The following structure of the lipid A-core region of the lipopolysaccharide (LPS) from Proteus mirabilis serotype O28 was determined using NMR, MS, and chemical analysis of the core oligosaccharide, obtained by mild acid hydrolysis of LPS, and of the products of alkaline deacylation of the LPS:

Effects of selected carbohydrates and the contribution of the prophenoloxidase cascade system to the adhesion of strains of Pseudomonas aeruginosa and Proteus mirabilis to hemocytes of nonimmune larval Galleria mellonella.

The adhesion of strains of Pseudomonas aeruginosa and Proteus mirabilis to the plasmatocytes and granular cells of nonimmune larval Galleria mellonella was influenced by and varied with the type of carbohydrate. Laminarin enhanced prophenoloxidase activation and bacterial adhesion to the hemocytes

The structure of the carbohydrate backbone of core-lipid A region ofthe lipopolysaccharides from Proteus mirabilis wild-type strain S1959 (serotype O3) and its Ra mutant R110/1959.

Quantitative proteomics analysis reveals the tolerance of Mirabilis jalapa L. to petroleum contamination.

Numai utilizatorii înregistrați pot traduce articole

Petroleum is not only an important energy resource but is also a major soil pollutant. To gain better insight into the adaptability mechanism of Mirabilis jalapa to petroleum-contaminated soil, the protein profiles of M. jalapa root were investigated using label-free quantitative proteomics

Experimental diabetes treated with trigonelline: effect on β cell and pancreatic oxidative parameters.

Numai utilizatorii înregistrați pot traduce articole

Oxidative stress in diabetes coexists with a reduction in the antioxidant status, which can further increase the deleterious effects of free radicals. Trigonelline is the major component of Mirabilis jalapa L., which has been used to treat diabetes in China. The present study was designed to

Structure of the neutral O-polysaccharide and biological activities of the lipopolysaccharide of Proteus mirabilis O20.

Numai utilizatorii înregistrați pot traduce articole

Mild acid degradation of the lipopolysaccharide (LPS) of Proteus mirabilis O20 resulted in depolymerisation of the O-polysaccharide to give a repeating-unit pentasaccharide. A polysaccharide was obtained by O-deacylation of the LPS followed by nitrous acid deamination. The derived pentasaccharide

Immunochemical studies on the O-specific side chains of the heterogeneous lipopolysaccharide from Proteus mirabilis O27.

Numai utilizatorii înregistrați pot traduce articole

Chemically and serologically identical O-specific fractions were isolated from two different lipopolysaccharide (LPS) preparations of Proteus mirabilis O27. The release of a labile constituent in mild hydrolysis deprived those fractions of their serological activity. The compound was identified as

Serotyping of Proteus mirabilis clinical strains based on lipopolysaccharide O-polysaccharide and core oligosaccharide structures.

The aim of this work was to serotype Proteus mirabilis urinary tract infection (UTI) strains based on chemically defined O-antigens with the use of two clinical collections from Sweden and Poland consisting of 99 and 24 UTI strains, respectively. A simple two-step serotyping scheme was proposed

Full structure of the O-specific polysaccharide of Proteus mirabilis O24 containing 3,4-O-[(S)-1-carboxyethylidene]-D-galactose.

Numai utilizatorii înregistrați pot traduce articole

The structure of a neutral polysaccharide isolated by degradation with dilute acetic acid of the lipopolysaccharide (LPS) of P. mirabilis O24 has been determined recently [E. Literacka et al., FEBS Lett., 456 (1999) 227-231]. Further studies of this LPS using alkaline degradation and hydrolysis at

Structure of the O-polysaccharide of Proteus mirabilis O38 containing 2-acetamidoethyl phosphate and N-linked D-aspartic acid.

Numai utilizatorii înregistrați pot traduce articole

The O-antigen of Proteus mirabilis O38 was found to be unique among bacterial polysaccharides and to have the following structure: [carbohydrate structure in text] where D-Qui4N(Ac-D-Asp) is 4-(N-acetyl-D-aspart-4-ylamino)-4,6-dideoxy-D-glucose and AcEtnP is 2-acetamidoethyl phosphate. Neither of

Influence of quorum sensing signal molecules on biofilm formation in Proteus mirabilis O18.

Numai utilizatorii înregistrați pot traduce articole

The influence of basis of quorum sensing molecules on Proteus strains is much less known as compared to Pseudomonas or Escherichia. We have previously shown that a series of acylated homoserine lactones (acyl-HSL) does not influence the ureolytic, proteolytic, or hemolytic abilities, and that the

Structure and serological characterization of the O-antigen of Proteus mirabilis O18 with a phosphocholine-containing oligosaccharide phosphate repeating unit.

Numai utilizatorii înregistrați pot traduce articole

A phosphorylated, choline-containing polysaccharide was obtained by O-deacylation of the lipopolysaccharide (LPS) of Proteus mirabilis O18 by treatment with aqueous 12% ammonia, whereas hydrolysis with dilute acetic acid resulted in depolymerisation of the polysaccharide chain by the glycosyl

Functional identification of the Proteus mirabilis core lipopolysaccharide biosynthesis genes.

Numai utilizatorii înregistrați pot traduce articole

In this study, we report the identification of genes required for the biosynthesis of the core lipopolysaccharides (LPSs) of two strains of Proteus mirabilis. Since P. mirabilis and Klebsiella pneumoniae share a core LPS carbohydrate backbone extending up to the second outer-core residue, the

Novel Insights into the Proteus mirabilis Crystalline Biofilm Using Real-Time Imaging.

The long-term use of indwelling catheters results in a high risk from urinary tract infections (UTI) and blockage. Blockages often occur from crystalline deposits, formed as the pH rises due to the action of urease-producing bacteria; the most commonly found species being Proteus mirabilis. These
