Identification of Salmonella O antigens by coagglutination

Journal of Clinical Microbiology, 1984
This study concerns the preparation of reagents for identifying the somatic O antigens of Salmonella enteritidis. Coagglutination reagents (COAGs) with antibody fixed to killed and stabilized protein A-bearing staphylococci were prepared with antisera which were used for identifying the somatic O antigens of S.

Biosynthesis of lipopolysaccharide O antigens

Trends in Microbiology, 1995
Lipopolysaccharide O antigens are important virulence determinants for many bacteria. O-antigen synthesis is an interesting problem in cell-surface assembly. There are two known assembly pathways, which differ in the cellular location of their polymerization steps and in the direction of chain polymerization.

The O-antigen of Salmonella enterica O13 and its relation to the O-antigen of Escherichia coli O127

Carbohydrate Research, 2010
The following structure of the O-polysaccharide (O-antigen) of Salmonella enterica O13 was established by chemical analyses along with 2D (1)H and (13)C NMR spectroscopy: -->2)-alpha-l-Fucp-(1-->2)-beta-d-Galp-(1-->3)-alpha-d-GalpNAc-(1-->3)-alpha-d-GlcpNAc-(1--> The O-antigen of S.

Structural studies of the Vibrio cholerae o-antigen

Carbohydrate Research, 1979
The 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

In Vitro O-Antigen Ligase Assay

2013
WaaL is a membrane enzyme that catalyzes the glycosidic bonding of a sugar at the proximal end of the undecaprenyl-diphosphate (Und-PP)-O-antigen with a terminal sugar of the lipid A-core oligosaccharide (OS). This is a critical step in lipopolysaccharide synthesis.

New O and H antigens ofPlesiomonas shigelloides and their O antigenic relationships toShigella boydii

Current Microbiology, 1994
Twenty six new O (O51-O76) and 24 new H (H18-H41) antigens forPlesiomonas shigelloides serotyping scheme were defined. The O antigens 54 and 57 were closely related to those ofShigella boydii 2 and 9, respectively, in an a, b-a, c type of relationship.

Immunochemistry of Salmonella O-Antigens

International Archives of Allergy and Applied Immunology, 2009
The binding specificities of antibodies directed against the Salmonella sero-group A-specific O-antigen 2 determinant were characterized by precipitation-inhibition and enzyme-linked immunosorbent assay inhibition tests. Two different antigen O-2-specific antisera were investigated: one conventional factor O-2-serum (elicited by whole heat-killed ...

Structure of O-Antigens

2011
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 ...

Structure of the O-antigen of Yersinia pseudotuberculosis O:4a revised

Carbohydrate Research, 2009
The 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 ...

New O and H antigens of the international antigenic scheme forPlesiomonas shigelloides

Folia Microbiologica, 2000
A revised update of the International antigenic scheme for Plesiomonas shigelloides is presented. Twenty-six new O (O77-O102) and 10 new H (H42-H50 and H1a1d) antigens have been described since 1994. The sources of antigens are mostly human clinical strains, isolates from warmblooded animals and a few environmental cultures.
