Abstrakt: The prevalence of Leptospirosis in goat herds of the State of Minas Gerais has seldom been studied. The present research had as its objectives: (1) investigate the seroprevalence of Leptospirosis in the county of Uberlândia, MG, (2) verify the Leptospirosis serovars, and (3) identify the risk factors associated with infection on the farms examined. Serum samples from 230 animals in 11 properties were tested using the microscopic agglutination test. An epidemiological examination furnished data for analysis regarding the risk factors. The prevalence of Leptospirosis was found to be 31.3% with variation from 1:100 to 1:800. The most frequent serovars were: Autumnalis (30.30%), Tarassovi (19.20%), Pyrogenes (13.13%), and Icterohaemorrhagiae (11.11%). The ages and races of the animals were among the risk factors found to be significantly correlated (P<0.05) with infection. At the farm level, the intensity of production, use of salaried workers, and association of other animals were all found to be related with the frequency of Leptospirosis. The results demonstrated that inadequate management was a factor which favored the occurrence of infection in the region of the study.
