Seroprevalence of anti-Toxoplasma gondii antibodies in dogs from rural area of Nossa Senhora da Glória, Sergipe, Brazil



Toxoplasma gondii is a protozoan parasite with worldwide distribution. Dogs are considered sentinel animals, useful for the detection of environmental infections and outbreaks of disease through serological surveys. Considering this, we aimed to assess the seroprevalence of toxoplasmosis in dogs from rural areas of the hinterland of the state of Sergipe, Northeastern Brazil. A total of 77 blood samples were collected from dogs and analyzed by the Indirect Hemagglutination test for the detection of anti-T. gondii antibodies Samples were considered positive when titers greater than or equal to 1:16 were observed. In addition, an epidemiological questionnaire designed to identify characteristics of the animal was performed to owners regarding sex, breed, age, sterilization, access to areas outside the house, environmental hygiene, contact with other animals and dog food. A total of 49.3% of dogs (n = 38) were positive for anti-T. gondii antibodies, most with high titers (44.7%). A higher relative frequency of seropositivity was observed in male dogs, not sterilized, mixed breed, which were fed exclusively on homemade food and had access to the street and contact with other animals. Taken together, our data reinforce the importance of developing health education actions within the scope of public health aimed at preventing this zoonosis.
