In-Vitro Antibacterial Properties of Sage (Salvia officinalis) Ethanol Extract against Multidrug Resistant Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa and Klebsiella pneumoniae

Abstract

Background: Due to excessive consumption of synthetic drugs, drug resistance rate of pathogenic bacteria is increasing and the need to find new compounds is necessary. The aim of this study was to investigate the antibacterial effect of ethanol extract of, sage to the four species of common pathogenic bacteria resistant to multiple drugs in vitro such as: Staphylococcus aureus (50 strains), Escherichia coli (50 strains), Pseudomonas aeruginosa (50 strains) and Klebsiella pneumonia (50 strains).
