Distribution of Lesions in Red and Fallow Deer Naturally Infected with Mycobacterium bovis

摘要: Wild deer have an important role in the epidemiology of bovine tuberculosis (bTB). The aims this study were (1) to compare pattern lesions present wild red (Cervus elaphus) and fallow (Dama dama) that naturally infected with Mycobacterium bovis, (2) use information develop a sampling strategy for isolation M. bovis from lymphoid tissues head these animals. Culture demonstrated 28 95 22 100 sampled bovis. Approximately 30% each population had no gross lesions. Fallow significantly more likely thoracic than deer. Lesions observed retropharyngeal lymph nodes 64% culture-positive 43% culture positive One third deer, but none well-encapsulated abscess There microscopical differences Bacteriological both tonsil increased rate by 22% over alone species. These findings indicate investigation bTB-compatible should include examination medial retropharyngeal, left tracheobronchial, mediastinal, mesenteric ileocaecal nodes. Sampling bacteriological be protocols may prove useful bTB surveillance control regions where contribute circulation
