Respiratory syncytial virus infection in cattle.
Bovine respiratory syncytial virus (RSV) is a cause of respiratory disease in cattle worldwide. It has an integral role in enzootic pneumonia in young dairy calves and summer pneumonia in nursing beef calves. Furthermore, bovine RSV infection can predispose calves to secondary bacterial infection by organisms such as Mannheimia haemolytica, Pasteurella multocida, and Histophilus somni, resultin...
متن کاملImmunology of bovine respiratory syncytial virus infection of cattle.
Bovine respiratory syncytial virus (BRSV) is a respiratory pathogen of cattle that causes severe disease in calves alone and as one of several viruses and bacteria that cause bovine respiratory disease complex. Like human RSV this virus modulates the immune response to avoid stimulation of a vibrant CD8+ T cytotoxic cell response and instead promotes a Th2 response. The Th2 skew sometimes resul...
متن کاملBovine 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 ...
متن کاملRespiratory Syncytial Virus Infection In Vitro*
Background and objectives: Alveolar macrophages (AMs) are targets for respiratory syncytial virus (RSV) infection in vivo and in vitro. However, only a minority ofAMs are permissive to acute RSV infection in vitro, and it is unknown whether this permissiveness may be related to the degree of cellular maturation that is achieved in vivo. Methods: By using density gradient centrifugation, in whic...
