Abstract

The chemical and serological properties of lipopolysaccharides isolated from the S form and from the R form of cholera vibrios were compared. It was found that the S-R mutation of cholera vibrios involves total elimination of the two component amino sugars of S-form lipopolysaccharides, i.e. quinovosamine and perosamine. This elimination resulted in the loss of O-specificity of S-form lipopolysaccharides and concomitant appearance of strong serological cross-reactivity, in the passive-haemolysis-inhibition test, among R-form lipopolysaccharides regardless of the serotypes (Inaba and Ogawa) of their S parent strains.

摘要

比较了从霍乱弧菌S型和R型分离出的脂多糖的化学和血清学特性。发现霍乱弧菌的S-R突变涉及S型脂多糖的两种组成氨基糖,即奎诺糖胺和过氧胺的完全消除。这种消除导致S型脂多糖的O特异性丧失,并在被动溶血抑制试验中,R型脂多糖之间出现强烈的血清学交叉反应,而不论其S亲本菌株的血清型(稻叶型和小川型)如何。
