Differential binding of Escherichia coli O157:H7 to alfalfa, human epithelial cells, and plastic is mediated by a variety of surface structures

Article Abstract:

The role of different mediators of adherence in the ability of Escherichia coli O157:H7 to bind alfalfa sprouts and seed coats is investigated and is attempted to correlate differences in adherence to plant surfaces with those observed on Caco-2 intestinal cells and during the formation of biofilms on plastic in vitro. The results have shown that binding to the three types of surfaces were mediated by overlapping but distinct sets of genes and the only gene that appeared to be irreplaceable for binding the plant surfaces was ompA.

Tight modulation of Escherichia coli bacterial biofilm formation through controlled expression of adhesion factors

Article Abstract:

The development of two new genetic tools enabling the constitutive and inducible expression of any gene at its native locus is described. This study provides the improved knowledge of bacterial biofilm formation at the molecular level which can be used to control cell surface adhesion in bacterial strains of interest.

Oriented adhesion of Escherichia coli to polystyrene particles

Article Abstract:

The adhesion of nonflagellated Escherichia coli strain K-12 to polystyrene (PS) latex spheres or glass capillaries is observed by using several techniques. Data indicate that nanodomain on the bacterial ends are important for adhesion and that the time scale for irreversible adhesion is short.
