Structural characterization of the O-antigenic polysaccharide from the lipopolysaccharide of Vibrio cholerae O37
The chemical structure of the O-antigenic polysaccharide isolated from the lipopolysaccharide of Vibrio cholerae O37 by mild acid hydrolysis was elucidated. The O-antigenic polysaccharide is found to consist of D-glucose, N-acetyl-D-Quinovosamine and small amount of 4-O-methyl-N-acetyl-D-quinovasamine. The structure of the O-antigen is established by using sugar and methylation analyses, Smith ...
متن کاملStructural Characterization of the Extracellular Polysaccharide from Vibrio cholerae O1 El-Tor
The ability to form biofilms is important for environmental survival, transmission, and infectivity of Vibrio cholerae, the causative agent of cholera in humans. To form biofilms, V. cholerae produces an extracellular matrix composed of proteins, nucleic acids and a glycoconjugate, termed Vibrio exopolysaccharide (VPS). Here, we present the data on isolation and characterization of the polysacc...
متن کاملStructural determination of the O-antigenic polysaccharide from Escherichia coli O141.
The structure of the O-antigenic polysaccharide from Escherichia coli O141 has been determined. NMR spectroscopy and sugar and methylation analyses were the principal methods used. The sequence of the sugar residues could be determined by NOESY and heteronuclear multiple-bond connectivity (HMBC-) NMR experiments. The polysaccharide is composed of pentasaccharide repeating units with 1 O-acetyl ...
متن کاملConformation of the hexasaccharide repeating subunit from the Vibrio cholerae O139 capsular polysaccharide.
In the past decade, several outbreaks of cholera have been reported to be caused by Vibrio cholerae O139, a strain which differs from the more common O1 strain in that the former is encapsulated. The hexasaccharide repeating subunit has been isolated from the V. cholerae O139 capsular polysaccharide by digestion with a recently discovered polysaccharide lyase derived from a bacteriophage specif...
متن کاملEvaluation in Mice of a Conjugate Vaccine for Cholera Made from Vibrio cholerae O1 (Ogawa) O-Specific Polysaccharide
BACKGROUND Protective immunity against cholera is serogroup specific. Serogroup specificity in Vibrio cholerae is determined by the O-specific polysaccharide (OSP) of lipopolysaccharide (LPS). Generally, polysaccharides are poorly immunogenic, especially in young children. METHODOLOGY Here we report the evaluation in mice of a conjugate vaccine for cholera (OSP:TThc) made from V. cholerae O1 ...
