Binding of pili from uropathogenic Escherichia coli to membranes secreted by human colonocytes and enterocytes

Infect Immun. 1999 Nov;67(11):6161-3. doi: 10.1128/IAI.67.11.6161-6163.1999.


PapG adhesins mediate the binding of uropathogenic Escherichia coli. Although receptors for these adhesins have not been demonstrated in intestinal epithelia, the colonic microflora includes strains of uropathogenic E. coli. We now report that surfactant-like particles secreted by the human intestine contain receptors for PapG adhesins and may provide an intestinal habitat for uropathogenic bacteria.
