Abstract

Avian tuberculosis is an avian disease of worldwide importance. It is typically caused by serovars 1, 2 and 3 of Mycobacterium avium subsp. avium. This paper describes spontaneous, subclinical tuberculosis in a 5-year-old male Muscovy duck. Necropsy revealed a characteristic distribution pattern of granulomatous lesions involving the liver and spleen. Histopathological analysis confirmed the formation of tubercles containing a large number of giant and epitheloid cells, while PCR analysis (according to insertion sequence IS901) and an agglutination test detected M. avium serovar 2 as the causative agent of this condition.
