Resumen

The state of Rio de Janeiro is epidemiologically classified as a region of low incidence for American visceral leishmaniasis (AVL); however, endemic areas have expanded dramatically in recent years. In 2009 and 2010, autochthonous cases of AVL were reported in the municipality of Maricá and in the neighborhood of Laranjeiras in the city of Rio de Janeiro, respectively. In 2006, samples isolated in infected animals in the coastal area of the municipality of Mangaratiba were characterized as L. (L.) chagasi. In 2002, on Marambaia Island, located in Mangaratiba, only cases of American cutaneous leishmaniasis (ACL) were recorded. This study aimed to reassess the prevalence of CVL and identify the phlebotomine fauna on Marambaia Island, Mangaratiba, in 2012. To this end, a canine serological survey was carried out using IFA, ELISA and DPP techniques. In addition, phlebotomi were captured with the help of light traps, HP type.  The census totaled 116 dogs, and 17 animals tested positive with prevalence of 14.6%.  From April to November 2012, 2,524 sandfly specimens of nine different species were captured. We observed the maintenance of CVL prevalence in the region, as well as the presence of the Lutzomyia longipalpis vector.
