Cerebrospinal nematodiasis and visceral larva migrans were diagnosed in an Australian (Latham's) brush turkey (Alectura lathami) that died at the Indianapolis Zoo following a progressive neurologic disease. Histologically, multifocal areas of malacia, necrosis, and inflammation were seen in sections of cerebrum, cerebellum, and midbrain; lesions were most severe in the cerebellum. A large granuloma in a lung contained cross sections of a large ascarid larva identified as Baylisascaris. The CNS lesions were typical of larval migration, as documented in other avian species. An epizootiologic investigation indicated that Baylisascaris procyonis was the etiologic agent and that the bird had acquired the parasite through contact with fecal contamination from wild raccoons at the St Louis Zoo, where the bird had been raised.
一只在印第安纳波利斯动物园因进行性神经疾病死亡的澳大利亚（拉瑟姆氏）刷尾火鸡被诊断患有脑脊髓线虫病和内脏幼虫移行症。组织学检查显示，在大脑、小脑和中脑切片中可见多灶性软化、坏死和炎症区域；小脑病变最为严重。肺内一个大肉芽肿包含一条被鉴定为贝利斯蛔虫的大型蛔虫幼虫的横切面。中枢神经系统病变是幼虫移行的典型表现，在其他鸟类中也有记载。一项流行病学调查表明，病因是浣熊贝利斯蛔虫，这只鸟是在圣路易斯动物园饲养期间通过接触野生浣熊的粪便污染而感染了这种寄生虫。
