Main Article

Figure 1

The allelic diversity of each VNTR loci (h) and the discriminating power according to the Hunter-Gaston index (HGI) were calculated by using this algorithm (32). MIRU-VNTR, mycobacterial interspersed repetitive unit–variable number of tandem repeats; xi, the frequency of allele i; n, total no. of strains in the scheme; N, total number of strains in the typing scheme; s, total no. of different MIRU-VNTR patterns, nj, no. of strains belonging to the jth type.
