Incidence of bovine tuberculosis in wild and domestic animals other than cattle in six Central European countries during 1990-1999

The study was undertaken in Croatia, Czech Republic, Hungary, Poland Slovakia and Slovenia laying between Baltic and Adriatic seas on 610 402 km2. Mycobacterium bovis infection was diagnosed in 70 animals belonging to 17 species other than cattle. The set of wild animals comprised 12 European bison (Bison bonasus), one red deer (cervus elaphus), five wild boars (Sus scrofa), and one European wild goat (Capra aegagrus) bred in game park. Further positive animals included two farmer red deer (Cervus elaphus) and one bactrian camel (Camelus ferus) owned by circus. The infection was also demonstrated in 18 domestic animals belonging to 3 species living on farms where bovine tuberculosis was diagnosed in cattle. This set included 12 domestic pigs (Sus scrofaf. domestica), two domestic sheep (Ovis ammon f. aries), and four dogs (Canis lupus f. familiaris). The set of animals bred in zoological gardens consisted of 30 animals belonging to 9 species as follows: three bison (Bison bison), four tapir (Tapirus terrestis), one cassowary (Casuarius casuarius - isolate identified by the biological assay in guinea pigs only, eight reticulated giraffes (Giraffa camerloparadlis reticulata, one puma (Puma cancolor) and one Vietnamese pot-beliiied pig (Sus bucculentus). Although, considering the population sizes, absolute numbers of the infected individuals are rather low, wild animals or such animals bred in captivity should be regarded as possible reservoirs of the causative agent of bovine tuberculosis. Tests for bovine tuberculosis are therefore necessary before transportation of all wild animals. Any lesion arousing suspicion of tuberculosis found on necropsy of wild animals must be laboratory examined for the presence of mycobacteria.
