title: Disseminated tuberculosis caused by Mycobacterium avium in a cat.
abstract: A 5-year-old neutered male Siamese cat was examined by a veterinarian because of a recent decrease in appetite and a large lymph node in the left mandibular area. Clinical findings included fever, icterus, leukopenia, and progressive anemia. Despite various treatments, the cat died approximately 3 weeks after initial examination. The main necropsy findings included necrotizing and granulomatous lymphadenitis of the left mandibular lymph node, multifocal necrotizing hepatitis, and interstitial pneumonia. Acid-fast bacilli were detected in lesions of the mandibular lymph node, liver, lung, spleen, and bone marrow. Mycobacterium avium was isolated from the liver. Avian tuberculosis in cats has been reported rarely.
