  1. SXT, sulfamethoxazole; CIP, Ciprofloxacin; GEN, Gentamicin; CAZ, Ceftazidime; CSL, Cefoperazone/sulbactam; CTX, Cefotaxime; IPM, Imipenem; PIP, Piperacillin; TGC, Tigecycline; MDR: Multidrug-resistant; XDR: Extensively drug-resistant.
  2. MDR (Multidrug-resistant): Non-susceptible to ≥ 1 agent in ≥ 3 antimicrobial categories. In this study, defined as resistant to 3 or more antibiotic classes with inhibition zone diameter ≤ 14 mm.
  3. XDR (Extensively drug-resistant): Non-susceptible to ≥ 1 agent in all but ≤ 2 antimicrobial categories. In this study, defined as resistant to all tested antibiotics except 1–2 categories.
  4. Resistance breakpoint: Inhibition zone diameter ≤ 14 mm was considered resistant.
