Antibiosis resistant of Pseudomonas aeruginosa isolated from different clinical specimens

Abstract

Objective: Detection of antibiotic sensitivity of Pseudomonas aeruginosa isolated from different clinical specimens in Kirkuk, Iraq.Material and Methods: The present study included (3138) samples collected from different clinical specimens from outpatients and inpatients of both sexes with different ages who were attended Azadi Teaching Hospital/ Kirkuk during the period from October/2007 until May/ 2013. Results: From a total of 3138 Specimens, 1485 gave positive cultured and 1653 Specimens showed no bacterial growth, 319/3138 (10.17%) isolates were identified as P. aeruginosa. These isolates were identified according to morphological, cultural and biochemical characteristics. Wound and ear swab were important source for P. aeruginosa and isolated more frequently in inpatients than outpatients. The rate of isolation in females 169/319 (52.97%) was higher than males 150/319 (47.01%). Antibiotic susceptibility test of these isolates was performed, and the results showed that all Pseudomonas isolates (100%) were resistant to ampicillin, cephradin and trimoxazole, followed by gentamycin (97.3%), Amoxicillin (97.3), cephalexin (92.3%), neomycin (91.4%), nalidixic acid (89%), nitrofurantoin (87.5%), tobramycin (87.5%) and ciprofloxacin (84%), and the resistance to amikacin was (75%).Conclusions: P. aeruginosa is multiresistant isolated in a high frequency from wound swabs followed by ear swabs.
