Resumo: | Cats, as definitive host, play an important role in the transmission of Toxoplasma gondii. This study aimed to establish the seroprevalence of anti-T. gondii immunoglobulins G and M, and determine the frequency of oocysts in the feces of the domestic cat population in Rio de Janeiro, Brazil. We also aimed to study the association between T. gondii infection and age, sex, breed, lifestyle, diet and retroviral infection. A total of 108 cats were included in the study and fecal samples of 54 of those cats were obtained. Only 5.6% of the cats were seropositive for anti-T. gondii immunoglobulins using the indirect hemagglutination test. None of the 54 cats presented oocysts in their fecal samples. Although not statistically significant, males, mixed-breed, free-roaming and cats aged two years and older were found to be more exposed. Age, lifestyle and the use of litter boxes were found to play an important role as risk factors. Anemia and retroviral infections were independent of T. gondii infection. No antibodies were detected in the majority of cats (94.4%), indicating that those cats had never been exposed to the parasite and, therefore, once infected, they could present the risk of shedding large numbers of oocysts into the environment. |

Os gatos, como hospedeiros definitivos, apresentam um papel fundamental na transmissão do Toxoplasma gondii. Nosso estudo teve como objetivo determinar a presença de imunoglobulinas G e M anti-T. gondii, e a frequência de oocistos nas fezes de uma população de gatos domésticos do Rio de Janeiro, Brasil. Objetivou-se ainda estudar a associação da infecção por T. gondii com a idade, sexo, raça, estilo de vida, dieta e infecção por retrovírus. Um total de 108 gatos foi incluído no estudo e 54 amostras de fezes foram obtidas desses animais. Somente 5,6% dos gatos foram sororreagentes para T. gondii, utilizando-se o teste de hemaglutinação indireta. Nenhum dos 54 gatos apresentou oocistos em suas amostras fecais. Embora sem comprovação estatística, machos, sem raça definida, com acesso livre às ruas e gatos com mais de dois anos de idade tenderam a ser mais expostos ao parasito. Idade, estilo de vida e uso de caixa de areia foram considerados importantes fatores de risco. Anemia e infecção por retrovírus não apresentaram relação com infecção por T. gondii. Não foram detectados anticorpos na maioria dos gatos (94,4%), indicando que esses gatos nunca foram expostos ao parasito e que, se infectados, poderão eliminar grande número de oocistos no ambiente.
