Up to 12% mortality occurred in goslings between 4 and 11 days of age in two sequential hatches from a single breeder flock. Respiratory signs were noted before the birds died. The most consistent necropsy finding was a white opaque plug of fibrin and cellular debris in the trachea. The tracheal epithelium was hyperplastic and metaplastic with intranuclear inclusion bodies present in superficial cells. An adenovirus was isolated in both chicken and goose embryo liver cells.
来自同一繁殖鸡群的两批相继孵化的雏鹅中，4至11日龄的雏鹅死亡率高达12%。这些雏鹅在死亡前出现了呼吸道症状。最常见的尸检发现是气管中有一个白色不透明的纤维蛋白和细胞碎片栓子。气管上皮增生并化生，表层细胞出现核内包涵体。在鸡胚和鹅胚肝细胞中均分离出一种腺病毒。
