Methods According to change figures of characteristic water level in typic years at Datong and Naming water hydrometric stations.

方法根据大通水文站及南京水文站建坝前后各典型年特征水位的变化值，以及江洲滩家畜上滩活动、家畜感染情况、滩地野粪污染、江洲滩钉螺及感染性钉螺分布的现况调查，推测三峡建坝后水位变化对家畜活动和感染以及滩地钉螺和感染性钉螺分布的影响。

The trails were carried on Drosophile and Hypodermosis in yaks.

试验表明，在饲料中添加1μg/mL他汀类药物，果蝇的生长发育就可被有效抑制；感染皮蝇蛆的牦牛一次口服100mg他汀类药物，感染率成功率可从80%下降到40%，感染强度从6.8下降到2.4。

Medical care and health institutions, anti-epidemicagencies and units engaged in the experimentationofpathogenic microorganisms must rigorously implementthe management system and the operation procedures stipulated by the health administration department under the State Council to prevent the iatric infection of infectious diseases, inside-hospital infection, laboratory infection and the spread of pathogenic microorganisms.

第十五条医疗保健机构、卫生防疫机构和从事致病性微生物实验的单位，必须严格执行国务院卫生行政部门规定的管理制度、操作规程，防止传染病的医源性感染、医院内感染、实验室感染和致病性微生物的扩散。

In addition, baculovirus are noninfectious to vertebrates, and their promoters have been shown to be inactive in mammalian cells. Futhermore, the expression level of some recombinant proteins is up to 1000 mg/L. Finally, recombinant proteins are soluble and antigenically, immunogenically and functionally similar to their authentic counterparts. In this article, we used the transfer vector pBlueBac of AcNPV (Autographa californica Nuclear Polyhedrosis Virus) to construct the recombinant baculovirus AcNPV-GM-CSF by in vivo recombinantion.

本文中，我们首先利用苜蓿夜蛾核型多角体病毒带β-Galactosidase 基因标记的非融合蛋白基因转移载体pBlueBac，通过细胞内同源重组的方式将hGM-CSF基因成功地插入病毒AcNPV的基因组中。hGM-CSF基因编码信号肽和完整的氨基酸序列。hGM-CSF基因在感染重组病毒的草地夜蛾培养细胞Sf9中得到表达，感染后的Sf9细胞培养液能刺激人骨髓细胞在体外形成典型的集落，表达水平可达2.7〓CFU／ml。

Before intervention, FSWs knew little about the knowledge of STDs and HIV/AIDS, and were imperceptive about the risk of being infected with HIV. There were quite a lot mistakes about their condom using. HIV related high-risk behaviors also existed. Comprehensive intervention need to be carried out urgently, widely and deeply in this population.

1。干预前性服务小姐性病、艾滋病知识水平低，对感染艾滋病的危险认识不足，在安全套的使用中存在许多错误，存在感染艾滋病的高危行为，需及时、广泛、深入地开展针对该人群的艾滋病综合干预措施。

Therefore, how to determine inapparent infection and differentiate between infected and vaccinated animals is required for FMD prevention and control.

因此，如何判断隐性感染动物以及区别注苗动物和自然感染动物是口蹄疫防制技术研究的一项重要内容。

Inapparent or subclinical infections occur when too few cells are infected to cause clinical symptoms.

隐性或亚临床感染发生在感染细胞数量很少以至于不引起临床症状。

Objective To determine whether there exist the inapparent infection or subclinical infection of severe acute respiratory syndrome associated coronavirus among the patients with clinical fever.

目的了解临床发热患者中是否存在严重急性呼吸综合征冠状病毒隐性感染或亚临床感染。
