Antimicrobial effect of Methanolic and Acetonic of Zataria Multiflora, Capsicum Annum L. and Piper Nigrum L. extracts on Pseudomonas aeruginosa strains isolated from patients hospitalized in the burn Ward of Shahid Motahari hospital in Tehran

ABSTRACT

Background: Pseudomonas aeruginosa [P. aeruginosa] is one of the main causes of nosocomial infection. Burn patients are at high risk of acquiring this bacterium due to skin damage and their immune deficiency, and mortality rate in these infected patients is high [40-50 percent]. Therefore, due to antibiotic resistance of MBL containing strains in this bacterium, the aim of this study is to investigate the effect of methanol and acetone of Zataria multiflora, Capsicum annum L. and Piper nigrum L. on strains containing MBL in this bacterium
