Structure of the O-specific polysaccharide of Proteus penneri strain 41 from a new proposed serogroup O62.
O-specific polysaccharide of Proteus penneri strain 41 was studied using 1H- and 13C-NMR spectroscopy, including two-dimensional COSY, heteronuclear 13C,1H-correlation (HETCOR) and one-dimensional NOE spectroscopy, and the following structure of a non-stoichiometrically O-acetylated hexasaccharide repeating unit was established:[structure: see text] where RGlcNAc is 2-acetamido-4-O-[(S)-1-carboxyethyl]-2-deoxyglucose. Cross-reactivity of anti-P. penneri 41 O-serum with other P. penneri strains is discussed, and a new, separate O62 serogroup is proposed which is the next Proteus O-serogroup containing P. penneri strains only.
