Toxoplasmosis is a zoonosis of worldwide distribution, resulting from infection by Toxoplasma gondii, an obligate intracellular protozoan those humans, mammals and birds. Dogs have been focused, as indicators of environmental and human contamination, and due to the mechanical ability to act as hosts sporulated oocysts according to the habit of xenosmofilia.Thus, this study aimed to: (a) verify the occurrence of anti-T. gondii in dogs in the Middle Para?ba, Volta Redonda, State of Rio de Janeiro and (b) region determine the factors that are associated with natural infection with this etiologic agent in dogs in the region.To this end, serum samples from 297 dogs were collected in a region of the city, which were processed and tested for ELISA, the results were statistically evaluated for observation of possible risk factors related to T. gondii, comparing data obtained from applying a specific questionnaire. The prevalence of 43.8% positivity among the tested animals was observed. Factors such as diet, eating raw meat, access to the street, where the animal resided region, age and race were not statistically significant as risk factors for infection of T. gondii in the bivariate analysis, while sex and contact with cats were significant as risk factors for infection, with p = 0.03 and 0.00002, respectively. When we performed a multivariate analysis, race and contact with cats became significant, with p values = 0.0334 and 0.0000, respectively. Given our results, we can conclude that the likely source of infection in the dog studied in the city of Volta Redonda region is the ingestion of oocysts, since dogs that had contact with cats showed 3 times more likely to have seropositive T. gondii. Thus, it is understood that canine habit of Xesnomofilia should be better studied to clarify whether it may represent a risk factor for human infection.
