Zentralblatt für Bakteriologie. 1. Abt. Originale A, Medizinische Mikrobiologie, Infektionskrankheiten und Parasitologie, 1980
Abstract The immune sera for Candida albicans, C. guilliermondii and C. tropicalis agglutinated Salmonella cholerae-suis (O:6 2 ,7). The immune serum for S. cholerae-suis agglutinated C. albicans, C. guilliermondii and C. tropicalis . Absorption and agglutination cross tests demonstrated common antigenic factor between above mentioned ...

Structure of the O-antigen of Yersinia pseudotuberculosis O:4b

Carbohydrate Research, 2009
The 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-->.

The lipopolysaccharides (O-antigens) of Rhodopseudomonas viridis

Archives of Microbiology, 1974
The present paper deals with the isolation, and chemical and serological characterization of the O-antigens (lipopolysaccharides, LPS) of the photosynthetic gram-negative bacterium Rhodopseudomonas viridis. The LPS are extractable with hot phenol/water, but unlike the phenol-soluble LPS of the closely related species Rhodopseudomonas palustris, the R ...

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.

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.

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

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.

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 ...
