ABSTRACT
The chemical structure of the O-antigen of a proposed new provisional serotype of Shigella flexneri has been determined. Methylation analysis, GLC-MS, 1H-NMR and 13C-NMR showed that the linear O-antigenic polysaccharide is the same as for all S. flexneri [Kenne, L., Lindberg, B., Petersson, K. & Romanowska, E. (1977) Carbohydr. Res. 56, 363-370]. A novel structural feature is that the disaccharide alpha-D-Glcp-(1----2)-alpha-D-Glcp is linked to O4 of the N-acetyl-glucosamine residue. (Formula see text) Western blotting of the lipopolysaccharide with an E. coli R3 core-specific monoclonal antibody, suggested the presence of an E. coli R3 core.
