Shigella flexneri serotype 2a
[edit] 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-(1-->2)-α-L-Rhap-(1-->3)-α-L-Rhap-(1-->3)-β-D-GlcpNAc-(1-->
