Patterns of evolutionary descent among multilocus sequence typing (MLST) types of Cryptosporidium hominis, as revealed by eBURST analysis of allelic data. The numbers for each MLST type represent the sequence type at each of the eight MLST loci, in the following order: gp60, CP47, Mucin1, CP56, RPGR, MSC6-7, DZ-HRGP, and HSP70. Blue dot, primary founder; yellow dots, subgroup founders. The size of each dot is proportional to the number of specimens of the sequence type. The three MLST types of the gp60 IgA27 subtype did not cluster in this diagram. See Fig. 1 legend for the origins of the specimens.
