BENITEZ, Irene R. et al. Detección molecular de Leishmania (Viannia) lainsoni Silveira, Shaw, Braga & Ishikawa, 1987 (Kinetoplastida: Trypanosomatidae) en humanos de Paraguay. Rev. Inst. Med. Trop. [online]. 2019, vol.14, n.1, pp.21-28. ISSN 1996-3696.

Leishmaniasis is one of the most neglected tropical diseases worldwide caused by the parasite Leishmania. In Paraguay the species responsible for cutaneous leishmaniasis (CL) is L. (Viannia) braziliensis. Here we report a case diagnosed with Leishmaniasis, and molecular analyses using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) demonstrate that the case was caused by L. (V.) lainsoni. This is the first record of this species for Paraguay, with which we extend the distribution range of the parasite 1,430 km southwards from the southernmost previous known locality. More studies are needed to know the actual incidence of this species in cases of CL in Paraguay, and to identify natural reservoirs in the wild.

Keywords : Epidemiology; Leishmaniasis; PCR-RFLP; South America.
