Tuberculosis in greater kudu

Four greater kudu (Tragelaphus strepsiceros) died while maintained in captivity at a zoo. Necropsy revealed tuberculous lesions in the lungs, spleen, and thoracic lymph nodes. Histopathologic findings included granulomas with Langhans' giant cells, necrosis, and mineralization. Acid-fast organisms isolated from tissues of each kudu were identified as Mycobacterium bovis.
