The capsular polysaccharide of A. pleuropneumoniae serotype 10 was found to be composed of a linear disaccharide repeating unit. By use of methylation analysis, partial hydrolysis, g.l.c.--and f.a.b.- m.s., and 1D and 2D n.m.r. studies, the polysaccharide was determined to be a polymer of a repeatin

โฆ Synopsis
The capsular polymer of Actinobacillus pleuropneumoniae serotype 6 (ATCC 33590) was investigated by methylation, dephosphorylation, partial hydrolysis, and 1H- and 13C-n.m.r. methods. It was found to be a high-molecular-weight polymer composed of triglycosylglycerol phosphate repeating-units joined through monophosphate diester linkages, and has the structure: (formula; see text).
