Summary
Of 6337 female sandflies dissected, 466 were found to have flagellates in their digestive tracts. A total of 28 sandfly species, or species groups, were dissected, yet flagellates were only found is six of these species or species groups. Of these, only two species of sandfly had leptomonads which were positively identified as Leishmania braziliensis. Sixteen strains of Le braziliensis were isolated from Lutzomyia umbratilis or Lu. anduzei.
