a
CZ, cefazolin; GEN, gentamicin; AM, Ampicillin; CTX, cefotaxime; CIP, ciprofloxacin; FEP, cefepime; FOX, cefoxitin; CRO, ceftriaxone; TZP, piperacillin/tazobactam(E‐test); PIP, piperacillin; IPM, imipenem(E‐test); MEC, meropenem(Etest); AMK, amikacin; LVX, levofloxacin; CAZ, ceftazidime; ATM, aztreonam; PB, polymyxin B(E‐test).
b
MICs were determined by the BD PhoenixTM‐100 automated bacterial identification susceptibility analyzers system or the E‐test. Where a “>“ sign is present in an entry with two values, the sign applies to both values in the entry. The second MIC refers to the second drug in the compound.
