Study The Antibiotic Susceptibility Patterns Of Pseudomonas aeruginosa Isolated from Hospital Infections

Abstract

Out of 726 clinical specimens including wound burn, ear, pus swabs, sputum and urine, 272 isolates of Pseudomonas aeroginosa were detected by bacteriological and biochemical tests, 163 of these isolates were from females and 109 from males.
181of the isolates (66.54%) were pure isolates of P. aeruginosa, while 91 isolates (33.45%) of p. aeruginosa were found mixed with pathogenic bacteria, (76.9%) of these isolates were mixed with Klebsiella spp.
Antibiotic sensitivity test for p. aeruginosa was done by using Kirby Bauer disc diffusion method to6 kinds of available antibiotics, it appeared that p.
aeruginosa isolates were highly resistant to most of the antibiotics.P. aeruginosa isolates was found to be more resistant to aminoglycoside antibiotics:-
Amikacin,Gentamycin and ciprofloxacin (84.6%, 95.95%, 79.77%) respectively, and the highly resistance was to cephalexine showing 100% resistance followed by Ceftriaxon (96.32), surprisingly, Pipracillin showed a relatively higher sensitivity (47.79%).
