Occurrence and phylogenetic analysis of bovine respiratory syncytial virus in outbreaks of respiratory disease in Norway

BACKGROUND Bovine respiratory syncytial virus (BRSV) is one of the major pathogens involved in the bovine respiratory disease (BRD) complex. The seroprevalence to BRSV in Norwegian cattle herds is high, but its role in epidemics of respiratory disease is unclear. The aims of the study were to investigate the etiological role of BRSV and other respiratory viruses in epidemics of BRD and to perfo...

Bovine respiratory syncytial virus.

Bovine respiratory syncytial virus (BRSV) is a major cause of respiratory disease and a major contributor to the bovine respiratory disease (BRD) complex. BRSV infects the upper and lower respiratory tract and is shed in nasal secretions. The close relatedness of BRSV to human respiratory syncytial virus (HRSV) has allowed researchers to use BRSV and HRSV to elucidate the mechanisms by which th...

Bovine respiratory syncytial virus.

The current knowledge is reviewed in regards to the importance of bovine respiratory syncytial virus in the bovine respiratory disease complex. The epidemiology, clinical disease, pathologic findings, pathogenesis, diagnosis, treatment, and prevention of this viral disease are discussed.

Bovine respiratory syncytial virus infection.

Bovine respiratory syncytial virus (BRSV) belongs to the pneumovirus genus within the family Paramyxoviridae and is a major cause of respiratory disease in young calves. BRSV is enveloped and contains a negative sense, single-stranded RNA genome encoding 11 proteins. The virus replicates predominantly in ciliated respiratory epithelial cells but also in type II pneumocytes. It appears to cause ...
