Characterisation of the antimicrobial effect of essential oils for equine veterinary medicine as a complementary therapy

Résumé

Background: Essential Oils (EOs) are a therapeutic adjunct to the emergence of antibiotic resistance due to their reported antimicrobial properties [1,2]. Objectives: The antibacterial and antiviral effects of some EOs from three different suppliers were investigated, considering EOs' volatility and hydrophobicity. Study design: In vitro experiments. Methods: After the chemical composition determination of selected EOs, their antimicrobial activity was characterised on pathogenic bacteria and viruses Seven EOs were selected for their interest in veterinary phyto-pharmacopoeia. Gas chromatography was used to identify and quantify their main compounds. Antibacterial activity was evaluated by determining the minimum inhibitory concentration (MIC) broth dilution against four bacterial (Gram positive and Gram negative) wildtype and resistant strains. Impedance measurement on equine dermal cells was used to evaluate the antiviral activity of EOs against equine herpesviruses (EHV) -1 and -4. Main limitation: No gold standard methods are available for EOs antimicrobial characterisation. Conclusions: Our study lays the scientific foundations for an evaluation of the in vitro effects of EOs to provide a better understanding of in vivo applications. Ethical animal research: Not required: analysis of microorganisms. Informed consent: Not applicable. Competing interests: None declared. Funding: IFCE (Institut Français du Cheval et de l'Equitation) and Fonds Eperon. References: [1] Maccelli A, Vitanza L, Imbriano A, Fraschetti C, et al. Satureja montana L.
