A neutral O-specific polysaccharide (O-antigen) was isolated from the lipopolysaccharide (LPS) of the bacterium Proteus penneri 71. On the basis of sugar analysis and 1H- and 13C-NMR spectroscopic studies, including two-dimensional COSY, 13C,1H heteronuclear COSY and ROESY, the following structure of the trisaccharide repeating unit of the polysaccharide was established: →3)-β-d-GlcpNAc-(1→4)-β-d-GlcpNAc-(1→3)-α-d-Galp-(1→ The polysaccharide has the same carbohydrate backbone as the O-specific polysaccharide of P. penneri 19 and both are similar to that of P. penneri 62 studied by us previously. A cross-reactivity of anti-P. penneri 71, 19 and 62 O-antisera with 11 P. penneri strains was revealed and substantiated at the level of the O-antigen structures. These strains could be divided into three subgroups within a new proposed Proteus O64 serogroup containing P. penneri strains only.
