The present study aimed to investigate the prevalence of antibodies against Leptospira spp., identify the serovars and to evaluate possible factors associated with antibodies serological prevalence in urban dogs of a municipality in the AmazonCerrado-ecotone. We analyzed 275 sera samples, representative of the canine population of the urban area of the municipality. Samples were collected from random families. Antibodies research was performed by microscopic agglutination test (MAT), golden standard for the diagnosis of leptospirosis. Those responsible for the animals were given a structured questionnaire, elaborated with variables related to the animals, owners and the environment, to evaluate possible associated factors. Data were submitted to univariate analysis, using chi-squared test with Yates correction or Fisher’s exact test. The seroprevalence was 13.8%, with a predominance of Castellonis (26.3%), Pyrogenes (10.5%). and Pomona (10.5%) serovars. We observed statistically significant association (p<0.05) between Leptospira spp. infection and rainy season, temporarily flooded areas, presence of native vegetation and solid waste accumulation. The results showed that, in the studied area, canine infection had an epidemiological profile partially different from the profiles reported in most Brazilian regions, especially regarding the potential role of wild reservoirs as a source of infection.
