Two imported male hooded mergansers (Lophodytes cucullatus) were introduced into a zoological aviary in Japan, and one of them died 10 mo later. Postmortem revealed numerous white yellowish nodules of various sizes in the liver. Two large nodules were also observed below the right lung and on the top of the left kidney. Histopathologically, a large number of tubercles with acid-fast bacilli were seen in the liver. The amyloid was deposited in the connective tissue of the tubercles. Bacteriologically, Mycobacterium avium serovar 1 was isolated from the liver.
两只进口的雄性 Hooded Mergansers（冠小潜鸭，学名：Lophodytes cucullatus）被引入日本的一个动物园鸟类饲养场，其中一只在 10 个月后死亡。尸检发现肝脏中有许多大小各异的白色黄色结节。在右肺下方和左肾顶部也观察到两个大结节。组织病理学检查显示，肝脏中有大量带有抗酸杆菌的结核结节。淀粉样物质沉积在结核结节的结缔组织中。细菌学检查从肝脏中分离出鸟分枝杆菌血清型 1。
