title: Regional genetic differentiation of Phlebotomus sergenti in three Moroccan foci of cutaneous leishmaniasis caused by Leishmania tropica.
abstract: Phlebotomus sergenti was identified morphologically in samples from three Moroccan foci of leishmaniasis caused by Leishmania tropica in the provinces of Azilal, Essaouira and Taza. Three primary mitochondrial DNA lineages were identified, and they could be markers for regionally distributed cryptic species. Greater mitochondrial diversity in Azilal indicated that this central province could have been the origin of dispersal of P. sergenti or the zone of secondary contact. All except one of the 21 mitochondrial haplotypes showed a marked regional distribution, and this indicates that vector control would not always be followed by rapid, long-distance reinvasion. Only mitochondrial haplotype SER18 was a putative marker for long-distance dispersal, for which there is no evidence of human assistance.
