Fatima Zahra Sadiki, Mostafa El Idrissi, Mohammed Sbiti
Pages: 59-64


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.
