Özet: In the present time, drug resistance in microbes is a very serious problem. Essential oils and other extracts of plants have evoked interest as sources of natural products. They have been screened for their potential uses as alternative remedies for the treatment of many  ailments. In the present study, the in vitro antibacterial activity of the essential oils from ten aromatic plants Thymus fontanesii, Thymus vulgari,Mentha pulegium, Eugenia caryophyllata, Origanum vulgare, Laurus nobilis, salvia, Geranium, Lavender and Cinnamomum aromaticum was investigated. The oils compositions were characterized by gas chromatography/mass spectrophotometrical analyses. The antibacterial activity of these oils were tested against seven pathogenic bacteria: Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Staphylococcus aureus  oxaR ATCC 43300, Staphylococcus aureus oxaS ATCC 25923, Staphylococcu  aureus ATCC 33862, Bacillus cereus ATCC 11778, Bacillus subtilis ATCC 6633; by using the agar incorporation method  to determine the Minimum Inhibitory Concentration (MIC) of each oil. The results have shown a greater antibacterial effect of all essential oils samples against Gram positive than the Gram negative bacteria. Pseudomonas aeruginosa was the only bacterium not susceptible to Laurus nobilis, salvia, geranium, lavandre,and  Mentha pulegium oils. The highest and broadest activity was shown by Cinnamomum aromaticum oil. These results suggest that these essential oils may be alternative natural source medicine to prevent and treat many bacterial diseases.
