Structural and serological characterization of the O-chain polysaccharide of Aeromonas salmonicida strains A449, 80204 and 80204-1
Carbohydrate Research 340(4) (2005) 693-700
 

The O-chain polysaccharide (O-PS) of Aeromonas salmonicida was studied by a combination of compositional, methylation, CE-ESMS and one- and two-dimensional NMR analyses. It was found to be a branched polymer of trisaccharide-repeating units composed of l-rhamnose (Rha), d-glucose (Glc), 2-acetamido-2-deoxy-d-mannose (ManNAc) and O-acetyl group (OAc) and having the following structure: CE-ESMS analysis of A. salmonicida cells from strains A449, 80204 and 80204-1 grown under different conditions confirmed that the O-PS structure was conserved. ELISA-based serological study with native LPS-specific antisera performed on the native O-PS and its O-deacetylated and periodate-oxidized derivatives confirmed the importance of the O-PS backbone structure as an immunodominant determinant
