Abstract

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)-α-FucpNAc-(1→3)-α-GalpNAcA-(1→3)-α-QuipNAc-(1→] and of α-RhapNAc (1→4) 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]. View Full-Text
