Structure of the O-polysaccharide of Proteus mirabilis O19 and reclassification of certain Proteus strains that were formerly classified in serogroup O19.
INTRODUCTION Bacteria of the genus Proteus are a common cause of urinary tract infections. The O-polysaccharide chain of their LPS (O-antigen) defines the serological specificity of these bacteria. Based on the immunospecificity of the O-antigens, two species, P. mirabilis and P. vulgaris, were classified into 49 O-serogroups, and more O-serogroups for strains of these species and P. penneri ha...
متن کاملImmunochemical studies on the O-antigens of Proteus mirabilis O23 and Proteus vulgaris O23.
Analysis by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy demonstrated that the O-specific polysaccharides of Proteus mirabilis PrK 42/57 and P. vulgaris PrK 43/57 are structurally similar to that of P. vulgaris PrK 44/57 and different from the polysaccharide of P. mirabilis PrK 41/57 studied earlier. The lipopolysaccharides of these strains were tested using enzyme immunosorbent ass...
متن کاملStructural studies of the O-specific polysaccharide from Plesiomonas shigelloides strain CNCTC 113/92.
The structure of the O-specific side chain of the lipopolysaccharide (LPS) of Plesiomonas shigelloides, strain CNCTC 113/92 has been investigated by NMR spectroscopy, matrix-assisted laser desorption/ionization time of flight mass spectrometry and sugar and methylation analysis. It was concluded that the polysaccharide is composed of a hexasaccharide repeating unit with the following structure:...
متن کاملThe structure of the capsular polysaccharide from a swarming strain of pathogenic Proteus vulgaris.
The structure was determined for the capsular polysaccharide (CPS) isolated from a swarming strain of Proteus vulgaris, CP2-96, which was obtained from the spleen of an infected mouse. The CPS was extracted from the cell pellet by hot water, precipitated with ethanol, and further purified by gel-permeation chromatography. The structure was established by glycosyl composition and linkage analyse...
