title: Structure of the capsular polysaccharide of Actinobacillus pleuropneumoniae serotype 5b.
abstract: The capsular polysaccharide of Actinobacillus pleuropneumoniae serotype 5b (strain L20) was found to be a high molecular mass polymer composed of 2-acetamido-2-deoxy-D-glucose, D-glucose, and 3-deoxy-D-manno-octulosonic acid (KDO). Methylation analysis, partial hydrolysis and a combination of homonuclear and 1H-detected heteronuclear shift-correlated nuclear magnetic resonance experiments showed the polysaccharide to be a branched polymer of a trisaccharide repeating unit, having the structure: [formula; see text]
