代表株 meaning in English
representative strain
Examples
- Eighteen h9n2 influenza viruses were selected for further antigenic and genetic analysis
从中选取18株hgnz病毒代表株进行下一步的分子生物学工作。 - Twelve h9n2 and two h9n1 influenza viruses were selected for further antigenic and genetic analysis
从中选取12株h9n2 ， 2株h9n1病毒代表株进行下一步的分子生物学工作。 - Genomic analysis indicated that prrsv has two major genotypes , the european represented by strain lv and the north american represented by strain vr - 2332
根据基因型差异， prrsv可分为北美洲型( vr - 2332为代表株)和欧洲型( lv为代表株) 。 - Sequence comparison indicated that the nucleotide homologies between the ha gene and those from eight other h3 subtype sfv isolates from china are over 95 % , and nucleotide identities between h3 sfv isolates in china and a typical h3 subtype avian influenza virus ( aiv ) strain dkuk1 - 63 are 95 % to 100 % . these might tell us that the ha gene of all h3 subtype sives isolated in china was originally from aiv although the vaccine based on ha do not protect against different subtype of influenza virus , it can provide favorable resistance to infection with antigenic variants within a subtype
通过与其它7株国内siv分离株和6株genebank中的h3流感病毒ha序列比较分析，结果表明分离自我国不同地区的8株h3siv核苷酸序列同源性均在95 %以上，且与禽流感病毒( aiv )经典代表株dkuk - 63序列同源性在95 - 100 %之间，证实我国h3sivha基因来源于禽的流感病毒。 - The result showed that the homology rate of pila gene among the 5 avian pathogenic e . coli strains tested and one human e . coli were from 89 . 8 % to 91 . 1 % , and the homology rate of amino acid were from 88 . 5 % to 91 . 8 % . the homology rate of pila gene sequence among 5 avian pathogenic e . coli strains tested and avian pathogenic e . coli reported ( serotype o1 , o2 , o78 ) were from 87 . 8 % to 90 . 2 % , and the homology rate of amino acid were from 84 . 6 % to 91 . 2 % . there had homology in avian pathogenic e . coli . there had some common antigen side in type 1 pili of avian pathogenic e . coli
结果表明：运用msha法检测1型菌毛的检出率为80 ( 36 45 ) ， pcr法的检出率为95 . 5 ( 43 45 ) ， pcr方法用于1型菌毛的检测比msha更加敏感、快速、特异性强；选择5株优势血清型鸡源致病性大肠杆菌代表株( o _ ( 89 ) ， o _ ( 119 ) ， o _ ( 141 ) ， o _ ( 127 ) )的1型菌毛pila基因的pcr扩增片段经纯化后，分别定向克隆到puc18质粒的多克隆位点，构建了含有目的基因片段的克隆质粒，并转化到dh5株大肠杆菌载体菌中，筛选获得阳性克隆菌株。
