✦ Synopsis
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.
