The main objective of this work is to evaluate the antimicrobial activity of the essential oil of oregano (Origanum vulgare). Origanum vulgare is an aromatic plant, widely distributed in Morocco and widely used by the Moroccan people in order to its medicinal characteristics. Origanum vulgare is collected from Ouazzane City in the North of the Kingdom. The essential oil of oregano is obtained by hydro-distillation in a Clevenger-type apparatus with highest yield leaves up to (2.34%). The inhibitory activity of the essential oil of oregano is not the same against all tested strains (Escherichia coli ATCC 25921, Klebsiella pneumoniae, Enterobacter cloacae, Pseudomonas aeroginosae ATCC 27853, Acinetobacter sp, Staphylococcus aureus ATCC 25923). However, the bactericidal activity was remarkable against all strains tested.
