Infection with bacteria of the genus Leptospira spp. is the origin of the clinic disease called leptospirosis and has significant impact on equine husbandry and public health. This study aimed to investigate the prevalence of anti-Leptospira spp antibodies. in horses in the municipality of Rorainópolis, State of Roraima, Brazil's Amazon, and identify the predominant serotypes in positive serological reactions, and possible factors associated with the presence of Leptospira spp. A cross-sectional observational study using an epidemiological questionnaire and the collection of 303 samples of equine rural and urban areas that were only entered in the research after reading and signing the informed consent and informed the owner was accomplished. Samples of equine serum used in the research were obtained by puncturing the jugular vein by means of a closed vacuum collection system and sent for analysis by microscopic agglutination test (MAT / MAT) on Leptospirosis Diagnostic Laboratory of the Veterinary School and Animal Science of the Federal University of Goiás. Statistical analyzes were performed using chi-square test that provided evidence of potential factors associated with Leptospira spp. As a result of research, it was observed prevalence of 72.94% of infections in horses, prevalence of 96.43% of foci of infection, and the prevalence of serovars Patoc, Sentot, Icterohaemorrhagiae, Grippotyphosa, Hardjoprajitno and Castellonis in serological reactions positive. Presence of rodents, Veterinary care and Use of animals were found to associads factors for infection by Leptospira spp. Therefore, it was found to endemic infection with Leptospira spp. in the municipality due to the high number of cases and outbreaks, and significant occurrence of positive for the serovars Sentot, Grippotyphosa, Butembo and castellonis indicate the contact and the circulation of these serotypes also in wild animals, and the occurrence of positive for the serovars icterohaemorrhagiae and serovar respectively suggests contact with synanthropic rodents and cattle.
