不致病的

In this investigation, we found that mucoid phenotype and magA were not the most important factors to cause KP PLA complicated with metastatic infection.

由我们所搜集的临床克雷白氏肺炎杆菌菌株中发现，在其造成化脓性肝脓疡并发转移性的感染，高黏性与MagA可能都不是最重要的致病因子。

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〕。

LT and ST are the main enterotoxins of enterotoxigenic \$Escherichia coli \$found in clinical isolates, and CS3 (the common antigen in the CFA/Ⅱ family of fimbrial antigens) is one of the most prevalent antigens of colonization factors.

不耐热肠毒素和耐热肠毒素是产肠毒素大肠杆菌的主要致病因素，CS3为该菌的优势定居因子，是定居因子CFA/II菌毛抗原的共有抗原组分。

The currently knowledge about pathogenic molecular mechanism of leptospira is not enough.

目前，对钩体的致病及免疫分子机理的认识不甚清楚。

Conelusion:Missense mutation of Tyr486Asp in Exon 5 of UGT1A1 gene is the pathogenic factor of the CN Ⅱ case in the family and recessively inherited.

Tyr486Asp突变是本例CN—Ⅱ家系的致病性基因，该突变不影响UGT1A1基因启动子区苯巴比妥酸的应答元件，其遗传规律符合常染色体隐性遗传。

Missense mutation of Tyr486Asp in Exon 5 of UGT1A1 gene is the pathogenic factor of the CNⅡ case in the family and recessively inherited. The mutation has no influence on the response elements of phenibarbital in the promoter region.

Tyr486Asp突变是本例CN-Ⅱ家系的致病性基因，该突变不影响UGT1A1基因启动子区苯巴比妥酸的应答元件，其遗传规律符合常染色体隐性遗传。

An affected male transmits the disease-causing mutation to all of his daughters and none of his sons.

男性患者将致病突变传递给他所有的女儿，不传递给他的儿子。

German-Swiss alchemist and physician who introduced the concept of disease to medicine.

帕拉塞尔苏斯，菲利浦斯欧雷奥卢斯1493－1541德国瑞士籍炼金术士和医生，他把疾病这一概念引进医学，认为疾病是分割身体的外用药剂的结果，而不是体内失调，并主张使用药物抵抗致病药剂
