Abstract
Objectives. To identify the species of Leishmania present in the skin lesions of patients and Lutzomyias living in endemic areas of La Libertad, Peru. Materials and methods. Molecular methods based on PCR and RFLP were used, which allowed to have efficient data with small amounts of samples (small specimens), due to their high sensitivity and ease of application in the field work. Results. The results of PCR of clinical samples of patients and insect vectors showed the presence of Leishmania (V.) peruviana as a major causative agent of andean leishmaniasis transmitted by Lutzomyia peruensis. The presence of Leishmania (V.) guyanensis in Lutzomyia ayacuchensis, was found as well. Conclusions. The presence of L. (V.) peruviana and L. (V.) guyanensis in the Andean areas under study was found. These findings remark the need of a wider research about the geographical distribution of L. (V.) guyanensis and clinical features related to the infection in endemic areas of cutaneous leishmaniasis.
