MeSH Heading: O Antigens
Tree Number(s): D09.698.718.450.600; D10.494.600; D23.050.161.616.525.600; D23.946.123.329.500.600
Unique ID: D019081
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D019081
Scope Note: 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)
