A case of mycobacteriosis in a collection of canaries (Serinus canarius) is described. The affected birds showed nonspecific clinical signs and macroscopic lesions (slight splenomegaly). Histologic lesions found in liver, spleen, lungs, and kidneys consisted of noncaseous nodules containing accumulations of large macrophages that showed a highly vacuolated cytoplasm in which numerous acid-fast organisms were detected. Attempts to isolate and culture the organisms using Läwenstein-Jensen and Coletsos media proved unsuccessful. Microorganisms belonging to the species Mycobacterium genavense were identified by means of polymerase chain reaction techniques in hepatic tissue from both birds. This finding confirms the existence of fastidiously growing mycobacterial infections, other than Mycobacterium avium, in birds
