利用鳗鲡疱疹病毒(HVA) DNA聚合酶基因引物对患病双色鳗鲡和美洲鳗鲡进行PCR检测(PCR检测结果仅有双色鳗鲡),获得约394 bp的目的条带,测序表明扩增出的条带为AHV的DNA聚合酶基因片段,与 GeneBank 公布的 HQ992949、 GU233800、 FJ940765等6个鳗鲡疱疹病毒基因同源性为100%,与G U 205167、A F363783鳗鲡疱疹病毒基因同源性为99%。将患病双色鳗鲡、美洲鳗鲡肝脏和肾脏组织的除菌滤液,接种EPC细胞,细胞7 d出现CPE ,双色鳗鲡株传代至15代,美洲鳗鲡株传代至5代。
利用鰻鱺皰疹病毒(HVA) DNA聚閤酶基因引物對患病雙色鰻鱺和美洲鰻鱺進行PCR檢測(PCR檢測結果僅有雙色鰻鱺),穫得約394 bp的目的條帶,測序錶明擴增齣的條帶為AHV的DNA聚閤酶基因片段,與 GeneBank 公佈的 HQ992949、 GU233800、 FJ940765等6箇鰻鱺皰疹病毒基因同源性為100%,與G U 205167、A F363783鰻鱺皰疹病毒基因同源性為99%。將患病雙色鰻鱺、美洲鰻鱺肝髒和腎髒組織的除菌濾液,接種EPC細胞,細胞7 d齣現CPE ,雙色鰻鱺株傳代至15代,美洲鰻鱺株傳代至5代。

394 bp fragment was amplified and cloned from genomic DNA of the diseased A. Rostrata and A. bicolor bicolor. The nucleotide homology was 100% with DNA polymerase of 6 eels herpesvirus (HQ992949 ,GU233800 , FJ940765 ,EU349272 ,EU349271 ,AF333066) and 99% of 2 eels herpesvirus (GU205167 ,AF363783).The suspension of gill ,liver and kidney from diseased A. bicolor bicolor and diseased A. Rostrata which filtered through a filter membrane to get rid of bacteria was used to infected EPC cells , CPE appeared after 7 d. Now we have cultivated 14 generations from A. bicolor bicolor and 5 generations from A. Rostrata.
