Temporal trends for resistance category prevalence and phylogroup distribution. Data are for 2000, 2003, 2006, and 2009; intervening points are interpolated. Resistance categories: ESC-RS, extended-spectrum cephalosporin-reduced susceptibility; FQ-R, fluoroquinolone resistant, ESC susceptible; FQ-S, fluoroquinolone susceptible, ESC susceptible. *, P < 0.05 for linear trend. (A) Relative prevalence of the three resistance categories among all SENTRY collection Escherichia coli isolates. (B) Measured relative prevalence of seven E. coli phylogroups (A, B1, B2, C, D, E, and F) among the 75 selected ESC-RS study isolates (17 to 20 per year). (C) Measured relative prevalences of seven E. coli phylogroups among the 80 selected FQ-R study isolates (20 per year). (D) Measured relative prevalences of seven E. coli phylogroups among the 79 selected FQ-S study isolates (19 or 20 per year). (E) Imputed relative prevalences of seven E. coli phylogroups within the overall SENTRY source population.
