Paratuberculosis in Mouflon (Ovis musimon)

摘要

Mycobacterium avium subsp. paratuberculosis (Map) is the etiologic agent of a severe gastroenteritis in ruminants. We observed injuries compatible with paratuberculosis in mouflon. Morphology, histopathology, isolation, biochemical typification of strains and the study by molecular biology, are described for the first time in Argentina. The objective was to determine the presence of Map from wildlife species which may open up the possibility of wildlife to domestic ruminant transmission. The samples came from one animal of the province of Buenos Aires, Argentina. Haematoxylin-and-eosinstained sections of the gross intestine showed hyperplasia in corion and submucosa with diffuse infiltration of epithelioid cells.
