Division of Biological Sciences, National Research Council of Canada, Ottawa, Ontario.

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]

D016667	Bacterial Capsules	An envelope of loose gel surrounding a bacterial cell which is associated with the virulence of pathogenic bacteria. Some capsules have a well-defined border, whereas others form a slime layer that trails off into the medium. Most capsules consist of relatively simple polysaccharides but there are some bacteria whose capsules are made of polypeptides.	Bacterial Capsule,Capsule, Bacterial,Capsules, Bacterial
