Antimicrobial Activity of the Aqueous Extract of Mint Plant

Abstract

In the present study, an antimicrobial activity of the Aqueous extract of Mentha species was assessed using both well diffusion and microdilution method in multi-well micro-titer plates. Mint extract investigated for its antibacterial activity against seven selected pathogenic bacteria: Bacillus fastidiosus, Staphylococcus aureus, Proteus mirabilis, Proteus vulgaris, Salmonella choleraesuis, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae and Serratia odorifera. Menth extract at different concentrations (1:1, 1:5, 1:10, and 1:20) was active against all tested bacteria except for S.aureus, and the highest inhibitory effect was observed against S. mutans using the well diffusion method. Antibacterial activity of Aqueous extracts of selected commonly used Mint were screened against multi drug resistant bacteria ,which concludes that their extracts can be used against multi drug resistance bacteria capable of causing both nosocomial and community acquired infections.
