摘要
Abstract
Objective:To study the growth characteristics of Gardnerella vaginalis and Atopobium vaginalis co-cultured,and to explore the effect of Enterococcus faecalis supernatant on biofilm formation in mixed culture of Gardnerella vaginalis and Atopobium vaginalis.Meth-ods:Gardnerella vaginalis and Atopobium vaginalis isolated and identified from vaginal secre-tion samples of BV patients,and the growth and film formation of Gardnerella vaginalis and Atopobium vaginalis co-cultured for 24h,48h and 72h were observed.The growth and acid-pro-ducing ability of Enterococcus faecalis standard strain within 24 hours were observed.The bio-film formation of Gardnerella vaginalis after single culture,mixed culture of Gardnerella vagina-lis and Atopobium vaginalis and co-culture with supernatant of Enterococcus faecalis for 24 hours,48 hours and 72 hours were observed.Results:The film-forming ability of Gardnerella sp.and Atobo sp.co-cultured in the ratio of 2:1 was stronger than that of Gardnerella sp.with the same amount of bacteria,and the difference was statistically significant(P<0.05).Atopobi-um bacteria hardly produce biofilm.The supernatant of Enterococcus faecalis significantly inhib-ited the biofilm formation of Gardnerella simplex and mixed culture of Gardnerella and Atopobi-um(2:1),and the difference was statistically significant(P<0.05).Conclusions:The co-culture of Gardnerella vaginalis and Atopobium vaginalis can promote the formation of biofilm.The supernatant of Enterococcus faecalis can inhibit the biofilm formation of Gardnerella vagina-lis and Gardnerella vaginalis and Atopobium vaginalis.关键词
