Binding of F41 and K99 fimbriae of enterotoxigenic Escherichia coli to glycoproteins from bovine and porcine colostrum.

F41 and K99 fimbriae of enterotoxigenic Escherichia coli were found to bind to periodate-sensitive oligosaccharides of glycoproteins from bovine and porcine colostrum. Only a minor component of casein fractions (kappa-casein) possessed receptors for one type of fimbriae (K99). Both whey and fat globule membranes were rich in glycoproteins with receptor structures. Porcine colostrum seemed to contain a higher quantity of receptors than bovine colostrum.
