O-Polysaccharides (O-antigens) were isolated from Escherichia coli O13, O129, and O135 and studied by chemical analyses along with 2D (1)H and (13)C NMR spectroscopy. They were found to possess a common -->2)-l-Rha-(alpha1-->2)-l-Rha-(alpha1-->3)-l-Rha-(alpha1-->3)-d-GlcNAc-(beta1--> backbone, which is a characteristic structural motif of the O ...

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.

The lipopolysaccharide (LPS) is the major constituent of the outer leaflet of the outer membrane of Gram-negative bacteria. Its lipid A moiety is embedded in the membrane and serves as an anchor for the rest of the LPS molecule. The outermost repetitive glycan region of the LPS is linked to the lipid A through a core oligosaccharide (OS), and is ...

Detection of O antigens inEscherichia coli
Animal Health Research Reviews, 2011AbstractLipopolysaccharide on the surface ofEscherichia coliconstitutes the O antigens which are important virulence factors that are targets of both the innate and adaptive immune systems and play a major role in host–pathogen interactions. O antigens are responsible for antigenic specificity of the strain and determine the O serogroup.

Structural Studies on the O-Antigen of Aeromonas salmonicida
European Journal of Biochemistry, 1983Lipopolysaccharide from a strain of Aeromonas salmonicida salmonicida was isolated from cells by the aqueous phenol method in 2.3% yield (based on dry weight of bacteria). Hydrolysis of the lipopolysaccharide in 1% acetic acid afforded O-polysaccharide (19% by weight), core-oligosaccharide (12.2%) and lipid A (44.6%).

O antigen-dependent mutant of bacteriophage T5
Journal of Virology, 1984A T5 mutant is described which showed normal infection of Escherichia coli F but virtually no infection of cells lacking the E. coli F O antigen. This was due to very poor adsorption to the O antigen-deficient cells. Inactivation kinetics with anti-T5 serum and adsorption and desorption kinetics to receptor-deficient E.

O‐Antigenic Cross‐Reactivity In Fusobacterium Nucleatum
Acta Pathologica Microbiologica Scandinavica Section B Microbiology, 1979Lipopolysaccharides (LPS) of the same chemotype isolated from seven strains of Fusobacterium nucleatum were examined by indirect haemagglutination and inhibition of haemagglutination in unabsorbed and absorbed antisera. Four common major antigenic specificities were detected, and two of the LPS examined contained antigenic specificities not shared with

Role of O-antigen variation in the immune response
Trends in Microbiology, 1995The O antigen is an extremely variable surface polysaccharide of Gram-negative bacteria. This variation is thought to allow the various clones of a species each to present a surface that offers a selective advantage in the niche occupied by that clone.
