SUMMARY:

Toxoplasmosis is a very common infection in several species of animals. Domestic felines are of great importance for the life cycle of Toxoplasma gondii, since along with their feces, they carry oocysts into the environment that, under ideal environmental conditions, sporulate and will contaminate other animals, including humans. The manifestation of the disease is more common in immunocompromised dogs and cats, with broad symptoms and no pathognomonic signs, making toxoplasmosis difficult to diagnose in routine veterinary clinics. The objective of this study was to detect IgG anti-Toxoplasma gondii (T. gondii) antibodies and investigate possible risk factors associated with dogs and cats treated in clinics located in the Municipality of São José dos Campos in the State of São Paulo (SP). The samples were provided by Laboratórios Vetvale Centro de Diagnóstico e Especialidades Veterinárias Ltda, and Baldacin Salgado Serviços Veterinários S/S Ltda ME, both located in the municipality of São José dos Campo - SP. The analyzes were carried out using serum from 247 animals, 169 dogs and 78 cats. From the serum of dogs and cats that we had access to, a serological diagnosis was carried out using the Modified Agglutination Test (MAT) technique to detect anti-T. gondii IgG antibodies at the UFRRJ Parasitic Diseases Laboratory. The data on risk factors that we had access to were through the records and history of the animals that were provided for consultation by the Laboratory (such as age, breed and sex). The chi-square test was used to compare the number of positive animals with the risk factors associated with T. gondii infection in domestic dogs and cats. The prevalence of anti-T. gondii antibodies was observed in 63.91% of the dogs tested. In felines, seropositivity was found in 12.66% of the animals tested. No risk factors such as age, breed and sex showed significant differences in dogs or cats in the studied municipality. It is concluded that there is a high prevalence of T. gondii in dogs domiciled in São José dos Campos. More studies must be carried out to know the real impact of this zoonosis and investigate how these dogs are being infected.
