title: [Features of the monosaccharide composition and ultrastructure of lipopolysaccharides of different forms of Shigella sonnei].
abstract: The authors present the results of study of chemical monosaccharide composition and the ultrastructure of purified lipopolysaccharides (LPS) of the I and the II phases and the R-form of Sh. sonnei. The amount of lipids in LPS preparations increased with the change from S- into R-form. Galactose content in LPS of the II phase was less than in LPS of the I phase, and it was absent entirely in LPS of R-form. It was demonstrated by negative contrasting that LPS dissociation increased with S leads to R dissociation. A marked similarity was found between macromolecular aggregates of LPS of the II phase and of R-form.
