  1. Abbreviations: CL colistin, TG tigecycline, AMK amikacin, FEP cefepime, CAZ ceftazidime, PTZ piperacillin-tazobactam, AMS ampicillin/sulbactam, R resistant, S sensitive, I intermediate
  2. aThe MICs of tigecycline were interpreted according to the European Committee on Antimicrobial Susceptibility Testing breakpoint for Enterobacteriaceae spp. (MIC > 2 mg/L as resistant)
  3. The MICs of the other tested antibiotics were interpreted according to the Clinical and Laboratory Standards Institute (CLSI) guidelines
