两只小牛和一只饲养场阉牛与系统性牛腺病毒感染有出血和坏死性病变局限于消化道。在一头小牛有严重的，多灶性，坏死性，出血性瘤胃炎，乳腺炎，皱胃炎，肠炎和结肠炎。小肠病变以Peyer斑块为主。多灶性坏死性皱胃炎是另一只小腿的主要变化。在肿胀的血管内皮细胞中常见典型的牛腺病毒大的亲两性核内包涵体。从前一头小牛身上分离出牛腺病毒。牛有弥漫性出血性小肠结肠炎，肠固有层血管内皮细胞内有大量BAV包涵体。对6只临床感染的接触动物的急性和恢复期样本进行的牛腺病毒3型血清中和试验显示，其中2只血清中病毒含量升高4倍。
Two calves and a feedlot steer with systemic bovine adenovirus infection had hemorrhagic and necrotizing lesions confined to the digestive tract. In one calf there was severe, multifocal, necrotizing, hemorrhagic rumenitis, omasitis, abomasitis, enteritis and colitis. Small intestinal lesions were predominantly in Peyer's patches. Multifocal necrotizing abomasitis was the principal change in the other calf. Large amphophilic intranuclear inclusions typical of bovine adenovirus were common in swollen vascular endothelial cells. Bovine adenovirus was isolated from the former calf. The steer had diffuse hemorrhagic enterocolitis and large numbers of BAV inclusions in vascular endothelial cells of the intestinal lamina propria. Serum-neutralization tests to bovine adenovirus type 3 on acute and convalescent samples from six clinically affected in-contact animals revealed fourfold elevations in two.
