The lipopolysaccharide-protein somatic

, usually from
gram-negative bacteria
, important in the serological

of enteric bacilli. The O-specific chains determine the specificity of the
O antigens
of a given serotype.

are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell. (From Singleton & Sainsbury,
