RESPIRATORY SYNCITIAL VIRUS (RSV)
Bovine respiratory syncytial virus (RSV) is a pneumovirus belonging to the Paramyxoviridae family. It is closely related to human RSV which often infects the airways of children. Both are single-stranded RNA enveloped viruses. In bovines, RSV causes respiratory infections in young animals and dairy cows. The virus is mainly present in the lower airways (the lobes of the lung) where it damages ciliated epithelial cells which normally protect the lung against microbial invasion. RSV infection often leads to secondary bacterial infection, notably with P. haemolytica and C. pyogenes.
The symptoms of the disease are hyperthermia, coughing, nasal and ocular discharge, anorexia and dyspnoea (if the disease is progressing towards fatal pneumonia). In dairy cows, milk production falls off. RSV is transmitted by direct contact through nasal secretions, and its spread is favoured by proximity, e.g. in winter stabling and as a result of licking in the milking room.
