Abstract

Introduction: Staphylococcus aureus is an important etiological agent of skin and soft tissue infections. Due to the increasing resistance of this bacterium to antimicrobial agents, treatment of staphylococcal infections remains a great challenge for clinicians and requires an alternative treatment options. Objective: The aim of the study was to determine the antimicrobial activity of essential oils: caraway (CEO), patchouli (PEO) and geranium (GEO) against S. aureus strains isolated from skin lesions in the course of staphylococcal skin infections. Methods: The antibacterial activity of essential oils was tested using the dilution method in Mueller-Hinton broth. Results: The antimicrobial effect of CEO, PEO and GEO was observed. The highest antimicrobial activity showed PEO (MIC = 1.7±0.8 µl/ml), the lower was observed for GEO (MIC = 5.4±2.0 µl/ml) and CEO (MIC = 18.8±10.3 µl/ml). Conclusion: All tested essential oils showed antibacterial activity against S. aureus strains isolated from skin lesions of patients with staphylococcal skin infections. Application of the CEO, PEO and GEO can become an alternative method of treatment of staphylococcal infections, but further microbiological tests and clinical trials should be assessed.
