目的研究阴道卷曲乳酸杆菌对阴道致病菌的体外生物拮抗作用。方法将阴道卷曲乳酸杆菌分别与3株阴道致病菌(金黄色葡萄球菌、大肠埃希菌、粪肠球菌)混合接种于GAM液体培养基中进行厌氧培养,通过平板菌落计数法计算阴道致病菌的菌数。结果经混合培养后阴道致病菌的菌数明显下降。结论阴道卷曲乳酸杆菌A7在体外能明显抑制3株肠道致病菌的生长繁殖。
Objective To study the biological antagonism of vaginal curly lactic acid bacteria to vaginal pathogens in vitro. Methods Vaginal curly lactic acid bacteria were mixed with three strains of vaginal bacteria (Staphylococcus aureus, Escherichia coli and Enterococcus faecalis) respectively in GAM liquid medium for anaerobic culture. The colony count Bacteria bacteria. Results After mixed culture vaginal bacteria significantly decreased the number of bacteria. Conclusion Vaginal curly Lactobacillus A7 can significantly inhibit the growth and reproduction of three enteric pathogens in vitro.
