Influence of plasmid pO157 on Escherichia coli O157:H7 Sakai biofilm formation.
The role of plasmid pO157 in biofilm formation was investigated using wild-type and pO157-cured Escherichia coli O157:H7 Sakai. Compared to the wild type, the biofilm formed by the pO157-cured mutant produced fewer extracellular carbohydrates, had lower viscosity, and did not give rise to colony morphology variants that hyperadhered to solid surfaces.
