Abstract
Sporadic sudden deaths in adult white-tailed deer occurred from November 1997 through August 1998 on an Iowa game farm. Three of the 4 deer necropsied had severe pulmonary edema, widespread mild lymphocytic vasculitis, and amphophilic intranuclear inclusion bodies in scattered endothelial cells in blood vessels in the lung and abdominal viscera. Immunohistochemistry with bovine adenovirus 5 antisera and transmission electron microscopy demonstrated adenoviral antigen and nucleocapsids, respectively, within endothelial cells. Adenovirus was isolated in cell culture from 1 of the affected deer. The isolate was neutralized by California black-tailed deer adenovirus antiserum. These findings indicate that adenovirus should be considered in the differential diagnosis of both black-tailed and white-tailed deer with pulmonary edema and/or hemorrhagic enteropathy.
