Chemical composition, ultrastructure and some serological properties of lipopolysaccharides from Leptotrichia buccalis. 1982

N K Birkeland, and T Hofstad

Lipopolysaccharide (LPS) was extracted with aqueous phenol from Leptotrichia buccalis strains L 11, ATCC 14201 and ATCC 19616. Virtually all the LPS was found in the water phase. LPS could also be extracted with phenol/chloroform/petroleum ether, but not with cold trichloroacetic acid. All LPS preparations contained D-glycero-D-manno-heptose, galactose, glucose, glucosamin, n-dodecanoate, 3-hydroxy-n-tetradecanoate and phosphorus. In addition LPS from L11 contained 2-keto-3-deoxyoctonate and an unidentified aldose. LPS from L11 was serologically distinct from LPS of ATCC 14201 and ATCC 19616. LPS from the two latter strains crossreacted.

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
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
D002241 Carbohydrates A class of organic compounds composed of carbon, hydrogen, and oxygen in a ratio of Cn(H2O)n. The largest class of organic compounds, including STARCH; GLYCOGEN; CELLULOSE; POLYSACCHARIDES; and simple MONOSACCHARIDES. Carbohydrate
D003429 Cross Reactions Serological reactions in which an antiserum against one antigen reacts with a non-identical but closely related antigen. Cross Reaction,Reaction, Cross,Reactions, Cross
D000606 Amino Sugars SUGARS containing an amino group. GLYCOSYLATION of other compounds with these amino sugars results in AMINOGLYCOSIDES. Amino Sugar,Sugar, Amino,Sugars, Amino
D001438 Bacteroidaceae A family of gram-negative bacteria found primarily in the intestinal tracts and mucous membranes of warm-blooded animals. Its organisms are sometimes pathogenic.
D013400 Sugar Acids MONOSACCHARIDES and other sugars that contain one or more carboxylic acid moieties. Acids, Sugar
