LINK BETWEEN SOME VIRULNCE FACTORS GENES AND ANTIBACTERIAL RESISTANCE OF PSEUDOMONAS AERUGINOSA

The research was aimed to demonstrate the frequency of virulence factors genes (exoenzyme S and exotoxin A) express their relationship antibacterial resistance among Pseudomonas aeruginosa isolated from patients suffering otitis externa. results were revealed that only twenty one (32%) out 65 clinical ear swabs aeruginosa. According PCR amplification, 18 (85.7%) bacterial isolates expressed both toxins ( exoenzyme A). data get by real time experiments give higher percentage seen against Ceftazidime (90.5%) Gentamicin (88.5%).Only thirteen (61,90%) Multidrug (MDR) –Pseudomonas detected, two (9.5%) resist all 8 classes antibiotics considered as PDR, three (14.2%) seven which XDR.
