Abstract

Resistance of H.pylori against METRONIDAZOLE is increasingly appeared in reports of investigators of gastric infections. So that, seeking to find more effective anti-helicobacter drugs is a necessity.In this study, inhibitory effect of the P. aeroginosa-produced substance on H. pylori growth was determined using two methods, Cross-streak and Well-diffusion Only two out of 37 P. aeroginosa isalates were able to inhibit H. pylori growth which one of them was chosen for further investigation. Its antibacterial activity was tested on 31 isolates of H. pylori consisting 27 metrondazole-sensitive and 4 METRONIDAZOLE-resistant isolates. The inhibitory substance was enable to kill both metrondazole-sensitive and resistant isolates of H. pylori. The substance could also inhibit the of several other bacteria including E.coli, Salmonella sp., Klebsiella sp., S. aureus and a gram positive bacilli. While the inhibitory effect of the substance had no change at 40c for 30 days, its effect substantially reduced by treating at 600c for 15 minutes. Treatment of substance at 600c (30 min). 80˚c and 100˚c (15 & 30min), and freezing (-20˚c) and melting (37˚c) inactivated its inhibitory effect completely. Treatment with trips in also could inactivate it. Thus P. aeroginosa-produced substance, probably is a protein and may be classified in bacteriocin group.
