  1. aConsensus identification based on combination phenotypic (API20E/ID32E) and 16S rRNA and rpoB gene sequencing
  2. bDisk diffusion testing using the following antibiotics: ATM aztreonam, CAZ ceftazidime, CIP ciprofloxacin, IMP imipenem, TGC tigecycline, C chloramphenicol, D doxycycline, G sulfisoxazole, GM gentamicin, K kanamycin, SAM ampicillin/sulbactam. R resistant, I intermediate, and S sensitive phenotypes were determined based on CLSI criteria
  3. cESBL phenotypes: YES – ESBL detected, NO – no ESBL present, N/D – ESBL presence could not be determined based on the E-test or double disk diffusion assay
