The results of antimicrobial susceptibility of A. baumannii to the antibiotics investigated in this study. Overall, piperacillin/tazobactam, meropenem, and ciprofloxacin were the most commonly resistant antibiotics (100%). The two most effective antibiotics were colistin (84.5%) and amikacin (9.25%). SAM: Ampicillin-sulbactam; TZP: piperacillin/tozabactam; CAZ: Ceftazidime; FEP: cefepime; MEM: Meropenem; GM: Gentamicin; AN: amikacin; CIP: ciprofloxacin; SXT: Trimethoprim-sulfamethoxazole; and CL: Colistin
