title: Lutzomyia migonei as putative vector of visceral leishmaniasis in La Banda, Argentina.
abstract: Four autochthonous cases of human visceral leishmaniasis (VL) were reported in La Banda, Santiago del Estero from June 2007 to May 2008. In the vicinity of these cases there were 3/47 rK39 sero-positive dogs, and another 4 dogs with VL were reported by passive surveillance. The sero-positive dogs and infected humans lived within a 3.1 km radius. Phebotomine sand fly captures were performed twice during November/December 2007 and April 2008. In 20 of the 59 sampled sites in the areas of the human and canine cases (220 night/traps) 151 phlebotomine sand flies were collected and consisted of: Lutzomyia migonei 93%, Lutzomyia cortelezzii 5.6% and Lutzomyia neivai 1.4%. We propose that there was an enzootic cycle of VL with accidental human transmission due to L. migonei and suggest that there be a surveillance of human isolated cases of VL within the L. migonei dispersion area.
