IBRLA - LSIVET MILK IBR SCREENING ADVANCED
Infectious bovine rhinotracheitis (IBR) is caused by a herpesvirus (BHV-1) which infects the airways causing respiratory tract problems (tracheitis and rhinitis), fever, abortion and infertility. It can lead to death when the disease rapidly spreads through a herd. IBR is transmitted through direct contact via respiratory, ocular and genital secretions. The IBR virus has an immunosuppressive effect and infection can predispose the host to secondary bacterial infection. Infection can also be latent in which, although the primary infection appears to have been cleared, the virus is still present in the lymph nodes and can be reactivated to spread throughout the body. Although the incidence and prevalence of the disease varies on different continents, it is present throughout the world and nearly 50% of all adult bovine herds have already been exposed.
