Microsatellite-based neighbor-joining tree reveals genetic diversity among L. donovani from Sudan. DAS (1-proportion of shared alleles) distances were calculated. Branch colour indicates disease status: red - visceral leishmaniasis; green - post-kala-azar dermal leishmaniasis; blue - cutaneous leishmaniasis, pale blue - dispersed cutaneous leishmaniasis. Dog symbols indicate the presence of strains from canids, green circles indicate the presence of strains from Barbar El Fugara, and country codes are indicated in the yellow boxes: SD - Sudan, IN-India, KE-Kenya, ET-Ethiopia, PT-Portugal, FR-France, ES-Spain. Values indicate % bootstrap support across 1000 pseudo-replicates.
