A 3-yr-old Ameraucana hen was received for postmortem examination following a 1-day history of lethargy and death. Gross lesions observed during necropsy were limited to pulmonary congestion and a small clump of egg yolk material in the oviductal lumen. On histopathology, there was a necrotizing salpingitis of the infundibular and isthmus mucosa with amphophilic, intranuclear inclusion bodies in superficial epithelial cells. Transmission electron microscopy identified the intranuclear inclusions as aggregates of adenovirus virions. Fowl adenovirus (FAdV) type A was identified with PCR and sequencing. Although the cause of death was not determined in this case, this is the first report of FAdV type A–associated salpingitis in a hen.
