virulence

音標發(fā)音

Then we can really start to look at the genetic variation within the species and gain insight into some of the genes involved in drug resistance or virulence.
然后我們才能真正地開始尋找該物種的種內遺傳變異，并獲得和耐藥性或毒力有關的一些基因的信息。
For all its virulence, the latter spreads most easily when animals are in close contact with each other, so restricting the movement of animals isolates the virus and stops it from spreading.
因為對于口蹄疫及它所有的毒性而言，病毒最容易的傳播途徑是通過動物之間的緊密接觸；所以限制動物的自由移動就可能隔離病毒、斷絕傳播源。
Without that information, it is also impossible to determine the new disease’s virulence, fatality rates and so on.
而且如果沒有這些診斷信息，也根本不可能決定這種新型病毒的毒性及致死率等。

HIV's ability to replicate (known technically as its virulence) may have decreased since the start of the pandemic.
ECONOMIST: In one part of Europe, HIV may be getting less virulent
But his apparent lack of negotiating space reflects both his own weakness and the virulence of anti-American sentiment among ordinary Pakistanis.
ECONOMIST: The NATO summit

Virulence is great bitterness and hostility.
The virulence of a disease or poison is its ability to harm or kill people or animals.

毒力
Virulence test showed the isolate was highly virulent(LD50=5×103CFU).
毒力試驗顯示，分離株對小鼠的LD50為5×103CFU,具有很強的致病性。
毒性
A lack of correlation between the virulence and RAPD dissimilarity matrices was observed, indicating the independence of DNA polymorphism from virulence diversity.
結果表明，DNA多態(tài)性與毒性多態(tài)性之間沒有相關性。
致病力
In order to pinpoint the key amino acids that affected virulence, we generated many PA mutant viruses and tested them on ducks.
為進一步在PA上尋找其影響致病力的關鍵位點,我們拯救出一系列PA突變的病毒,并且做了感染家鴨實驗。

毒力
The expression of virulence genes of Shigella is temperature-dependent.
痢疾桿菌毒力的表達是溫度相關的。
耐藥性
Genetic mutation in viruses are usually associated with escape of host immune responses, developing drug resistance, modification of virulence and patterns of epidemiology of diseases.
病毒的基因變異與逃避機體免疫應答、出現(xiàn)耐藥性、改變致病性和引起疾病流行等有關。
