds were under official restrictions for this infection. -210- Diseases of cattle 4. Bovine tuberculosis Bovine tuberculosis was last recorded in a single herd in 1986. Diseases of sheep and goats 5. Scrapie In 1995, scrapie was diagnosed in sheep in eight different herds. All affected herds were located in the same area of the south-western part of Norway as previous cases, i.e. the counties of Rogaland and Hordaland. All the animals (approximately 1,170 sheep and 35 goats) were destroyed. There are strict regulations on the movement of small ruminants across county borders and movement out of the affected region has not been permitted for years. Further restrictions on contact between herds (i.e. breeding and trade) in this region were enforced in 1995. Since 1981, scrapie has been diagnosed in altogether 16 herds in the counties Sogn and Fjordane, Hordaland and Rogaland in western Norway. No cases have been detected in the county of Sogn and Fjordane since 1985. A total of approximately 2,400 sheep and 200 goats were destroyed. III. OTHER DISEASES 1. Mucosal disease / bovine virus diarrhoea The national control programme which started in 1992 continued through 1995. The number of infected herds (dairy and beef cattle) with a high probability of being infected was 2,076 (prevalence ± 8%) by the end of 1995, this being approximately 700 herds less that one year before. The result is based on serological examinations of herd milk samples followed by individual milk and blood samples from heifers. 2. Salmonella infections A nationwide surveillance and control programme for salmonella in live animals and animal products was launched in 1995. The aim of the programme is to provide reliable documentation for the salmonella status in live animals and animal products in Norway, and to prevent an increased occurrence of salmonella infections. The number of samples included is large enough to demonstrate a prevalence of salmonella infection of 0 . 1 % of the individuals. Measures to be taken when salmonella infection is detected are detailed in new regulations issued by the Ministry of Agriculture. The surveillance includes fecal sampling of poultry units (breeding units, layers and broilers) and herds of pigs kept for breeding purposes. The rest of the pig industry and the cattle industry are surveilled by randomized sampling of intestinal lymph nodes at slaughter. Additionally, the salmonella situation is monitored in abattoirs and plants for cutting of fresh meat. In 1995, approximately 11,500 samples used for the surveillance of live animals were examined. The results suggest that the prevalence of salmonella is less than 0.2% in the population of pigs and cattle. 3. Infectious salmon anaemia Two new outbreaks of infectious salmon anaemia were reported in 1995 in the county of Sogn and Fjordane. The number of new outbreaks has been markedly reduced over the last years. Four farms were still under restrictions by 31 December 1995. -211 - N O U V E L L E - C A L É D O N I E I. MALADIES DE LA LISTE A Aucune maladie de la Liste A n'est apparue en 1995 et n'a jamais été diagnostiquée en Nouvelle-Calédonie. La surveillance de ces pathologies est assurée sur le terrain par les praticiens au sein des abattoirs et par l'inspection vétérinaire. Un suivi épidémiologique permanent sur des élevages sentinelles qui, à travers les échanges qu'ils pratiquent présentent le profil de risque le plus intéressant, est conduit notamment vis-à-vis de la peste porcine et des pestes aviaires. II. MALADIES DE LA LISTE B Maladies communes 1. à plusieurs espèces Leptospirose La leptospirose reste la maladie principale en Nouvelle-Calédonie. Le nombre de cas est corrélé avec les fortes précipitations enregistrées en mars, avril et août. Icterohaemorrhagiae est le sérogroupe qui prévaut chez les chevaux, tandis que chez les bovins Sejroe hardjo est le serovar dominant. Maladies des porcins Le Territoire est indemne de maladie d'Aujeszky, gastro-entérite transmissible et syndrome dysgénésique et respiratoire du porc, maladies qui font l'objet d'un suivi épidémiologique. La pathologie respiratoire observée dans certains élevages est à rattacher à des infections mycoplasmiques responsables de pneumonie enzootique (Mycoplasma hyopneumoniae), avec une prévalence de 12 %. 2. Trichinellose L'enquête porcine conduite sur les élevages a permis de mettre en évidence des sérologies positives à l'épreuve ELISA vis-à-vis de la trichinellose, avec une prévalence de 69 %. A ce jour, aucune découverte d'abattoir n'a mis en évidence la présence de ce parasite. Les digestions pepsiques entreprises sur des tissus de porc de réforme n'ont pas permis de mettre en évidence des larves de trichines, ce qui semble contradictoire avec les résultats de la méthode sérologique. Les recherches se poursuivent néanmoins. Maladies des volailles Le suivi permanent des élevages de poules pondeuses concerne, outre les pestes aviaires, la maladie de Gumboro, la bronchite infectieuse, l'encéphalomyélite aviaire et les salmonelles. Pour les trois premières pathologies, identifiées en Nouvelle-Calédonie, le suivi permet de contrôler la prise vaccinale, notamment pour la maladie de Gumboro. Pour ce qui concerne les salmonelles, une attention particulière est portée vis-à-vis de Salmonella pullorum gallinarum et de S. enteritidis. La première espèce n'ayant pas été identifiée, son absence du Territoire peut être confirmée. La découverte de la seconde a fait l'objet de mesures particulières au niveau des couvoirs et des élevages de poules pondeuses. -212- Maladics des crevettes pénéïdes (Penaeus stylirostrisj Les investigations sur les baisses de production associées à des taux de mortalité anormaux qui ont touché les élevages de crevettes se sont poursuivies en 1995. Les crevettes moribondes présentent une septicémie bactérienne. Le ribotypage des vibrions isolés a permis de révéler deux groupes, dont l'un, auquel appartient Vibrio penœicida, au fort pouvoir pathogène. Les nombreux corps basophiles associés, retrouvés dans des tissus, font penser à des images trouvées dans des infections virales de type yellow head ou Taura syndrome. Les symptômes pathologiques ont pu être reproduits après ultrafiltration de broyât d'organe et inoculation parentérale. Si aucun résultat ne permet de conclure sur l'étiologie de cette pathologie observée (virale, microbienne, toxinique), il n'en demeure pas moins que celle-ci est sous l'influence de l'environnement (température, salubrité...) comme le montrent les pics saisonniers de mortalité. -213- O M A N I.

III. OTHER DISEASES 1. Tetanus A total of 70 goats and 3 cattle were reported to have contracted tetanus. 2. Blackleg No case was reported in 1995. However, the vaccination programme was continued and a total of 154,252 vaccinations in cattle were administered. 3. Botulism A total of 657 cattle (499 deaths), 6 camels (4 deaths) and 12 goats (10 deaths) were reported, mainly in Dhofar. A few cases in cattle were also reported in Batina (Suweiq, Rustaq, Sohar and Seeb). The disease -215- is controlled by vaccination using types C and D toxoid and a total of 156,417 doses were administered in cattle. 4. Actinomycosis A total of 5 goats (in Seeb, Sohar and Nizwa) and 1 bovine (in Barka) were reported sick. 5. Contagious pustular dermatitis Reported cases included 2,595 goats, 29 sheep and 74 camels. 6. Actinobacillosis One bovine (in Seeb) and two goats (in Nizwa and Sohar) were found to be positive.

Environ 8 000 spécialistes vétérinaires travaillent dans ces services. Parmi eux, 2 % sont employés dans le secteur administratif et le reste travaille dans le secteur productif. L'administration des Services vétérinaires est l'agriculture. Dans 12 régions et dans la ville réorganisés en Directions vétérinaires auprès de de lutte contre les maladies des animaux sont (khokimiyat) de district. assurée par la Direction vétérinaire d'Etat du ministère de de Tachkent, les services vétérinaires et l'inspection ont été l'administration (khokimiyat) de région. De même, les centres devenus des services vétérinaires auprès de l'administration Suite à la privatisation des biens de l'Etat et à la création d'exploitations privées sous forme de sociétés anonymes, les organismes vétérinaires du pays renforcent le réseau des services vétérinaires privés. Ainsi, à l'heure actuelle, 1 322 consultations vétérinaires privées ont été ouvertes. La prophylaxie des maladies infectieuses en Ouzbékistan se base surtout sur la vaccination. Or un seul laboratoire produit dans le pays les vaccins nécessaires, et ni leur quantité ni leur assortiment ne peuvent répondre à la demande. En outre, le pays manque de devises convertibles pour importer du vaccin. I.

Le diagnostic, clinique et anatomo-pathologique, a été confirmé en laboratoire. Le taux de contamination du cheptel de cette exploitation était de 10 %. 04-92 -219- II. MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Fièvre charbonneuse La fièvre charbonneuse a été signalée chez les bovins dans la région d'Andijan (2 foyers, 6 cas), dans la région de Namangane (3 foyers, 3 cas), dans la région de Boukhara (1 cas) et dans la région de Sourkhandarya (1 cas). Concernant les ovins, les chiffres sont les suivants : 1 cas dans la région de Samarkand et 1 cas dans la région de Sourkhandarya. Le diagnostic a été confirmé en laboratoire par analyse bactériologique, microscopie et expériences sur des animaux. 2. Rage Par rapport à l'année 1994, le nombre de foyers et d'animaux contaminés a diminué de 165 foyers et 260 cas, bien que la contamination ait augmenté dans certaines régions (Djizak, Samarkand et Khoresme). La source principale de l'infection reste la faune sauvage et les chiens, qui représentent 73 % des cas. Maladies des bovins 3. Tuberculose bovine Le nombre de foyers de tuberculose bovine a considérablement augmenté en 1995, surtout dans les régions de Djizak et Samarkand : 18 foyers ont été enregistrés dans la région de Djizak, et 42 foyers dans celle de Samarkand. En ce qui concerne la région de Djizak : dans 61,1 % des exploitations infectées moins de 5 % des bovins examinés étaient infectés et dans 16,6 % des exploitations le taux d'infection était de 5 % à 10 %. En ce qui concerne la région de Samarkand : dans 38 % des exploitations infectées les animaux infectés représentaient moins de 5 %, et dans 26 % des exploitations de 5 % à 10 % des animaux étaient infectés. III. AUTRES MALADIES Maladies communes à plusieurs espèces Le nombre de cas de charbon symptomatique des bovins et de salmonellose bovine, ovine et porcine a augmenté en 1995. La diagnostic de ces maladies a été assuré par des recherches bactériologiques. -220- P A K I S T A N INTRODUCTION The veterinary health activities in the country are being strengthened under a livestock development project. The main features of the project activities are as follows: Creation of Planning Cells A planning cell has been created in each provincial livestock headquarters. The main objective of the cell is to serve as a source of information for making policies on livestock so that it can be developed to meet our future needs. Livestock Extension Training Centre A training centre has been set up to provide technically skilled manpower for the livestock sector. Training courses and refresher courses are offered for private / in-service technical staff to update their professional knowledge. Extension activities More than 50 Intensive Livestock Production Areas (ILPA) and Livestock Production Extension Nuclei (LPEN) have been set up in project areas throughout the country. In these areas, breed improvement programmes, lamb fattening programmes, field training and other livestock health activities are under way. The objective is to turn these areas into model livestock production centres, to be replicated elsewhere in the country later on. Rehabilitation / relocation of slaughterhouses Under veterinary public health services, the renovation, rehabilitation or relocation of selected slaughterhouses has been planned. The idea is to develop demonstration slaughterhouses of international standard for replication by the private sector. Disease surveillance system A disease reporting, monitoring and analysing database system is in operation on a trial basis in selected project areas. This system would ultimately develop into a full, national scale, disease surveillance system on livestock health, and would thus help in making strategic policies on the control or eradication of fatal livestock diseases. Privatisation of Veterinary Ser\>ices A gradual privatisation of Veterinary Services is also planned. This will be implemented in phases in a costeffective manner. Meanwhile, provinces are seeking advice from different livestock experts about its impact on prices for livestock products and the Government is encouraging the private livestock sector to play its role in livestock production and health activities. Many more projects are under consideration at the government level to develop the livestock sector for export purposes. -221 - I.

No serious outbreaks were reported, although approximately 3,000 cases were recorded country-wide in 1995. The serotypes isolated included O, A, C and Asia 1, virus type A being the most prevalent. In a few clinically suspected cases no virus was detected. The economic losses, in terms of increased working hours, and reduced milk and meat production, remained significant. Animal immunisation and zoosanitary measures were the key controling the disease in affected areas. The affected animals were symptomatically treated. 2. Rinderpest Sporadic cases were reported in border areas in the North-West Frontier region. The focal point of the disease was believed to be in a neighbouring country, from which it spread into Pakistan through illegal movements of animals across the border. It is estimated that about 247 animals died due to the disease, but its incidence remained low due to vaccination. 3. 12-94 12-94 12-94 -K. Foot and mouth disease - Virus SAT 1 Foot and mouth disease - Virus SAT 2 Foot and mouth disease - Virus SAT 3 Swine vesicular disease Peste des petits ruminants 1. 1995 Jun Jul Feb Highly pathogenic avian influenza (fowl plague) This disease hit the commercial poultry sector for the first time. Rawalpindi and Islamabad were the most severely affected areas. Chicken breeder flocks, aged 7 to 65 weeks, were mostly affected. Mortality was nearly 200,000 birds. The direct losses were estimated to be 19.44 million PKR, while indirect losses, in terms of day-old chicks and poultry eggs and meat amounted to 841.68 million PKR. The disease was initially suspected to be a velogenic form of Newcastle disease. Clinical and serological examinations of specimens revealed that it was fowl plague, which was later confirmed by foreign laboratories. H7 type virus was found to be the main culprit. 12-93 1992 12-94 -222- The following remedial measures were adopted for its control: 4. - Clause 144 was imposed on the movement / transportation of birds from the affected areas. - The flocks in the area were incinerated under the supervision of officials from the Government Livestock Department. - An indigenous vaccine was prepared and made part of the vaccination schedule of the commercial poultry forms. The disease is now under control. Newcastle disease The occurrence of disease was low sporadic. Mortality in 1995 was estimated to be more than 200,000 birds, involving all poultry categories. The infection was often found in combination with infectious bursal disease. The affected birds showed typical signs of petechial haemorrhage in the proventriculus, intestines and caecal glands. Misshapen eggs were observed in affected laying stock. The farmers were well aware of the disease and therefore regularly vaccinated their flocks as part of the vaccination schedule The layer farmers monitored their flocks for haemagglutination inhibition titres from private/government laboratories. The vaccination schedule adopted in the country for Newcastle disease virus is proving effective to control the disease. II. LIST B DISEASES Diseases of cattle 1. Haemorrhagic septicaemia The disease was observed in both skin and pulmonary forms. The skin form was dominant. High incidence was recorded in flood-affected areas; elsewhere the prevalence of the disease was low sporadic. A mass campaign was launched for vaccination against the disease by provincial livestock departments. Special camps were set up for vaccination in the flood-affected areas. The death toll in these areas was 2.000 animals of different age groups. A total of 1,300 cases were reported in the rest of the country. 2. Trypanosomiasis The disease occurred in the country throughout the year with low frequency. Dirty resting places and pond water along with marshy areas nearby were the main predisposing factors. Regular spraying of the premises and deworming of the animals helped considerably control of the disease. Diseases of poultry 3. Infectious bursal disease (Gumboro disease) Infectious bursal disease (IBD) remained a major problem for the poultry sector throughout the year, with varying intensity. Three shots of IBD vaccine per broiler/layer crop was generally practiced. The outbreaks were often reported in vaccinated flocks, indicating either a faulty vaccination procedure or the prevalence of different field strains. Mortality in the affected flocks remained around 18-20%. The existing vaccination schedule showed partial success in the control of the disease in certain areas. The current situation is expected to continue until an indigenous vaccine can be prepared from the local field strain. Mortality from the disease was nearly 150,000 chickens. 4. Chronic respiratory disease (Mycoplasmosis (M. gallisepticum)) Chronic respiratory disease (CRD) was mostly observed in the winter season. CRD was often precipitated by farmers adopting a careless approach to treatment of infectious coryza. Economic losses in terms of mortality were low. Medication of the flocks for a longer period induced a partial recovery. Relapses of the disease in treated flocks were also observed. -223- Remedial measures included the following: - 5. isolation / treatment of affected flocks; emphasis on treatment of infectious coryza in flocks; variations in temperature between the shed and the surroundings are kept to a minimum to avoid environmental stress. Pullorum disease (Salmonella pullorum) Pullorum disease was observed throughout the year. One- to 14-day-old chicks were mostly affected. Poor management and chicks from diseased breeder flocks were the main factors in disease occurrence. Early chick mortality with unabsorbed yolk was the main clinical finding. A pullorum test was used for confirmation. Early medication and improved management practices helped in the control of the disease. III. OTHER DISEASES 1. Helminthiases Dirty resting places and the drinking of dirty pond water, along with the proximity of marshy areas were the main predisposing factors for the disease. The sharing of common grazing pastures were the source of spread. The disease was never considered due to the low mortality rate, although its economic impact, in terms of weight loss, production loss and the vulnerability of affected animals to other diseases was tremendous. The control measures adopted to check this latent infection, included education of farmers regarding the regular spraying of premises and deworming/dipping of animals with some effective broad spectrum anthelmintic proved to be helpful. A supply of clean drinking water was also suggested. 2. Hypocalcaemia Individual cases were recorded in parturated animals. The cause was found to be an unbalanced diet fed to pregnant animals, especially during the last trimester. 3. Mastitis This is a common problem in lactating animals. The causes were mechanical as well as bacterial. The bacteria isolated included Escherichia coli, Streptococcus sp. and Corynebacterium sp. -224- P A R A G U A Y ENFERMEDADES DE LA LISTA A Panorama general Enfermedades señaladas en 1995 Lengua azul Peste porcina clásica Enfermedad de Newcastle Enfermedades nunca Total 1995 +? +? 2 3 1 4 Ene Feb 0 0 0 0 Mar 0 2 Abr May 1995 Jun Jul 0 0 0 0 0 0 1 0 F.P.

Diversos factores influyeron para este logro, entre los que se pueden citar: - Un aumento gradual y sostenido del número de bovinos vacunados y la revacunación de bovinos menores de 24 meses para su movilización cualquiera sea su destino. Esta medida impide la movilización de animales primo vacunados y reduce sensiblemente el riesgo de ocurrencia de la enfermedad. - El fortalecimiento de la vigilancia con la participación del productor pecuario, el permanente del personal de campo y el mejoramiento de los sistemas de comunicación. - El Sistema Nacional de Alerta de Ocurrencia de Fiebre Aftosa, con la notificación rápida de sospecha que se incluye en el Sistema De Vigilancia Epidemiológica a nivel nacional y en el Convenio de la Cuenca del Plata. - Las notificaciones de sospecha que son atendidas y registradas en su totalidad. En los casos en que las pruebas laboratoriales arrojan resultados negativos a fiebre aftosa, se llevan a cabo pruebas diagnósticas diferenciales a fin de especificar la patología. - La integración plena de los productores pecuarios al Programa de erradicación de la Fiebre Aftosa conformando las Comisiones de Salud Animal, todas reconocidas por Resoluciones del SENACSA. - Desde el inicio del Programa de Erradicación se viene efectuando la atención emergencial de los focos de fiebre aftosa, atendidos con prioridad absoluta, con seguimiento veterinario profesional a nivel de campo y apoyo desde el nivel central. Normalmente, las medidas técnico-sanitarias adoptadas para estos casos son: cuarentena del área, prohibición de concentración y movilización de animales en el área de influencia del foco, interdicción de propiedades afectadas, interdicción de caminos y vacunación perifocal en forma oficial, adiestramiento 12-94 11-94 -225- - La aplicación de Planes Estratégicos de Vacunación en áreas consideradas endémicas primarias ha elevado considerablemente la cobertura de la vacunación en las mismas desde un 3 2 % a un 68%. Estas áreas son puramente extractivas. Estos avances en la erradicación de la fiebre aftosa son también reflejo del mejoramiento de la situación sanitaria de esta enfermedad observada en todo el área que abarca el Proyecto de Erradicación de la Cuenca del Plata. Ley de erradicación de la fiebre aftosa El Programa Nacional de Erradicación de la Fiebre Aftosa, para lograr y afianzar sus objetivos, necesita de la aplicación de medidas sanitarias más estrictas que cuenten con un respaldo técnico legal. En ese sentido, se encuentra en el senado de la Nación un Proyecto de Ley de Erradicación de la Fiebre Aftosa que ya recibió sanción favorable de las Cámaras de Diputados y Senadores y espera su promulgación muy pronto. El Proyecto incluye aspectos técnicos muy importantes tales como la figura de predios de riesgo, tratamiento para animales sueltos en la vía pública, tropas en arreo, faena anticipada o sacrificio sanitario de animales, dependiendo de la caracterización epidemiológica de las áreas de donde provengan y de acuerdo a que estén declaradas libres o no, con indemnización de fondos provenientes de varias fuentes previstas actualmente en esta Ley. Están previstas, asimismo, fuertes multas y sanciones por el incumplimiento de las medidas sanitarias y administrativas exigidas en relación a la erradicación de la fiebre aftosa, actualmente en marcha. -226- P E R Ú INTRODUCCIÓN La prioridad del Servicio Nacional de Sanidad Agraria es erradicar la fiebre añosa del país, dentro del mediano plazo. En un segundo orden se encuentran otras enfermedades de la Lista A. La pacificación lograda en el país así como las condiciones económicas más estables, nos permiten restituir progresivamente los servicios oficiales en reas de donde se los tuvo que suspender. Es política del sector, promover la participación privada, en las acciones de sanidad animal. I.

Portugal maintains a 100,000-dose vaccine bank of virus types A, O, C. 2. Swine vesicular disease This disease occurred for the first time in Portugal in August 1995. It was diagnosed through random sampling of imported animals. The animals did not show any clinical signs, although the virus was isolated from stools of seropositive animals. All the animals in the outbreak were slaughtered and destroyed. 3. Contagious bovine pleuropneumonia In 1995, around 1,100,000 animals were submitted to serological testing, of which 0 . 1 1 % were positive. Only two Regional Directorates in the north of the country registered outbreaks, with a total of 11 outbreaks, compared to 63 in 1994. 4. African swine fever A surveillance programme for this disease is still in force, maintaining Portugal's status of freedom. 5. Newcastle disease Only two outbreaks of Newcastle disease were reported in 1995, both of which occurred in the same municipality. Vaccination of all poultry is being carried out and trading of poultry is restricted in infected areas. 0000 12-94 10-94 -231 - II.

En 1993, une vaccination sélective a été instaurée contre la peste bovine et vise au bout de quatre ans l'arrêt des opérations prophylactiques afin de s'inscrire dans le processus de déclaration de pays indemne de la maladie. La vaccination contre la péripneumonie contagieuse bovine sera poursuivie aussi longtemps que la menace persistera et que les conditions de son eradication ne seront pas réunies. Les objectifs de vaccination contre la peste bovine et la péripneumonie contagieuse bovine pour la campagne 1995 sont respectivement de 941 500 et 1 404 100 têtes de bétail. Les taux respectifs de réalisation sont de 87 % et 86 %. 2. Peste des petits ruminants La vaccination contre cette affection est obligatoire depuis octobre 1995. 3. Fièvre de la Vallée du Rift La sérosurveillance de la fièvre de la Vallée du Rift mise en place depuis 1987 (année de la première épizootie) avec le suivi des troupeaux sentinelles se poursuit dans la vallée du fleuve Sénégal et dans le Ferio. De 1988 à 1993, aucun cas clinique n'a été observé au niveau des troupeaux d'animaux sentinelles. La prevalence des anticorps neutralisant le virus de la fièvre de la Vallée du Rift a régulièrement décru de 1988 (24,4 %) à 1993 (1 % ) . En 1994, deux foyers de fièvre de la Vallée du Rift ont été identifiés chez les petits ruminants dans des sites localisés dans la zone du fleuve Sénégal. Dans la vallée du Ferio, une transmission active du virus a permis l'identification des vecteurs en période inter-épizootique : isolement de dix souches chez Aedes vexans et trois chez Aedes ochraceus. Cette circulation a été confirmée par trois seroconversions et un isolement dans un troupeau d'ovins. En 1994, l'amplification en période humide n'a pas atteint le seuil pouvant déclencher une épizootie comparable à celle de 1987. La situation en 1995 est la même que celle de 1994. 12-94 12-94 08-94 12-94 -233- 4. Peste équine Les opérations de prophylaxie médicale ont été conduites avec un vaccin fabriqué par le laboratoire national. Afin de mieux contrôler cette affection, la vaccination sera rendue obligatoire en 1996. 5. Maladie de Newcastle Un seul foyer a été déclaré, mais cette maladie est très répandue en milieu rural. Plus de 9 millions de doses de vaccin ont été utilisées en 1995 pour la vaccination contre la maladie de Newcastle dans les élevages modernes et dans les élevages traditionnels. Une opération de vaccination de masse a été initiée par la Direction de l'élevage à partir du mois d'octobre 1995, afin de contrôler cette maladie en milieu rural. II. MALADIES DE LA LISTE B 1. Charbon bactéridien (fièvre charbonneuse) Les maladies telluriques (fièvre charbonneuse, charbon symptomatique et botulisme) sont maîtrisées. Elles sont signalées épisodiquement dans les régions méridionales (Kolda et Ziguinchor) et septentrionales (Louga et Saint-Louis).

Septicémie hémorragique La pasteurellose bovine (septicémie hémorragique) constitue une préoccupation majeure. III. AUTRES MALADIES La recrudescence des maladies parasitaires telles que les trématodoses notée en 1993 (fasciolose et schistosomoses) dans la zone du Delta du fleuve Sénégal, notamment autour du lac de Guiers où une importante mortalité de bovins a été rapportée, reste d'actualité. Ces affections sont signalées dans la partie de la zone sylvopastorale concernée par la remise en eau des vallées fossiles. Actuellement, la prévalence de la fasciolose progresse parallèlement à la prolifération des mollusques vecteurs (Lymnea natalensis, Bulinus sp.) devenus abondants dans la zone du Delta et du lac de Guiers suite à la mise en service des barrages de Diama et de Manantali ainsi que dans la vallée du Ferio revitalisée. -234- S I I M G A P O R E INTRODUCTION The Primary Production Department, which is responsible for veterinary services in the country, was re-structured in April 1995. The new organisation comprises the Animal and Plant Health Inspection Division (APHID), the Veterinary Public Health / Food Supply Division, the Agrotechnology Division and the Corporate Services Division. APHID is an extension of the previous Veterinary' Division, which was responsible for animal health only. The new division has additional responsibilities for plant health as well as animal welfare and control. I.

LIST B DISEASES 1. Duck virus hepatitis One case of duck virus hepatitis was reported in a flock of 15-day-old ducklings hatched from imported eggs. This was the first case of the disease since 1991. 2. Duck virus enteritis Duck virus enteritis was detected for the first time in the country in December 1995. The disease affected two farms, close to each other, at about the same time. Peking and mule ducks reared for meat were affected. However, layer ducks in one of the affected farms were apparently resistant. Serological testing showed that the latter had antibodies to duck virus enteritis. All ducks in both farms were imported stock. Morbidity and mortality were high. All affected flocks were destroyed and thorough disinfection of the farms carried out. Almost all ducks in the country are imported. A surveillance plan has been implemented to detect duck virus enteritis in imported ducks. Vaccination would be introduced if necessary. 3. Marck's disease Marck's disease was diagnosed in two vaccinated pullet flocks. Morbidity was very low, about 1%, in both outbreaks. 4. Pullorum disease (Salmonella pullorum) Salmonella pullorum was isolated on three occasions. One was from positive reactors to the rapid whole blood slide agglutination test, and the others from hatchery samples. Routine monitoring for S. pullorum is carried out under the voluntary Pullorum Disease Eradication Scheme. -235- S L O V A K I A INTRODUCTION The activities carried out by Veterinary Sendees in 1995 included the following: - Preparation of a new Act on veterinary care (at present, the Act No. 215/1992 and the Act No. 11/1992 are in force) along the lines adopted by the European Union (EU). - Act No. 115/1995 of National Council of the Slovak Republic on the protection of animals and additional decrees are being formulated. - Preparation for negotiations concerning intergovernmental agreements in the field of veterinary and phytosanitary protection of State territory between EU States and the Slovak Republic. - Working out the proposal for signing intergovernmental agreements in the field of veterinary medicine with Slovenia (agreement already signed), and the Czech Republic, Israel and Romania (agreements are in preparation). - Development of legislative and veterinary directives similar to those in force in the EU (i.e. the "white book"). - Harmonisation of veterinary requirements concerning the import of live animals and of foodstuffs and raw materials of animal origin. - Participation in meetings of countries of Central Europe in connection with eradication of rabies in foxes, - Organization of an international conference on diseases in bees and brood in cooperation with the FAO (Nitra, September 1995). - Staffing and material provision (computers, fax) in border veterinary points. - Technical equipment provision for the elimination of animals by stamping out in connection with the occurrence of classical swine fever. Solution to the ecological problems related to the occurrence of classical swine fever, ascaridosis and echinococcosis (E. multilocularis); - Solution to the problem of early diagnosis and antigenic differentiation of classical swine fever virus strains isolated in the Slovak Republic. This problem was solved by the national reference laboratory for classical swine fever (State Veterinary Institute, Zvolen): 1. comparison of various laboratory methods for the detection of classical swine fever vims in blood; 2. antigen differentiation of classical swine fever isolates from epizootic during the period 1993-1995. - Establishment of reference laboratories for classical swine fever, viral diseases in poultry, mycobacteriosis. serotyping and phagotyping of salmonellae, anaerobic microorganisms; - Development of an eradication plan for Aujeszky's disease and infectious bovine rhinotracheitis; - Creation of a sub-commission for zoonoses at the the Slovak Republic Central Commission for the control of infectious diseases. Its activities include the development of sun'eillance of zoonosis in cooperation with the public health authorities. The following complete materials were prepared and issued in the year 1995: 1. surveillance of zoonoses: helminthozoonoses; 2. surveillance of zoonoses: leptospirosis, tularaemia, arbovims infections, tick-borne encephalitis, small terrestrial mammal reservoirs; 3. surveillance of zoonoses: tuberculosis and other mycobacterioses. -236- I.

Foot and mouth disease antibodies were detected in 164 animals (i.e. 1.1%). The serotypes were represented as follows: O A C 75.0% 43.3% 40.2% All examined porcine serum samples (467) and sheep serum samples (577) were negative for foot and mouth disease antibodies. 2. Classical swine fever (hog cholera) Vaccination against hog cholera ceased on the whole territory of the Slovak Republic on 1 October 1993. However, in 1995 emergency vaccination was permitted, in order to minimize the direct economic losses. A total of 450,916 doses of hog cholera vaccine were used. In 1995, there were 16 outbreaks of hog cholera in 8 districts. The outbreaks were eradicated by the stamping out method. A total of 8,659 pigs died or were destroyed. Emergency vaccination was carried out in protection zones and surveillance zones. The natural source of infection was the wild boar population, which, in the affected districts, suffered considerable losses due to the disease. Hog cholera in wild boars was controlled: - by active screening throughout the territory of the Slovak Republic with appropriate measures being applied in areas where the disease was detected; - by examination of the all wild boar shot within the surveillance zone and, in regions without occurrence of hog cholera, screening by laboratory examination of 2 0 % of all wild boar that are shot; - by the systematic collection of dead wild boar, their laboratory examination followed by the application of any necessary sanitation; - by a reduction in the wild boar population. 11-94 -237- In order to monitor the occurence of hog cholera in the wild boar population 1,139 wild boar from 765 different locations were sampled and laboratory tested. Of these, 24 animals (i.e. 2.1 %) were found to be positive. II. LIST B DISEASES Diseases of multiple 1. species Anthrax Anthrax was recorded only in cattle. Vaccination was used only in "stationary places of occurrence". A total of 6,343 animals were vaccinated. 2. Aujeszky's disease The national eradication programme was worked out and has been realized. Breeding pigs are vaccinated with the inactivated gl vaccine in some districts. Other animal species were not vaccinated. 3. Echinococcosis-hydatidosis Echinococcosis-hydatidosis was recorded only in pigs. 4. Leptospirosis Serologically positive reactors were recorded in 10 outbreaks. Of these 4 were in cattle and 6 in pigs. Sporadic abortions were reported in pigs. Diagnosis was confirmed by the presence of antibodies against the following serotypes: Leptospira sejroe, L. bratislava, L. icterohaemorrhagiae, L. grippotyphosa, L. pomona, L. australis, L. hardjo. L. canicola, L. tarassovi, L. bataviae and L. mitis. In cattle the predominant serotype was L. sejroe, in pigs L. pomona, in goats L. pomona, in horses L. grippotyphosa and L. sejroe. In dogs antibodies (probably post-vaccinal) were detected to L. icterohaemorrhagiae, L. grippotyphosa and L. canicola. 5. Q fever A total of 1,728 cattle and 1,351 goats were vaccinated with an inactivated vaccine. The disease was confirmed by the increase of antibody titres. 6. Rabies Oral vaccination of foxes was carried out in two campaigns (spring and autumn) over the whole territory of Slovakia. A total of 1,350,000 vaccine doses were distributed; some 1,370 hunting societies and 82 other organizations participated in the campaigns in all 38 districts in Slovakia. During the period under review, a total of 317,947 domestic animals were vaccinated against rabies. Of these, 312,298 were dogs. Five hundred dogs which had injured people were laboratory examined for rabies and 31 were positive. A total of 270 rabies-positive cases were recorded in 1995. Of these 79.6% were foxes. Occurrence of rabies by animal species in 1995 Domestic animals Dogs Wildlife Cats Foxes 31 20 215 6.2% 0.7% 16.1% -238- 7.

Enzootic bovine leukosis No clinical forms of enzootic bovine leukosis have been recorded in Slovakia since 1992. Solitary occurring ID test positive reactors are slaughtered within 14 days of testing and the remaining animals in the herd are repeatedly re-examined. Out of the total number of serologically examined blood samples, 0.03% were positive. A total of 220,370 samples were laboratory tested, representing 59.3% of the total number of cows. 10. Haemorrhagic septicaemia and other pasteurelloses Of the total number of samples examined, 8.9% were positive in cattle and 12.6% in other animals. 11. Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis The national eradication plan was worked out and has been realized. In 1995, the breeding bulls which had already been vaccinated were re-vaccinated with an inactivated vaccine. Vaccination was also used in some herds according to their disease status. This gave rise to 26,805 vaccinations. In the majority of outbreaks the disease was confirmed on the basis of increased antibodies detected by virus neutralisation test. Diseases of sheep and goats 12. Ovine epididymitis (Brucella ovis) In sheep 8,117 blood samples were examined with Brucella ovis antigen and 3.2% were positive. 13. Caprine and ovine brucellosis (excluding B. ovis) In sheep 13,571 blood samples were examined with Brucella melitensis antigen and were negative. 14. Caprine arthritis/encephalitis The disease has not been clinically confirmed. However, positive titres of antibodies were found in 24 of the 569 samples tested. The percentage of positive findings exceeded 4%. Out of a total of 25,120 goats some 2.2% were examined for caprine arthritis/encephalitis. -239- 15. Maedi-visna The disease has not been clinically confirmed. Antibodies to the maedi-visna virus antigen were detected by immunodiffusion test in 574 samples, representing 14.7% of the total number of samples tested. Diseases of horses 16.

Some 43,000 birds died or were destroyed due to other serovars, isolated in broiler flocks only. In all, 32 serovars were isolated from various animal species. Of these, 24 were isolated from poultry. The most frequently isolated serovar was S. enteritidis (accounting for 6 3 . 3 % of all isolations). In 67.8% of cases it was isolated from poultry, but was also found in almost all other animal species. In 1995 there was a relatively high percentage of salmonella isolated from feeds of plant and animal origin. Vaccination was not used. 6. Coccidiosis The highest rate of positive fecal samples was recorded in pigeons (65.5%) followed by rabbits (53.5%) and poultry (18.4%). 7.

Comments 1. on selected diseases Foot and mouth disease The only foot and mouth disease endemic area is the Kruger National Park and adjoining private nature reserves with buffalo populations. The control is therefore aimed at preventing the virus from escaping from the endemic area into adjacent stock farming areas. 08-93 12-94 11-94 04-94 09-94 12-94 12-94 -242- The northern and eastern borders of the Republic of South Africa and the Kruger National Park, are declared foot and mouth disease control areas in which regular stock inspections at short intervals are carried out by officials of Veterinary Services. Strict movement control of cloven-hooved animals and their products is also applied in this area. One small outbreak of the disease was diagnosed in impala (Aepyceros southern part of the Kruger National Park. melampus) during the year in the South Africa has applied for zoning for foot and mouth disease freedom (without vaccination) as no outbreaks of the disease have occurred outside the Kruger National Park since 1983. The last outbreak outside the controlled area was in 1957. Changes in the vaccination strategy and control zone has been adapted in view of the zoning proposal. 2. Lumpy skin disease Although a very efficient vaccine is freely available, farmers tend to neglect vaccination until the disease poses a serious threat. 3. African horse sickness South Africa has submitted a proposed protocol to the European Union for zoning of African horse sickness. The proposal is to have a disease free zone in the Western Cape peninsula surrounded by a surveillance zone with movement control of horses. 4. African swine fever Three outbreaks of the disease were diagnosed within the African swine fever control area. 33 animals were involved, of which 31 died and two animals were slaughtered. The normal zoo-sanitary control measures were instituted. No commercial piggeries were affected. The outbreaks occurred because the pigs had direct contact with warthogs (Phacochoerus aethiopicus). 5. Newcastle disease The problem has been brought under control by means of adaptation of the vaccination programmes by poultry producers. Proposals have been put to the European Union concerning the export of ostrich products from South Africa. II. LIST B DISEASES Diseases of multiple 1. species Rabies The total increase in rabies cases was from 573 cases in 1994 to 602 cases in 1995. The main area of concern is the Kwazulu-Natal Province where canine rabies is abundant. Rabies in dogs in the rest of the country where sylvatic rabies mainly occurs is within expected limits. However, indications are that the disease is spreading in a north-easterly and south-easterly direction. Positive cases of the canid virus have been diagnosed outside the areas of expected occurrence of this virus. These findings are of major concern as the existing policy for the control of the disease, including the proclamation of rabies control areas, are based on the expected geographical occurrence of the canid virus. The control policy for rabies is currently under revision. -243- Diseases of sheep and goats 2. Caprine and ovine brucellosis (excluding B. ovis) A serological survey was carried out in the Kwazulu-Natal Province during the period of October 1994 to April 1995 following a diagnosis of Malta fever in the owner of a herd of goats in northern KwazuluNatal. Goats were selected from diptanks and farms randomly selected throughout the Province, but the goats in the districts of Ingwavuma, Pongola, Simdlangentsha and Ubombo were bled more intensively. Six foci of infection were found during the serological survey involving 6.266 goats. The prevalence in the positive herds varied from 17% to 100%. The diagnosis was confirmed by culturing milk samples from serologically positive animals. Infected goats were found in only three districts (Ubombo, Ingwavuma and Pongola) and all infected herds fell within a 50-km radius. The current policy is to try to eradicate the disease, because of the serious zoonotic implications and the potential threat to the small stock and cattle in other parts of the country. Further surveys are being conducted in the Kwazulu-Natal Province. Diseases of horses 3. Equine viral arteritis Equine viral arteritis was diagnosed in 1988 for the first time in South Africa in an imported Lippizaner stallion. A country-wide serological survey conducted immediately after that in thoroughbred horses, vielded negative results, and it was concluded that the country was still free from equine arteritis virus (EAV). The Onderstepoort Veterinary Institute conducted a national serological survey in donkeys during the period 1989 to 1993. Seroepizootiological study provided evidence of widespread distribution and indicate long-standing presence and increasing EAV diffusion among the donkey population. A high correlation between the presence or absence of seropositive jackasses and jennies and markedly lower seroprevalence of EAV infection amongst young as compared to sexually mature animals was found. EAV was isolated from semen of naturally infected donkey stallions, and venereal and in-contact transmission of EAV was demonstrated in donkeys. The results of an ELISA and virus neutralisation test confirmed that donkeys and mules have been exposed to the same serotype of EAV which is known to circulate in the horse population worldwide. The RT/PCR confirmed the presence of EAV in different clinical samples collected from naturally or experimentally infected donkeys. About 300 zebra sera of disparate chronological and geographic origins all tested negative for the presence of antibodies against EAV. No serological and virological evidence of EAV infection could be obtained in horses exposed in-contact to experimentally infected donkeys with the asinine strain of EAV. The preliminary result of clinical, serological, virological, transmissibility and abortogenic study, suggest low pathogenicity of the South African strain of EAV for horses. This survey confirms previous indications of a low probability and low risk of transmission of the disease between donkeys and horses. A serological survey will now be conducted in horses in those areas showing the highest number of seropositive donkeys, to confirm the presence or absence of natural transmission from seropositive or infected donkeys to horses. -244- S U D A N INTRODUCTION Sudan has one of the largest livestock populations in Africa. Livestock is raised mainly by nomads and seminomads in the savannah belt, with herds roaming over vast areas in search of grazing and water. The distribution of livestock is correlated with that of vegetation. Improvement of animal health is considered as one of the most important factors in the upgrading of livestock. Control of livestock diseases is the backbone of animal health improvement. Disease prevention and control One of the main animal health functions of the Ministry of Agriculture, Natural and Animal Resources (MANAR) is to control and, if possible, eradicate the major epizootic diseases: e.g. rinderpest, foot ant mouth disease, contagious bovine pleuropneumonia, tick-borne diseases, animal trypanosomiasis, etc. A well-planned programme coordinated and implemented by a strong central veterinary authority, which is assisted by similar, capable authorities at the State level. PARC is a good example of such well-organised disease control programme. The disease control strategy and policy was developed in consideration of the following points: 1. The socioeconomic impact of the disease on the population and national economy. 2. Evaluation of the previous experiences of disease control programmes in order to avoid any of their shortcomings or drawbacks. 3. Possible means of coordinating efforts with neighbouring countries. 4. Practical means of controlling the disease: potent vaccines, organisation of vaccination campaigns which can easily reach the areas of livestock concentrations. 5. Availability of sufficient financial support. 6. Legislation. In 1995 the country faced no serious outbreaks, the major diseases were brought under control and there was reduced incidence of infectious diseases. This was mainly due to: 1. Improved disease control activities through 114 dry season and 86 rainy season vaccination teams, in addition to well-equiped disease investigation and diagnostic units. 2. Increased role played by the private sector in importation, distribution and dispensing of veterinary drugs through newly formed popular pharmacies. 3. Participation of animal owners in the costs of veterinary services offered. 4. The NGOs mainly in the southern part of Sudan were actively involved in disease control activities. Future plan for disease control 1. All diseases to be brought under control with special emphasis on diseases having a socioeconomic impact, namely rinderpest, contagious bovine pleuropneumonia, anthrax, haemorrhagic septicaemia and tick and tick-borne disease. 2. Increase in vaccine production capacity and production of new vaccines. 3. Improved methods for collection, storage and analysis of data and information. 4. Increase in, and promotion of, the disease surveillance capabilities. 5. Setting up of a soundly based communication system and strengthening of contacts with herders and livestock owners. -245- I.

Rinderpest Through an extensive vaccination programme conducted by PARC. 4.728.859 cattle were vaccinated against rinderpest. In a survey of immunity levels, the nine seromonitoring teams found over 70% of positive samples. Rinderpest is completely under control in northern Sudan and efforts were made to stop vaccination in some States in this part of the country. 3. Newcastle disease Newcastle disease continued to be the main threat to the poultry industry in Sudan. II. LIST B DISEASES Diseases of multiple 1. species Anthrax No cases of the disease were recorded in 1995. This is due to successful work carried out by the vaccination teams and the awareness of the community about this serious zoonotic disease. 2. Rabies Rabies continued to be the most important public health hazard which may affect most animal species and humans. Incidence of the disease increased in 1995. A total of 14 outbreaks involving five animal species were recorded. Unavailability of the vaccine in addition to the difficulty of elimination of stray dogs were the main constraint against rabies control in Sudan. 3. Brucellosis There was increased incidence of brucellosis in 1995 involving different animal species. Locally produced vaccine is still in the preparation stage; imported vaccine is restricted to well-stablished farms. There is a plan to launch a brucellosis control campaign supported by the FAO. 07-94 -246- Diseases of cattle 4. Theileriosis Although there is an active tick control programme, which started in 1994, there is increased incidence of the disease and it continued to be the main hazard facing the introduction of foreign breeds to the country. 5. Trypanosomiasis Trypanosomiasis is considered to be widely spread in most parts of the country. A recent trypanosomiasis survey in the tsetse-free zone revealed increased incidence of bovine trypanosomiasis in dairy cattle in this area. Increased efforts will therefore be directed towards chemotherapy. -247- S U I S S E L MALADIES DE LA LISTE A Aperçu général Maladie présente en 1995 Total 1994 1 Maladie de Newcastle Maladies n'ayant jamais été Total 1995 1 Mar 0 Avr 0 1995 Mai Jun Jul Aou Sep 0 0 0 0 0 0 F.P.

L'un est apparu dans un effectif de poules pondeuses, l'autre dans un élevage amateur de pigeons. Trois'cas séropositifs ont été dépistés dans des effectifs importés, encore en quarantaine. Tous les cheptels en quarantaine ont été éliminés, sauf un qui a été réexporté. Aucun autre cas de maladie de la Liste A n'est apparu en Suisse durant l'année 1995. Epidémio-surveillance L'Institut de virologie et d'immunoprophylaxie a procédé à 103 examens virologiques et sérologiques pour le dépistage de la fièvre aphteuse, à 908 examens pour la recherche de peste porcine classique (dont 193 chez des sangliers vivant dans la nature) et à 741 examens de dépistage de la maladie de Newcastle, qui se sont tous révélés négatifs. En ce qui concerne la péripneumonie contagieuse bovine, les examens effectués à l'Institut de bactériologie vétérinaire de l'université de Berne sur 22 lésions pulmonaires suspectes ont tous donné un résultat négatif. II. MALADIES DE LA LISTE B Maladies communes 1. à plusieurs espèces Rage Alors qu'on enregistrait encore 225 cas en 1994, seuls 23 ont été signalés en 1995, tous confinés dans le nord-ouest du pays. Les mesures de lutte ont été les suivantes : une distribution plus dense des appâts contenant le vaccin (25 par km ), une campagne supplémentaire de vaccination orale des renardeaux au début de l'été, et un lâcher immédiat d'appâts par avion suite à l'apparition de cas de rage en dehors des zones de vaccination. 2 03-94 -248- Maladies des bovins 2. Leucose bovine enzootique et rhinotrachéite infectieuse bovine La leucose bovine enzootique et la rhinotrachéite infectieuse bovine ayant été éradiquées au cours de ces dernières années, on a procédé à l'examen d'un échantillon des troupeaux. Ces examens par sondage ont porté sur 4 698 troupeaux, dans lesquels tous les animaux de plus de 24 mois ont été contrôlés. Aucun cas positif n'ayant été décelé, il est permis d'affirmer avec une probabilité de 99 % que la prévalence de la rhinotrachéite infectieuse bovine et de la leucose bovine enzootique dans le cheptel suisse est inférieure à 0,1 %. 3. Encéphalopathie spongiforme bovine Cent onze bovins présentant des troubles nerveux suspects d'encéphalopathie spongiforme ont fait l'objet d'un examen histologique du cerveau. La suspicion clinique a été confirmée dans 68 cas. Depuis l'apparition du premier cas en 1990, 188 cas ont été constatés jusqu'à fin 1995 en Suisse ; sept vaches étaient nées entre le 1 décembre 1990 (date de l'entrée en vigueur de l'interdiction d'affourager des farines d'origine animale aux ruminants) et fin 1991. L'âge moyen des vaches atteintes d'encéphalopathie spongiforme est de 5 ans. e r -249- S W E D E N INTRODUCTION The control programme for enzootic bovine leucosis (EBL) was made compulsory during 1995. The Swedish salmonella control programmes for live animals, eggs and meat were completed. A brief description of these programmes will be found below. I.

Blenta AB is the largest broiler breeder company in Sweden. It is situated in Skâne in the south of Sweden. In the central part of Blenta where the hatchery and the office are situated there are 12 houses (Houses 1-12) with broiler parents in egg production with only 100200 meters between the houses. No other sign of disease was observed and mortality was not increased. House 9 consisted of two pens with parent birds of 37 weeks of age. The drop in egg production started in one pen, but was not observed in the other pen until one week later. Post-mortem examination on birds from House 9 showed no lesions typical of Newcastle disease, only fragile egg follicles in the ovarium. No other flock in the establishment showed any warning signs of disease at that time. Samples for serological testing and virus isolation from House 9 arrived at the National Veterinary Institute (NVI) on 1 November. High titres of antibodies against PMV-1 were detected in the sera with both ELISA and haemagglutination inhibition (HI) and attempts to isolate a virus started immediately. The same day, sera from two younger flocks, of 24 weeks of age, were tested in the abovementioned mandatory routine surveillence programme. Both flocks had even higher titres of antibodies against PMV-1 than House 9. These flocks (situated in Houses 7 and 8) had not started laying eggs and had not shown any signs of disease. Houses 7 and 8 arc situated close to House 9. Virus was isolated three days later from oviduct tissue and identified as PMV-1. The virus isolate was sent to the Central Veterinary Laboratory (CVL), in Weybridge, United Kingdom, for confirmation and pathogenicity test. On 13 November the ICPI was calculated as 1.48 by the NVI and subsequently a formal decision was taken by the SBA to establish a protection and a surveillance zone, in accordance with Council Directive 92/66/EEC. 1956 -250- Due to the suspected positive test results from 11 backyard flocks and from other production units belonging to Blenta AB, the zones were considerably larger than the minimum requirements stipulated in the Directive. From 1 December, the surveillance zone and the protection zone were reduced to 3 and 10 km, respectively, around central Blenta. On 22 December the zonal restrictions were lifted. Since 17 January 1996, the restrictions regarding Newcastle disease have been lifted in all parts of Sweden. All broiler flocks (n=26) delivered from the Blenta hatchery during the weeks before the hatchery was closed were kept under restriction and tested serologically before slaughter. There was no spread of Newcastle disease with these chicks. No clinical signs were registered and all flocks were seronegative. All commercial flocks, including two breeder companies, were tested and found to be free from PMV-1. A large number of backyard flocks (approx. 550) with a number of different avian species were tested serologically with the ELISA test using a dilution of 1:20. Out of more than 500 flocks tested, 41 were found to have PMV-1 antibodies in one or more samples tested by ELISA and 21 of these flocks were also positive to the HI-test. After retesting, 6 flocks were still suspected of having ongoing subclinical PMV-1 infection. Several tests, including attempts to isolate virus, showed that there was no spread of infection within the flock or to adjacent flocks in the neighbourhood. The measures to control the outbreak included the destruction of all live poultry (92,854 hens) in the so-called central unit of Blenta, the destruction of about 1.3 million hatching eggs and 180,000 day-old chicks. These decisions were taken in the timespan 1 November - 14 November. In summary, the presence of the Newcastle disease virus has only been confirmed in one holding (Blenta AB). Within the holding the outbreak has been limited to the so-called central unit consisting of 12 houses with breeding poultry (parent birds producing hatching eggs). Before the outbreak of Newcastle disease in 1995, Sweden had been free from the disease since 1956. Vaccination of poultry against Newcastle disease is not allowed. Since 1984, racing pigeons and show pigeons are vaccinated with a killed paramyxovirus-1 vaccine within the framework of a compulsory national control programme of paramyxovirus infections in pigeons. Since 1992, all breeder flocks have been regularly tested for Newcastle disease within the framework of a mandatory health surveillance programme. II. LIST B DISEASES Diseases of multiple 1. species Aujeszky's disease The Swedish Aujeszky's disease (AD) control and eradication programme is a continuation of a programme initiated in boar stations in 1973. The programme has gradually been extended and, since 1991, has included all swine herds. Since 1994 the control programme is mandatory for all elite breeding, gilt producing and multiplier herds (with > 1 sow). The programme was further supplemented with a mandatory eradication in 1995. The number of clinical outbreaks has steadily decreased (see table). The aim of the programme is to be able to declare Sweden free from the disease in 1996. Number of clinical outbreaks of Aujeszky's 1990 1991 1992 1993 1994 1995 disease in Sweden 1990-1995 10 6 6 0 1 0 The testing scheme consists of herd based sampling and herd and slaughter based monitoring, as described below. In order to declare a herd free from the disease, all animals of more than six months of age have to be serologically tested twice at an interval of between three and six months. In integrated herds with -251 - purchased weaners, 5 % of the fattening pigs are also tested for AD antibodies. On 1 January 1996 all herds taking part in the programme were declared free from AD. A sufficient number of sows are tested in each herd in order to be certain of detecting an in-herd prevalence of 10% with a 9 5 % confidence level. In herds with more than 250 sows, this testing is repeated three more times (i.e. 4 times annually). In addition, all boars (about 300 anually) and approximately 5,000 slaughter pigs are serologically tested at slaughter. If seroreactors are found the herd is immediately closed with a total ban on animal movements from and to the herd. All positive animals are slaughtered as soon as possible and at least within 30 days. All remaining animals over 6 months of age are tested within approximately 4 weeks after the slaughter of the positive animal. Four weeks after the first herd test with a negative result, all animals older than 2 months in the herd are tested again. Diseases of cattle 2. Bovine tuberculosis Control programme for bovine tuberculosis in farmed deer A voluntary control and eradication programme of bovine tuberculosis in farmed deer was started in 1994. The disease was detected for the first time in 1991 when one fallow deer herd was found to be infected with Mycobacterium bovis. Between 1991 and up to the end of 1995, a total of twelve fallow deer herds have been confirmed infected with bovine tuberculosis. One infected herd was detected during 1995. The source of infection was a group of fallow deer imported to Sweden in 1987. The voluntary control programme allows a herd to be declared free of tuberculosis (TB) after the slaughter and meat inspection of all deer kept on the farm followed by reintroduction of deer from a herd declared free from the disease or after three comparative, cervical tuberculin tests with negative results of the whole herd. The test interval has to be at least 3 months and the interval between the first and third test has to be at least 12 months but not more than 24 months. By December 1995. approximately 3 5 % of the deer herds had entered or fulfilled the part of the programme that leads to declaration of freedom from the disease. Movement of deer is only allowed from officially TB-free herds. Other mammals are not allowed to enter or leave a deer herd that is not TB-free. Meat inspection of venison from farmed deer is compulsory. 3. Enzootic bovine leukosis Enzootic bovine leukosis (EBL) has been diagnosed in herds in all parts of Sweden but with a strong concentration in the south-eastern parts of the country. Initially, in the eradication programme, the prevalence of infected dairy herds was 6 . 1 % and the corresponding figure for beef herds was 1.5%. A voluntary control programme was initiated in 1989. In October 1995 the programme was made mandator)' for all bovine herds with own replacement. The aim of the programme is to be able to declare Sweden free from the disease in 1997. A herd can be declared free from EBL if all bovines over 12 months old are tested twice at an interval of between four and eight months with negative results. The sampling will be repeated every second year in order to verify the EBL-free status. If only a few infected animals have been detected, these have to be slaughtered within 30 days, otherwise a sanitation plan is drawn up. Findings at slaughter found indicative of leukosis are examined histologically and serologically to differentiate between the infectious form (EBL) and non infectious forms, 4. Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis A mandatory control and eradication programme for infectious bovine rhinothracheitis / infectious pustular vulvovaginitis (IBR/IPV) was initiated in April 1994. Regular screening of dairy herds through bulk milk tests between 1990 and 1993, indicated a very low prevalence (approximately 0.05%) of the infection. This low prevalence, together with the altered conditions on import control of live animals within the EEA agreement, and the perspective of European Union membership, constituted the basic motives for launching the IBR/IPV programme in 1994. In February 1994, IBR/IPV was added to the list of diseases which are covered by Swedish legislation on epizootic diseases. The aim of the programme is to be able to declare Sweden free from the disease in 1997. -252- All bovine herds, with the exception of specialised fattening herds without own replacement, are covered by the mandatory IBR/IPV programme. All dairy herds are tested twice annually by bulk milk test using an indirect ELISA. Herds with more than 50 lactating cows must be subjected to either an annual serological test of all lactating animals or two milk test annually on pooled samples of milk collected from not more than 50 cows. In beef herds, all animals of more than 2 years of age are subjected to one serological test or milk tests annually. Costs incurred under the control and eradication programme are paid by the government. The total number of dairy herds in Sweden is 17,112 and the number of beef herds approximately 17,000. Within the control programme and up to the end of December 1995, a total of 19 bovine herds have been found to include IBR/IPV-positive animals; 7 of these herds were detected in 1995. Of the 19 herds, 18 are dairy herds and one a mixed herd. In 1995 a total of 190,000 samples from beef cattle were analysed and found to be negative for IBR/IPV antibodies. Any herd found to be positive for IBR/IPV antibodies is immediately placed under restrictions with a prohibition on buying or selling animals other than for direct slaughter. Animals confirmed positive for IBR/IPV antibodies are slaughtered within 30 days and the premises disinfected. All animals in the herd are re-tested at the earliest 4 weeks after the positive animals have been slaughtered. When all animals are negative, another test is carried out 3 months later and the restrictions can then be lifted if all the animals are still negative. Approximately 1,300 bovine animals have been slaughtered as a consequence of the IBR/IPV eradication programme. In three herds, all animals were slaughtered due to either a high prevalence (more than 50%) of infected animals, or practical difficulties in carrying out a sanitation programme. The farmers are fully compensated for direct and indirect economic losses caused by the slaughter of IBR/IPV-positive animals. Diseases of sheep and goats 5. Maedi-visna The first case of maedi-visna in Sweden was reported in 1974. The infection has subsequently spread throughout Sweden. An officially supervised voluntary control programme was initiated in 1993. The programme is based on annual flock samplings of all sheep over 12 months of age and certain obligations and undertakings from the farmers. A flock can be declared free at the earliest after 2 years (3 flock tests) in the programme. The aim of the programme is to declare flock free from maedi-visna, decrease the number of infected flock through sanitation measures or slaughter and prevent the transmission of the disease. At the end of 1995, 2,000 flock were included in the programme and 1,400 had been sampled. Of the flocks sampled, 12.5% were diagnosed as infected with the maedi-visna virus. III. OTHER DISEASES 1. Bovine virus diarrhoea The control programme for bovine virus diarrhoea (BVD) started in the autumn of 1993 on a voluntary basis. The programme is executed by the local livestock associations in cooperation with the state district veterinary organisation and financed through fees paid by the farmers. The programme has met with great interest from farmers all over the country due to the clearly apparent benefits which BVD sanitation brings to the health status and production of any BVD-infected herd. A contract is drawn up between the farmer and the local executive body of the control programme. The farmer has to undertake certain obligations with respect to recruitment of animals and other measures preventing the transmission of BVD infection. No compensation is paid if persistently infected animals have to be slaughtered. The sampling scheme in dairy herds that join the programme consists of bulk milk samples, pooled milk samples of 5-10 primiparous cows or 5-10 individual blood serum samples of young stock of over 15 months. In beef cattle herds the sampling scheme is based on 5-10 individual blood serum samples from primiparous cows or young stock of over 15 months. In order to be declared BVD virus-free, a herd must be sampled twice, at an interval of seven to eleven months, fulfilling one of the following criteria: -253- 1) a low level of BVD virus antibodies in bulk milk samples, 2) pooled milk sample from primiparous cows is antibody negative, 3) the individual blood serum samples are seronegative. The programme also includes rules for buying and selling livestock animals between herds. Up to the end of 1995, a total of 11,370 dairy herds had been affiliated to the programme, that is approximately two thirds of all Swedish dairy herds. Of the affiliated herds, 6,821 herds (60%) have been declared BVD-free. The number of beef herds affiliated to the programme is 2,400 out of a total of approximately 17,000 beef herds. Salmonella infections The overall aim of Swedish salmonella control is that animal products delivered for human consumption shall be free from salmonella. This aim is based on the concept that only an extremely small proportion of the primary production and animals sent for slaughter is infected/contaminated with salmonella. The strategies to reach this aim are: 1. To prevent salmonella contamination of all parts of the production chain. 2. To monitor the production chains at critical points. Sampling programmes for cattle, swine and poultry are part of this monitoring. 3. To undertake actions necessary to fulfill the objectives of the control when salmonella contamination occurs. In 1995 the programmes for swine and cattle were implemented by slaughterhouse monitoring programmes. These programmes survey swine and cattle herds and determine with a high degree of precision the prevalence of salmonella-contaminated carcases and verify that the prevalence of salmonella-infected animals sent to slaughter is very low. The sample size is sufficiently large to detect a prevalence of salmonella of 0 . 1 % with a 9 5 % confidence level. The salmonella sampling programme for live poultry was also changed in 1995. The most significant alteration concerns flocks with layers. All flocks in establishments marketing eggs, now have to be checked for salmonella three times per production period. The sampling programmes as well as the surveys that are regularly carried out are prove that the prevalence of salmonella is less than 1% in all food producing animals. -254- T A I P E I C H I N A INTRODUCTION The preventive and control measures for existing animal diseases have not been changed in recent years. A regulation, Procedures for Recognition of Disease-Free Status of a Foreign Country, was enacted from 16 May 1992. Procedures are provided for handling the application of a foreign country for recognition of its status of freedom from a given animal infectious disease. A computerized animal disease reporting system has been in operation since 1985. A revised national programme was started in 1993 to strengthen the disease surveillance system, especially with regard to the monitoring of exotic animal diseases. A regulation on animal quarantine requirements for live fish and their products was introduced in October 1994. The Legislative Branch approved the revised Veterinarian Act and Animal Health Act in January 1995 and January 1996, respectively. I.

Result indicates a continuous decrease in incidence. A programme has been set up in order to eradicate the disease. 2. Newcastle disease Thirty-six farms and 753,150 chickens were affected in 1995. An intermediate type vaccine was used for the control of the disease. The cooperative control programme was carried out with the Poultry Farmers Association, and monitoring of serum titres against the disease was conducted to help poultry farms to adjust their vaccination programmes in order to ensure the high immune status in the poultry population. 09-94 04-91 -255- II. L I S T B D I S E A S E S Diseases of multiple 1. species Aujeszky's disease Since 1989, a project has been under way to help purebred farms to build up their own specific-pathogenfree herds. In order to eliminate naturally infected pigs from herds immunised with gl-dcleted inactivated pscudorabies vaccines, a serological monitoring system was set up. The gl-dcleted live vaccines were recently approved for use in herds with a disease problem. Diseases of cattle 2. Bovine brucellosis No positive reactors have been detected in any dairy herds since January 1989. This included the 67,268 serum samples, from all dairy farms, tested in 1995. 3. Bovine tuberculosis The test and slaughter scheme and restrictions on cattle movements from farms with positive reactors were maintained. Twice a year, a tuberculin test is conducted for the early elimination of all positive reactors. In 1995, 124,365 dairy cattle were tested, resulting in the identification of 1.021 reactors. 4. Infectious bovine rhinotracheitis/infectious pustular vulvovaginitis The vaccination programme was recommended to control the disease. Diseases of poultry 5. Fowl cholera The number of cases was not significantly different from that of previous years. The prevention of fowl cholera was continued by vaccination. 6. Infectious bursal disease (Gumboro disease) An epizootic of virulent infectious bursal disease was first recorded in February 1992. An intermediatetype vaccine was used for controlling the disease. 7. Mycoplasmosis (A4, gallisepticum) A nation-wide serological survey by serum plate agglutination test conducted by the health certification scheme revealed that all grandparent farms remained free from the disease in 1994. It was quite difficult to evaluate the real situation regarding infection in parent stock breeding farms because bacterins were used in some of them. Chronic respiratory disease caused by hi. gallisepticum is one of the economically important diseases in the poultry industry. 8. Pullorum disease (Salmonella pullorum) Breeding flocks have been tested regularly in accordance with the national pullorum control programme. In 1995, a total of 159,754 chickens were examined and 14,610 reactors were slaughtered. Diseases of fish In addition to Monodon baculovirus infection of grass shrimp, diseases of economic importance include such as ich, velvet disease, streptococcosis and nocardiosis. A national programme to provide diagnostic services and extension of disease prevention was carried out to minimize economic losses. -256- T A N Z A N I A INTRODUCTION Tanzania is shifting from a centrally planned economy where the state owned institutions dominated the economy, to a situation in which private institutions and individuals are being actively encouraged to participate. The strategy is for the government to provide a conducive economic climate for producers and to rely on market forces to set prices and on diversification of marketing channels. Within the agricultural sector a new mission is being adopted in line with the current changing economic policies of liberalisation. The new agricultural policy is geared towards promoting and sustaining an enabling environment for growth in production, trade and investment, recognising the government's role in research, extension, regulatory services and information management. The new thinking calls for strengthening capacity building for the Crop and Livestock (Agricultural) Information System as a link between the public and private sectors. The livestock industry in Tanzania has enormous potential for increased production, both in absolute numbers of animals and increased productivity of the existing numbers. The country has a potential capacity for about 20 million cattle, but the present population is approximately 15 million. There is therefore a large base on which to build and plenty of scope for expansion. A modest change in the management of the traditional herd in terms of improved nutrition, disease control and improved breeding can increase production to meet the rise in local demand for livestock products. Major investments in marketing and infrastructure in the livestock sector could, in the long run, become an important foreign exchange earner. Constraints to livestock development Many of the constraints for developing the livestock industry are common to other sectors of the economy, including lack of finance, poor communications and inadequate skilled manpower. Specifically, the main constraints hindering the development of the livestock industry in Tanzania are: . . • . . . . . . . . . . . . land tenure deficient input supply price policies poor transport and marketing infrastructure poor management breed conservation lack of improved breeds lack of mineral/protein supplement poor utilisation of crop residues poor quality of pasture/forage inadequate nutrition soil erosion overstocking water scarcity and drought erratic rainfall diseases lack of credit non commercial altitude of livestock owners. -257- Sírategies for sustainable livestock industry The main strategy for sustaining the livestock industry in Tanzania is to increase investment levels by mobilising local and foreign resources through: . . . . . . . cost recovery for sustainability establishment of Livestock Development Fund privatisation of the sector improved credit schemes establishment of livestock keepers' associations community-based animal health schemes human resource development integrated use of natural resources for sustainability development and improvement of cost-effective extension packages. Veterinary Sennces Effective animal health care is crucial to the development of the livestock industry in Tanzania. In order to increase productivity of the animal population and to protect human health, the Ministry of Agriculture through the livestock department gives special emphasis to the practical and cost-effective control of livestock diseases. To minimise the spread of diseases through livestock movements, a zoosanitary inspection service will be established and animal disease regulations are being reviewed. Diagnostic and disease surveillance facilities at all levels will be rehabilitated to operate in conjunction with the extension service. This includes strengthening capacity building in the livestock department to produce reliable livestock information through a recently established Epidemiology Unit. Veterinary clinical services in urban and peri-urban areas are progressively being privatised through a SelfEmployed Veterinarians Scheme (SEV) funded by the European Union under PARC. Supply and distribution of veterinary drugs and acaricides have already been taken over by the commercial sector but vaccines and veterinary biologicals will continue to be distributed through official channels. The government will have to enforce legal requirements for safety, efficacy and potency. Livestock information system planning in Tanzania The current livestock information system in Tanzania is inefficient, poorly organised and hence characterised by limited knowledge of producer/user demand for livestock statistics, lack of regular publications and distribution of livestock information, lack of communication networking, inadequate logistic support and, last but not least, inadequately trained personnel in livestock data collections storage and analysis. These shortfalls have resulted in a lack of information flow to decision makers in livestock, including producers, planners, donors, researchers, world bodies (FAO, OIE, WHO, WB, WTO, IFAD, SADC. etc.) and the government itself. This has led to weaknesses in livestock policy formulation, marginalisation of livestock in terms of resource allocation, inefficient extension and research services to livestock producers. The consequences have been low animal productivity, low private and public sector investment, environmental degradation and reduced impact on donor-funded projects. We are revising the country's livestock information management system so that it can be strengthened to produce reliable information related to livestock health, production and marketing. We have requested the assistance of FAO through its Technical Cooperation Programme (TCP) to assist the Livestock Division of the Ministry of Agriculture to strengthen Livestock Information Networking. Through a Livestock Information Management Project (LIMP), it should be possible to train our national staff in the new information technologies and software like Epi-Info, HandiSTATUS and Epi-Map. We would appreciate being considered for support by the OIE, FAO, IICA and other International Organisations in the pilot programme for developing national surveillance systems. -258- I.

These were last reported in the late 1980s. 1. Foot and mouth disease Foot and mouth disease remains enzootic in many parts of the country where livestock keeping is a major activity. Unfortunately, the Central Veterinary Laboratory, Temeke does not have the capability to do foot and mouth disease virus typing, hence the epizootiology of the disease in the country is largely unknown. 2. Rinderpest The occurrence of rinderpest in the neighbouring Tsavo National Park in Kenya poses a threat to livestock and game animals in Tanzania. However, judging from field observations and serological prevalence, slaughter inspections and clinical and post-mortem examinations indicate that Tanzania has been free from the disease since the last outbreak in 1982/83. Annual vaccinations and sero-surveillance have been going on for the past ten years or so and we are probably now in a position to rethink our position to request OIE to facilitate Tanzania's declaring herself free from rinderpest, at least south of the central railway line, initially. 3. Contagious bovine pleuropneumonia Recent outbreaks of contagious bovine pleuropneumonia (CBPP) south of the central railway line in Tanzania clearly indicate a worsening situation, especially insofar as the southern African region is concerned. The government of Tanzania, with assistance from the donor community, has taken the necessary steps to control and contain the disease by conducting periodical mass vaccinations in the affected zones. These vaccinations combined with restrictions on cattle movements and slaughter of sick animals has apparently resulted in reduced mortality due to CBPP. Disease monitoring, which includes prompt reporting and close follow-up in all abattoirs and slaughter slabs throughout the country is an important component of CBPP control strategy in Tanzania. This has helped in the zoning and evaluation of the epizootiological status of the disease in the country. The urge for cost sharing due to lack of campaign funds, lack of a -259- reliable diagnostic test for CBPP and the unavailability of good quality vaccines are some of the problems we are facing in controlling and containing the disease. 4. Lumpy skin disease Lumpy skin disease is not currently an economically important disease in Tanzania. In the whole of 1995 there were no confirmed outbreaks. 5. Newcastle disease This is the most important disease of poultry in Tanzania, principally affecting traditional, backyard flocks. Recent studies have shown that healthy village chickens carry Newcastle disease virus and both virulent and avirulent strains have been isolated. II. LIST B DISEASES These are probably the most economically significant diseases of livestock in Tanzania. Vector-borne diseases, and especially theileriosis, continue to be the main cause of death for large ruminants. The livestock department is expected to intensify monitoring and evaluation of these diseases through further research and extension support. On-farm trials continue to be carried out to develop community-based vector control methods to improve cost-effectiveness. Of special importance are rabies, anthrax, brucellosis, tuberculosis and salmonellosis, which are all zoonoses occurring sporadically throughout the country. Apart from controlling these diseases in the livestock populations, the Ministry of Agriculture will intensify its inspection and regulator}' services in veterinary public health to ensure quality and safety of foods of animal origin. -260- T C H A D INTRODUCTION Le Tchad, pays d'élevage par excellence, cherche des voies et moyens pour réorienter sa politique en la matière. C'est ainsi que des activités diverses ont vu le jour, ceci dans le but d'amener nos éleveurs et agropasteurs à se prendre progressivement en charge pour mieux gérer leur patrimoine. Ces activités sont traduites dans les faits par : - La privatisation de la prophylaxie de masse et des activités curatives sur toute l'étendue du territoire, y compris les zones hors cordon. Le nombre de vétérinaires installés en privé passe donc de 20 en 1994 à 26 en 1995, de sorte que les deux tiers du territoire national sont couverts. - Les pharmacies vétérinaires et dépôts pharmaceutiques se sont multipliés pour faciliter l'accès aux producteurs, etc. Ceci étant, dans un proche avenir, les agents de l'Etat seront amenés à créer leurs propres cliniques, élevages, etc. Un réseau de surveillance des maladies, dénommé "Réseau d'épidémio-surveillance de maladies animales au Tchad" (REPIMAT), a été créé dans le cadre de la nouvelle politique de développement de l'élevage. Ce réseau, qui est le fruit de la collaboration entre le directeur de l'élevage et le Laboratoire de Farcha, surveille des maladies à impact économique et/ou hygiénique, à travers des agents de terrain formés à cet effet. Il surveille essentiellement la fièvre aphteuse et quelques viroses des petits ruminants. Certes, certaines maladies sévissent à travers le pays, mais les moyens de surveillance font défaut. Quelques ébauches timides de surveillance sont en cours. I.

On utilise la chimiothérapie pour lutter contre les complications bactériennes. 2. Peste bovine Compte tenu de la menace de cette maladie à partir de l'Est du pays, un cordon sanitaire fut mis en place. Ce cordon est long de 1 000 km du nord au sud et profond de 4 000 km à l'intérieur du Tchad. Les activités vaccinales et de surveillance de routine y sont renforcées et prolongées plus que celles du reste du pays. La vaccination contre cette maladie est rendue obligatoire par le Gouvernement. C'est une maladie à déclaration obligatoire dans la sous-région. Tout bétail à l'exportation doit être vacciné, porter une boucle à l'oreille et être accompagné d'un certificat zoosanitaire international. 3. Péripneumonie contagieuse bovine Les méthodes de surveillance de routine de cette maladie sont appliquées sur toute l'étendue du territoire. La vaccination annuelle est laissée aux mains des praticiens privés. 4. Clavelée et variole caprine Ces pathologies, qui ont été diagnostiquées au laboratoire, ne connaissent pas de vaccination.

More border provinces were announced as international animal quarantine stations in the gazette. As a result, the number of international animal quarantine stations increased from 28 to 38. Cattle and buffalo from neighbouring countries must enter only at specific entrances designated by the Director General of the Department of Livestock Development (DLD), Ministry of Agriculture and Cooperatives. The quarantine period for imported animals from neighbouring countries at an approved quarantine centre was extended from 10 to 21 days prior to entry into the country. In order to distinguish between local cattle and buffalo and imported animals, a special code and different coloured ear tags were introduced. I.

One more strategy on establishing bilateral cooperation between Thailand and neighbouring countries was added to the aforementioned strategies in 1995. According to the FMD information centre, the incidence of FMD outbreaks decreased by 8 0 % from 1992 to 1995. The Department of Livestock Development received a national budget to expand the FMD vaccine production plant to produce 33 million doses of trivalent vaccine in 1996. To improve the efficiency of FMD diagnosis, which will consequently promote epidemiological work, FMD diagnostic facilities were set up in two Regional Laboratories in the north eastern and southern part of Thailand, in addition to the FMD centre, National Institute of Animal Health and the Regional Laboratory in the north. A new technique, focusing on molecular work, is being set up at the FMD centre. In 1995, 12-94 12-94 12-94 12-94 -263- the DLD received financial and technical assistance from FAO to strengthen animal movement control along the border in northern and north eastern Thailand. The project initiated bilateral cooperation between Thailand and Cambodia, Laos and Myanmar by holding a workshop between the authorities concerned to discuss policy and possible procedures to improve animal movement control across borders. The DLD in collaboration with a team from universities is conducting a project to evaluate the on-going FMD Control and Eradication Project. 2. Classical swine fever (hog cholera) As pig production in Thailand is mostly based on an intensive system, each farm is responsible for its own vaccination programme under the close supervision of field veterinarians. An intensive study to investigate the epidemiological characteristics of hog cholera in Thailand is being conducted by the National Institute of Animal Health, which will subsequently become the guidelines for the planning of disease control and eradication. To control hog cholera outbreaks occurring in village-based pig farms, vaccines will be provided free of charge by the division of Disease Control of the DLD. 3. Newcastle disease There have been no reports of outbreaks of the disease during the past 12 months. A strict and well organised Newcastle disease vaccination campaign has been undertaken throughout the areas where poultry is raised. In 1995, the Newcastle Free Zone Project was implemented in 31 provinces for the purpose of exporting frozen chicken meat to other countries. II. LIST B DISEASES Diseases of multiple 1. species Aujeszky's disease Both large-scale and small-scale pig producers have been advised to vaccinate against the disease. 2. Leptospirosis Farmers with herds that have tested positive for leptospirosis have been advised to treat the affected animals with antibiotics. 3. Rabies In 1995, the Government provided the DLD with financial support for the purchase of four million doses of rabies vaccine from a private manufacturer. The DLD itself still produces as many as 300,000 doses per year. Rabies vaccine production by the DLD will not be increased above present levels. A total of 4.3 million doses of rabies vaccine were provided free of charge for the vaccination of pets in rural areas where farmers were not in the habit of vaccinating their animals. The Bangkok Metropolitan Administration also provided vaccines to immunise animals in the Bangkok area. In 1995, meetings were held between the Ministry of Health, Ministry of the Interior and the DLD to discuss strategies on the Rabies Vaccination Project. The DLD will be responsible for the budget to provide total vaccines and the other bodies will provide support and information for an epidemiological report to establish a rabies-free zone. A total of 4,001,555 dogs were vaccinated against rabies. The methods pregnancies were injection of progesterone (560,832 doses), spaying (21,890 (110,195 animals). In addition, training sessions for volunteers were held in country. Altogether, 65,310 persons were trained in 1995.

Bovine brucellosis Brucella abortus strain 19 vaccine is used to induce immunity in young female animals under one year old. A brucellosis eradication programme is conducted in herds owned by the government and larger private farms. These farms will eventually be accredited as brucellosis free. The tests used to diagnose brucellosis are the rose bengal (rapid plate) plate agglutination test, tube agglutination test and complement fixation test. 6. Bovine tuberculosis A tuberculosis (TB) eradication programme is being conducted along with a brucellosis eradication programme in the farms mentioned above. Testing and culling of positive reactors is the strategy applied for the accreditation of TB-free herds. 7. Haemorrhagic septicaemia In 1995, an oil adjuvant vaccine developed by the division of Veterinary Biologicals, DLD, was used as a substitute for the former aluminium hydroxide vaccine. Owing to the property of the adjuvant vaccine to provide 12 months' immunity, the vaccination campaign for cattle and buffalo is being carried out on a yearly basis. -265- T R I N I D A D A N D T O B A G O I.

Of ten suspected cases submitted to the Veterinary Diagnostic Laboratory, seven proved positive by fluorescent antibody test, histological examination and mouse inoculation test. Ring vaccination procedures were instituted together with vampire bat control measures. Vampire bat biting was low. There is an on-going vaccination programme for bovines and rural equids, and import control regulations with a dog and cat quarantine station. There is an on-going programme for a census of vampire bat biting of livestock, wth follow-up work on: a) mist-netting around cattle; b) surveys of vampire bat roosts in hollow trees and caves; c) paint and release techniques for captured live vampires, using anticoagulants; and d) destruction of vampire bats in known roosts. -266- T U N I S I E INTRODUCTION Aucun événement sanitaire particulier n'est à signaler au cours de l'année 1995. Il est à noter qu'à la fin de l'année 1995 une étude portant sur la santé animale a été confiée à un cabinet de conseil avec la participation de trois consultants internationaux. Cette étude, qui sera achevée en 1996, porte sur les points suivants : • responsabilisation des éleveurs par la création d'une Association de défense sanitaire ; • privatisation vétérinaire par l'octroi de mandat sanitaire aux vétérinaires privés pour la mise en œuvre de prophylaxie collective ; • optimisation du dispositif de prévention et de lutte contre les maladies animales par la mise en place d'un réseau d'épidémio-surveillance relatif à : - la déclaration des maladies réglementées, le suivi des maladies non réglementées, la surveillance aux abattoirs, les élevages sentinelles.

Brucellose La vaccination systématique des femelles bovines, ovines et caprines contre la brucellose (souche B 19 chez les bovins et souche Rev-1 chez les petits ruminants, administrée à dose réduite par voie conjonctivale) s'est poursuivie au cours de l'année 1995. C'est ainsi que 172 130 bovins (soit 45 % de la population femelle) et 1 148 171 petits ruminants ont été vaccinés au cours de cette campagne. Ces vaccinations ont permis de réduire de façon notable le nombre de cas déclarés de fièvre de Malte chez l'homme, qui sont passés de 477 en 1994 à 182 en 1995. 3. Tuberculose bovine Le programme de lutte contre la tuberculose bovine s'est poursuivi en 1995 : - 2 151 troupeaux ont été contrôlés par la tuberculination de 36 673 animaux ; les animaux abattus dans le cadre de ce programme sont au nombre de 475. -268- T U R K E Y INTRODUCTION Turkey has implemented comprehensive programmes on animal health and disease eradication. Control of foot and mouth disease (FMD) has become a high priority in recent years. Control programmes are supported by adaptive research, extension and a functional diagnostic laboratory network. Animal vaccine production including quality control and monitoring of immunity is being developed to meet our needs. An animal disease surveillance programme for FMD, rinderpest and other infectious diseases is being carried out. I.

Vaccination, quarantine and control of animal movements are being applied to control the disease. Stamping-out policy has been approved for application in the planned regions. FMD is endemic in Anatolia (virus types Oj and A ) . 2 2 Thrace region Thrace was declared free from FMD in 1991 (OIE Disease Information, Vol. 4, No. 1, of 4 January 1991). This zone comprises the European part of Turkey, with the following five provinces: European part of Istanbul, European part of Çanakkale, Tekirdag, Kirklareli, Edirne. It has about 454,425 cattle and buffaloes as well as about 851,465 sheep and goats. No vaccination was carried out in Thrace until the occurrence of an outbreak in Ulukonak village in Kirklareli province, which was reported on 12 March 1995. In March 1995, all susceptible stock within a 10-km radius of the infected village were vaccinated with bivalent (O + A) FMD vaccine. 12-94 04-93 12-94 04-94 -269- A contingency plan to control the disease was prepared to react appropriately in the event of an FMD outbreak in Thrace. The legal regulations were prepared fo the application of the stamping-out policy. However, this could not be implemented because of financial constraints. Based on a suggestion made at the Alexandrepolis meeting, we checked 201 cattle sera from nine villages, of which 186 could be diagnosed. The average percentage of positive titres (186 sera) for virus types 0 , , A and A + 0 ¡ was 3.7%, 2.6% and 2 . 1 % , respectively. 2 2 2 2 Subject to further discussion, we intend to start a blanket vaccination campaign in Thrace lasting two years, and then to return to a stamping-out policy. At present, the risk of outbreaks seem rather high and funds for compensation may not be sufficient. The Western Buffer Zone of Anatolia This area includes 14 provinces: the Asian side of Istanbul and Çanakkale, Kocaeli, Adapazari. Bursa, Yalova, Balikesir, Izmir, Manisa, Bilecik, Bolu, Eskisehir, Kiitahya and Usak. All cattle are vaccinated twice and sheep and goats once a year in this region. Seven million bivalent doses of FMD vaccine against types Oj and A are necessary for this region. 2 2 Outbreaks are dealt with in accordance with law No. 3285, which makes provision for temporary quarantine, transport restrictions, ring vaccination, disinfection, etc. There is a strong movement of beef cattle from the eastern part of Turkey to the consumer centres in western and central Anatolia. A number of control stations (Giresun-Centre, Tokat-Resadiye. SivasCentre, Malatya-Karakavak, K. Maras-Pazarcik, G. Antep-Nizip) have been set up along a north-west line stretching from Giresun to Gaziantep in order to check livestock being transported from the east towards the Western Buffer Zone. Some animals, moved from the Western Buffer Zone to Thrace region, must have stayed in the Western Buffer Zone at least six months. Vaccinations carried out in 1995 Area Large ruminants Small ruminants Total Western Buffer Zone 1,933,622 2,891.077 4,824.699 Residual Anatolia 2,156,807 1,759,761 3,916,568 Total 4,090,429 4,650,838 8,741,267 FMD in the Western Buffer Zone 1994- 1995 Year No. of outbreaks No. of cases in large ruminants No. of cases in small ruminants 1994 21 75 16 1995 8 33 0 Other provinces of Anatolia In accordance with vaccine availability, vaccinations were carried out in areas along the main east-west livestock transportation routes, in certain project areas, and on private request of farmers. A total of 2,156,807 large ruminants and 1,759,761 small ruminants were vaccinated in 1995. FMD type O is widespread in Anatolia. Ring vaccination, strategic vaccination and quarantine measures are being applied. It has been planned that all cattle and buffaloes in the country will be vaccinated twice and all sheep and goats once in 1996. -270- 2. Rinderpest An outbreak of rinderpest was reported in south-east Turkey on 15 October 1991. This was the first occurrence of rinderpest in Turkey since 1969. The country safeguarded its southern and south-eastern borders against the entrance of rinderpest and other diseases. A rinderpest immunisation zone approximately 20 km in depth was maintained. Disease surveillance and animal movement controls against ingress of animal disease were implemented. Nineteen outbreaks of rinderpest were reported in 1991. In 1992, 1993 and 1995, no outbreaks were reported in Turkey. In 1994, one outbreak of rinderpest was reported. On 5 January 1996, one outbreak occurred. Since the recurrence of rinderpest in Turkey, vaccination campaigns have been conducted every year for the protection of the national animal population. Year No. of vaccinated animals 1992 11,178,791 1993 10,634,636 1994 11,664,420 1995 11,457,063 In 1992 and 1993, after the national mass vaccination against rinderpest, a serological survey was conducted to determine the efficiency of vaccination. Mean prevalence of rinderpest antibody was as follows: 3. Year Mean prevalence of rinderpest antibody (%) 1992 70.91 1993 74.00 1994 70.00 1995 73.70 Sheep pox and goat pox Preventive vaccinations were carried out as in previous years on the whole. In the vaccination programme, priority was given to the regions with a high sheep population and the common border areas with the neighbouring countries where this disease occurs. Sheep in villages and farms along the common borders with Iran, Iraq and Syria have been vaccinated against sheep pox to create a sufficient disease-free zone. Strict sanitary measures have been applied, animal movement restrictions imposed and control has been continuously practised. 4. Newcastle disease In Turkey, Newcastle disease has not yet been eliminated in small flocks in villages but has been eliminated in industrial level farms. Preventive vaccinations have been very effective and have therefore been accorded great importance in the control of Newcastle disease. The economic losses due to Newcastle disease have been decreased to a minimum through systematic annual vaccination and strict sanitary measures. Training of poultry producers is developing and they report the cases they detect. -271 - II. LIST B DISEASES Diseases of multiple 1. species Anthrax Susceptible animals in areas where anthrax has occurred previously and those in other places subject to infections have been vaccinated with M. Sterne vaccine. Animals intended for export to neighbouring countries have to be vaccinated before dispatch. 2. Rabies It is a priority task of all those responsible to inform the population and to recommend annual protective vaccination for cats and dogs. There are detailed provisions to be observed in the case of suspected rabies. In any case of rabies or suspected rabies the official veterinarian must be notified. If anybody has been bitten under suspicious circumstances, the doctor must be notified. Vaccination of pets and destruction of stray dogs, cats and carnivorous wild animals are the essential control measures used in combating the disease. A continuous control programme is applied against rabies. The disease is observed generally in the forest areas in winter, when there is a high population of wild animals. An oral immunisation project has been developed with the cooperation of the EC. This project is applied in the Thrace region to stray dogs. 3. Brucellosis A national control and eradication project has been put into application since the beginning of 1984. This project has been planned for being completed in 26 years. According to the plan of the project. Turkey has been divided into five regions, and according to the plan of operation all female calves of 4 to 8 months of age are to be vaccinated with S 19 vaccine and vaccinated animals are to be ear-tagged and registered. All lambs and kids are being vaccinated with Rev. 1 vaccine. All breeding stock is being bled for laboratory testing; diseased animals are slaughtered and their owners compensated. Animals suffering from abortion should be blood-sampled for laboratory examination; positive reactors should be slaughtered and the owners will be compensated. Based on a serological survey carried out in 1991, seroprevalence of Brucella abortus was 1.01% and B. melitensis was 1.83%. As a result of vaccination of adult cattle and sheep applied in Thrace since 1991. seroprevalence of B. abortus decreased of 1.06% and seroprevalence of B. melitensis decreased of 0.6% in 1994. Since these results are satisfactory, vaccination of adult animals will be undertaken gradually in Anatolia. Diseases of cattle 4. Bovine tuberculosis In governmental and some private farms (holding five or more head of cattle), systematic tuberculin tests are carried out. The control system for tuberculosis includes tuberculin application, laboratory test, slaughtering of reactors with compensation and quarantine measures. Intradermal (PPD mammalian, avian and johnin) tuberculin tests are used. In 1995, 1,574 animals were tested, of which 13 were positive. A Regional Eradication Programme commenced in 1992. starting with the Thrace region. 5. Theileriosis Recently, theileriosis became an important disease of imported animals. An attenuated tissue culture vaccine has been prepared for theileriosis. -272- Diseases of poultry 6. Salmonellosis Salmonellosis is a notifiable disease in Turkey. Salmonellosis control programmes, which also include specific rules for management, are currently applied in hatcheries and parent stocks in our country, with a health certificate being issued to those that are free from salmonella. If salmonella of any serotype is isolated, the flock is slaughtered. In addition, a control programme (especially for Salmonella enteritidis and S. typhimurium), parallel to WHO's salmonellosis control programme that includes slaughterhouses, feedstuffs, feed production units, breeding flock units and selling places, will be applied. It will be put into application as soon as possible. In 1995, a total of 319,353 poultry were tested for S. gallinarum. Poultry farms found to be free from S. gallinarum, S. pullorum, Mycoplasma gallisepticum and M. synovia and in a satisfactory sanitary condition are reported to the relevant institutions, establishments and producers through a quarterly bulletin. III. OTHER DISEASES Parasitic Diseases Distomatosis, strongylosis, piroplasmosis and hypodermosis of cattle are the important parasitic diseases. Anaerobic Diseases In this group, enterotoxaemia, black disease and blackleg are of major importance from the point of view of animal health in Turkey, and are the subject of annual preventive vaccination campaigns. Preventive vaccinations generally involve inoculation of sheep in the infected areas or in regions where the diseases might occur. Economic losses caused by anaerobic diseases have been reduced to a minimum level thanks to systematic vaccination. -273- U G A N D A INTRODUCTION The main mandates for the Veterinary Department remained as follows: 1. Investigation and control of epizootic and other major livestock diseases. 2. Detection and control of zoonotic diseases in livestock. 3. Provision for the welfare of animals. The above were executed through planning, policy generation, supervision of field staff to implement the departmental mandates and direct implementation of National Projects / Programmes. The main changes were basically geared towards improving the delivery of Animal Health Services in which there was a shift towards effective epidemiological^ oriented field disease investigations and cost-effective control strategies, coupled with an attempt to provide ample water for livestock to forestall dry period movement and hence disease spread, improvement of quarantine facilities, and initiation of more effective Veterinary Inspection Services for import/export. The laboratory diagnostic services in the country were boosted with vital equipment. - The above activities were performed through the following four divisions: - Diagnostic Services and Epidemiology - Disease Control - Public Health and Marketing - Regulations and Inputs.

In future, we intend to improve the Epidemiology Unit to conduct active surveillance to help evaluate disease status through surveys. Principal changes and general methods of control/eradication: Emphasis has been laid on information about diseases, disease effects and general control measures through extension staff. Headquarters staff have frequently toured all districts to address civic leaders and farmers on these subjects. Increasingly, the role of effective quarantine and movement limitation is being seriously addressed at all levels. The other main control measures are mass vaccination for vaccinable diseases. Vaccinal coverage and vaccine viability maintenance were also studied. Rinderpest, contagious bovine pleuropneumonia, foot and mouth disease, lumpy skin disease and Newcastle disease were the vaccinable diseases in List A. Eradication is still far off, in view of the frequent unauthorised communal grazing of cattle. We shall aim first to achieve control, then attempt eradication as farming systems improve. Comments on selected 1. diseases Foot and mouth disease Foot and mouth disease (FMD) incidence, the geographical area affected and the number of cattle afflicted increased. FMD virus type SAT 2 virus isolated early in the year. By the end of the year, further samples had been dispatched for culture, isolation and typing. 2. Contagious bovine pleuropneumonia The endemicity of contagious bovine pleuropneumonia continued with sporadic outbreaks, especially in north-western and north-eastern communal/semi pastoral farming areas. 3. African swine fever African swine fever exacted a heavy toll due to mortality in two central region districts and one eastern region district where pig farming is a major contribution to the economy. 4. Newcastle disease Newcastle disease, which is enzootic in local poultry (i.e. non commercial farming), continued to be reported, occasionally spilling over into susceptible inadequately vaccinated birds to cause sporadic outbreaks (confirmed). II. LIST B DISEASES Diseases of multiple 1. species Anthrax Anthrax and blackquarter are sporadic and are controlled via quarantine and vaccination. 2. Rabies Rabies is a main threat in Uganda, being a disease of animals and also being a zoonosis. The disease is still endemic due to various epidemiological factors. However, a multi-sectorial approach educating farmers and communities on the dangers and control methods are starting to bear fruit. -275- Diseases of cattle 3. Bovine brucellosis Bovine brucellosis is sporadic or enzootic in herds according to the situation. Through studies and surveys, the prevalence in various districts is being mapped. Control is via culling and vaccination. 4. Trypanosomiasis Trypanosomiasis and tick-borne diseases are endemic due to environmental factors. Control is through various strategies depending on the production capacity of the breeds. Nationally, the Tsetse Department is responsible for reducing tsetse fly and tick populations to an acceptable level. Diseases of poultry 5. Infectious bursal disease (Gumboro disease) Infectious bursal disease (Gumboro disease) is increasingly becoming a second major poultry killer, especially in commercial poultry farms. -276- U N I T E D A R A B E M I R A T E S INTRODUCTION The Animal Department carries out all activities related to animal health and production and veterinary public health, including veterinary inspection services, preventive treatment, and control and eradication of animal diseases. A survey of equine diseases was carried out on 304 samples collected from stables throughout the country. The test results demonstrated freedom from List A and B diseases of horses. I.

The disease is controlled by strict quarantine, annual vaccination and movement control. 3. Peste des petits ruminants Peste des petits ruminants was diagnosed some years ago. Mass vaccination was performed. 4. Sheep pox and goat pox A few cases were reported in different Emirates. Disease control is by annual vaccination. 02-94 03-93 07-94 11-94 10-94 -277- II. LIST B DISEASES 1. Bovine babesiosis and theileriosis There were many outbreaks of theileriosis and other tick-borne diseases among both local and foreign breeds. The latter were severely affected. The disease is usually brought under control only by tick control and the treatment of affected animals. 2. Equine viral arteritis Survey results in the horse population demonstrated freedom from equine viral arteritis. There was, however, some serological evidence of the disease in the small, isolated, rural donkey population. -278- U IM I T E D K I N G D O M / G R E A T B R I T A I N I.

Highly pathogenic avian influenza (fowl plague) Fowl plague is a notifiable disease and is controlled by a policy of slaughter and compensation of affected flocks and movement controls of all flocks within a 10-km radius. 3. Newcastle disease Newcastle Disease is a notifiable disease and there is a policy of voluntary vaccination with live lentogenic and inactivated vaccines. Virulent Newcastle Disease is controlled by slaughter and compensation of the affected flocks, and movement controls on all flocks within a 10-km radius. II. LIST B DISEASES Diseases of multiple 1. species Anthrax There was a single outbreak of anthrax during 1995 involving one heifer on a farm on which anthrax had occurred before, situated in an area historically associated with the tannery trade. The affected heifer was fed silage made from the meadow where the previous case occurred. 2. Aujeszky's disease Great Britain remained free of Aujeszky's disease, no cases occurred during 1995. The last recorded outbreak was in October 1989. -279- A programme of blood sampling and testing breeding boars at slaughter continued, together with the screening of pig herds for Aujeszky's disease as part of routine diagnostic investigations carried out by Veterinary Investigation Centres. 3. Rabies Great Britain remained free of rabies. No cases have been recorded outside quarantine since 1970. The policy is to keep rabies out of the country by strict import controls and to have well laid contingency plans to eradicate the disease effectively and swiftly should it ever occur again in Great Britain. Diseases of cattle 4. Bovine brucellosis Great Britain remains Officially Brucellosis Free with no outbreaks reported in 1995. All dairy herds are monitored by monthly Milk Ring Test. There is routine biennial testing of all beef herds and young stock in dairy herds, with special arrangements for dealers, heifer-rearers and herds with intakes of Irish cattle; approximately 1.1 million blood samples were tested during the year. A total of 27,000 abortions and premature calvings were investigated by veterinary staff with negative results in every case. 5. Bovine tuberculosis All herds in Great Britain remain Officially Tuberculosis Free and are subject to tuberculin testing every four years. There has been an overall increase in the incidence of tuberculosis in parts of South West England and South Wales, mainly due to transmission of disease from badgers. Disease in cattle in these areas is detected early by more frequent tuberculin testing. Where badgers are shown to be responsible for disease in cattle, specialist teams of Ministry staff ar used to cage trap them on the affected farms, after which they are humanely destroyed. A trial has continued in some areas using an ELISA test to detect disease in badgers which are trapped, anaesthetised and blood sampled. Positive individuals are destroyed, as are other badgers from positive groups. If this programme is successful, it will form the basis of a new control strategy. Work has continued throughout the year into developing a badger vaccine, alternative tests for cattle (including blood tests) and on understanding the ecology of the badger and the factors affecting spread of disease from wildlife reservoirs. Bovine tuberculosis was confirmed in two wild roe deer in England during the year, and none in farm or park deer. Carcases with suspect lesions are regularly reported and samples submitted for laboratory examination. 6. Enzootic bovine leukosis Under a national testing programme for enzootic bovine leukosis (EBL), all blood samples collected for testing for brucellosis are also tested for EBL. All dairy herds are tested every three months by sampling milk supplies. During the course of the year, infection was detected by these means in 7 herds. In each case, only a single animal was found to be infected. After confirmation of infection, herd restrictions are imposed. There were 17 suspected clinical cases reported during the year. All were investigated and found to be negative. Of the 120 tumour samples submitted routinely from abattoirs for histological investigation, 26 were diagnosed as lymphosarcoma, but tracing revealed no EBL-positive cattle in the herds of origin. Routine post-import testing revealed one seropositive animal in post-import isolation. The animal was slaughtered, and the remaining animals in the group were re-tested with negative results after a further four months' isolation. No reactors were found in routine periodic test in either artificial insemination studs or Cattle Health Scheme herds. -280- 7. Bovine spongiform encephalopathy All cattle suspected of having bovine spongiform encephalopathy (BSE) are slaughtered and compensation is paid to the owners. The probable cause of the epidemic, the feeding of ruminant derived protein containing scrapie/BSE agent to ruminants, was prohibited in July 1988. In 1995, legislation was consolidated and the removal of the brain and eyes from the heads of cattle was prohibited. There was further evidence of the effect of the ban in 1995. The 2 9 . 5 % decline in the number of cases reported in 1994 was followed by a decline of 39.6% in 1995. During the year, a total of 15,453 cases were confirmed, compared with 25,579 in 1994. Some of these would have been reported and slaughtered in 1994. Diseases of sheep and goats 8. Caprine and ovine brucellosis (excluding B. ovis) An on-farm surveillance programme was carried out on 1,555 sheep flocks and 271 goat herds with negative results. In addition, sheep foetuses from 3,449 premises and goat foetuses from 35 premises were tested for B. melitensis with negative results. National freedom as recognised by the EC Commission was thus maintained during 1995. 9. Contagious agalactia National freedom as recognised by the EC Commission is currently being sought. An on-farm surveillance programme was carried out on 2,277 sheep flocks and 318 goat herds in 1995 with negative results. 10. Scrapie Scrapie was made a notifiable disease in January 1993 as part of the implementation of Directive 91/68/EC. Scrapie was confirmed on 116 premises during 1995. Diseases of horses 11. Contagious equine metritis The isolation of the contagious equine metritis organism remains notifiable within Great Britain. Great Britain has been free of the contagious equine metritis organism since September 1990 when a single isolation was recorded in a non-thoroughbred horse; the last case involving a thoroughbred horse was in January 1986. The Common Code of Practice, now also applicable to France, Germany, Ireland and Italy, continues to be followed within Great Britain and the Code is applicable to both the thoroughbred and non-thoroughbred sectors of the Industry. 12. Equine infectious anaemia The last recorded case was in 1976. Diseases of pigs 13. Enterovirus encephalomyelitis Enterovirus encephalomyelitis is notifiable in Great Britain but has never been recorded. Diseases of poultry 14. Salmonellosis Isolations of salmonella are reportable under the Zoonoses Order 1989. Although statutory monitoring of poultry laying flocks is no longer required, monitoring of breeding flocks continues in line with Directive 92/117/EC. During 1995, one layer breeder flock and 14 broiler breeder flocks were found to be infected with S. enteritidis PT4. Two broiler breeder flocks were found to be infected with S. typhimurium. -281 - Diseases 15. offish Viral haemorrhagic septicaemia and infectious haematopoietic necrosis Infectious haematopoietic necrosis (IHN) and viral haemorrhagic septicaemia (VHS) are notifiable under the Diseases of Fish Act 1937 and had never been recorded in Great Britain prior to an outbreak of VHS on a turbot farm on the island of Gigha in 1994. The whole of Great Britain remains an approved zone for IHN and, all but the island of Gigha, an approved zone for VHS. An eradication programme has now been completed on Gigha, but movements of live fish to the remainder of Great Britain continue to be strictly controlled as laid down by Directive 91/67/EC. 16. Spring viraemia of carp Spring viraemia of carp (SVC) was made notifiable in 1976 under an amendment to the Diseases of Fish Act 1937 and strict movement controls are applied to designated sites. In the beginning of 1994 only two sites were designated for SVC and those sites had restrictions lifted in summer 1994 following a clearance testing programme. However, major outbreaks of SVC, linked to imported ornamental fish in 1994 and illegal imports of coarse specimen fish in 1995 led to further outbreaks in 22 and 14 sites, in respective years. Further clearance and disinfection programmes have now limited controls to 21 sites which are all extensive fisheries or ornamental lakes. Diseases of molluscs 17. Bonamiosis and marteiliosis Bonamiosis and marteiliosis are notifiable diseases of shellfish under the Diseases of Fish Act 1937. Marteiliosis has never been recorded in Great Britain, but bonamiosis is found in major stretches of the south and south-east coast of England, where populations of Ostrea edulis, the susceptible species, exist. Diseases of bees There are three notifiable bee diseases for which the Ministry of Agriculture (MAFF) has responsibility. American foulbrood, European foulbrood and varroasis are controlled under the Bee Diseases Control Order 1982, and the Animals and Animal Products (Import and Export) Regulations 1995. Bees Officers are employed under these Regulations to inspect colonies and control disease when detected. The Central Science Laboratory (CSL) employs 10 regional Bee Inspectors full-time and 30 to 35 seasonal Bee Inspectors part-time between April and September. All suspect disease samples are despatched to the National Bee Unit for laboratory diagnosis by Bees Officers (statutory samples) and by beekeepers (voluntary samples). 18. American foulbrood All cases are destroyed by burning. In 1995, 202 infected colonies were detected. 19. European foulbrood Lightly infected cases are treated with oxytetracycline by CSL Bees Officers. Heavily infected cases are destroyed by burning. In 1995, 616 cases of European foulbrood were detected. 20. Varroasis Varroa was detected for the first time in Devon in 1992. There is currently a MAFF movement restriction policy in force. Movement of colonies from areas where varroasis is known to exist to areas apparently free from the disease is prohibited. Beekeepers treat colonies with approved proprietary products. 21. Nosematosis and acariasis of bees Nosematosis and acariasis are not notifiable. They are treated by beekeepers and are considered endemic throughout the United Kingdom. -282- III. OTHER DISEASES Diseases of cattle 1. Warble infestation Warble fly infestation of cattle is a notifiable disease. Voluntary preventive treatment, which is encouraged by publicity campaigns, has been very successful in eradicating the disease. Serological surveys have been carried out each year since 1988 to find the remaining pockets of infestation. When seropositive animals are found all cattle within three km are compulsorily treated. Diseases of sheep 2. Sheep scab Sheep scab was deregulated in 1992, and responsibility for control now rests with the sheep industry. Targeted surveillance programmes have been carried out to assess any changing pattern of disease incidence. Diseases of fish 3. Infectious pancreatic necrosis Infectious pancreatic necrosis is a notifiable disease of salmon and monitoring of salmon farms in Great Britain is undertaken to identify infected sites which are designated and movement controls applied. 4. Renibacteriosis Renibacteriosis (caused by Renibacterium salmoninarum) and also known as bacterial kidney disease was made a notifiable disease under the Diseases of Fish Act 1937. At present, 24 salmonid sites in England and Wales are designated for renibacteriosis and 16 sites in Scotland.

Animal disease control activities APHIS continues to make progress in the brucellosis and tuberculosis control and eradication programmes. A sentinel veterinary practice pilot project has been initiated to determine the prevalence of porcine reproductive and respiratory syndrome in select regions of the country. The Aujeszky's disease five-stage control and eradication programme is progressing. USDA-APHIS-Veterinary Services (VS) is monitoring APHIS programme diseases and other selected diseases through the Veterinary Diagnostic Laboratory Reporting System (VDLRS). VDLRS is a network of 28 State and national veterinary diagnostic laboratories. Aquaculture In response to the growing importance of aquaculture in international commerce industry, State and federal groups met in a coordinated effort to develop harmonized approaches to trade. The aquaculture industry is regulated by various federal and State agencies. APHIS-VS role in aquaculture has been limited to certification of ornamental species for export. Foreign animal disease investigations From October 1994 through September 1995, VS conducted 270 investigations for suspected foreign animal diseases (FAD). These actions are part of the emergency programmes approach to FAD surveillance to insure that an exotic disease does not become established in the United States. Legislation USDA-APHIS had a number of major changes under development in 1995, including a regionalization docket and a docket to establish domestic tuberculosis regulations for cervids. These proposed rules are expected to be published for comment during 1996. The majority of 1995 dockets were in response to changes in the disease status of a country or State. A docket was published which eased restrictions on in-transit movement of pork from parts of Mexico considered low risk for hog cholera. A docket was also published to move a cattle brand from the face to the hip. I. L I S T A DISEASES General overview Diseases present in 1995 Vesicular stomatitis - Virus N.

As of 31 December 1995, all affected States were free of disease. There were 1,162 field investigations with 367 positive premises; all were released from quarantine. Wildlife isolates (New Jersey strains) have historically been made on Ossabaw Island, Georgia, although none were made in 1995. 2. Bluetongue In 1995, slaughter cattle were randomly selected from 18 north-eastern and north-central States. Alaska and Hawaii had only 32 of 8,240 (0.4%) positive samples by the bluetongue competitive ELISA. In deer In 1995, a nationwide survey for bluetongue and epizootic haemorrhagic disease virus (EHDV) in deer has been partially completed. Reports so far indicate a substantial die-off of white-tailed deer (Odocoileus virginianus) in parts of South Dakota, North Dakota, Wyoming and Montana attributed to EHDV serotype 2. Mortality also occurred in central North Carolina due to EHDV-2. Deer losses have also been reported from Alabama, Louisiana and Mississippi. II. LIST B DISEASES Diseases of multiple 1. species Pseudorabies (Aujeszky's disease) Through December 1995, a total of 3,696 pig herds had confirmed pseudorabies. As of 1 January 1996 there were 0 State in stage I, 6 in stage II, 5 in stage Will, 14 in stage III, 1 in stage III/IV, 8 in stage IV, and 18 in stage V (free from the disease: Alaska, Connecticut, Delaware, Idaho, Maine, Mississippi, Montana. North Dakota, New Mexico, Nevada, New York, Oregon, South Carolina, Utah, Virginia, Vermont, Washington and Wyoming). USDA is conducting a cooperative feral swine pilot project on pseudorabies virus and swine brucellosis. Seropositive wild swine were reported from 98 counties in 10 States (Alabama, Arkansas, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina and Texas). The overall seroprevalence rate was 27.7% (4,293 of 15,494 samples). 2. Rabies Raccoon rabies has continued to spread in the north-eastern United States, with the affected area extending from North Carolina in the south to New York in the north. The disease is approaching the -285- Canadian border in New York. The coyote/urban dog strain continues to expand in south Texas after its initial detection in 1988. Oral vaccines are being used in Texas to control the coyote/urban dog strain and the gray fox strain. 3. Paratuberculosis Culture, serology, DNA probes, and histopathology were utilized in the VDLRS voluntary monitoring programmes. Thirty States reported positive tests in bovine, caprine, ovine, bison and cervidae during 1995. Thirty-one States reported positive results during 1994. Diseases of cattle 4. Bovine brucellosis Thirty-four States, Puerto Rico and the US Virgin Islands are "Free", and 16 States are "Class A". Brucellosis in bison and elk is confined to the Greater Yellowstone National Park and the Grand Teton National Park in Wyoming. 5. Bovine tuberculosis Forty-three States and the US Virgin Islands are "Accredited Free", one State had its free status suspended after confirming Mycobacterium bovis in one recently purchased animal, and six States and Puerto Rico are "Modified Accredited Free". Of the nine infected cattle herds, two were reported in 1995 and the other six were carried over from 1994. The one infected herd in 1995 contained one infected bovine. One case in a white-tailed deer in Michigan was reported in November 1994. A hunter kill survey in the fall of 1995 revealed an additional 15 cases. At present, only one focus of infection is known. There has been no spread to domestic animals. 6. Enzootic bovine leukosis The AGID test is being used to screen and monitor beef and dairy cattle in several States. Thirty-four States reported positive serology through the VDLRS during 1995. Twenty-nine States reported positive results during 1994. The monitoring programme is being conducted as a voluntary exercise in cooperation with State diagnostic laboratories. 7. Bovine spongiform encephalopathy From 1986 through December 1995. a total of 2.660 brain samples were submitted for examination to the National Veterinary Services Laboratory (NVSL) and other laboratories. All samples were negative for bovine spongiform encephalopathy (BSE). The United States remains free from BSE. There are presently 116 cattle under permanent surveillance that were imported between 1981 and 1989 from BSE-affected countries. Diseases of sheep and goats 8. Scrapie As of 9 February' 1996, a total of 197 flocks are participating in the scrapie certification programme. Sixty-seven flocks are confirmed with scrapie. Diseases of horses 9. Equine encephalomyelitis (Eastern and Western) From January through October 1995, there were 35 positive horses for Eastern equine encephalomyelitis out of 181 horses tested by the NVSL. There were no cases of Western equine encephalomyelitis confirmed in horses by the NVSL. -286- 10. Equine infectious anaemia From October 1994 through September 1995, there were 1,804 (0.16%) horses positive by the AGID test out of 1,116.396 horses tested by the US veterinary diagnostic laboratories. Diseases of pigs 11. Porcine brucellosis Forty-three States are "Validated Free" (stage III), and 7 States are in stage II (Alabama, Arkansas, Florida. Georgia, Louisiana, Oklahoma, South Carolina and Texas). 12. Porcine reproductive and respiratory syndrome Thirty-one States reported positive results by virus isolation or indirect fluorescent antibody serology through the VDLRS voluntary monitoring programmes during 1995. Thirty States reported positive results during 1994. Diseases of poultry 13. Duck virus enteritis Duck virus enteritis was reported in wild waterfowl in New York, Virginia, Pennsylvania, Texas and California in 1995. 14. Mycoplasmosis (A/, sallisepticum) Commercial broiler and laying flocks are vaccinated or treated in event of clinical signs, while all breeding flocks depopulate. Conjunctivitis in house finches caused by Mycoplasma gallisepticum was first reported in February 1994 and has spread through the eastern United States. In pilot studies, the M. gallisepticum isolate from finches caused disease in chickens and turkeys experimentally, but there have been no reports of infection in commercial poultry. III. OTHER DISEASES 1. Chronic wasting disease Chronic wasting disease is endemic in the Fort Collins, Colorado, and Laramie, Wyoming area. 2.

En el período considerado no se registraron brotes de ninguna enfermedad de la Lista A, siendo todas ellas denunciables existiendo medidas de protección a la importación de animales, productos y subproductos. El país implemento las medidas de protección necesarias para asegurar el mantenimiento de la condición sanitaria alcanzada, éstas comenzaron a aplicarse en 1994 y concluyen en 1995 con la puesta en funcionamiento de las "barreras fito-zoo-sanitarias" destinadas al control de la internación informal de animales, productos, subproductos y derivados de origen animal o vegetal, que acompañan a turistas y viajeros. Dicho control se efectúa en puertos, aeropuertos así como en los pasos de frontera habilitados, ello supone 23 puestos de control atendidos por 57 profesionales y 124 técnicos. Durante el primer año de funcionamiento se decomisaron 30.479 productos de origen animal y vegetal. Se atendieron 33 sospechas de la enfermedad, desestimadas desde el punto de vista clínico, epidemiológico, anatomopatológico y de laboratorio. Importa destacar que en los protocolos se determina la hora de aviso del productor y hora de atención del servicio para medir el tiempo de reacción que se considera aceptable en la mayoría de los casos, siendo promedialmente de tres a cuatro horas. Las medidads sanitarias a aplicar frente a la reaparición de la enfermedad alcanza no sólo a bovinos, ovinos y suinos, sino también a caprinos (ley N° 16.462 del 11 de enero de 1994, art. 58°) y a toda otra especie afectada (facultad otorgada por el art. 2° de la ley 3.606 del 13 de abril de 1910). El aviso o notificación obligatoria de la fiebre aftosa abarca a todos los tipos o subtipos o variantes del virus causante de la enfermedad y por lo tanto queda incluida en la comunicación obligatoria la fiebre aftosa producida por los virus SAT 1, SAT 2, SAT 3 y Asia 1.

En 1995 se procesaron 3.069 sueros bovinos, siendo 55 positivos para brucelosis al Rosa de Bengala, y de éstos 27 positivos a las pruebas confirmatorias. Se estima que las tuberculinizaciones efectuadas fueron aproximadamente unas 240.000 y los animales positivos alrededor de 20. 5. Encefalopatía espongiforme bovina Cabe destacar que Uruguay está libre de prurigo lumbar y de encefalopatía espongiforme bovina, pero que se cumple con la normativa del Código Zoosanitario Internacional a los efectos de poder ser reconocido país libre. -289- Con la finalidad de optimizar este procedimiento, el mismo se hizo extensivo a todas las especies animales pudiendo así monitorearse todas las enfermedades que afectan el sistema nervioso central tales como rabia, encefalomielitis equina, etc. Enfermedades 6. de ovinos y caprinos Epididimitis ovina (Brucella ovis) Se investigaron 40 sueros ovinos para Brucella ovis, resultando todos negativos. 7.

Enfermedades 8. melitensis 891 sueros ovinos para la exportación, resultando todos de porcinos Brucelosis porcina La aparición de casos humanos de brucelosis de origen suino en establecimientos de faena llevó al servicio a implementar procedimientos de vigilancia epidemiológica a los efectos de controlar dicha epidemia. Así, durante 1995 se detectaron 48 predios infectados, los que fueron saneados en base a la eliminación de las poblaciones. La detección semanal de positivos disminuyó significativamente pero las medidas de vigilancia continuarán hasta la erradicación de la enfermedad. Enfermedades 9. de aves de corral Tifosis aviar (Salmonella sallinarum) y pulorosis (S. pullorum) Se controlan todas las incubadurías y plantas reproductoras del país por prueba de aglutinación. Los animales positivos se sacrifican. Enfermedades de abejas De 3.000 muestras procesadas, el 1% aproximadamente se detecta como acariosis, 2 0 % de nosemosis, y una frecuencia elevada de varroasis. Esta última enfermedad presenta características benignas no evidenciándose importantes pérdidas económicas. -290- V A N U A T U I. INTRODUCTION Veterinary manpower In 1995, the transition in the supply of veterinary officers away from British aid-supported personnel to officers contracted by the Government of Vanuatu from M A F Quality Management, New Zealand, commenced for a three-year period. Development of Veterinary Sen'ices activities Two donor-assisted projects aimed at improvement in animal health reporting and control came fully on-stream in 1995 as follows: 1. Animal health surveillance and monitoring project This project, managed by MAF Quality Management, New Zealand, with support from the European Union commenced in October 1994. The aim of the programme is to install a system which will allow Vanuatu to gain international recognition for its animal disease free status. In 1995 the project completed the following elements of the programme: • A national computerised database to support animal disease surveillance and disease control operations, analyses and reporting was developed, put into operation and staff trained to run it. All livestock owning farmers will be registered in this database and all disease incidents, diagnoses and findings will be recorded in an easily retrievable format. • Laboratory facilities within the Department of Livestock (including training of staff) were upgraded to enable initial bacteriological and parasitological examinations to be carried out locally. Links were developed with the Central Animal Health Laboratory, New Zealand, and other appropriate international diagnostic centres for analyses of exotic diseases (including OIE List A diseases) should they be suspected to occur within Vanuatu. • A documented quality system was developed (Systems Vanuatu), based on the relevant elements of the ISO 9000 series of standard. The Systems Vanuatu will: • - enable efficient use of staff and equipment; - make sure that programmes continue to operate properly; - help staff to understand the technology and systems used in the department; - enable systems and procedures to be audited or checked by people outside of the department; - demonstrate to the Minister of Agriculture and to industry that the system is operating smoothly; - provide opportunities to continually improve systems and procedures. The field testing programme for bovine brucellosis and tuberculosis was upgraded and expanded with the development of written rules and standards and expansion of testing into areas not previously fully tested. -291 - 2. Vanuatu agricultural security project This five-year project commenced in November 1994 with financial support from the Government of New Zealand. The objectives of this project are to upgrade quarantine systems for all livestock and crop imports and exports for Vanuatu. In 1995 improved infrastructural installations were made for incineration and fumigation services and initial studies commenced on improved systems, financial sustainability, management and extension programmes. Proposed developments In 1995 a project was developed with the objectives of carrying out a national survey of honey bee diseases in Vanuatu, training staff in their diagnosis and formulating quarantine protocols to protect the country from exotic diseases. It is hoped to commence this project using external expert consultants in early 1996. Legislation New regulations were drafted under the 1992 Animal Disease (Control) Act. They allow for movement restrictions for animals and animal products within Vanuatu and specify controlled and notifiable diseases. These regulations should come into force in 1996. I. LIST A DISEASES There was no change in the situation regarding List A diseases in Vanuatu in 1995. No List A diseases have ever been reported. II. LIST B DISEASES The situation regarding List B diseases remained the same as in 1994. No cases of bovine brucellosis or tuberculosis were detected in 1995 despite expansion of the field testing programme. -292- Z A Ï R E INTRODUCTION Malgré la situation difficile sur le plan économico-social que connaît le pays, l'année 1995 n'a pas connu une menace quelconque sur l'état de la santé animale. L'intervention des Services vétérinaires au cours de l'année 1995 sur la santé animale n'a pas été manifeste. Cela s'explique par la carence des intrants, le manque de logistique et surtout la non motivation du personnel technique. Le Zaïre compte parmi les pays d'Afrique qui ne sont pas encore parvenus à organiser le secteur de l'élevage, malgré les énormes potentialités qu'il possède pour le développement des élevages. Le manque de moyens de communication fait que beaucoup de situations sanitaires ne sont pas déclarées à temps. Bien que connues, ces situations ne connaissent que peu d'interventions des Services vétérinaires confrontés aux nombreux problèmes d'ordre logistique. En dehors des campagnes de vaccination anti-rabique organisées dans certaines régions du pays (Kasaï Occidental, Bas-Zaïre), les activités de routine ont porté sur le bétail situé dans les zones de hautes concentrations animales dans l'est du pays. Des campagnes prophylactiques contre les maladies parasitaires ont été prévues et réalisées. I.

Maladies absentes en 1995 (entre parenthèses Commentaires Fev 0 d'information Clavelée et variole caprine présentes Péripneumonie contagieuse bovine Déclarée en début d'année 1992 dans les zones d'Aru et Mahagi, district d'Ituri, région du Haut-Zaïre, la péripneumonie contagieuse bovine a connu une période d'accalmie en 1995 grâce à la vaccination entreprise en 1993 et au renforcement des mesures de police sanitaire. Il se pose encore le problème de l'exécution des campagnes de rappel pour consolider la première vaccination dont les réalisations ont atteint 89,4 %. Le manque de moyens financiers et logistiques est à 1994 1993 1992 1994 -293- l'origine de ce retard dans l'organisation desdites campagnes. Il y a lieu de craindre un rebondissement de la situation dans les prochains mois. 2. Dermatose nodulaire contagieuse Le bétail de la région du Nord-Kivu a été fortement atteint par cette maladie en 1993. Sa progression fut stoppée grâce à la campagne de vaccination organisée la même année avec du vaccin fourni par la FAO. Bien que maîtrisée au Nord-Kivu, des cas sporadiques sont constatés dans la région du Haut-Zaïre, voisine du Nord-Kivu, et dans des troupeaux venus d'un pays voisin. 3. Peste porcine africaine La peste porcine africaine est un frein au développement des élevages porcins, surtout dans les parties sud et ouest du Zaïre frontalières avec l'Angola. Les élevages paysans connaissent chaque année des pertes énormes. Des mesures de police sanitaire sont prises, mais elles sont quelquefois négligées. 4. Maladie de Newcastle A l'état endémique dans le pays, la maladie de Newcastle fait des ravages, surtout pendant la saison sèche qui va de mai à octobre. La vaccination est pratiquée, mais d'une façon sélective car les éleveurs traditionnels n'ont pas la possibilité d'obtenir facilement du vaccin. En outre, aucun programme de lutte de grande envergure n'est envisagé, bien que les pertes soient énormes, allant jusqu'à 60 % des effectifs. IL MALADIES DE LA LISTE B Maladies communes à plusieurs 1. espèces Fièvre charbonneuse La fièvre charbonneuse sévit à l'état endémique, mais les pertes ne sont pas très importantes car des campagnes de vaccination prophylactique sont organisées chaque année. 2. Rage La rage est un fléau qui préoccupe les Services vétérinaires. L'année 1995 a connu des déclarations nombreuses à travers le pays, surtout dans les centres urbains où plusieurs cas de morsures ont été enregistrés, entraînant la mort d'hommes. Des campagnes de vaccination ont été lancées à travers le pays, et les mesures de police sanitaire ainsi que l'abattage des chiens errants ont été renforcés. Maladies des bovins 3. Trypanosomose L'élevage du bétail trypanotolérant permet aux éleveurs d'éviter cette affection. Toutefois, là où sont élevées d'autres races, une chimiothérapie est appliquée périodiquement. Eu égard à la répartition des espèces trypanosensibles, qui constituent plus ou moins 65 % du cheptel, l'utilisation de produits tels que le Berenil ou le Trypamidium a fait ses preuves dans la protection du bétail. Maladies des volailles Les maladies aviaires telles que la bronchite infectieuse, la typhose (Salmonella gallinarum), la bursite infectieuse (maladie de Gumboro) et la pullorose (S. pullorum) ont fait l'objet de vaccinations dans les élevages organisés. -294- Z A M B I A LIST A DISEASES Diseases present in 1995 Foot and mouth disease - Virus SAT 3 Lumpy skin disease African swine fever Newcastle disease Diseases never Total 1994 0 -K.

These cases were in isolated transhumant herds. As a result, biannual vaccination with a trivalent vaccine has been instituted in the affected areas and areas at risk. 0000 12-94 12-94 12-94 -295- Z I M B A B W E I.
