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.
作者展示了宋内志贺氏菌I期、II期以及R型纯化脂多糖（LPS）的化学单糖组成和超微结构的研究结果。LPS制剂中的脂质含量随着从S型向R型的转变而增加。II期LPS中的半乳糖含量低于I期LPS，并且在R型LPS中完全不存在。负染色显示，LPS从S型向R型的解离增加。发现II期LPS和R型LPS的大分子聚集体之间存在显著相似性。
