In eukaryotic cells,Toll-like receptors in endosomal membrane were show to recognize viral RNA in endosome and thereby initiate innate immunity pathways for virus resistance.By contrast,a cytosolic RNA receptor protein, RIG-Ⅰ(retinoic acid inducible gene-Ⅰ),has recently been identified for recognition of the viral RNA.

在真核生物体内，除了定位于内吞体膜上的TOLL样受体能够识别入侵机体的病毒RNA，启动机体抗病毒的固有免疫反应外，近年来发现了另一种能够识别病毒RNA的细胞质内受体——RIG-Ⅰ。

Several dozen researchers, led by Rebecca Garten of America's Centres for Disease Control and Prevention, sequenced full or partial genomes of 76 samples of the new virus, which has afflicted almost 13,000 people around the world so far.

在四月份出现了一种具有大规模流行病爆发可能性的流感病毒，我们一般把它称之为&猪流感&，这是因为这种病毒和存在于猪体内的A/H1N1病毒类似。

Porcine Rotavirus belongs to the family reoviridae. It is one of the major pathogens of diarrhea in piglets and causes of significant losses in graziery worldwide.

猪轮状病毒(Porcine Rotavirus，PRV)属于呼肠病毒科轮状病毒属，是引起仔猪病毒性腹泻的主要病原之一，该病在世界范围内分布，给世界各地的畜牧业造成严重的损失。

HaNPV is the earliest commercial baculovirus insecticide in China and about 100, 000 hectare cotton farmland had been used such insecticide to prevent Heliothis armigera by the end of 1999. Many aspects of HaNPV such as the isolation and identification of different virus strains, bioassay of their toxicity, infectivity and duplication in culture cells, genome sequencing and some functional genes have been researched.

国内已对HaNPV进行了多方面的研究，包括病毒株的分离鉴定、形态特征、病毒生物活性测定、离体细胞感染和复制、测序和功能基因研究，基因工程病毒杀虫剂的构建等；但对其复制侵染与宿主细胞互作的分子机理，目前仍缺乏足够且深入的了解。

Research shows that of the human AIDS virus infection and virus cells have inhibitory effect on the treatment and prevention of AIDS was very useful; also Herpetic inflammation lips and mouth ulcers significantly, with broad-spectrum anti-virus capabilities.

研究表明对人类艾滋病病毒的感染和病毒细胞的活性都具有抑制作用，对AIDS的治疗和预防非常有用；还对疱疹性口唇炎和口腔溃疡效果显著，具有广谱抗病毒的能力。

According to introducing,"Webpage virus downloads implement " it is a vermian virus, the meeting after moving deletes systematic file Svchost.exe, it builds homonymic virus file below systematic catalog later.

据介绍，&网页病毒下载器&是一个蠕虫病毒，运行后会删除系统文件svchost.exe，之后它在系统目录下建立同名的病毒文件。

We have developed a method for detection of Hypodermal and hematopoietic necrosis baculovirus by polymerase chain reaction.

皮下和造血器官坏死杆状病毒［1］、对虾杆状DNA病毒［2］和白斑杆状病毒［3］是近年来引起全球对虾暴发性死亡的病原。

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。

We don't have a particular virus that we're thinking about," she says,"but we're wondering if there might have been some viruses around in the '30s,'40s and '50s that might be immunologically similar to the one we're seeing now.

我们所面对的并非是一种特殊的病毒，&她说，&这些病毒很有可能在30年代、40年代和50年代便已出现过，在免疫学上来说它们和现今出现的病毒是类似的。

FMDV usually causes persistent infection or inapparent infection that can also occur in vaccinated animals following contact with the virus,which will influence the diagnostic techniques and the preventive measures that need to be taken.

口蹄疫病毒是小RNA病毒科口蹄疫病毒属的成员，该病毒感染动物尤其是反刍动物以后，会形成无症状的持续性感染或隐性感染，注射疫苗的动物当再次接触新病毒时，也会成为隐性带毒者，从而给口蹄疫的诊断和防制带来严重的影响。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
