O Antigens

More information in Books or onNLM PubMed
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. (From Singleton & Sainsbury, Dictionary of Microbiology and Molecular Biology, 2d ed)      Other names Polysaccharides, O-Specific; Polysaccharide, O-Specific; O Specific Polysaccharides; O Specific Polysaccharide; Bacterial O Antigen; Antigens, O; Antigen, O; Antigen, Bacterial O; O-Specific Polysaccharide; O-Antigens; O Antigen, Bacterial; O Antigen; O-Specific Polysaccharides
