Virulence-related traits, RDAR and cell adherence. (A) Development of RDAR morphotype is impaired in Suc++ mutants. Cells were replica-plated on CR (Congo Red) plates and incubated at 25°C for 48 h. (B) Cell adherence to epithelial cells. The adherence was expressed as the percentage of cells surviving the washing process. rpoS designates the constructed rpoS null-deletion mutant.
