Population structure and evidence for bothclonality and recombination among Brazilian strains of the subgenus Leishmania(Viannia)

Parasites of the subgenus Leishmania (Viannia) cause varying clinical symptoms ranging from cutaneous leishmaniases (CL) with single or few lesions, disseminated CL (DL) with multiple lesions to disfiguring forms of mucocutaneous leishmaniasis (MCL). In this population genetics study, 37 strains of L. (V.) guyanensis, 63 of L. (V.) braziliensis, four of L. (V.) shawi, six of L. (V.) lainsoni, seven of L. (V.) naiffi, one each of L. (V.) utingensis and L. (V.) lindenbergi, and one L. (V.) lainsoni/L. naiffi hybrid from different endemic foci in Brazil were examined for variation at 15 hyper-variable microsatellite markers.

Comparative microsatellite typing of new world leishmania infantum reveals low heterogeneity among populations and its recent old world origin.

Leishmania infantum (syn. L. chagasi) is the causative agent of visceral leishmaniasis (VL) in the New World (NW) with endemic regions extending from southern USA to northern Argentina.

Genetic diversity evaluation on Portuguese Leishmania infantum strains by multilocus microsatellite typing

Leishmania infantum is the main etiological agent of zoonotic visceral leishmaniasis in the Mediterranean region, including Portugal, but, given its low isoenzyme diversity in this country, the population structure is poorly known. A set of 14 polymorphic microsatellite markers was studied on 136 Portuguese Leishmania strains isolated from different hosts, geographic regions and different clinical forms. A total of 108 different genotypes were found, which is a degree of genetic diversity comparable to other regions, even within zymodeme MON-1.
