Use of medicinal plant extract against bacteria could reduce the use of antibiotics. One of these herbs is Zingiber officinale rose and the other one is Myrtus communis that have been reported in this paper.  In this study, we tried to show application of Myrtus communis L and dry and fresh Zingiber officinale rose (alcoholic extracts) on growth inhibition of some bacteria. Microorganisms used in this study were selected according to their pathogenicity including Staphylococcus aureus (ATCC 25923), Bacillus cereus (ATCC 10876 & NCTC 7464) and Listeria monocytogenes. Alcoholic extract of Myrtus communis and Zingiber officinale rose were prepared and concentrated up to 70% of initial weight. The fresh Zingiber officinale rose extract had the most restrains effect (attended to minimal restrain) for 42.6 milligrams of Listeria with the percentage of 9.1 millimeters of corona. There is no any restraining effect of fresh Zingiber officinale rose on these bacteria. For Staphylococcus aureus and Listeria monocytogenes, the Myrtus communis herb had a more restraining effect than fresh Zingiber officinale rose. In conclusion, ginger extract can effectively kill pathogenic bacteria.
