A bovine adenovirus type 3: isolation, characterization, and experimental infection in calves

A virus was isolated from a group of feedlot cattle with acute respiratory disease that was characterized by physicochemical methods as an adenovirus and identified serologically as a bovine adenovirus type 3. Intratracheal inoculation of three 4 month old colostrum deprived calves resulted in pyrexia, hyperpnea, dyspnea, anorexia and in one animal a mild diarrhea.
