  1. The comparison of meq gene sequences of different pathotypes of marek ' s disease virus meq genes of different pathotypes of marek ' s disease virus ( mdv ) were amplified, in the whole opening reading frame ( orf ) by polymerase chain reaction ( pcr ) technique, sequenced and compared with the published sequence of ga strain ( representing vmdv ). cvi988 / rispens and 814, commercial vaccine strains popularly used worldwide and in china respectively ; 648a, representing very virulent plus ( vv + mdv ) and 6 field isolates, originated from guangxi commercial chickens with visceral lymphomas and vaccine breaks, representing high pathogenic ( hpmdv ) and two of them ( g2 and n ) were proved to be vvmdv, were used

    本研究通過三個方面進行了研究,取得了如下主要實驗結果: 1mdv不同致病型( pathotypes )毒株meq基因序列的比較研究應用pcr技術擴增了不同致病型mdvs ,即國際通用型疫苗毒cv1988 rispens株和中國特有的疫苗毒814株、特超強毒648a株( vv + mdv )以及6個廣西分離到的野毒株共9個毒株的meq基因,進行核苷酸序列的測定並與標準強毒ga株( vmdv )進行核苷酸和氨基酸序列的比較。
  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

    分別以傳染性法氏囊病病毒zj2000株(野毒株)和jd1株(弱毒株)基因組dsrna為模板,採用long - accuratert - pcr ( la - pcr )一步法擴增並克隆了兩株病毒的基因組a節段全長cdna 。
