title: Receptor binding specificity and pathogenicity of Escherichia coli F165-positive strains isolated from piglets and calves and possessing pap related sequences.
abstract: Most of 82 F165-positive Escherichia coli isolated from calves and piglets with diarrhea or septicemia and possessing pap related sequences caused mannose-resistant, neuraminidase-resistant hemagglutination of human and bovine erythrocytes. Less than half of these isolates demonstrated binding specificity for the alpha-D-galactosyl-(1-4)-beta-D-galactopyranose or galactose-N-acetyl-alpha-(1-3) galactose-N-acetyl moieties recognized by P and F (or Prs) adhesins respectively. Binding specificity for the galactose-N-acetyl-alpha-(1-3) galactose-N-acetyl moiety was associated with isolates causing septicemia in newborn piglets.
