[Case reports of hemorrhagic diathesis in calves with bovine diarrhea virus infection].

Clinical and pathological findings in six veal calves suffering from haemorrhagic diathesis are reported. Further pathological and virological results were highly suggestive of mucosal disease (BVD). No virus isolation or classification was possible. The post mortem results indicated that the virus might have been cytopathogenic. The cases are discussed and compared with similar field and experimental publications dealing with thrombocytopenia in veal calves in the USA. These are the first reports of cases published in Germany.
