dc.descriptionWe investigated the effects of Lutzomyia longipalpis salivary glands homogenate of wild-caught and laboratory-reared vectors on the lesion evolution and immunomodulation of the infection caused by Leishmania (Leishmania) amazonensis. To compare the effect of both salivary glands homogenate (SGH), C57BL/6 mice were inoculated Subcutaneously into the hind footpads or into the ear dermis with 10(6) promastigotes in the presence or not of SGH from wild-caught and laboratory-colonized sand flies. Comparing SGH groups, the lesion size was lower in mice co-inoculated with wild-caught SGH, as the parasitism and the infiltration of macrophages at the inoculation site. Wild-caught SGH also determined lower production of IL-4 and IL-10 but higher IL-12 levels compared with laboratory-reared SGH. Our findings address a probable bias by using SGH from laboratory-colonized sand flies instead of wild-caught vector SGH in studies concerning saliva effects. A possible mild influence of sand fly saliva in natural infections caused by Leishmania is also speculated, as infection is transmitted by wild and not by laboratory-reared vectors
