Abstract

This work aims to evaluate the antibacterial activity of lyophilized aqueous extract of Coriaria myrtifolia against twentythree bacterial strains belonging to twelve main genera, known to be involved in some pathologies and / or in the foodspoilage process: Bacillus sp., E. coli, E. hafnia, Enterococcus sp., Klebsiella sp,. Listeria monocytogenes, Pseudomonassp., Salmonella sp., Serratia sp., Shigella sp., S. aureus and Streptomyces sp. To achieve this goal, the disk diffusionmethod was used.The study revealed that C. myrtifoliaâ€™s aqueous extract is active against most of the tested strains and that activity isproportional to its concentration. The intensity of inhibition depends on the extractâ€™s concentration on one hand and on thebacterial species tested on the other hand.

Highlights

The infectious diseases induce more than 17 million deaths every year throughout the world from which more than half are registered in Africa [1]
We evaluated the antibacterial activity of lyophilized aqueous extract of Coriaria myrtifolia against twenty three Gram positive and Gram negative bacterial strains involved in several pathologies and / or implicated in the process of food spoilage
The results indicate that the aqueous extract has a dose-dependent antibacterial activity, because the inhibition is proportional to the extract’s concentration and that the bacterial sensibility varies from a tested strain to another one

Summary

Introduction

The infectious diseases induce more than 17 million deaths every year throughout the world from which more than half are registered in Africa [1]. They constitute an important concern of the public health because of their frequency and gravity [2]. Throughout the world and especially in Morocco, medicinal plants play an important role in therapy, in both urban and rural areas and are an inexhaustible source of new antibacterial agents. To check better the bacterial infections, it is urgent to highlight new effective antibacterial agents and it's in this context that this work is considered
