Diabetes mellitus in cattle infected with bovine viral diarrhea mucosal disease virus

Abstract

Four Japanese black cattle and four Holstein-Friesian cows were diagnosed with diabetes mellitus. Based on intravenous glucose tolerance tests, all these animals were believed to be insulin-dependent diabetics. Moreover, bovine viral diarrhea-mucosal disease (BVD-MD) virus was isolated and mucosal lesions and diarrhea were recognized in all cases. There was no genetic relation among the affected cattle. The breeding places of these cattle were different to each other. Therefore, it is suggested that BVD-MD virus induced the diabetes mellitus.
