The structure of the capsular antigen from Escherichia coli O8:K46:H30 was elucidated by methylation analysis and 1D and 2D 1H- and 13C-NMR spectroscopy, and by methylation analysis, 1D- and 2D-NMR spectroscopy, and FABMS of the oligosaccharide-alditol obtained after dephosphorylation of the polymer with aqueous hydrofluoric acid. The capsular polymer is of the teichoic acid type and has the following repeating unit. [Formula: see text].
