| 中文摘要: |
| 对虾白斑综合征病毒是对虾养殖业危害最为严重的病毒, 每年给对虾养殖造成很大经济损失, 已成为对虾养殖业可持续发展的严重障碍。在过去的十几年中, 人们采取各种方法防止白斑综合征病毒的传播。中国明对虾(Fenneropenaeus chinensis )、凡纳滨对虾( Litopenae vannamei)、日本囊对虾(Marsup enaeus jap onicus)是我国主要的对虾养殖品种, 也是白斑综合征病毒的敏感宿主。按照煮沸- 乙醇沉淀法快速、简便提取市售30 只中国明对虾、28只凡纳滨对虾、29只日本囊对虾DNA, 然后用地高辛标记的核酸探针进行斑点杂交检测白斑综合征病毒,从而了解市场中养殖对虾携带白斑综合征病毒的情况。检测结果显示, 所有样品均未感染白斑综合征病毒, 说明目前白斑综合征病毒在一定程度上得到了有效控制。

| 英文摘要: |
| White spot syndrome virus (WSSV) was considered the most serious virus for shrimp aquaculture. This virus has brought great yearly economic losses in world shrimp farming and has become a major deterrent in the growth and sustainability of shrimp aquaculture . In the past more than 10 years , many techniques have been used to prevent this virus' transmission. Fenneropenaeus chinensis , Litopenaeus vannamei , Marsupenaeus japonicus are three kinds of popular cultured shrimp in China. They are also WSSV acute hosts. In this paper , DNA of 30 Fenneropenaeus chinensis , 28 Litopenaeus vannamei ,29 Marsupenaeus japonicus bought from seafood market were extracted rapidly by applying the method of boiling - ethanol precipitation , and then detected by digoxigenin - labeled mucleic probe dot blot hybridization for white spot syndrome virus carrying status. The results showed that all of the samples were WSSV negative , which indicated that WSSV was controlled effectively to some degree in China. |
