An O-specific polysaccharide from lipopolysaccharide of Yersinia intermedia pathogenic strain 680 has been isolated and shown to be a serologically active fructane. Serological specificity of the lipopolysaccharide and the fructane was studied by reactions of precipitation and of inhibition of passive hemolysis. On the basis of methylation studies, 13C NMR spectroscopy, and immunochemical data the following structure was proposed for the repeating unit of the O-specific polysaccharide: (Formula: see text)

UI MeSH Term Description Entries
D008070 Lipopolysaccharides Lipid-containing polysaccharides which are endotoxins and important group-specific antigens. They are often derived from the cell wall of gram-negative bacteria and induce immunoglobulin secretion. The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed) Lipopolysaccharide,Lipoglycans
D009005 Monosaccharides Single chain carbohydrates that are the most basic units of CARBOHYDRATES. They are typically colorless crystalline substances with a sweet taste and have the same general formula CnH2nOn. Monosaccharide,Simple Sugar,Simple Sugars,Sugar, Simple,Sugars, Simple
D009682 Magnetic Resonance Spectroscopy Spectroscopic method of measuring the magnetic moment of elementary particles such as atomic nuclei, protons or electrons. It is employed in clinical applications such as NMR Tomography (MAGNETIC RESONANCE IMAGING).

D015007 Yersinia A genus of gram-negative, facultatively anaerobic rod- to coccobacillus-shaped bacteria that occurs in a broad spectrum of habitats.
D019081 O Antigens The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell.
