Figure 4

A plot graph showing the genetic variability within PE_PGRS17 and PE_PGRS18. The plot shows the distribution of the 12/40 polymorphism and the other SNPs among 101 worldwide distributed tubercle bacilli isolates (98 tubercle bacilli sequenced in this study along with the sequences from M. tuberculosis reference strains H37Rv, CDC1551, and M. bovis reference strain AF2122/97). SNPs (relative to the M. tuberculosis reference strain H37Rv) are shown in colours other than orange, whereas grey background indicates the presence of a deletion. M. tbM. tuberculosis, M. afriM. africanum, M. capM. caprae, M. pinM. pinnipedii, STB-Smooth tubercle bacilli.
