Study of Antibiotic Resistant Genes in <i>Pseudomonas aeroginosa</i> Isolated from Burns and Wounds.

Abstract

were collected from 200 patients with wounds and burns. Most cases were isolated from 23 (74.19%) and 8 (25.80%) wound and burn swabs, respectively. Antibiotic sensitivity was tested on all isolates against 17 antimicrobial agents. The obtained results revealed a high resistance rate to gentamicin, trimethoprim, amikacin, and amoxicillin, and a low resistance rate was observed to ceftazidime, tobramycin, levofloxacin, cotrimoxazole, ciprofloxacin, and aztreonam. Regarding antibiotic resistance, mexB, mexR, and oprD genes were observed in three isolates, in which mexB and mexR were detected in two isolates, and only one isolate carried mexA gene.
