Lipopolysaccharides from various strains of Vibrio cholerae have been found to consist of distinct O-specific side chain and core polysaccharide regions in their degraded polysaccharides. The major identifiable components in the core polysaccharide were phosphorus, glucose, heptose, fructose, and ethanolamine phosphate, with small amounts or traces of mannose, rhamnose, and D-perosamine. On the...

Lipopolysaccharides were isolated from Cifrobacfer freundii ATCC 8090 by 44% aqueous-phenol fractionation. The lipopolysaccharides were isolated from the phenol phase and phenol-water interphase fractions. Acid hydrolysis yielded glucosamine and a 3-amino sugar identified as 3amino-3,6-dideoxyglucose by comparison with authentic 3-amino-3,6-dideoxyhexoses by ion exchange chromatography. Compari...

Hepatocellular carcinoma is one of the fatal malignancies and is considered as the third leading cause of death. Mutations, genetic modifications, dietary aflatoxins, or impairments in the regulation of oncogenic pathways may bring about liver cancer. An effective barrier against hepatotoxins is offered by gut-liver axis as a change in gut permeability and expanded translocation of lipopolysacc...

To extend the knowledge on the fragments of Proteus penneri lipopolysaccharide core regions, which determine the cross-reactions with specific antibodies, serological studies were performed by use of P. penneri 7 core-specific antiserum and Proteus sp. lipopolysaccharides. Different reactivity of the tested antiserum with three groups of antigens suggested differences in their core regions' epi...

The cell wall lipopolysaccharides from 17 species belonging to the genus Xanthomonas were extracted from the cells with hot 45% phenol. After purification, the components of the polysaccharide were obtained by acid hydrolysis of the lipopolysaccharide and were quantitatively assayed. Data obtained show that all preparations contained uronic acid, phosphate, and mannose in molar ratios of approx...
