Unrooted maximum likelihood (ML) tree based on Sudanese L. donovani diplotypes across ten loci (13 kb in total). Only samples with corresponding microsatellite profiles were included. Eight coding and two pseudo-genes were analysed. ML bootstraps are given in bold, those not in bold are from a distance based (F84 + Gamma model) neighbor-joining analysis of the same dataset. Canine strains are indicated. Sudanese strains from 1993 (dark blue), 1997 (pale blue) 1998 (yellow) and 2001 (red) are labelled.
