Using the chromato-mass spectrometry of the methylated sugars formed in the hydrolysis of the fully methylated lipopolysaccharide fromYersinia pseudotuberculosis of type IB the nature of the glycosidic bonds between the monosaccharide residues has been established. The hapten formed in the partial hydrolysis of the lipopolysaccharide has also been studied by methylation. The results obtained have confirmed the results of an investigation of the methylated lipopolysaccharide; they have enabled an idea to be put forward of the composition of the repeating unit of the O-specific side chains of the lipopolysaccharide.
