Aims; the aim of this study was evaluation of 29 hydro-alcoholic extract of different medicinal plants on Escherichia coli and Staphylococcus aureus.
Material and methods; In this study, the antimicrobial effects of hydro-alcoholic extracts were obtained on the bacteria E. Coli and Staphylococcus aureus in a culture medium Mueller-Hinton agar diffusion method using paper discs 6 mm method in accordance with the instructions Bauer and Kirby and Mark wells method.
Finding; The results showed that the most effective hydro-alcoholic extracts of medicinal plants on The diameter of inhibition zone of Staphylococcus aureus was Thyme, Myrtus and Chamomile, and on the diameter of the inhibition zone of E. coli was Thyme, Myrtus and Rosemary. In addition, it was found that the environmental impact was less effective on the antimicrobial activity of hydro-alcoholic extracts of medicinal plants like Myrtus and Thyme but it was more effective on chamomile. The weakest plants in the diameter of the inhibition zone of both types of bacteria studied was Smyrnium, Fumaria officinalis, hyssop, wormwood, thyme and oregano. There was significant effect between anti-microbial hydro-alcoholic extracts of medicinal plants in two six-millimeter disc and plate-making methods as the diameter of the inhibition zone of both bacteria in the wells of investment was more than paper disc method.
Conclusion; In accordance with the results of this project and also increasing resistance to antimicrobial synthetic materials, some medicinal plants like thyme, myrtus and rosemary can be as effective in destroying some bacteria including E. coli and Staphylococcus aureus.
