Haemagglutinins and Adhesion of Escherichia Coli To Hep2 Epithelial Cells

S-fimbriae mediated adhesion of Escherichia coli to human buccal epithelial cells is age independent.

S-fimbriated Escherichia coli, which cause sepsis and meningitis in the newborn, bind to sialic acid-containing glycoprotein structures on the surface of human buccal epithelial cells. The dependence of this binding on host age was examined. S-fimbriated E. coli adhered in comparable numbers to cells in newborns, infants, children and adults (23.0 +/- 8.6; 23.1 +/- 11.5; 24.7 +/- 7.9; 28.9 +/- ...

Adhesion of Escherichia coli to human uroepithelial cells in vitro.

Optimal conditions for in vitro adherence of Escherichia coli to uroepithelial cells, previously shown to more efficient for strains causing acute symptomatic than that for strains causing "asymptomatic" urinary tract infections, were investigated. Uroepithelial cells from fresh morning urine of healthy individuals and E. coli bacteria from patients with various forms of urinary tract infeciton...

Adherence of diarrheagenic Escherichia coli strains to epithelial cells.

Enteropathogenic Escherichia coli (EPEC) adhesion to intestinal epithelial cells: role of bundle-forming pili (BFP), EspA filaments and intimin.

Enteropathogenic Escherichia coli (EPEC), an important paediatric diarrhoeal pathogen, employs multiple adhesins to colonize the small bowel and produces characteristic 'attaching and effacing' (A/E) lesions on small intestinal enterocytes. EPEC adhesins that have been associated with A/E adhesion and intestinal colonization include bundle-forming pili (BFP), EspA filaments and intimin. BFP are...

Secretory immunoglobulin A and G antibodies prevent adhesion of Escherichia coli to human urinary tract epithelial cells.

The adhesion of Escherichia coli to human urinary tract epithelial cells was inhibited by commercial gamma globulin, the total immunoglobulin fraction of human breast milk and urine, as well as the isolated immunoglobulin G and secretory immunoglobulin A fractions of urine from patients with acute pyelonephritis. Urinary anti-O6 antibodies reduced the adhesion of several O6 strains. Absorption ...
