COCHERO, Suljey et al. Natural infection of Lutzomyia cayennensis cayennensis with trypanosomatid parasites (Kinetoplastida: Trypanosomatidae) in Los Montes de María, Colombia. Rev Cubana Med Trop [online]. 2007, vol.59, n.1. ISSN 0375-0760.

The presence of sand flies naturally infected with trypanosomatid parasites was determined in Los Montes de María, Colombia, a region considered endemic for visceral and cutaneous leishmaniasis. Phlebotomines were collected using CDC light-traps, and sticky traps soaked with castor oil placed in the peri and intradomestic habitats. Six species of Lutzomyia were morphologically identified among the 159 sand flies captured: Lu. evansi, Lu. cayennensis cayennensis, Lu. trinidadensis, Lu. atroclavata, Lu. gomezi and Lu. dubitans. A DNA band of 800 pb corresponding to the small-subunit ribosomal RNA gene (ssrRNA) of the family Trypanosomatidae was amplified in one pool of nine females of Lu. cayennensis cayennensis. This finding constitutes the first evidence of natural infection of this sand fly species with trypanosomatid parasites in Los Montes de María.
