*N = 187; MIRU, mycobacterial interspersed repetitive units; ETR, exact tandem repeats; HGDI, Hunter-Gaston diversity index; AV, allelic variants. †Boldface loci showed at least moderate discriminative power as defined by Sola et al. (23) and were the most promising loci. Other loci provided poor discrimination or were monomorphic.
