An acidic O-specific polysaccharide was obtained by mild acid degradation of the Proteus penneri 8 lipopolysaccharide and found to contain D-glucose, D-galacturonic acid, 2-acetamido-2-deoxy-D-glucose, 2-acetamido-2-deoxy-D-galactose, 2-acetamido-2,6-dideoxy-L-galactose (L-FucNAc) and 2-aminoethyl phosphate (PEtn) in the ratios 2 : 1 : 1 : 1 : 1 : 1. 1H and 13C NMR spectroscopy was applied to the intact and dephosphorylated polysaccharides, and the following structure of the hexasaccharide repeating unit was established: The O-specific polysaccharide has a unique structure, and, accordingly, we propose for P. penneri 8 a new Proteus O67 serogroup, in which this strain is at present the single representative. The nature of epitopes on LPS of P. penneri 34, P. mirabilis O16, P. mirabilis O23 and P. vulgaris O22, which cross-react with O-antiserum against P. penneri 8, is discussed.
