A toxin extracted from heat-inactivated, alkaline-treated Shigella flexneri 2a showed biological properties similar to those of Shigella dysenteria 1 toxin. The S, flexneri 2a toxin was lethal to mice, enterotoxic for ileal loops of rabbits, and cytotoxic for HeLa cells. A serological relationship between S. flexneri 2a and S. dysenteriae 1 toxin was shown with cross neutralization tests.
从经热灭活和碱处理的福氏志贺菌2a中提取的一种毒素,其生物学特性与痢疾志贺菌1型毒素相似。福氏志贺菌2a毒素对小鼠具有致死性,对兔回肠袢具有肠毒性,对HeLa细胞具有细胞毒性。交叉中和试验表明福氏志贺菌2a与痢疾志贺菌1型毒素之间存在血清学关系。
