Resumo
This study aimed to investigate the prevalence of anti-Leptospira spp, identify the most prevalent serovars and to assess possible factors associated with Antileptospire
seroprevalence in urban dogs in Araguaina city,Tocantins state. A cross-sectional study covering the canine population residing in urban areas was conducted. Household collection of sera was performed by prior consent of the dog owners. The houses that were involved in the study were drawn previously it started. There were analyzed 275 samples at total. Samples were obtained through cephalic vein puncture, with a 25 x 7 needle and then transferred to 5 to 10 ml test tubes with gel separator sequentially centrifuged, cryopreserved and
sent for laboratory diagnosis of leptospirosis, at the Department of Veterinary Medicine at Federal University of Goiás Veterinary Medicine School (DMV / EV / UFG), which were processed by the microscopic agglutination test. In each
household, a questionnaire was applied to obtain data on the possible associated factors that were analyzed by bivariate analysis. The leptospira seroprevalence detected was 13,8%, the most prevalent serovar was Castellonis (26.3%) and,
Pyrogenes and Pomona, both with 10,5% of seropositive. The search for factors associated with infection by leptospira demonstrated statistically significant positive association between the variables season, rainy season (p = 0,03) and the
location Sonhos Dourados (p = 0,02). The results showed that Araguaina city canine leptospirosis presents a different epidemiological profile of most Brazilian regions surveyed.
