Among 4 European bisons hunted in 1997 in the Bieszczady region, in one animal (male, 8 years old) pathological lesions in the retropharyngeal lymph nodes were found and Mycobacterium bovis strain was isolated. This is the second case of tuberculosis in the same herd. Some results of investigations on tuberculosis of farmed and free living bisons in Canada and USA were discussed.
