Lehmkuhl, H. D. | Cutlip, R. C. | DeBey, B. M.
Virus isolated from the lung, liver, kidney, and small intestine of a 3-month-old Holstein heifer with a clinical history of pneumonia and lesions in multiple organs was identified as an adenovirus on the basis of morphological and physicochemical characteristics. The adenovirus was determined to be a serotype 10 bovine adenovirus and represents the first reported isolation of this serotype in the United States. Inoculation of calves with this isolate resulted in mild to moderate clinical response consisting of fever, inappetence, increased respiratory rate, cough, and listlessness. Gross lesions were minimal in the respiratory tract and consisted of fibrin in the airways and small areas of consolidation in the cranial lobes of the lung. Mucofibrinous foci were present on the mucosa of the upper small intestine.
