Otitis interna was diagnosed in five 9-to-21-day-old turkey poults with clinical signs of paralysis, opisthotonus, torticollis, blindness, and increased mortality. Gross and microscopic lesions in the poults included omphalitis, typhlitis, hepatitis, meningoencephalitis, ophthalmitis, neuritis and ganglionitis of the vestibulocochlear nerve, and otitis interna. Salmonella enterica arizonae was isolated from the brains, eyes, intestines, yolk sacs, and livers of poults. Birds with otitis interna also had meningoencephalitis. It is most likely that the S. enterica arizonae infection spread from the brain to the internal ears through the vestibulocochlear nerve. This is the first documentation of otitis interna caused by bacteria in an avian species.
在5只9至21日龄的火鸡雏中诊断出内耳炎，这些雏鸡有麻痹、角弓反张、斜颈、失明和死亡率增加等临床症状。雏鸡的大体和微观病变包括脐炎、盲肠炎、肝炎、脑膜脑炎、眼炎、前庭蜗神经神经炎和神经节炎以及内耳炎。从雏鸡的脑、眼、肠、卵黄囊和肝脏中分离出亚利桑那沙门氏菌。患有内耳炎的鸟类也有脑膜脑炎。很可能亚利桑那沙门氏菌感染是通过前庭蜗神经从脑传播到内耳的。这是禽类中由细菌引起内耳炎的首次记录。
