Single and combined antibacterial activities of cumin, cardamom, and dill weed essential oils against Campylobacter jejuni, Campylobacter coli, Escherichia coli, Staphylococcus aureus, and mixed cultures were determined by using the broth microdilution method for determining minimum inhibition concentrations. Among the bacteria tested, C. coli and C. jejuni were generally more susceptible to essential oils, with lower minimum inhibition concentrations. The minimum inhibition concentration values were obtained against Gram‐negative and Gram‐positive bacteria tested within the range of 0.012–15.00 and 3.75–15.00 μL/mL, respectively. Fractional inhibitory concentrations (FICs) were also calculated to evaluate the antimicrobial activities of essential oil combinations. Although the combined effects of essential oils changed depending on the strain and the type of essential oils used, generally the use of combinations increased the efficacy of the essential oils. Interestingly, according to the FIC index, the most synergetic effect was against C. coli and C. jejuni. This study has demonstrated the potential use of cardamom, cumin, and dill weed essential oils, and their combinations, against important pathogenic bacteria and their mixed cultures.

评价精油对控制弯曲杆菌,空肠弯曲菌,大肠杆菌,金黄色葡萄球菌和混合培养物的单一和联合抗菌作用

孜然,豆蔻和莳萝杂草精油对空肠弯曲菌弯曲杆菌大肠杆菌金黄色葡萄球菌和混合培养物的单一和联合抗菌活性通过使用肉汤微量稀释法确定最小抑菌浓度来确定。在测试的细菌中,大肠杆菌空肠弯曲菌通常对精油更敏感,最低抑菌浓度较低。获得的针对革兰氏阴性和革兰氏阳性细菌的最小抑菌浓度值分别在0.012–15.00和3.75–15.00μL/ mL的范围内。还计算了分数抑制浓度(FIC),以评估精油组合的抗菌活性。尽管精油的组合作用根据所使用的精油的应变和类型而变化,但是通常组合使用可以提高精油的功效。有趣的是,根据FIC指数,最协同的作用是针对大肠杆菌空肠梭菌。这项研究证明了豆蔻,小茴香和莳萝杂草精油及其组合对重要的病原菌及其混合培养物的潜在用途。
