The seroprevalence in bovine was determined the risk factors associated with infection by Leptospira spp. In herds of the Kalunga Historical Site and Cultural Patrimony located in the municipalities of Cavalcante, Monte Alegre de Goiás and Teresina de Goiás, State of Goiás, in the area of Cerrado native and few areas with pastures formed. Blood samples were collected from 4,860 cattle of different races, genre and age groups, from 136 herds predominantly cut, under extensive management. An epidemiological questionnaire was used to identify the risk factors associated with the infection. The determination of anti-Leptospira antibodies was performed by the microscopic serum agglutination technique. The prevalence of positive cattle was 44.69%, with Serjoe serogroups (Wolffii and Hardjoprajtino serovars), Tarassovi serovar Tarassovi and Grippothyphosa serovar Grippotyphosa being the most frequent. Leptospira spp. was identified as a risk factor for infection. (OR 1.68 - 2.26), gender (OR 0.47), age (OR 2.91 - 2.96), presence of dog in the property (OR 1.32), contact with wild animals [Crabeating raccoon (OR 1.17), rodents (OR 1.11) and collared peccary (OR 1.09)], feeding (OR 1.3 - 2.56), mean annual temperature (OR 1.36), standard deviation of the seasonal (annual) temperature of the property (OR 1.76), altitude (OR 1.06) and rainy season harvest (OR 1.11) and as a protection factor the presence of cat in the property (OR 1.11). Continuing education in health and hygienic-sanitary measures should be implemented to minimize the effects of the risk factors identified in this study and reduce the prevalence of Leptospira spp. in these herds.
