Zusammenfassung:Bovine genital campylobacteriosis (BGC) is a venereal disease caused by Campylobacter fetus subsp. venerealis. In countries with large cattle herds, such as Brazil, where the use of natural breeding as a reproductive strategy is a common practice, BGC is considered an important cause of reproductive failure and economic losses. In these cases, the bull is the asymptomatic carrier of the bacterium and the infected females can have infertility and even abortions. The techniques for the diagnosis of C. fetus are isolation in culture medium and identification by biochemical tests, immunofluorescence, immunoenzymatic assays and molecular techniques. Disease control is based on vaccination with bacterins. This review described the epidemiology, etiology, pathogenesis, and advances in the diagnosis and control of BGC. Key words: Campylobacter fetus subsp. venerealis, infertility, venereal disease, beef cattle. A campilobacteriose genital bovina (CGB) e uma importante enfermidade de carater venereo causada por Campylobacter fetus subsp. venerealis. Em paises com grandes rebanhos bovinos, como o Brasil, onde o uso da monta natural como estrategia reprodutiva e uma pratica corrente, a CGB e considerada uma importante causa de falhas reprodutivas e perdas economicas. Nestes casos, o touro e o portador assintomatico da bacteria e as femeas infectadas podem apresentar infertilidade e ate mesmo abortos. As tecnicas para o diagnostico de C. fetus sao o isolamento em meio de cultura e identificacao por testes bioquimicos; imunofluorescencia; ensaios imunoenzimaticos e tecnicas moleculares. O controle da doenca e baseado em vacinacao. Neste sentido, esta revisao consiste em uma abordagem sobre a epidemiologia, a etiologia, a patogenia, os avancos no diagnostico e controle da CGB. Palavras-chave: Campylobacter fetus subsp. venerealis, infertilidade, doencas venereas, bovinos de corte.
