Evidence for the existence of two phenotypes of piglets born to experimental herds was obtained based on the susceptibility of intestinal brush borders to adhesion of K99-positive Escherichia coli. The enterocytes of the K99-receptive piglets displayed a characteristic sialoglycolipid pattern, with a higher content of the monosialoglycolipids II3NeuGc-LacCer (GM3Gc), IV3NeuGc-nLcOse4Cer (SPGGc) and IV3NeuAc-nLcOse4Cer (SPG) and the oligosialogangliosides IV3NeuAc,II3NeuAc-GgOse4Cer (GD1a), II3(NeuAc)2-GgOse3Cer (GD2), II3(NeuAc)2-GgOse4Cer (GD1b) and IV3NeuAc,II3(NeuAc)2-GgOse4Cer (GT1b) when compared to the gangliosides of non-receptive piglets. The gangliosides from enterocytes of the non-receptive piglets were mainly the monosialogangliosides II3NeuAc-GgOse3Cer (GM2) and II3NeuAc-LacCer (GM3), only traces of the other sialoglycolipids being detected. Adhesion of 14C-labelled K99-positive E. coli cells to the piglet small intestinal sialoglycolipids, as tested by the thin-layer chromatogram overlay assay, revealed that the receptive enterocyte membrane was richer in glycolipids containing K99 receptor structures than the non-receptive enterocyte. Adhesion of K99-positive E. coli correlated with the degree of sialylation of the brush border glycolipids.
