Abstract

Species ofgenus are intracellular parasites responsible for severe zoonotic diseases worldwide, such as leishmaniasis. In Brazil, the most important species is. In the northern region, the state of Pará is notable, with a high number of cases reported in recent years. The second largest number of cases of human visceral leishmaniasis in the region in recent years has been reported in the city of Marabá (Pará state). We investigated the prevalence ofin domestic dogs from Marabá in Amazon region in Brazil.A total of 400 blood samples were tested using the dual-path platform chromatographic immunoassay (DPPCVL-Bio-Manguinhos), and molecular diagnosis based in cathepsin L-gene, which has better specificity and sensitivity than other similar tests.The prevalence ofwas 75.5% (302/400) in the serological test, and 59.25% (237/400) in molecular diagnosis, and 45.5% (182/400) in both tests.The results confirmed that the parasitewas prevalent in the dog population of the studied region and adoption of appropriate public policies are urgently needed.
