title: The structure of the O-specific polysaccharide of Proteus penneri 52.
abstract: An acidic O-specific polysaccharide isolated from Proteus penneri 52 contains D-galacturonic acid, 2-acetamido-2-deoxy-D-glucose, and 2-acetamido-2-deoxy-D-galactose in the ratio 1:2:2. On the basis of sugar analysis and NMR spectroscopy, which included one-dimensional TOCSY, two-dimensional COSY, heteronuclear 13C, 1H-COSY, and rotating-frame NOE spectroscopy, the following structure of the pentasaccharide repeating unit of the O-specific polysaccharide was established: [sequence: see text] Cross-reactivity of the anti-P-penneri 52 O-serum with other strains of P. penneri isolated in Germany. Poland, USA, and Canada is discussed and a new Proteus serogroup is proposed.
