Antibacterial Activity of Aqueous Extracts of Artemisia species against some Pathogenic Bacteria
ABSTRACT: The present study was lead with a view to evaluate the antibacterial potentials of aqueous extracts of Artemisia species against human pathogenic bacteria: Escherichia coli (E.coli), Pseudomonas aeruginosa (Ps. aeruginosa) , Staphylococcus aureus (Staph. aureus) and Enterococcus faecalis (Entero. faecalis) by two methods, first method was minimum inhibitory concentration (abbreviation: MIC) and sound method was minimum bactericidal concentration (abbreviation: MBC). Three crude plants extracts namely Artemisia monosperma, Artemisia cina and Artemisia argyi were found to show potential antibacterial properties against the isolated human pathogenic bacterial isolates. The results of MIC and MBC values of Artemisia monosperma for Enterococcus faecalis strains were at least concentration almost 2.3 and 4.1 mg/ml respectively, while MIC and MBC of Artemisia cina for Escherichia coli were highest concentration 3.9 and 4.9 mg/ml respectively. Moreover, MIC and MBC values for Pseudomonas aeruginosa, Staphylococcus aureus and Enterococcus faecalis strains was correspondent with MIC and MBC values of Escherichia coli for aqueous extracts of Artemisia species meanwhile it is Artemisia cina which showed maximum activity against Escherichia coli. Among the Artemisia species tested, Artemisia cina showed the most promising result. Form these results prove the antibacterial potential of the plants and hence provide support for the use of them in traditional medicine.
