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 Löwenstein-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.
描述了一例金丝雀（Serinus canarius）群体中的分枝杆菌病病例。患病鸟类表现出非特异性临床症状和宏观病变（轻度脾肿大）。在肝脏、脾脏、肺和肾脏中发现的组织学病变为由非干酪样结节组成，其中含有大量巨噬细胞聚集，这些巨噬细胞的细胞质高度空泡化，在其中检测到大量抗酸菌。使用罗氏培养基和科莱索斯培养基分离和培养这些微生物的尝试均未成功。通过聚合酶链反应技术在两只鸟的肝脏组织中鉴定出属于日内瓦分枝杆菌的微生物。这一发现证实了鸟类中除鸟分枝杆菌外还存在生长缓慢的分枝杆菌感染。
