Abstract:
Carvacrol and thymol are two phenolic monoterpenes, which are formed during plant bacterial infections, showing antibacterial properties that might be beneficial for consumers and might support xenohormesis hypothesis. The antimicrobial activities of phenolic monoterpene-containing essential oils were demonstrated against avian strains of Pseudomona aureginosa, Escherichia coli, Bacillus subtillis and Staphylococcus aureus using disk diffusion assay, and with combinations of oils plus streptomycin or penicillin. Additionally, a bibliography research was performed. Thymol and carvacrol show antibacterial properties due to a membrane disruption, biofilm and motility reduction, and ATPases and efflux pump inhibition. Phenolic monoterpenes perhaps compose a direct xenohormesis.
