BRSV

Bovine respiratory syncytial virus (BRSV) is pneumovirus closely related to human respiratory syncytial virus (RSV) that is a common cause of respiratory disease in cattle, particularly calves. It is a negative-sense, single-stranded RNA virus that replicates in the cytoplasm of the cell. Similarly to other single-stranded RNA viruses, the genome of BRSV has a high mutation rate, which results in great antigenetic variation. Thus, BRSV can be split into four different subgroups based on antigen expression.
