所述新型嵌合的传染性DNA克隆及其衍生的有毒力的嵌合病毒是用非致病性PCV1构建的，其中，致病性PCV2的免疫原性ORF基因取代了非致病性PCV1的基因，优选是在相同的位置上取代。

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！

Methods Real-time PCR, using the primer-probe specific for the yst gene, was applied to detect the pathogenic （7 serotypes） and nonpathogenic （ 5 serotypes） Yersinia enterocolitica, other species of Yersinia （8 types）, and other enteric bacteria （8 types）.

应用针对致病性小肠结肠炎耶尔森菌染色体上yst基因而设计的特异引物和探针进行实时定量聚合酶链反应，检测致病性（7种血清型）和非致病性（5种）小肠结肠炎耶尔森菌、耶尔森菌属内的其他菌种（8种）及其他肠道细菌（8种）。

A/duck/Guangxi/22/2001 (DKGX/22) is nonpathogenic in mice, whereas A/duck/Guangxi/35/2001 (DKGX/35) is highly pathogenic.

我们用拮抗基因去产生一系列单一的综合基因，包括从DKGK/22中分离的一个及DKGX/35保留的7个基因片断，我们发现基因DKGK/22中的PA，NA，和NS某种程度能够消弱DKGX/35的致病性，但是DKGK/22病毒中的PB2能大大消弱DKGX/35病毒致病性，并且PB2的701位点天冬酰氨代替天冬氨酸在这种功能中起着主要作用。

Aeromonas hydrophila BA6 was identified as a nonpathogenic agent,while the other seven strains (BA1,BA3,BA10,BAH,BA15,BA16 and XA23) were pathogenic. However,there would be difference in virulence among the strains of the same or different species.

结果表明嗜水气单胞菌BA6株为非致病株，其余7株嗜温气单胞菌为致病株，但细菌的毒力大小在不同表型种间和不同菌株间都存在差异。

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〕。

In a very long incubation period, although no infection symptoms, appearance as an ordinary person, but the body's immune system by HIV continues to damage to the immune system can no longer maintain the minimum defense capability, a variety of normal People will not cause the disease so that patients will be pathogenic microorganisms in the conditions of the infection, caused brain, lungs, gastrointestinal tract and other parts of the disease and symptoms.

在很长的潜伏期中，感染者虽然没有自觉症状，外表一如常人，但全身免疫系统仍在继续受到艾滋病病毒的破坏，到免疫系统功能再也不能维持最低的防御能力时，多种对正常人不会引起疾病的病原微生物便会使患者发生条件性感染，引起脑、肺、胃肠道和其他部位的病变及症状。

In a very long incubation period, infected Although there is no subjective symptoms, appearance, as ordinary people, but systemic immune system by the AIDS virus continues to damage to the immune system can no longer maintain the minimum defense capability, a variety of normal will not cause disease pathogenic microorganisms would make the conditions of patients with infection caused brain, lungs, gastrointestinal tract and other parts of the lesions and symptoms.

在很长的潜伏期中，感染者虽然没有自觉症状，外表一如常人，但全身免疫系统仍在继续受到艾滋病病毒的破坏，到免疫系统功能再也不能维持最低的防御能力时，多种对正常人不会引起疾病的病原微生物便会使患者发生条件性感染，引起脑、肺、胃肠道和其他部位的病变及症状。
