The annexed structure of the capsular polysaccharide of Escherichia coli O9:K35:H- (A104a) has been determined by glycose and methylation analysis, base-catalysed degradation, and 1D and 2D NMR spectroscopy on the polysaccharide and the products obtained by bacteriophage-mediated depolymerisation.

The K16-antigen from E. coli Rk 21510 (O7:K16:H-) is shown to consist of the repeating unit ----2)-beta-D-Ribf-(1----3)-beta-D-Ribf-(1----5)-alpha-Kd op-(2---- of which approximately 33% is O-acetylated at position 3 of the 2-linked ribose.
Trideuteriomethylated and methylated derivatives of the capsular polysaccharide of Escherichia coli K57 were partially cleaved by Et3SiH, using Me3SiOSO2Me and Me3SiOSOeCF 3 as catalysts, to produce oligosaccharide-anhydroalditols. The structures of the trideuteriomethylated trisaccharide-and tetras
