Potential effect of antimicrobial agents against Staphylococcus aureus and Pseudomonas aeruginosa strains from patients with skin infections

Abstract

The present study is designed to investigate S. aureus and Pseudomonas aeruginosa bacteria isolated from wound and burn patients in Thi-qar province and detection of the optimal antibiotic. All S. aureus isolates were tested for their susceptibility to thirteen antibiotics, all S. aureus isolates 100% were resistant to ß-lactam antibiotics to both Ampicillin, penicillin, 91.5% to both cefoxitin, oxacillin, 89.1% to both Vancomycin, ciprofloxacin , iodine and ethanol has reduced 100% the growth of S. aureus and Tobramycin , 78.3% to tetracycline ,67.5% Netilmicin, 64.8% Clindamycin, 59.4% Erythromycin, 45.9% to both Amikacin , Ciprofloxacin and 29.7%Gentamicin while Pseudomonas aeruginosa isolates were tested for their susceptibility to twelve antibiotics, all isolates 100% were resistant to both Trimethoprim , Amikacin, Piperacillin, Ticarcillin, Aztreonam and Gentamicin ,95.2% cefotaxime , 85.7%Colistin sulphate, 80.9% to both Netilmicin, Ceftazidime, 76.1% Ciprofloxacin and 28.5% Imipenem. It concluded from the present study that all isolates of S. aureus were resistant to B-lactam antibiotics and Ciprofloxacin must be the best antibiotic that used against this microorganism.
