Abstrakt: Brazil has a herd of over 9 million goats, and the northeast of Brazil is home to over 93% of this herd. Caprine mycoplasmosis are widely disseminated worldwide, being highly contagious with high rates of morbidity and mortality, causing considerable economic loss to goat herders. In addition, there has been a lack of research using molecular testing to monitor the health and detect Mollicutesin this herd in Brazil. Therefore, the aim of this study is to associate animal management with the presence of the caprine origin Mollicutesin goats, in the southwest region of the state of Bahia, Brazil. A cross-sectional study was conducted on twelve farms, and statistical analyses were performed to identify associations between the presence of Mollicutesand the management of goats. Molecular testing identified Mollicutesclass, Mycoplasma agalactiae(Ma) and M. conjunctivae(Mc), in the samples analyzed. Statistical associations were observed between animals from intensive livestock facilities and the presence of Mollicutesin nasal samples and dairy ranch animals and the presence of Mollicutesin ocular samples and animals from extensive ranching sites and positive results of Mollicutesin genital samples. We conclude that mycoplasmas are present in goat herds in the southwestern region of Bahia, which supports the need for more focused studies of mycoplasmas throughout the country. Our research also demonstrated the presence of two important opportunistic bacteria, Mc and Ma, and, to the best of our knowledge, this is the first time that M. conjunctivaewas detected in Brazilian goats by molecular testing.
