↵a Loci are listed within each isolate group in descending order of allelic diversity, except for those loci that were excluded.
↵b Standardized worldwide collection from reference 23.
↵c Extended collection with isolates from worldwide origins, including the 90 isolates from reference 23. Because of their particular population structure, characterized by homogeneous clonal groups with horizontal gene transfers among them (15), M. prototuberculosis isolates were not considered for this analysis.
↵d 1, discriminatory subset of 15 loci; 2, subset of nine auxiliary loci. Table 1 gives alias designations of loci.
