Thirty-five birds that died with naturally acquired psittacine beak and feather disease (PBFD) were necropsied to identify extracutaneous viral inclusions. Inclusions were found in various tissue sections from 34 of 35 birds. By immunoperoxidase staining, intranuclear and intracytoplasmic inclusion bodies were shown to contain PBFD viral antigen. Inclusion-bearing lesions were widely disseminated but often closely associated with the alimentary tract. Lesions within the palate, esophagus, crop, intestine, bursa of Fabricius, and liver probably serve as sources for viral shedding into the feces.
对35只死于自然感染鹦鹉喙羽病（PBFD）的鸟类进行尸检，以确定皮肤外病毒包涵体。在35只鸟中的34只的各种组织切片中发现了包涵体。通过免疫过氧化物酶染色，显示核内和胞质内包涵体含有PBFD病毒抗原。含包涵体的病变广泛分布，但通常与消化道密切相关。腭、食管、嗉囊、肠道、法氏囊和肝脏内的病变可能是病毒排入粪便的来源。
