THE PREVALENCE OF RESISTANCE TO 15 ANTIMICROBIAL DRUGS IN PSEUDOMONAS AERUGINOSA RECOVERED FROM PATIENTS IN TEHRAN, Iran

Article excerpt

Background: Pseudomonas aeruginosa is an opportunist patho- gen which causes different infections especially in patients with impaired immunity.

Methods: In the three-month period in spring of 2013, all the clinical isolates of P. aeruginosa were studied from the as- pect of resistance to 15 antimicrobial drugs by the means of disk diffusion method using Rosco company disks (Den- mark) in the laboratory of Pars Hospital in Tehran, Iran.

Results: A total number of 55 P. aeruginosa isolates were re- covered from different clinical samples of hospitalized pa- tients (27.3%) and outpatients (72.7%). Totally 54.5% of the- se patients were male and most of them were at the age of 45 or above (81.5%). Most of the isolates were collected from sputum (40%), urine (38.2%) and wound and abscess (12.7%). Among the studied antibiotics, the lowest level of resistance was documented to colistin (3.7%). Resistance to meropenem and piperacillin-tazobactam were also low (22.6% and 24.1%, respectively). Resistance to ceftriaxone, amikacin, ceftazidime, ciprofloxacin, gentamicin and tobra- mycin were detected in 38. …
