Fig 1. Estimated population structure for the 84 Leishmania infantum strains isolated from Sicily (south Italy), as inferred by STRUCTURE on the basis of microsatellite profiles.

Each individual is represented by a single vertical line. Each color represents one population: green for POP-A and red for POP-B. The length of the colored segment shows the strain’s estimated proportion of membership (Q) in that population. Sample numbers are according to Table 1.
