Investigation of the Antibacterial Activity of Syzygium aromaticum Essential Oils

Abstract

In this study, the antibacterial activity of Syzygium aromaticum commercial essential oils against eight different clinical bacteria was investigated. Five different commercial essential oils, the research material, were obtained from the market. Proteus mirabilis, Shigella dysenteriae, Serratia marcescens, Pseudomonas aeruginosa, Staphylococcus haemolyticus, Staphylococcus caprae, Staphylococcus epidermidis and Staphylococcus aureus were used as clinical bacteria in the study. Antibacterial activity of commercial essential oils was determined by disk diffusion and Minimum Inhibition Concentration (MIC) tests. Disc diffusion findings obtained from essential oils against clinical bacteria were evaluated by comparing them with findings from various antibiotics. By considering the results of disk diffusion, the MIC values of three commercial oils were determined. When the results of the research were evaluated in general, two different commercial essential oils of Syzygium aromaticum species were found to be more effective than antibiotics against tested bacteria. In the next stages of the research, it is planned to determine the chemical components of commercial essential oils by GC-MS analysis and to demonstrate the effectiveness of essential oils on bacterial cells by electron microscopy.
