1) titer
强毒
2) virulent duck plague virus
鸭瘟强毒
1.
The propagation characteristics of virulent duck plague virus(DPV)in duck embryo fibroblast(DEF)were studied by the method of light microscopy observation of DEF cell culture monolayer,electron microscopy observation of infected DEF cell culture,real-time PCR detecting virus propagation.
通过细胞培养物光学显微观察、细胞超薄切片研究、定量PCR检测技术对鸭胚成纤维细胞中鸭瘟强毒的增殖特性进行了研究。
3) Virulent strain
强毒株
1.
After 10 passages through 1 day old SPF chicks with IBV D971,a virulent strain IBV D971J was developed.
用腺胃病变型鸡传染性支气管炎病毒分离株 IBV-D971株接种 1日龄 SPF鸡 ,连续传 1 0代后 ,培育出了腺胃病变型鸡传染性支气管炎强毒株 IBV-D971 J株。
4) High pathogenicity island
强毒力岛
1.
As a member of PAIs,high pathogenicity island (HPI) encoding a iron uptake system mediatd by siderphore yersiniabactin was first identified in high pathogenic Yersinia and is greatly important genie unit for Yersinia.
耶尔森菌属的强毒力岛(high pathogenicity island，HPI)编码铁载体耶尔森菌素介导的铁摄取系统，是耶尔森菌毒力的重要遗传单元。
5) very virulent IBDV
超强毒株
1.
The result indicated that YL051 belonged to very virulent IBDV(vvIBDV),YL052 m.
结果表明:分离株YL 051属IBDV的超强毒株(vvIBDV),而YL 052株既具有强毒株的特征即七肽区(SW SA SG S)和279D,但同时也具有284T的弱毒株特征,可能属于介于强毒株与弱毒株之间的一个中间型。
6) very virulent strain
超强毒株
1.
An isolated strain HN01 of Infectious Bursal Disease Virus (IBDV),a suspected very virulent strain,was purified and inoculated into SPF chickens,which were proved infected 36 h later with lethal rate more than 70% and incidence rate 100%.
经血清学试验、毒力试验、鸡胚接种试验、分子生物学和电镜形态学观察均证明该分离物为超强毒株,从而证明河南省鸡群中存在不同于IBDV一般强毒株、经典株和变异株的超强毒株。
