Phylogenetic tree based on the 9 SNPs selected for SCGs. Model-based neighbour-joining tree based on the 9 SNPs resolved of the 75 M. tuberculosis complex isolates and the reference strain analysed into the different SCGs. Numbers designate each SCG and Spoligotyping families are indicated by a different colour detailed in the legend. The SNP lineages that belong to the three “major genetic” groups based on combination of two alleles at katG463 and gyrA95 are also highlighted. The scale bar indicates the number of SNP difference.
