Distribution of single nucleotide variants (SNV) throughout the genome. The detection of SNV was performed using the genome of ATCC13950 as the reference genome. Numbers on the upper right-hand side for each strain indicate the number of SNV as a scale. Regions surrounded by the bold and dashed lines indicate the common regions (b, e, h) and group- or subgroup-specific hypermutated regions (a, c, d, f, g, i, j), respectively
