Aim: This study aims to investigate antibiotic resistance rates of 110 Pseudomonas aeruginosa strains isolated from nosocomial infections.
Material and Methods: Pseudomonas aeruginosa isolates were identified by conventional methods. According to the standards of Clinical and Laboratory Standards Institute, antibiotics susceptibility tests were performed by Kirby-Bauer disk diffusion method. Imipenem, meropenem, ceftazidime, cefepime, aztreonam, piperacillin/tazobactam, amikacin, gentamicin, tobramycin, netilmicin, ciprofloxacin, cefoperazone/sulbactam and colistin sensitivity was investigated.
Results: Pseudomonas aeruginosa isolates were most susceptible to antibiotics respectively, colistin (100%), ceftazidime (97%), cefepime (96%), amikacin (94%), piperacillin (94%) and ciprofloxacin (92%). There was no statistical difference for activity between colistin and ceftazidime, cefepime antibiotics. Ceftazidime and cefepime were found significantly more active than carbapenems (p:
