Curcumin as a Promising Antibacterial Agent: Effects on Metabolism and Biofilm Formation in S. mutans
Results of qRT-PCR to examine the gene expression of different virulence systems in S. mutans UA159. (a) EPS synthesis system; (b) carbohydrate metabolism system; (c) quorum-sensing system; (d) two-component transduction system. All targets were amplified using primers. Different gene expression levels were normalized to the level of 16sRNA gene transcripts. Data are presented as the mean ± SD. The asterisks () indicate significant differences (, , ).
