Relative expression of QS gene (luxS) and QS-regulated virulence genes (csgA, fimA, and fliC) associated with the production of virulence factors in UPEC, following treatment with sub-MICs of (a) Carvacrol, (b) Cinnamaldehyde, and (c) Eugenol. Gene expression was normalized with gapA and represented relative to the expression of genes in the untreated control. The error bars indicate SDs. The p-values indicate the significance of fold decrease at *p < 0.05 and fold increase at +++p < 0.001 and ++++p < 0.0001
