title: Mycobacterium avium subsp. paratuberculosis infection in an addax (Addax nasomaculatus).
abstract: Mycobacterium avium subsp. paratuberculosis was cultured from a single fecal sample collected from a 10-yr-old, captive-bred male addax (Addax nasomaculatus). Attempts to confirm infection with additional fecal cultures, serology, semen culture, and tissue biopsy were unsuccessful. There were no gross lesions on necropsy. On histopathology there were neither acid-fast organisms nor microscopic changes suggestive of active or clinical Johne's disease. Mycobacterium avium subsp. paratuberculosis was isolated from four organ tissues: ileum, jejunum, colon, and mesenteric lymph node.
