• 毒力

  Virulence test showed the isolate was highly virulent(LD50=5×103CFU).

  毒力试验显示，分离株对小鼠的LD50为5×103CFU,具有很强的致病性。

• 毒性

  A lack of correlation between the virulence and RAPD dissimilarity matrices was observed, indicating the independence of DNA polymorphism from virulence diversity.

  结果表明，DNA多态性与毒性多态性之间没有相关性。

• 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.

  为进一步在PA上寻找其影响致病力的关键位点,我们拯救出一系列PA突变的病毒,并且做了感染家鸭实验。

医药科学

• 毒力

  The expression of virulence genes of Shigella is temperature-dependent.

  痢疾杆菌毒力的表达是温度相关的。

• 耐药性

  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.

  病毒的基因变异与逃避机体免疫应答、出现耐药性、改变致病性和引起疾病流行等有关。
