Chemical O Antigens

Name O Antigens
Equivalent Terms Antigen, Bacterial O | Antigen, O | Antigens, O | Bacterial O Antigen | O Antigen | O Antigen, Bacterial | O-Antigens | O Specific Polysaccharide | O-Specific Polysaccharide | O Specific Polysaccharides | O-Specific Polysaccharides | Polysaccharide, O-Specific | Polysaccharides, O-Specific
Definition The lipopolysaccharide-protein somatic antigens, usually from gram-negative bacteria, important in the serological classification of enteric bacilli. The O-specific chains determine the specificity of the O antigens of a given serotype. O antigens are the immunodominant part of the lipopolysaccharide molecule in the intact bacterial cell.
