Kernel BRSV Antibody Test Kit is a rapid and specific presumptive screening test for the dection of antibody to Bovine Respiratory Syncytial Virus in serum of cattle.

Bovine Respiratory Syncytial Virus (BRSV) belongs to the genus Pneumovirus of the family Paramyxoviridae.BRSV is closely related to Human-, Ovine- and Caprine RSV. A primary BRSV infection can result in severe lower respiratory tract disease in susceptible cattle, but asymptomatic infections do occur as well. In endemic areas, clinical disease is most apparent in calves, and resembles the disease in infants infected with HRSV. After a primary natural BRSV or HRSV infection, the protection against re-infection is shortlived and multiple re-infections are common. Primary BRSV infections in individual animals can easily be monitored by titration of sequential serum samples of individual cows. A fourfold rise of antibody titer in two successive sera can be considered as a seroconversion (=primary infection) in that particular period.
