Gentamicin (GEN), Amikacin (AK), Imipenem (IPM), Meropenem (MRP), Cefazolin (CZ), Cefuroxime (CXM,), Cefoxitin (FOX), Cefotaxime (CTX), Ceftazidime (CAZ), Cefepime (CPM), Ampicillin (AMP), Aztreonam (AT), Amoxicillin-Clavulanic Acid (AMC), Piperacillin-Tazobactam (TZP), Fosfomycin (FO), Ciprofloxacin (CIP), Trimethoprim-Sulfamethoxazole (SXT), Chloramphenicol (C), Tetracycline (TE), Tigecycline (TGC), Nitrofurantoin (NIT), and Colistin (CL). R resistant, I intermediate resistance, S susceptible
^aResistance rates (%) are calculated as the proportion of isolates that are R, I, or S to the total number of isolates (n = 100), multiplied by 100
^bFor CPM, the CLSI categories include R, SDD (sensitive dose-dependent), and S
