| 摘 要： | 参照鱼类病毒性出血性败血症病毒序列,根据PCR引物设计的原则,设计巢式PCR引物,采用巢式逆转录聚合酶链反应(RT-PCR)方法,对如何快速检测鱼类病毒性出血性败血症病的方法进行了较为系统的研究,并对RT-PCR的反应条件进行了优化.结果表明,巢式RT-PCR扩增获得279bp的特异性片断,阴性对照无扩增条带.巢式RT-PCR扩增出的特异性片段经测序分析,结果证实与报道的序列完全一致.该方法最低可检测出0.1pg的鱼类病毒性出血性败血症病毒RNA.初步建立了VHSV的巢式RT-PCR检测方法,该方法灵敏、特异,可为VHSV的检测提供一个快速、有效的手段. |

| Abstract: | Fish viral hemorrhagic septicemia virus (VHSV) is a rhabdovirus in fish causing serious fish mortality. With the results of genomes sequence analysis on VHSV, two pairs of primers were designed. Under optimized RT-PCR conditions, target regions of VHSV glycoprotein gene were amplified using VHS1-2 and VHS3-4 primers. Products of 279bp segment were shown after the nested RT-PCR reaction. Negative control showed no amplification. The RT-PCR product was proved identical to previously reported VHSV sequence. The detection limit of the nested RT-PCR assay is 0.1pg. Therefore, the nested RT-PCR assay, a sensitive, specific, and quick tool for VHSV detection is established. |
