title: Determination of the structure of the Escherichia coli K100 capsular polysaccharide, cross-reactive with the capsule from type b Haemophilus influenzae.
abstract: The structure of the Escherichia coli K100 capsular polysaccharide, cross-reactive with that from type b Haemophilus influenzae, was determined by using a combination of chemical and spectroscopic techniques. The structure of the K100 repeating unit was found to be----3)-beta-D-Ribf-(1----2)-D-ribitol-5-(PO4----. The K100 polysaccharide is thus identical in composition to, but different in linkage from, the H. influenzae type b capsular polysaccharide, which has beta-D-Ribf-(1----1)-D-ribitol linkages.
