[Study of a lipopolysaccharide from Yersinia pseudotuberculosis of the IVA serotype]

The comparative studied on lipopolysaccharides from Yersinia pseudotuberculosis IVA serovar, strains 32 and 31D, have been conducted. The identity of the lipopolysaccharides isolated from these strains has been shown. The structural pattern of the repeating unit of the O-specific side chain of the lipopolysaccharide has been suggested: (Formula: see text)
