The molecular basis for the virulence of this virus is still poorly understood. We characterized two H5N1 subtype viruses, A/mallard/Huadong/Y/2003 is nonpathogenic to mallard whereas A/mallard/Huadong/S/2005 is highly pathogenic to mallard.

我们对从野鸭分离到的H5N1 亚型禽流感病毒的生物学特性进行鉴定，其中A/mallard/Huadong/Y/2003是对麻鸭无致病性病毒，而 A/mallard/Huadong/S/2005是对麻鸭高致病性病毒。

Nevertheless, the eight virus isolates that were nonpathogenic in ducks replicated and transmitted efficiently to naive contacts, suggesting that highly pathogenic H5N1 viruses causing minimal signs of disease in ducks can propagate silently and efficiently among domestic and wild ducks in Asia and that they represent a serious threat to human and veterinary public health.

该现象提示高致病性流感毒株H5N1能够在野鸭或家禽体内迅速、隐匿复制而无明显表现，对人或家禽的健康安全构成严重威胁。您翻译的质量真不错，感谢您的参与我领第4单元。已完成。4单元译文。doc (27.5k)第10单元吧，可是我打不开，乱码，麻烦楼主发给我，邮箱已pm我领第七单元吧！我领第九单元吧！第七单元完成！

Objective To study the relationship between DNA fragments in ENV gene of SIVmac and viral replicating ability. Methods Reciprocal recombinants were constructed by replacing the clonable DNA fragments of ENV region of the nonpathogenic SIVmac142 clone with the pathogenic SIVmac 239 clone.

猴免疫缺陷病毒(simian immunodeficiency viruses SIV)是一组在致病性和毒力方面具有多样性的灵长类动物病毒，其中，SIVmac239克隆感染的猴表现为与人类AIDS相似的疾病，称之为致病株，而SIVmac142克隆仅引起猴发生病毒血症，不发生临床综合征，称之为非致病株〔1〕。
