为研究病毒的核酸分子结构与其致病性的关系，本研究选取了在致死率上不同的4个ibdv野毒株，比较了它们的vpz基因高变区共494个碱基序列。 | | 2. | These results showed that the three isolates were infectious bursal disease virus . the full - length cdna of the genomic segment a of two viruses , one virulent field strain ibdv zj2000 and one attenuated strains ibdv jd1 , were amplified in a single step procedure by long - accurate reverse - transcription polymerase chain reaction ( la - pcr ) , cloned into pgem - t easy vector , and sequenced
分别以传染性法氏囊病病毒zj2000株(野毒株)和jd1株(弱毒株)基因组dsrna为模板，采用long - accuratert - pcr ( la - pcr )一步法扩增并克隆了两株病毒的基因组a节段全长cdna 。 | | 3. | The result shows that the high degree of homology of e2 sequences and 426 residues amino acid sequences existed in the strain hclv , hcv - jn , hcv - yc , fc and the epitopes between the four strains are not variable obviously by analysising the variation of some main amino acid residues substitutions of e2 major antigenic domains , confirming initially immunization with hcv vaccine strain can resist challenging of field strains
结果发现， hclv与fc间核苷酸及氨基酸序列的同源性分别为98 . 3 、 99 . 2 ；两个野毒株与hclv和fc株之间的同源性也分别在98以上，与alfort株的同源性最低，分别在83 、 89左右。据此，可推测hclv 、猪瘟野毒株和c株之间的e2基因序列及氨基酸序列无明显差异。 | | 4. | Pathogenicity of 31 field strains of infections bursal disease viruses ( ibdv ) isolated during 1997 - 2001 in china was compared in spf chickens at different ages . the results indicated that the mortality induced by different strains varied very much . the mortality was also influenced by the age of chickens when infected
为了弄清我国各地流行的ibdv毒力程度，在3 ? 7周龄spf鸡进行人工感染的致病性试验，以此比较研究了1997 ? 2001年期间从我国不同地区分离到的31个ibdv野毒株。 | | 5. | In this paper , a field strain of infectious bronchitis virus was isolated from proventriculus tissue , morphological observation by electron - microscope and the biological characterizations of the virus were studied , pairs of specific primers are designed and synthesized in correspondence with them , according to the published sequences of infectious bronchitis virus three structural protein ( spike protein s membrane protein m nucleocapsid protein n ) genes , the cdna of si gene , s2 gene , m gene . n gene of ib v isolate lx4 were amplified by rt - pcr and full sequences were first reported
在此基础上，根据国内外已发表的ibv基因序列，分别设计特异性引物，应用不同引物进行反转录合成cdna ，分片段对ibv的主要结构基因进行pcr扩增，并分别将各个目的片段克隆到puc19载体上，在大肠杆菌dh5中实现目的基因的分子克隆，经蓝白斑筛选、限制性内切酶分析、 pcr鉴定，筛选出重组阳性质粒，并对各个目的基因片段进行序列测定，从而获得ibv主要结构基因全序列。 |
