dc.descriptionSera of 11 wild Cerdocyon thous foxes from an endemic area for American visceral leishmaniasis were tested for the presence of antibodies against salivary gland homogenates (SGH) of Lutzomyia longipalpis. All foxes had higher levels of anti-Lu. longipalpis SGH antibodies than foxes from non-endemic areas, suggesting contact between foxes and the vector of visceral leishmaniasis. Sera of humans and dogs living in the same area were also tested for reactivity against Lu. longipalpis SGHs and had a lower proportion of reactivity than foxes. Antibodies against Leishmania chagasi were not detected in any of the foxes, but three foxes showed the presence of parasites in the bone marrow by direct examination, PCR or by infecting the vector. Both humans and dogs had higher levels of anti-Le. chagasi IgG antibodies than C. thous. The finding of an antibody response against saliva of Lu. longipalpis among C. thous together with the broad distribution of the vector in resting areas of infected foxes suggests that the natural foci of transmission of Le. chagasi exists independently of the transmission among dogs and humans.
