title: The capsular antigen of Escherichia coli serotype O8:K102:H-.
abstract: The structure of the capsular antigen of E. coli O8:K102:H- was investigated by methylation analysis, beta-elimination of the methylated polysaccharide, lithium-ethylenediamine mediated degradation, and by 1D and 2D 1H and 13C NMR spectroscopy of the lithium-degraded and native polysaccharides. The capsular antigen was shown to have the following branched pentasaccharide repeating unit: [formula: see text]
