Lesions of Mycobacterium avium spp. hominissuis Infection Resembling M. bovis Lesions in a Wild Mule Deer, Canada

Abstract

We used molecular analyses to confirm Mycobacterium avium spp. hominissuis infection in lung granulomas and pyogranulomas in the tracheobronchial lymph node in a wild mule deer in Banff, Canada. These lesions are similar to those found in M. bovis–infected animals, emphasizing the critical need for disease surveillance in wildlife populations.
