Item Acesso aberto (Open Access) Canine antibody response to Lutzomyia longipalpis saliva in endemic area of visceral leishmaniasis(Universidade Federal do Pará, 2016-06) BATISTA, Luís Fábio da Silva; MATTA, Vânia Lúcia Ribeiro da; TOMOKANE, Thaise Yumie; PACHECO, Acácio Duarte; SILVEIRA, Fernando Tobias; ROSSI, Claudio Nazaretian; MARCONDES, Mary; LAURENTI, Márcia DalastraIntroduction: Canine exposure to Lutzomyia longipalpis bites and the potential of Leishmania infantum transmissibility for the vector were evaluated. Methods: Immunoglobulin G (IgG) anti-Lu longipalpis saliva and -L. infantum, and blood parasite load were determined in dogs from endemic areas of visceral leishmaniasis. Results: Blood parasitism was similar between symptomatic and asymptomatic dogs. IgG anti-L. infantum was higher in symptomatic dogs, but IgG anti-Lu. longipalpis saliva was mostly observed in higher titers in asymptomatic dogs, indicating vector preference for feeding on asymptomatic dogs. Conclusions: Our data suggest a pivotal role of asymptomatic dogs in L. infantum transmission in endemic areas.
