  1. 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。
  2. Response to poultry farmers request for early resumption of day - old chick imports

  3. When inoculated into 11 - day - old meat - type chick embryos, alv - j imc10200 and sdc2000 strain induced typical ml occurring after 42 weeks post - hatching

    將分離毒株回歸感染肉雞， 21周齡時特異性引物pcr抽查檢測，抽查感染雞全部為陽性； 42周齡后出現典型ml病例。
