The present study aimed to investigate the presence of anti-Leishmania antibodies in samples of domiciled dogs and associate them with epidemiological indicators in the city of Lagarto, Sergipe. The diagnosis of Canine Visceral Leishmaniasis (CVL) was carried out in 755 dogs, where the rapid two-way platform immunochromatographic test (TR-DPP) (Fiocruz/Biomanguinhos) and the serological test of Enzyme-Linked Immunosorbent Assay (ELISA) were applied. The results showed that all homes with seroreactive dogs were close to abandoned land, squares and/or green areas. There was a significant association between seroactive animals and type of shelter (p=0.008); 54.8% had an indoor shelter and 45.2% of the dogs had a shelter outside their homes. The disease is geographically distributed in 14 (73.68%) of the 19 sample areas in the municipality. Of these, five (26.31%) had cases of Visceral Leishmaniasis in dogs and humans. Eight cases of Human Visceral Leishmaniasis (HVL) were reported during the years 2017 to 2020 in the municipality. Dogs that are located in areas of greatest risk impact the maintenance of natural foci of Leishmaniasis transmission to human and animal hosts in areas endemic for Visceral Leishmaniasis. Such results are essential to assist epidemiological surveillance in the municipality of Lagarto-SE with the implementation of control measures aimed at the insect vector of the disease, the sand fly, to prevent human and canine cases.
