Abstract

The objective of this research was to determine the seroprevalence of Leishmania infantum in dogs in the city of Primavera do Leste, Mato Grosso, Brazil. A total of 109 serological samples from dogs were analyzed, collected between August 2021 to March 2022, using rapid immunochromatographic test, TR DPP® (LVC BioManguinhos), and Immunoenzymatic Assay (ELISA), EIE-Canine Visceral Leishmaniasis (Bio-Manguinhos®, Fiocruz). IgG anti-Leishmania infantum antibodies were detected 4.6% (5/109) by DPP test. Regardless of results, all samples were submitted to ELISA test, of those 0.9% (1/109) was positive, the same having also been positive for the DPP, from asymptomatic, adult dog living in the urban area. This is the first autochthonous report of CVL in the municipality. Since Visceral leishmaniasis caused by L. infantum is a disease of One Health concern, the results obtained are essential to fill the epidemiological gap of in the region. Furthermore, the health authorities should implement surveillance actions in order to monitoring of dogs, as well as survey of sand flies, and health education programs to stimulate the prevention of the disease.
