Leptospirosis is a zoonosis that affects all mammals, including cattle. The infection acute to the chronic character, with great clinical polymorphism, and is caused by bacteria of the genus Leptospira spp. Its importance is related to causing clinical signs in cattle, which is mostly in the reproductive and abortions, stillbirths and infertility or productive as a drop in milk production and mastitis. The aim of this study was to conduct a seroepidemiological dairy cattle herds in the city of Guaíra – São Paulo. We analyzed 104 samples of blood serum of dairy cattle from 5 properties through antibody testing by Microscopic Agglutination Test (MAT). Besides the test, an epidemiological questionnaire was designed to assess risk factors for the occurrence of infection. The prevalence was 46.15%, the most prevalent serovars were Hardjo(39.53%); Grippotyphosa (24.42%); Wolffi (19.77%) Hebdomadis (12.79%); Icterohaemorragiae (2,33%) and Pomona (1.16%). It was observed that multiparous cows were more prone to disease occurrence. The results suggest that infection in these properties may be due the trade of animals due to the higher prevalence of serovar Hardjo, and that the absence of vaccination is a risk factor for leptospirosis.
