肠出血性大肠杆菌 (EHEC) 产生志贺样毒素 (SLT),这是一种有效的蛋白质合成抑制剂。为了进一步剖析 SLT-II 在疾病过程中的作用,我们构建了大肠杆菌 TUV86-2,它是 EHEC 菌株 86-24 的同基因 SLT-II 阴性突变体。 slt-ii 基因通过自杀载体诱变失活。我们还分离了菌株 86-24 的衍生物,其携带毒素基因的噬菌体被治愈。
Enterohemorrhagic Escherichia coli (EHEC) produces Shiga-like toxins (SLT), potent protein synthesis inhibitors. To further dissect the role of SLT-II in the course of disease, we have constructed E. coli TUV86-2, an isogenic SLT-II-negative mutant of EHEC strain 86-24. The slt-ii gene was inactivated by suicide vector mutagenesis. We also isolated derivatives of strain 86-24 that were cured of the phage carrying the toxin genes.
