The inhibitory effects of Thymus vulgaris essential oils were screened against Coliform spp, Pseudomonas spp, Saccharomyces cerevisiae (EC1118), Zygosaccharomyces bailii (DSM 70492) and Lactobacillus plantarum (DSM2601) by agar well diffusion method. Results obtained in thisstudy revealed that the essential oils of Thymus vulgaris posses a weak antibacterial effect against the tested microorganisms with small inhibition zones ranged between 0 and 4 mm. This activity was dose independent. Z. baillii was more susceptible to T. vulgaris essential oils, while Coliform spp was more resistant comparing to other tested microorganisms.
This study contributes to the existing literature and the scientific justification to the use of this plant in herbal medicine for the treatment of diseases of microbial origin and also introduces it as a potential candidate for drug development for the treatment of infectious diseases caused by these pathogens.
