FIG 3.

Distribution of acquired resistance genes and plasmids within 63 multidrug-resistant E. coli strains. Antimicrobial susceptibility profiles (R, resistant; blank, susceptible) and presence (black)/absence (white) of resistance genes and plasmids for each isolate are shown. SAM, ampicillin-sulbactam; TZP, piperacillin-tazobactam; CRO, ceftriaxone; FEP, cefepime; IMP, imipenem; EPM, ertapenem; GEN, gentamicin; AMK, amikacin; CIP, ciprofloxacin; LVX, levofloxacin; SXT, trimethoprim-sulfamethoxazole; MIN, minocycline. Yellow shading, H30Rx isolates; green shading, H30R1 isolates.
