Leptospirosis is a zoonotic disease that occurs worldwide, affecting pets and livestock that can be a source of infection for humans, considered therefore an important disease in public health. Thus, an investigation was made into the occurrence of anti-Leptospira agglutinins in several animal species on a farm located in the municipality of Uberlândia, state of Minas Gerais, Brazil. A total of 172 blood serum samples were collected from five species: cattle, dogs, goats, horses and sheep. The diagnosis was performed by means of the microscopic agglutination test (MAT), using a collection of 12 live antigens. Of the 172 animals evaluated, 62 (36%) were seroreactive, and the most frequent serovars in each species were: Hardjo (54.54%), Icterohaemorrhagiae (27.27%), and Autumnalis (18.18%) in cattle; Icterohaemorrhagiae (37.5%), Autumnalis (31%), Canicola (18.7%) and Hardjo (12.5%) in dogs; Grippotyphosa (75%) and Hardjo (25%) in goats; Icterohaemorrhagiae (50%), Grippotyphosa (37.5%) and Hardjo (12.5%) in horses, and Hardjo (34.78%); Grippotyphosa (26.08%); Bratislava (17.39%), Autumnalis (17.39%) and Icterohaemorrhagiae (4.4%) in sheep. It is believed that the occurrence of anti-Leptospira agglutinins can be traced back to a source of infection that is common to these species, or that the agent was probably transmitted between them because they live in close proximity to each other.
