Structure of the O-antigen of Yersinia pseudotuberculosis O:4b
Carbohydrate Research, 2009The structure of the long-chain O-antigen of Yersinia pseudotuberculosis O:4b containing two uncommon deoxy sugars, tyvelose (3,6-dideoxy-d-arabino-hexose, Tyv) and 6-deoxy-d-manno-heptose (D-6dmanHep), was established by 1D and 2D NMR spectroscopy as alpha-Tyvp-(1-->3)-beta-D-6dmanHepp 1-->4 -->3)-alpha-D-Galp-(1-->3)-beta-D-GlcpNac-(1-->.

Structural studies of the Vibrio cholerae o-antigen
Carbohydrate Research, 1979The dominant part of the O-antigen of Vibrio cholerae is a homopolysaccharide composed of (1 leads to 2)-linked 4-amino-4,6-dideoxy-alpha-D-mannopyranosyl (perosaminyl) residues, in amino groups of which are acylated by 3-deoxy-L-glycero-tetronic acid. Most of the amino sugar is decomposed during acid hydrolysis. Treatment of the polymer with anhydrous

The O-antigen is an important component of the outer membrane of Gram-negative bacteria. It is a repeat unit polysaccharide and consists of a number of repeats of an oligosaccharide, the O-unit, which generally has between two and six sugar residues.

Enteroinvasive Escherichia coli strains have been found in the following O serogroups: O28ac, O112ac, O124, O136, O143, O144, O152, and O164. The biochemical reactions of these enteroinvasive E. coli strains are often similar to those of Shigella strains, and identification may be difficult.

Structural studies of the O-antigen from Vibrio cholerae O:21
Carbohydrate Research, 1986The O-antigen from Vibrio cholerae O:21 has been investigated, using n.m.r. spectroscopy, methylation analysis, and Smith degradation as the main methods. It is concluded that the O-antigen is composed of tetrasaccharide repeating-units having the following structure (in which Hep = D-glycero-D-manno-heptose). (Formula: see text).

Structural studies of the Vibrio cholerae O:5 O-antigen polysaccharide
Carbohydrate Research, 1993The O-polysaccharide from Vibrio cholerae O:5 has been investigated, using NMR spectroscopy as the main method. Fast atom bombardment mass spectrometry (FABMS) studies of fragments obtained on treatment with anhydrous hydrogen fluoride or methanolic hydrogen chloride gave further structural information.

Structure of the O-antigen of Yersinia pseudotuberculosis O:4a revised
Carbohydrate Research, 2009The O-specific polysaccharide was isolated by mild acid degradation of the lipopolysaccharide of Yersinia pseudotuberculosis O:4a and studied by NMR spectroscopy, including 2D ROESY and (1)H, (13)C HMBC experiments. The following structure of the pentasaccharide repeating unit of the polysaccharide was established, which differs from the structure ...

Abstract In this short communication, a report is presented on the antigenic relationship(s) between type strains in genus Hanseniaspora, Kloeckera and the O antigens of E. coli (O:75, O:163), S. cholerae-suis (O : 62, 7) and S. aberdeen (O:11).
