Chemotypes of Fusobacterium nucleatum lipopolysaccharides. 1978

G Fredriksen, and T Hofstad

Lipopolysaccharides (LPS) were isolated from 20 strains of Fusobacterium nucleatum and examined by paper chromatography, gas liquid chromatography and colorimetric methods for the presence of neutral sugars, amino sugars and 2-keto-3-dexoxy-octonate (KDO). The LPS had in common glucosamine, L-glycero-D-manno-heptose, glucose and KDO. The KDO content was low. Galatose, rhamnose and D-glycero-D-manno-heptose were found in some strains. Based on the sugar composition of the LPS, the F. nucleatum strains could be classified into six chemotypes.

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
D011135	Polysaccharides, Bacterial	Polysaccharides found in bacteria and in capsules thereof.	Bacterial Polysaccharides
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D002853	Chromatography, Liquid	Chromatographic techniques in which the mobile phase is a liquid.	Liquid Chromatography
D002854	Chromatography, Paper	An analytical technique for resolution of a chemical mixture into its component compounds. Compounds are separated on an adsorbent paper (stationary phase) by their varied degree of solubility/mobility in the eluting solvent (mobile phase).

D003124	Colorimetry	Any technique by which an unknown color is evaluated in terms of standard colors. The technique may be visual, photoelectric, or indirect by means of spectrophotometry. It is used in chemistry and physics. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
D005673	Fusobacterium	A genus of gram-negative, anaerobic, rod-shaped bacteria found in cavities of humans and other animals. No endospores are formed. Some species are pathogenic and occur in various purulent or gangrenous infections.	Sphaerophorus
