Figure 2. Virulence traits (top) and antimicrobial resistance phenotypes (bottom) of Escherichia coli clonal group A (CGA) isolates versus non-CGA controls. Percent of isolates positive for each virulence trait (top) or resistance phenotype (bottom) is shown by pink bars to left of midline (for CGA) or blue bars to right of midline (for controls). No isolates were positive for bmaE (M fimbriae), or resistant to amikacin, aztreonam, cefepime, ceftazidime, ertapenem, imipenem-cilistatin, nitrofurantoin, piperacillin-tazobactam, or ticarcillin-clavulanate. p value symbols at right of each chart, from Fisher exact test or χ2 test, are for significant differences between CGA and non-CGA. *, p < 0.05; **, p ≤ 0.01; ***, p ≤ 0.001.
