  1. The results indicate that the nucleotide sequences and deduced amino acid sequences of all the guangxi isolates in the signal peptides were highly homologous, but lowly homologous with other reference strains. the amino acid composes and arrangement of all guangxi isolates at the cleavage site has the typical pattern of ndv virulent strains, and is identical with the facts in the field cases. all the guangxi isolates are classified into genotype vii of apmv - 1, the same genotype dominated in china and other areas in recent years

    結果發現，廣西分離株之間在信號肚的核旮酸和氨基酸同源性很高，而與其它參考株差異較大；廣西分離株在裂解位點的氨基酸組成和排列均符合強毒株的特徵，並與毒株在臨床上的致病情況相符；根據apmvlf基因第47位第420位核苦酸序列所繪制的系譜樹吵ylogenetictree ）來看，廠西雞和鵝分離株都歸屬于基因型vll 。
  2. This strain ' s virulence was judged by mean death time of chick embryos ( mdt ), intracerebral pathogenicity index in day - old chicks ( icpi ) and intravenous pathogenicity index in 6 - week - old chickens ( ivpi ) and it was found to be the virulent strain. at last, it was tested by the recurrent infection and found that it was the newcastle disease virus ( ndv ), and it was named hbg - 1 strain. in order to find the difference of the cleavage site of this strain with f48e9 and ? 30 strain, a part of the cleavage site of fusion protein gene fragment was amplified by rt - pcr using a primer and sequenced. the sequence analysis showed this strain had low homology with f4ge9 and cso. a phylogenetic tree based on the published sequences of ndv reference strains was constructed and showed the isolated strain hbg - 1 belonged to the genotype w ndv, a novel genotype ndv

    為了進一步探尋分離株與標準株的異同，又採用rt - pcr方法，擴增獲得分離株f _ o裂解位點附近的基因片段，經測序后與國際上已發表的新城疫病毒的核酸序列進行比較，結果表明其與標準株和疫苗株之間的同源性較低，僅為82 86之間。經系統發育進化樹分析后，判定該分離株為新城疫病毒（ ndv ）基因型。運用計算機軟體對其裂解位點處的氨基酸序列進行預測和分析，結果表明該分離株為新城疫病毒強毒株並具有基因型的典型結構特徵。
  3. Although dramatic variation occurs frequently in genome of type a influenza virus, the np gene is comparatively conservative representing virus type specificity

    雖然a型流感病毒變異頻繁，但其核蛋白（ np ）是其保守性蛋白，具有種群和型的特異性。
  4. The hemaglutinin ( ha ) of aiv plays the key role in determing the pathogenicity, cell receptor binding property and host range of the virus. the homology of the ha sequences reported and registered in genbank of different strains of h _ ( 5 ). h _ ( 9 ) subtype was respectively analyzed and compared with each other. the conservative domin of ha seqence of h _ ( 5 ), h _ ( 9 ) subtype was selected for pcr amplification. two sets of specific primers were designed

    本研究根據genbank中查出的禽流感病毒h _ 5亞型，禽流感病毒h _ 9亞型的ha片段基因組序列，利用dnasis軟體分別對aiv的h _ 5 、 h _ 9亞型ha基因區域進行同源性比較，設計篩選出兩對聯合pcr反應的特異性引物，其中一對是h _ 9亞型通用引物，擴增出ha片段695bp ，另一對引物為h _ 5亞型的通用引物，擴增出的ha區域部分目的片段約為448bp 。
  5. The gene cloning and sequence analysis of senv - d and senv - h isolated from china according to the published nucleotide sequences of sen viruses, specific primers were designed and synthesized. from the serum of two chinese patients with non - a - e hepatitis, one senv - d isolate named senv - d - bj1 spanning the complete coding region was amplified by semi - nested pcr, another isolate named senv - d - bj2 spanning the partial coding region ( including orf1 and orf2 ) was amplified too. from one blood donor serum, two senv - h isolates named senv - h12 - 1 and senv - h 12 - 2 spanning the complete coding region were amplified by nested pcr respectively

    Sen病毒d和h亞型中國分離株的克隆及序列分析我們在前期工作的基礎上，結合已發表的文章及基因序列，針對senv - d和senv - h基因組設計特異性引物，利用套式pcr技術從兩例non - a - e肝炎患者血清中分段克隆得到了一個senv - d亞型分離株（ senv - d - bj1 ）的全部編碼區基因序列，還得到了一個senv - d亞型分離株（ senv - d - bj2 ）的大部分編碼區基因序列（包括orf1和orf2 ） ；從一例健康人血清中分段克隆得到了兩個senv - h亞型分離株（ senv - h12 - 1和senv - h12 - 2 ）的全部編碼區基因序列。
