Binomial	Shigeila sonnei

Surface Characteristics

Lipopolysaccharide (LPS) molecules consist of three structural regions: a lipid A region, which anchors the molecule in the bacterial outer membrane; an intermediate core region; and a distal, serotype-specific O-polysaccharide chain (O chain or O-antigen). Whereas the chemical composition and structure of 0 chains are highly variable, the core moiety is more conserved. Seven types of LPS core structures, namely, Ra, Ri to R4, K-12, and B, have been found in members of the family Enterobacteriaceae

Pathogenic Activity

Together with Shigella flexneri, it is responsible for 90% of shigellosis. It also polymerizes host cell actin.
