摘要
This study aimed to determine the antimicrobial activity of 247 essential oil combinations against the reference strains of wound pathogens. Essential oil combinations were investigated for antimicrobial activity against five pathogens. The minimum inhibitory concentration (MIC) assay was used and the fractional inhibitory concentration index (sigma FIC) calculated to determine interactions between selected oils. Twenty-six combinations displayed broad-spectrum antimicrobial activity against all five reference strains and several displayed synergy against more than one pathogen. The combination of Santalum austrocaledonicum (sandalwood) with Commiphora myrrha (myrrh) displayed noteworthy antimicrobial activity against all five reference strains and synergy against four (MIC values 0.03-1.00 mg/ml and sigma FIC values 0.19-1.00 mg/ml) pathogens. No antagonism was observed. Santalum spp. and Vetiveria zizanioides essential oils contributed the most to antimicrobial activity in combination. Essential oil combinations are presented as a viable option in wound therapy.
