Fatima Zahra Sadiki, Mostafa El Idrissi, Mohammed Sbiti
This work aims to study the antibacterial activity of the essential oil of aerial parts of Thymus hyemalis in order to search for new bioactive products of natural origin with antibacterial activities. Five bacterial strains of clinical origin were tested: Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Pseudomonas aeruginosa and Staphylococcus aureus. Two methods have been used to evaluate the antibacterial effect of this essential oil: the disc diffusion method and the macrodilution method which aims to determine the minimum inhibitory concentration. Our results indicate that Thymus hyemalis oil has shown significant activity against the Escherichia coli strain, and is characterized by a bactericidal action against the inhibited germs.
