In Amazonian Brazil the etiological agents of American cutaneous leishmaniasis (ACL) belong to at least seven Leishmaniaspecies but little is known about the putative phlebotomine sand fly vectors in different biomes. In 2002–2003 a survey of the phlebotomine fauna was undertaken in the “Floresta Nacional do Tapajós”, Belterra municipality, in the lower Amazon region, western Pará State, Brazil, where we recently confirmed the presence of a putative hybrid parasite, L.(V.) guyanensis × L.(V.) shawi shawi. Sand flies were collected from Centers for Disease Control (CDC) light traps, Shannon traps and by aspiration on tree bases. Females were dissected and attempts to isolate any flagellate infections were made by inoculating homogenized midguts into Difco B45medium. Isolates were characterized by monoclonal antibodies and isoenzyme electrophoresis. A total of 9,704 sand flies, belonging to 68 species or subspecies, were collected. Infections were found in the following sand flies: L.(V.) naiffiwith Psychodopygus hirsutus hirsutus(1) and Ps. davisi(2); and L.(V.) shawi shawiwith Nyssomyia whitmani(3) and Lutzomyia gomezi(1). These results provide strong evidence of new putative transmission cycles for L.(V.) naiffiand L.(V.) s. shawi. |
