Figure 7From: ProQ binding to small RNA RyfA promotes virulence and biofilm formation in avian pathogenic Escherichia coliRyfA promoted APEC/ExPEC biofilm formation. A CLSM visualization of biofilms formed by WT FY26, FY26ΔryfA, and FY26CryfA, which all exhibited green fluorescence. B Assessment of the biofilm formation capabilities of WT FY26, FY26ΔryfA, and FY26CryfA and the negative control strain MG1655 using a crystal violet assay. APEC strains were grown in LB medium supplemented with 5 g/L glucose.Back to article page
