毒力岛

There have been many studies on the structure and function of the high pathogenicity island since it was first discovered to be located on Yersinia.

近年来，人们发现了耶尔森菌强毒力岛，并对其结构与功能进行了大量研究。

Objective To study whether the genes of HPI island of Yersinia is existed in enteric Shigelloid toxin producing and invasive Escherichia coli (ESIEC).

目的研究肠产志贺样毒素且具侵袭力的大肠杆菌（ESIEC）菌株是否含有耶尔森菌的HPI（毒力岛）基因。

Conclusions Environmental modulation of gene expression and pathogenesis inY. pestis, especially the island.

结论鼠疫菌基因的表达和致病性受环境因素调节，特别是毒力岛。

They are not only synergic in biologic activities but also interactive in molecularity, which is regulated by the genes of virulence island.

各毒力因子不仅在生物学活性上具有协同作用，而且在分子水平上也是相互影响，受毒力岛上调控基因调节。
