Abstract

Introduction: 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. (AU)
