Evaluation of the Bacteriostatic and Bactericidal Activity of Essential Oil of Thymus Satureioides

Essential oils have significant antimicrobial activities and can successfully replace antibiotic s that show their inefficiencies against resistant microorganisms [1]. The objective of this study is to evaluate the antibacterial activity of essential oils extracted from the leaves and flowering tops of Thymus satureioides against three gram-negative bacteria (Escherichia coli, Acinetobacter baumannii and Enterobacter cloacae) and two gram-positive bacteria (Bacillus cereus and Staphylococcus aureus). The extraction is carried out by hydrodistillation using a Clevenger-type apparatus with an average yield of 3.4%. The antibacterial activity is highlighted by the diffusion method on agar medium. A Strong inhibitory activity against bacteria isolated was recorded. However, the bactericidal activity is remarkable against all strains tested except Bacillus cereus.
