Seroprevalence of Toxoplasma gondii, Neospora caninum, and Leishmania spp. in hunting dogs from Mato Grosso do Sul, Brazil
ABSTRACT: Toxoplasmosis, neosporosis, and leishmaniasis are important diseases of worldwide distribution and can affect both pets and humans. Hunting dogs have been trained to hunt domestic and wild animals, which makes them more exposed to parasitic infections. The present study aimed to evaluate the seroprevalence of Toxoplasma gondii, Neospora caninum, and Leishmania spp. in hunting dogs from a rural area in Mato Grosso do Sul, Brazil. Serum samples were collected from 39 American Foxhound dogs, and the sex and age variables were recorded. Serum samples were subjected to an indirect fluorescent antibody test (IFAT) to detect antibodies. Seroprevalence was 35.9%, 15.4%, and 2.6% for Toxoplasma gondii, Neospora caninum e Leishmania spp., respectively. There was no statistical difference between genders for these diseases (P>0.05). Results demonstrated a circulation of these protozoa in hunting dogs in a rural area of the state of Mato Grosso do Sul, which can contribute to the epidemiology of these diseases.
