title: Structure of the capsular polysaccharide from Actinobacillus pleuropneumoniae serotype 7.
abstract: The structure of the capsular polysaccharide antigen of A. pleuropneumoniae serotype 7 was determined using 1D- and 2D-n.m.r. methods. Dephosphorylation, methylation, and g.l.c.-mass spectrometry methods were used to confirm the analysis. The type-7 specific polysaccharide was a high-molecular-weight teichoic acid-type polymer of D-galactose, glycerol, and phosphate (2:1:1), composed of glycosylglycerol repeating units joined through monophosphate diester linkages and with the structure: [formula: see text]
