Determinación la actividad antimicrobiana del aceite esencial de eucalyptus globulus,frente a Staphylococcus aureus.

Abstract

Introduction: Preliminary studies using various plant extracts have shown inhibitory properties against diverse microbial agents. Eucalyptus globulus, with its medicinal applications ranging from headache relief to cold treatment, presents an opportunity for harnessing the potential of essential oils and expanding the understanding of their antimicrobial properties against bacteria, particularly Staphylococcus aureus. Objective: This research aims to determine the antimicrobial effects of Eucalyptus globulus essential oil on Staphylococcus aureus. Methodology: The essential oils were extracted using the steam distillation technique, obtaining them in high concentrations. Inhibitory concentrations were measured at percentages of 100%, 75%, 50%, 25%, and 12.5% against a strain of S. aureus. Inhibition measurement employed the agar diffusion method, utilizing disks impregnated with varying concentrations of essential oils, which are obtained from the plant under study. Results: This approach facilitated the determination of inhibition zones for each concentration, effectively demonstrating the antimicrobial impact on Staphylococcus aureus bacteria. Conclusion: It can be concluded that S. aureus bacteria exhibit sensitivity to Eucalyptus globulus essential oil at concentrations above 75%, being more effective when the oil is refined.
