NMR Study of the O-Specific Polysaccharide and the Core Oligosaccharide from the Lipopolysaccharide Produced by Plesiomonas shigelloides O24:H8 (Strain CNCTC 92/89)

Lundqvist, Lena; Kaszowska, Marta; Sandström, Corine


The structures of the O-specific polysacccharide and core oligosaccharide of the lipopolysaccharide from Plesiomonas shigelloides O24:H8, strain CNCTC 92/89, have been investigated by NMR spectroscopy and ESI mass spectrometry. The O-specific polysaccharide was found to be composed of a tetrasaccharide repeating unit consisting of [3)--FucpNAc-(13)--GalpNAcA-(13)--QuipNAc-(1] and of -RhapNAc (14) linked to the GalpNAcA residue. An identical structure has been reported for the capsular polysaccharide of the clinical isolate of Vibrio vulnificus strain BO62316 [1]. The core oligosaccharide was composed of a decasaccharide which structure is identical with these in P. shigelloides serotype O54 [2] and serotype O37 [3].
