1.有毒,毒力,毒性
2.【医】病毒性;致病力
3.刻毒,恶毒,恶意
1.the quality of being extremely poisonous, infectious, or damaging, or the extent to which a disease or toxin possesses this quality
2.the quality of being bitter, malicious, or hostile
1.In this study, the cell model and mice experiments showed that the virulence of the mutant strain was more inferior to the wild strain.
小鼠腹腔注射实验亦说明，突变体繁殖体毒力弱于野生株。
2.But the essential nature of the pathogen, its personality, its virulence, remain matters of frenetic investigation.
但这种病原体的内在实质、特性、致病力，仍在加紧研究中。
3.This may be potentially due to the difference in biological characteristics of these isolates including their virulence.
这可能同弓形虫不同分离株毒力等生物特性的差异有关。
4.Leptospires with different virulence did not cause significant changes in permeability of endothelial monolayers.
不同毒力的钩体均未引起内皮细胞单层通透性明显改变；
5.The M. tuberculosis strains studied showed no correlation between the virulence, viability, and affiliation to a certain genotype.
结核分枝杆菌菌株的研究显示，没有任何毒力之间的相关性，可行性，以及是否属于某个特定基因型。
6.Up to date little was known about relationship between B. anthracis'virulence genes and their pathogenesis.
迄今为止，炭疽杆菌毒力基因和致病性的关系还不明晰。
7.What you know is that when that bacterium gets into the animal, in this case, a mouse, it doesn't initiate virulence right away.
你们都知道，当细菌进入动物体内，以此为例，对这只老鼠，它并不会马上启动致病机制。
8.Many examples of bacteriophage-encoded virulence factors are known--as such, this finding is not remarkable.
许多例子噬菌体编码的毒力因子是众所周知的-因此，这一调查结果是不显着。
9.Such patients may have a rapidly progressive course, but whether this is due to increased viral virulence or to host factors is not known.
这样的病人可能是快速进展的阶段，但是是否是增加的病毒毒性，还是宿主的因素还是未知的。
10.For humans, we also know that this virus has lost none of its virulence.
不过我们也知道，对于人类，该病毒没有损失其任何致命性。
