Neighbor-joining trees based on the analysis of partial sequences of hsp70, icd and mpi for L. (Viannia) species, indicating the identity of IOC/3645 and IOC/L3746 with L. lindenbergi. Bootstrap test (1000 replicates) was performed and values above 70% are shown. The trees are drawn to scale. The evolutionary distances were computed using the number of differences method [8]. GenBank accession numbers for each sequence are presented before the name of the species corresponding to each branch.
