Effects of exposure to Bovine viral diarrhoea virus 1 on risk of bovine respiratory disease in Australian feedlot cattle

The effects of bovine viral diarrhoea virus on cattle reproduction in relation to disease control.

Bovine viral diarrhoea virus (BVDV) is a major reproductive pathogen in cattle. Infection of the bull can lead to a fall in semen quality and the isolation of infectious virus in the ejaculate, while infection in the cow leads to poor conception rates, abortions and congenital defects. BVDV also reduces the animal's resistance to other respiratory and enteric pathogens. The prevalence of BVDV i...

The occurrence of bovine virus diarrhoea/muscosal disease in Iran

Persistent bovine viral diarrhea virus (BVDV) infection in cattle herds

Bovine viral diarrhea virus (BVDV) is a significant pathogen associated with gastrointestinal, respiratory, and reproductive diseases of cattle worldwide. It causes continuous economic losses to the cattle industry primarily due to decreased reproductive performance. The ability of virus to cross the placenta during early pregnancy can result in the birth of persistently infected (PI) calves. P...

The diagnosis of bovine virus diarrhoea-mucosal disease in cattle.

Laboratory diagnostic procedures for bovine virus diarrhoea and mucosal disease are reviewed. For serology, emphasis is placed on the virus neutralisation test and enzyme immunoassays. The techniques and the pitfalls which may be encountered in culture procedures for isolation of the virus are described, with special reference to the use of immunofluorescence and immunoperoxidase methods for th...
