title: Persistent bovine virus diarrhoea virus infection in a bull.
abstract: Investigation of a sight defect in a pedigree bull, born as a result of artificial insemination and ovum transplantation, led to the finding that the animal was persistently infected with bovine virus diarrhoea virus. Virus was cultured from blood and from nasal and ocular swabs and was present in semen in high titre. At necropsy, virus was cultured from a wide range of tissues. The pathological findings are described and discussed as are the potential hazards of such infections.
