ABSTRACT

Antimicrobial resistance (AMR) has emerged as a major global health challenge and calls for alternatives to antimicrobial agents. Essential oils (EOs) originates from various plant parts as hydrophobic secondary metabolites. Essential oils are known to contain bioactive compounds with antimicrobial activities. This research study assesses and compares the antibacterial activity of Ylang Ylang (Cananga odorata), Oregano (Origanum vulgare), and Frankincense (Boswellia spp.) essential oils against gram positive bacteria; Staphylococcus aureus. The antibacterial activities of the essential oils were determined by the disk diffusion method. Essential oils were diluted at three concentrations (pure, 1:1, 1:10 v/v) and tested against S. aureus cultured on Mueller-Hinton agar plates. Inhibition zone diameters were measured to determine antimicrobial efficacy. The study revealedvarying degrees of antibacterial activity among the essential oils. Oregano showed the highest antibacterial activity against S. aureus followed by Ylang Ylang and Frankincense among the tested essential oils. The antibacterial effect of all the essential oils assayed followed a dose-dependent response. The essential oils all showed antibacterial efficacy, with Oregano oil showing the most antibacterial potential.
