Properties of the bovine viral diarrhoea virus replicase in extracts of infected MDBK cells

, 2000
An assay for the bovine viral diarrhoea virus (BVDV) replicase was developed using extracts from BVDV-infected cells. The replicase activity was maximal approximately 8 h post-infection as measured by the generation of a genomic length radiolabelled RNA.

Field Study: Exposure to Bovine Viral Diarrhea Virus Pre-weaning Mitigates the Effect of Constant BVDV PI Exposure During the Early Feeding Period

, 2010
Bovine viral diarrhea virus (BVDV) is a major pathogen involved in the bovine respiratory disease complex (BRD). Immunosuppression induced by BVDV is thought to contribute to BRD, exacerbating secondary bacterial and viral pneumonias. Calves persistently

A Review of the relationship between persistent infection of cattle with bovine viral diarrhea virus and feedlot morbidity and gain

, 2003
Bovine viral diarrhoea is an infectious viral disease of cattle. Persistently infected cattle result from in-utero infection of calves with the bovine viral diarrhoea virus during critical stages of gestation, and affected calves become lifetime carriers
