Campilobacteriose genital bovina e tricomonose genital bovina: epidemiologia, diagnóstico e controle / Bovine genital campylobacteriosis and bovine genital trichomonosis: epidemiology, diagnosis and control

A presente atualização trata de duas das mais importantes doenças sexualmente transmitidas de bovinos, a campilobacteriose genital bovina e a tricomonose genital bovina. São abordados aspectos relacionados à epidemiologia destas doenças, principalmente em relação a sua distribuição no Brasil. Também são revisados aspectos importantes de diagnóstico, incluindo as técnicas e interpretação dos resultados, além de medidas de controle para ambas as doenças.

The present update deals with two of the most important sexually transmitted diseases of cattle: bovine genital campylobacteriosis and bovine genital trichomonosis. Epidemiological aspects, mainly their distribution in Brazil, alongside with their diagnosis in cattle are presented and commented. The main points in their diagnoses, including the description of the techniques and the interpretation of the results are also reviewed. Finally the control and prevention of both diseases are discussed.

Campilobacteriose genital bovina em rebanhos leiteiros com problemas reprodutivos da microrregião de Varginha - Minas Gerais / Bovine genital campylobacteriosis in dairy herds with reproductive problems of the microregion of Varginha, MG, Brazil

The frequency of bovine genital campylobacteriosis (BGC) in 157 cows from nine herds from the microregion of Varginha - Minas Gerais - Brazil was evaluated. Farmers use either artificial insemination and natural breeding after two insemination procedures or natural breeding. The diagnosis of BGC was performed by the direct fluorescent antibody test (DFAT) using vaginal mucus. All studied herds showed C. fetus infected animals and, of 157 animals, 40 (25.5 percent) were positive in DFAT: 7 (26.9 percent) from herds with natural breeding and 33 (25.1 percent) from herds with both artificial insemination and natural breeding after the second-to-third insemination. The high frequency of BGC found in this study shows that this disease is present among herds which have reproductive problems and the use of natural breeding after the second-to-third unsuccessful insemination could be a risk factor for the disease
