Aborto causado por rinotraqueítis infecciosa bovina (IBR)

Resumen

Infectious bovine rhinotracheitis (IBR) is a highly contagious disease of cattle. Bovine herpesvirus type 1, of the Herpesviridae family, is a very important pathogen in the development of the disease. There are different strains that can cause different forms of the disease: HBV-1.1 are strains specific to acute respiratory disease, while, HBV-1.2.a and HBV-1.2.b are strains causing respiratory disease and reproductive disease, on the other hand, they are also responsible for infertility, embryonic death and abortions. HBV-1. 3.a and HBV-1.3.b are less common causes of encephalic disease. Primary infection is accompanied by various clinical manifestations, such as infectious bovine rhinotracheitis, abortion, infectious pustular vulvovaginitis and systemic infection in neonates. When animals survive the pathogenicity of the virus, a lifelong latent infection is established in the sensory nerve ganglia, causing any immunological variation to allow reinfection and thus reactivation stimuli can lead to viral re-excretion, responsible for the maintenance of HBV-1 within a herd for extended periods of time. Being a highly contagious virus, the most effective and reliable way to combat the disease in cattle herds is to establish a correct sanitary plan that allows the proper immunization of animals against the virus, thus avoiding the productive, economic and sanitary consequences. The present bibliographic review seeks to compile the most updated and important information on IBR worldwide and nationally, giving it the required importance as a cause of abortions in cattle.
