โฆ Synopsis
The structure of the O-antigen polysaccharide of A. pleuropneumoniae serotype 7 was investigated by methylation analysis, partial acid hydrolysis, periodate oxidation, and 1H- and 13C-n.m.r. spectroscopy. The polysaccharide repeating-unit consists of a branched tetrasaccharide having the following structure. [formula: see text]

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
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
The 0 antigen obtained from the lipopolysaccharide of Yersinia mckeri serotype 01, by mild acid hydrolysis, is composed of a branched tetrasaccharide repeating unit containing 2-acetamidino-2,6-dideoxy-L-galactose (L-FucAm), 2-acetamido-2-deoxy-D-glucose (D-GlcNAc), and 7-acetamido-3,5,7,9-tetradeox
