Abstract
The structure of the O-polysaccharide of Proteus mirabilis CCUG 10705 (OF) was determined by chemical analyses along with one- and two-dimensional (1)H and (13)C NMR spectroscopy. The polysaccharide was found to contain an amide of D-galacturonic acid with L-alanine and based on the uniqueness of the O-polysaccharide structure and serological data, it was suggested to classify P. mirabilis OF into a new separate Proteus serogroup, O74. A weak cross-reactivity of P. mirabilis OF and P. mirabilis O5 was observed and accounted for by a similarity of their O-repeating units. The following structure of the polysaccharide of P. mirabilis OF was established: [chemical structure: see text]
