Among them 84.5% what trojan and postern virus occupy overall virus, gross is about 770 thousand.

其中木马和后门病毒占总体病毒的84.5%，总数约为77万。

Pay close attention to virus:"TA of Ceckno postern mutation " it is a postern virus.

关注病毒："Ceckno后门变种TA"是一个后门病毒。

For instance, in 2003 an outbreak of monkeypox affected around 20 people in the US midwest, traced to imported Gambian pouched rats from Africa.

2003年，美国中西部地区的约20人感染了一种"猴痘"病毒，这种病毒源于从非洲进口的一批冈比亚巨鼠。

The results showed that Non-haemagglutinating activity was showed in the isolate. In agar diffusion test,there was a clear precipitin band formation to anti-IBDV specific serum. 28-day-old chicks inoculated with the isolate showed disease,and the isolate was recovered from the tissues of these chickens. The 1 041bp specific fragment were amplified by RT-PCR with sequence-specific primers based on IBDV VP3 gene. The VP3 gene shared 97.7%~98.2% nucleotide identities to very virulent IBDV,97.7%~95.2% nucleotide identities with classical strains from seqiemce analysis.

结果表明，该分离病毒无血凝性，在琼脂扩散试验中能与抗IBDV特异性血清出现1条清晰的白色沉淀线；人工感染28日龄雏鸡出现与临床一致的病变，并回收到病毒；应用针对IBDVVP3基因的特异性引物进行RT-PCR，能扩增到长度为1041bp的特异性目的片段；序列分析发现分离毒VP3基因与IBDV超强毒和经典毒株的核苷酸同源性分别为97.7%~98.2%和95.2%。

Recruitment of the 43 S preinitiation complex by the HCV IRES involves a mechanism distinct from that of eukaryotic mRNAs with 5 capped structure.

其5 '端具有高次构造可以经由内部起始机制进行病毒多蛋白质之直接转译作用C 型肝炎病毒5 '端IRES 可直接结合435 前转译起始复合体有别於一般真核细胞戚NA 含有5 ' cap 之转译起始机制。

This is a new virus, we need to do everything possible to prevent the virus.

这是一个新的病毒，我们需要尽一切可能来阻止这种病毒。

As an ideal prime immunization vaccine,the DNA vaccine has the advantages of high purity,continuous expression of antigens with low dose, repeatable immunization and inducement of memory CTL with high titer.Similarly, recombinant virus can not only highly express the target antigen,simulate the inducement process of virus infection on body immunity,and induce various cytokines,but also be beneficial to the interaction of high-affinity antibodies with T cell receptors,and the generation of Th1 reaction and CTL reaction.

DNA疫苗抗原纯度高，持续表达低剂量的抗原，可多次重复免疫以及诱导高效价记忆性细胞毒性T淋巴细胞反应，是理想的用于初次免疫的疫苗；重组病毒能高效表达目的抗原，模拟病毒感染诱导机体免疫的天然过程，能诱发多种细胞因子，而且有利于高亲和性抗体和T细胞受体的选择，可以有效地产生Th1型和CTL反应。

Since Lacromin is derived from plants, it is free of any viral or prion containment risks.

因为Lacromin来自植物，所以没有任何病毒和或者朊病毒污染的危险。

A sandwich LAB-ELISA wa s developed to detect Pseudorabies virus on the basis of species-specific monoclonal antibodies in this study.

在伪狂犬病病毒种特异性单克隆抗体的基础上建立了检测该病毒抗原的单抗夹心LAB-ELISA方法。

Porcine parvovirus and pseudorabies virus are the main causes of infectious reproductive failure in swine.

猪细小病毒和伪狂犬病毒均是引起母猪繁殖障碍的主要病原，猪细小病毒的危害主要表现为，导致初产母猪或血清学阴性的经产母猪发生繁殖障碍，其它年。。。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
