Bacterial adherence and invasion assays. The DF-1 cells were infected with APEC strains for 2 h and the adherent bacteria were counted. The invasion bacteria were determined by treatment with gentamicin to kill extracellular bacteria. The commensal E. coli K12 MG1655 was used as a negative control. A The mutant strain ΔdctR showed significantly decreased adhesion capacity compared with the wild-type and complemented strains. B No significant difference was observed for the invasion capacities among these APEC strains. Statistical significance was assessed using one-way ANOVA (**P < 0.01).
