Keywords: Pseudomonas aeruginosa, antibiotic susceptibility, intensive care unit

Objective: Pseudomonas aeruginosa strains, which are widely found in hospital settings, are especially the most frequently isolated microorganisms in the intensive care unit. P. aeruginosa strains are the cause of infections which are usually difficult to treat, leading to increased morbidity and mortality. This study was aimed to retrospectively investigate the antibiotic susceptibilities of the P. aeruginosa strains isolated from the clinical samples sent to our hospital's Microbiology Laboratory.

Materials and Methods: Bacterial identification was done by standard biochemical tests and BBL Crystal E/NF (Beckton Dickinson, USA) system. Antimicrobial susceptibilities were evaluated by disc diffusion method on Mueller-Hinton agar according to the Clinical and Laboratory Standards Institute (CLSI) standards.

Results: Most of the isolates were recruited from urinary (52%) and respiratory (34%) tract samples. The highest rate of the isolates were obtained from the intensive care unit (53%). Susceptibilities to ciprofloxacin ceftazidime piperacilline/ tazobactam, and amikacin were found to be 48, 78, 80 and 83%, respectively.

Conclusion: Knowledge about the antibiotic resistance profiles of P. aeruginosa strains is important for rational antibiotic usage and infection control measures in hospitals.
