Structural and immunochemical studies on the O-specific polysaccharide of Proteus penneri strain 15.
On the basis of sugar analysis and 1H- and 13C-NMR spectroscopy, it was shown that the O-specific polysaccharide of Proteus penneri strain 15 has a trisaccharide repeating unit, including an acetal-linked pyruvic acid residue, and is structurally identical to the capsular polysaccharide of Proteus vulgaris strain ATCC 49990. Serological studies supported this conclusion and demonstrated the presence in the homological antiserum of both anti-core and anti-O chain antibodies reacting with a lipopolysaccharide (LPS) epitope containing N-acetylglucosamine and galactose residues.
