virulence

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

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

The sequences and secondary structures of IRES are compared.Interaction between IRES and translation initiation factors and relation with virulence of FMDV is summarized.

本文对IRES一、二级结构进行了比较，对IRES与翻译起始因子相互作用以及对病影响作了综述。

Signal transmission can be quenched by inhibition of N-acyl-homoserine-lactone, leading to breaking the initial of pathogenic genes transcription and the expression of virulence.

目前发现参与这种信息传递最普通信号分子是N-脂酰高丝氨酸内酯。

Enterococcus faecium generally is considered to be a species with little virulence, at least in some measure, because it was found to be responsible for only 10% of enterococcal infections in human.

屎肠球菌较弱,过去十多年内,屎肠球菌所引起感染有所上升,由来不到10%,上升到30%～40%。
