  • a Includes one publicly available sequence of E. coli ST131.

  • b Publicly available sequence data for E. coli ST131.

  • c One isolate from Austria belonged to H31.

  • d The P values are comparing the prevalence of each antibiotic resistance gene among geographical regions. P values in boldface type represent statistically significant results.
