The seroprevalence of leptospirosis in the goat flocks created in the Minas Gerais State is little studied. The objectives of this study were (i) to investigate the seroprevalence of leptospirosis in goats of Uberlândia city, MG and to verify predominant serovars; (ii) to identify to the risk factors associates to the infection in the studied properties; (iii) to carry through the isolation and the identification of Leptospira spp. in urine samples of seropositive animals and, (iv) to identify alterations in urinalysis. Were analyzed 230 samples of serum proceeding from 11 properties, using the microscopic agglutination test (MAT). An epidemiologist inquiry was elaborated which gave supplied for the analysis of the risk factors. It was used Stuart s medium base for the isolation of leptospiras. In urinalysis, the samples were submitted to the examinations physical, chemical and evaluation of the urinary sediment. The prevalence of leptospirosis was of 31,30%, with titers varying the 1:100 to 1:800. More found serovars were autumnalis (30,30%), tarassovi (19,20%), pyrogenes (13,13%) and icterohaemorrhagiae (11,11%). The age and the breed had met enter the estatistic significant factors of risk for the infection between the animals. In the properties, the intensive system of production, the use of wage-earning workmanship and the creation of other animal species had been related with the higher frequencies of leptospirosis. It was not possible to isolate leptospiras of the urine samples and had not been found alterations in urinalysis that they suggested infection for the bacterium. The results had shown that the inadequate behaviors of handling in the properties favor the occurrence of one high number of animals displayed to the infection for leptospiras in the goat flocks of Uberlândia.
