Strong cross-reactions are described between Proteus mirabilis strains having the same structures of repeating units of their O-specific polysaccharides. These strains are used in routine diagnosis of ricketsiae.

In this paper we present the structure and describe serological properties of the O-specific polysaccharide of Proteus mirabilis O13 lipopolysaccharide, which contains a unique component, an amide of D-galacturonic acid (D-GalA) with an unusual amino acid N-[(R)-1-carboxyethyl]-L-lysine (alaninolysine, AlaLys). Selective chemical degradations of either GalA or AlaLys resulted in the loss of the serological reactivity of the polysaccharide with anti-O serum against P. mirabilis O13. Neither synthetic stereoisomers of AlaLys nor the isolated amide of GalA with AlaLys inhibited the reaction of the O-antiserum with the homologous lipopolysaccharide. The O-antiserum did not cross-react with the lipopolysaccharide of Providencia alcalifaciens O23 containing an amide of D-glucuronic acid with AlaLys. These data showed that both uronic acid and amino acid components of the amide play an important role in manifesting the P. mirabilis O13-specificity, but the full specific epitope also includes also another OPS component(s). A cross-reactivity of anti-O13 serum with some other P. mirabilis strains was observed and attributed to a common heat-stable antigen(s) different from the lipopolysaccharide.

Structural and serological characterization of the lipopolysaccharide from proteus penneri 20 and classification of cross-reacting proteus penneri strains 10, 16, 18, 20, 32 and 45 in proteus serogroup O17

O-specific polysaccharide (O-antigen) of the lipopolysaccharide of Proteus penneri 20 was studied using sugar analysis along with various one- and two-dimensional NMR spectroscopy techniques. The structure of the polysaccharide was established. It has the same carbohydrate backbone structure as that described earlier for P. penneri 16, in which the positions of the O-acetyl groups have not been determined. P. penneri 20 O-antiserum showed a strong cross-reactivity with the lipopolysaccharides of P. penneri 10, 16, 18, 32, 45 and P. mirabilis O17. These data enable classifying these strains together with P. penneri 20 in one Proteus serogroup, O17.
