Effect of Teucrium polium L extract on E.coli growth by poisoned food technique , disc diffusion and approach of the disc diffusion methods

Abstract

Escherichia coli is a facultative anaerobic Gram-negative bacterium from the Enterobacteriaceae family that colonizes the gastrointestinal tract. Teucrium polium L is a medicinal plant growing in the western Mediterranean region. Different studies aim to determining the stages at which E. coli growth is more sensitivity to certain concentration of medicinal plant like Alcoholic and aqueous extract of Teucrium polium and their effective concentration based on the zone of inhibitions on plate that previously inoculate with Escherichia coli and the plant extracts and utilized to monitor growth of bacteria.
