Tuberculosis in fennec foxes.

Fennec foxes (Fennecus zerda) in 2 zoos were found on necropsy to have lesions typical of those found in canine tuberculosis. Histologic examination revealed numerous acid-fast bacilli in lesions of liver, portal lymph node, spleen, kidney, and lung. Mycobacterium bovis isolated from tissues was identified by biochemical methods and by pathogenicity tests in guinea pigs and rabbits.
