摘  要:
马立克氏病病毒 (MDV) GA强毒株的 Bam H - L 片段 DNA全长为 2 892 bp,G+C比率为 5 5 .91%。用内切酶将其亚克隆为 6个片段 :Bam H - Pst 、Pst - Pst 、Pst - Cla 、Cla - Sm a 、Sm a - Sma 和 Sm a - Bam H 。用地高辛标记 L 片段 DNA或者分别标记其 6个亚片段核酸 ,通过斑点杂交试验都可将 MDV血清 1型毒株与 2型和 3型的毒株区分开来 ,应用 PCR方法可获得相同结果。但 PCR方法更敏感、更快捷。结果表明 ,MDV GA强毒株的Bam H - L片段 DNA对 MDV血清 1型毒株是特异的

摘  要:
The complete nucleotide sequence of BamHⅠ-L fragment of Marek′s Disease Virus(MDV) GA strain is 2 893 bp,with a base composition of 55.91% G+C.Its six subfragments were obtained from the pBR322-L recombinant plasmid and subclonal plasmid(pUC118,SK+)(BamHⅠ-PstⅠ,PstⅠ-PstⅠ,PstⅠ-ClaⅠ,ClaⅠ-SmaⅠ,SmaⅠ-SmaⅠ,SmaⅠ-BamHⅠ),then labelled with the Digoxigenin as gene probe.These probes were hybridized with MDV serotype Ⅰ(MDV-1),serotype Ⅱ(MDV-2) and serotype Ⅲ(MDV-3).The results indicate that the L-fragment and its six subfragments are unique to MDV-1 viruses and has not homologue with MDV-2 and MDV-3.Same result can be obtained by PCR.But PCR is much more sensitive and fast.The BamHⅠ-L fragment DNA of MDV GA strain is proved to be specific to MDV-1.
