title: A battery of 12 microsatellite markers for genetic analysis of the Leishmania (Viannia) guyanensis complex.
abstract: We used 12 microsatellite markers developed for Leishmania braziliensis to genotype 28 strains of the main species of the Leishmania guyanensis complex (i.e. L. guyanensis and L. panamensis) collected in Ecuador and Peru. The important heterozygote deficits observed in these populations are similar with the previous data obtained in L. braziliensis and raise again the debate on the reproductive mode of these protozoan parasites. The data showed genetic polymorphism and geographical differentiation giving information on population structure of the L. guyanensis complex. Regarding the two species, this study enhances again the debate on the taxonomic status of the different isolates belonging to L. guyanensis s.l. since the results showed substantial heterogeneity within this species complex. In conclusion, this study increases the number of available microsatellite loci for L. guyanensis species complex and raises fundamental biological questions. It confirms that microsatellite markers constitute good tools for population genetic studies on parasites of this complex.
