Abstract:
(P < 0.05 ).Scanning electron microscopy showed that the three-dimensional structure of mix-biofilm in control group was more complex.As real-time PCR showed,after 6-hour culture,the expressions of icaA,fbe,aap,hwp1, als3 and efg1 genes in Farnesol group were down-regulated compared to those in control group and after 24-hour culture the expressions of aap,hwp1,als3 and efg1 genes in Farnesol group were down-regulated compared to those in control group.Conclusion With the intervention by fungal quorum sensing molecules Farnesol,the structure in control group became denser and more complex than that in Farnesol group.This change may have a closer correlation with the down-regulated expressions of als3,hwp1 and efg1 genes,which are related to the formation of Candida albicans biofilms.
