Numbers of ABU and CA-ABU E. coli isolates resistant to each antibiotic included in the antibiotic screening. The “none” category indicates isolates that were susceptible to all antibiotics included in this study. There were no statistically significant differences between the numbers of resistant isolates in the ABU and CA-ABU groups for any antibiotic. AMP, ampicillin; CAZ, ceftazidime; CEF, cephalothin; CFZ, cefazolin; CIP, ciprofloxacin; CRO, ceftriaxone; FEP, cefepime; FOX, cefoxitin; GEN, gentamicin; LEX, cephalexin; MEM, meropenem; NIT, nitrofurantoin; NOR, norfloxacin; SXT, trimethoprim-sulfamethoxazole; TMP, trimethoprim; TOB, tobramycin; and TZP, piperacillin-tazobactam.
