O-polysaccharides of E. coli O28ab, O37, and O100 were found to contain glycerol 1-phosphate and the following structures of their oligosaccharide repeats were established by sugar analysis, Smith degradation (for O28ab), 1D and 2D (1)H, (13)C, and (13)P NMR spectroscopy: [Formula: see text]. Functions of putative glycosyltransferases genes in the O-antigen gene clusters of the strains studied were tentatively assigned based on similarities to genes of other E. coli O-serogroups available from GenBank and taking into account the O-polysaccharide structures established.
