Isolation of Mycobacterium bovis from the prepuce of a herd bull.
A tuberculous lesion was found in the prepuce of a 5-year-old tuberculin-positive herd bull at necropsy. Microscopic examination revealed granulomas with Langhans'-type giant cells; Mycobacterium bovis was isolated. The bull had been used in artificial insemination procedures and for natural breeding.
