The elucidation of the structure of the core part of the LPS from Plesiomonas shigelloides serotype O17 expressing O-polysaccharide chain identical to the Shigella sonnei O-chain

Plesiomonas shigelloides O17 LPS contains the same O-antigenic polysaccharide chain as a causative agent of dysentery, Shigella sonnei. This polysaccharide can be used as a component of a vaccine against dysentery. Core part of the P. shigelloides O17 LPS was studied using NMR and mass spectrometry and the following structure was proposed: Significant similarity of the P. shigelloides O17 LPS core with the structure of the P. shigelloides O54 core was observed.
