Heat map of the similarity matrix obtained from best reciprocal BLAST hits values (Pearson correlation). Colour shades indicate the percentage of correlation (1 = 100%): from red to yellow 0.9982 to 0.5370; from yellow to green 0.5370 to 0.0758. The groups found with SNPs analysis have been highlighted (black squares). Analysis of the colours illustrates three distinct macro-groups (blue square). Macro-group 1 containing isolates SNPs groups 1,10 and 9; macro-group 2 containing isolates SNPs group 2,3,4.5.6.9,10 and macro-group 3 containing isolates from SNPs groups 2,7, and 8. Noteworthy is the fact that macro-group 2 contains strains from both the other macro-groups, suggesting that the strains in this macro-group could be either ancestors or newly evolved strains
