E. coli ST131 comparison. Maximum likelihood tree of the 26 study ST131 isolates and 312 global ST131 isolates mapped against the reference strain E. coli NTCC13441. Coloured rings from the inside out indicate country of origin, fimH type, CTX-M type and study isolates (black), respectively. Branches coloured blue indicate the major clusters of Thai isolates from this study (C2; 11 o’clock in the figure) or Thai isolates from this study clustered with phylogenetically related isolates from other countries (C1; 5 o’clock in the figure). Scale bar indicates 100 SNPs
