Isolation of Ps. aeruginosa and study of resistance to some antibiotics and ability to pyocins production.

Abstract

The study involved the isolation and identification of Pseudomonas aeruginosa , thirty four (34)isolates obtained from (77)samples that were collected from patients attending Kirkuk General Hospital and (2) isolates obtained from (33) samples that were collected from hospital environment and (24) isolates were collected from Kirkuk City environment. The results demonstrated that the pathogenic isolates were resistant to Cefazolin and Carbenicillin by(97.22)%, where as isolates from Kirkuk City environment were resistant to Cefazolin , Carbenicillin and Cefatoxim by (100% , 95.5% , 91.6%) respectively. The results revealed that in Psudomonas aeruginosa the dominant pattern of multiple antibiotic resistance were (PY,CZ,CTX,CN,TOB) The results obtained showed that one isolates has inhibitory activity against Staphylococcus aureus . This isolates could possibly be as one of the pyocin producing isolates without using any stimulators.
