| Microbe | Shigella flexneri serotype 2b (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | Chemically, the O-antigen is a polysaccharide chain of variable length, built up by repetitive sequences of tetra- to hexasaccharides. It consists of a basic tetrasaccharide repeating unit consisting of three rhamnoses and one N-acetylglucosamine was common to all S. flexneri strains (except serotype 17): -2)-α-L-Rhap-[branched to α-D-Glcp(1-->4)](1-->2)-α-L-Rhap-(1-->3)-α-L-Rhap-[branched to α-D-Glcp(1-->3)](1-->3)-β-D-GlcpNAc-(1--> |
| BCSDB Structure | 108645 |
| Proposed functions | LPS plays an important virulence role based on its antiphagocytic and endotoxic properties |
