Leishmania infantum Genetic Diversity and Lutzomyia longipalpis Mitochondrial Haplotypes in Brazil

الملخص EN

Leishmania infantum is the etiological agent of visceral leishmaniasis (VL) in the Americas with domestic dogs being its major reservoir hosts.

The main VL vector is the sandfly Lutzomyia longipalpis, while other Lutzomyia species may play a role in disease transmission.

Although the genetic structure of L.

infantum populations has been widely evaluated, only a few studies have addressed this subject coupled to the genetic structure of the respective sandfly vectors.

In this study, we analyzed the population structure of L.

infantum in three major VL endemic areas in Brazil and associated it with Lutzomyia longipalpis geographic structure.
