FREQUENCY AND SUSCEPTIBILITY

Objectives: The aim of this study was to isolate Pseudomonas aeruginosa as causative agent of pus and to
determine the drug sensitivity of the identified organisms.
Material and Methods: Material and Methods: Material and Methods: Material and Methods: Material and Methods: In this study a total of 20 P. aeruginosa-positive pus cultures were obtained out of 272 and
tested for ten antibiotics (Gentamicin, Imipenem, Amikacin, Norfloxacin, Tobramycin, Ciprofloxacin, Aztreonam,
Cephalosporin, Cefotaxime, Sulzone.
Results: Results: Results: Results: Results: The highest rates of resistance were found for Cephradine (90%), Cefotaxime (75%), Aztreonam (55%),
Gentamicin (40%), Sulzone (35%), Tobramycin (30%), Amikacin and Ciprofloxacin (25% each), while low resistance
was seen in case of Imipenem (10%), Norfloxacin (5%) as compare to other antibiotics.
Conclusion: Conclusion: Conclusion: Conclusion: Conclusion: Isolates of P. aeruginosa from pus showed highest sensitivity (90%) to imepenem while maximum
resistance was showed to Cephradine (90%) and Cefotaxime (75%).
