Abstract
We show that the expression of a Yersinia enterocolitica O:8 pYV-encoded type III secretion system was altered in a rough mutant (YeO8-R) due to elevated levels of FlhDC. H-NS might underlie flhDC upregulation in YeO8-R, and the data suggest a relationship between the absence of O antigen and the expression of H-NS.
摘要
我们发现，由于FlhDC水平升高，小肠结肠炎耶尔森菌O:8 pYV编码的III型分泌系统在粗糙突变体（YeO8-R）中的表达发生了改变。H-NS可能是YeO8-R中flhDC上调的原因，并且数据表明O抗原缺失与H-NS表达之间存在关联。
