Prevalence and antibiogram pattern of pseudomonas aeroginosa strains isolated from various clinical specimens in Bandar Abbas,Iran

Introduction: The emergence of antimicrobial resistance at alarming rates has received a great deal of attention. Worldwide hospitals are facing with increasingly rapid emergence and spread of antibiotic resistant bacteria, among which pseudomonas aeroginosa is the most significant one. The aim of this study was to evaluate the susceptibility of 94 strains of pseudomonas aeroginosa to these antibiotics. Methods: In this experimental study, 94 non-repetitive isolates of pseudomonas aeroginosa from different clinical samples were collected. Susceptibility of each strain to 21 currently used antibiotics was determined by Kirby-Bauer method on Muller Hinton medium. Results: All of the strains (100%) were sensitive to imipenem. Among fluoroquinolones and aminoglycosides, ciprofloxacin and amikacin with 74.4% and 66.6% sensitivity were found to be the second and third most active agents, respectively. Conclusion: Several studies have been conducted on antibiogram profile of pseudomonas aeroginosa expressing different results. These differences may be due to diversity in distribution of different strains of this bacterium, kind, amount and duration of antibiotic therapy and also quality of disks manufactured by different companies.
