Abstract:
The capsular polysaccharide of Haemophilus (Actinobacillus) pleuropneumoniae serotype 5 (ATCC 33377) was found to be a linear type polysaccharide of a repeating disaccharide unit composed of 2-acetamido-2-deoxy-D-glucose and 3-deoxy-D-manno-2-octulosonic acid (dOclA). By composition analysis, methylation, partial hydrolysis and 1H and 13C nuclear magnetic resonance studies, it was concluded that the capsular polysaccharide is a high-molecular-mass unbranched polymer having the structure: [6)-alpha-D-GlcNAcp-(1-5)-beta-dOclAp-(2]n.
