Abstract

The authors noted a different influence upon the virulence of Sh. flexneri (determined by keratoconjunctival test) of transmission of different alleles of the strA-gene (A1, A2, A40, A60). There was revealed no correlation between the extent of the changes in virulence and the extent of capacity ot the limiting of suppression in donor strains.

摘要

作者们注意到，strA基因不同等位基因（A1、A2、A40、A60）的传递对弗氏志贺菌毒力（通过角膜结膜试验测定）有不同影响。毒力变化程度与供体菌株抑制限制能力程度之间未发现相关性。
