Figure 2. Classification of Leishmania donovani and L. infantum isolates constructed by using microsatellite data with parsimony in PAUP (Sinauer Associates Inc., Sunderland, MA, USA). Numbers at branch points are bootstrap values compiled by using 100 replicates. Isolates formed geographically based groups (circled). Sri Lanka isolates L59, L60, L75, L78, and L80 are indicated. The tips of other branches are from a dataset of other previously analyzed isolates, including all those identified as L. donovani or L. infantum and isolates from the Indian subcontinent (10).
