    Abstract:
    Multilocus microsatellite typing (MLMT) was employed to compare strains of Leishmania donovani belonging to the MON-37 zymodeme (MON-37 strains) from Cyprus and Israel to MON-37 strains from the Indian subcontinent, the Middle East, China and East Africa as well as strains of other zymodemes. The MLMT data were processed with a distance-based method for construction of phylogenetic trees, factorial correspondence analysis and a Bayesian model-based clustering algorithm. All three approaches assigned the MON-37 strains to different distantly related genetically defined subgroups, corresponding to their geographical origin. Specifically, the Kenyan, Sri Lankan and Indian MON-37 strains were genetically closer to strains of other zymodemes from the same regions than to MON-37 strains from other areas. MON-37 strains from Cyprus and Israel were clearly different not only among themselves, but also compared to all the other MON-37 strains studied and could, therefore, be autochthonous. This study showed that the zymodeme MON-37 is paraphyletic and does not reflect the genetic relationship between strains of different geographical origin.
