reassortment 英riːə'sɔːtmənt美riːə'sɔːtmənt COCA²⁸⁰¹³⁶⁺⁵iWeb⁶⁰³³⁵ 基本例句 n.重配¹⁰⁰ One fear, however, is that H5N1 might become better at infecting humans by swapping genetic parts reassortment with types of flu virus that already infect humans easily. 但是让人感到恐惧的是, H5N1可以与更容易对人类造成感染的流感病毒交换基因片段重组而得到进化。 yeeyan The avian influenza virus maybe form a new type of reassortment strains through variation of antigens or gene reassortment with human influenza virus. 禽流感病毒有可能通过抗原变异或通过与人流感病毒发生基因重配,形成重配株,从而具备人传人的能力。 www1.chkd.cnki.net The greater viral diversity they found in the swine flu viruses may mean more possible combinations from reassortment. 所以病毒的多样性越高,意味着可能有更多重新排列组合的病毒基因。 www.cvma.org.cn “This is what we call a reassortment between two currently circulating pig flu viruses, ” said Andrew Rambaut, a University of Edinburgh viral geneticist. “我们称其为两种目前流行的猪流感病毒的重配。”英国爱丁堡大学病毒基因学家安德鲁·兰姆伯特说。 yeeyan At least some pandemic viruses are known to have emerged following a reassortment event. 至少,已知在重组发生后,出现了一些大流行性病毒。 who At that point there are not just eight, but 16 viral segments on assembly lines, and the genes start shuffling together in a process called reassortment. 从这个意义上来说,基因组就不只有八段了,其装配线上就有了十六段病毒基因。这些基因在被称为重组的过程中开始慢慢地混合起来。 yeeyan Dynamic gene mutation and the reassortment of genes have been considered as the key factors responsible for influenza A virus virulence and host tropism change. 动态的基因突变和基因重组被认为是流感病毒 A的致病性和宿主趋向性改变的关键因子。 lwheart Each additional human case increases opportunities for the virus to improve its transmissibility, through either adaptive mutation or reassortment. 每增加一例人间病例增强了该病毒通过适应性突变或重组提高其可传播性的机会。 who Genotyping of the PCR- amplified isolate from the confirmed case shows high homogeneity with other H5N1 isolates from poultry in Java, and no evidence of reassortment. 对确认病例的 PCR扩增分离菌进行基因型确定,显示与爪哇禽类的其它 H5N1分离菌具有很高的一致性,没有重新分类的依据。 who In addition, the reassortment of H3N2 human and H1N1 swine influenza virus in pigs was common in recent years. 此外, H3N2人流感病毒和 H1N1猪流感病毒在猪体内的重组是近几年来比较常见的。 lwheart Often this intertwining leads the chromatids of homologous chromosomes to actually exchange corresponding pieces of DNA, a process called crossing- over or genetic reassortment. 缠绕经常导致同源染色体内部的非姐妹染色单体会交换 DNA的部分片段,这个过程叫交叉互换或者是基因重组。 sunbb Sequencing of all eight gene segments found no evidence of genetic reassortment with human or pig influenza viruses and no evidence of significant mutations. 所有八个基因片断的排序未发现证据表明与人或猪的流感病毒发生基因重组,也无证据表明发生显著突变。 who Some currently circulating H5N1 strains are fully resistant to these the M2 inhibitors. However, should a new virus emerge through reassortment, the M2 inhibitors might be effective. 目前流行的一些 H5N1毒株对这些 M2抑制剂有完全的耐药性,然而,如果新的病毒通过重组出现, M2抑制剂可能是有效的。 who Some synkaryons recovered non expected alleles, indicating that macrogenome was integrated into the random site of recipient chromosomes after genome reassortment. 一些结合体具备异常等位基因,说明在受体细胞染色体重排中有大片段随机整合位点。 ahnydxxb The first is a “ reassortment” event, in which genetic material is exchanged between human and avian viruses during co- infection of a human or pig. 第一是“重组”,在人或猪合并感染人类或禽类病毒时发生基因材料交换。 who The virus is produced by a reassortment, in which human- adapted H1N1 swaps genes with an H2N2 bird flu. 这病毒是重组产生的,由人-适应 H1N1与 H2N2禽流感基因互换。 yeeyan Reassortment could result in a fully transmissible pandemic virus, announced by a sudden surge of cases with explosive spread. 重组可导致完全具传播可能的大流行病毒,出现爆炸性传播,突然造成病例激增。 who |
