BOVINE BRUCELLOSIS: EMPHASIS ON PREVENTION AND CONTROL
Abstract
Every year Brazil advances in cattle production, facing challenges that cause economic losses, including diseases. This chapter aims to address the general aspects of brucellosis, with a focus on prevention and control. Brucellosis is a bacterial infection caused by bacteria of the genus Brucellas spp., of chronic evolution, whose main clinical sign in the herd is abortions in the final third of gestation, of wide worldwide distribution, of significant importance due to economic losses and its zoonotic character, in addition to being a notifiable disease. The economic importance attributed is related to the possibility of infection in humans, productive losses of the herd, death of animals, decrease in milk production, early disposal, elimination of animals of high zootechnical value and condemnation of carcasses at slaughter. It is estimated a loss of 10% to 25% of the productive efficiency of infected animals. Being considered an occupational disease, they affect farmers, handlers, veterinarians, vaccinators, laboratory workers, slaughterhouse workers, due to the routine of direct contact with infected animals and/or their secretions. In 2001, the government established the National Program for the Control and Eradication of Brucellosis and Tuberculosis (PNCEBT), revised by IN No. 10 of 2017. The PNCEBT recommends the vaccination of bovine and buffalo females between 3 and 8 months of age against brucellosis, elimination of carriers, tests with negative results for transit regardless of the purpose and certification of properties free of brucellosis or tuberculosis. The lack of knowledge and negligence about brucellosis puts the health of productive herds and citizens at risk.
