摘要
Introduction: Herein, we assessed the seroprevalence and spatial distribution of Leishmania infantum in dogs in Garanhuns, Northeastern Brazil. Methods: Sera samples (n = 242) were analyzed using an enzyme- linked immunosorbent assay (ELISA). The spatial distribution of dogs seropositive for anti- Leishmania infantum antibodies was evaluated using kernel density estimation. Results: A total of 2.4% (6/242) of the animals were seropositive for anti- Leishmania infantum antibodies. The kernel map showed their distribution to be heterogeneous over the city, with a hotspot in the northeastern region. Conclusions: The reported data illustrate the circulation of parasites of the genus Leishmania in a canine population.
