泰国输华斑节对虾传染性皮下和造血器官坏死病毒的检测与分析

摘要

为研究进口斑节对虾传染性皮下和造血器官坏死病毒（Infectious Hypodermal and Hematopoietic Necrosis Virus， IHHNV）的风险，本文采用了世界动物卫生组织（OIE）2015版手册中推荐的PCR方法，对2015年从泰国输华的329批次斑节对虾进行了IHHNV检测分析。结果发现，其阳性率高达36.8%，且主要是感染1型和2型，以及风险不明的未知型。因此，来自泰国的斑节对虾具有较高的IHHNV传入风险，应加强针对IHHNV的进口监测，减少其对我国对虾养殖的影响。%In order to study the risks of Infectious Hypodermal and Hematopoietic Necrosis Virus(IHHNV) of importedPenaeus monodon,PCR methods recommended by OIE manual(2015)were used to test IHHNV on 329 batches ofPenaeus monodon imported from Thailand. The results showed that positive rate was 36.8%,and major genotypes were genotype 1,2 and unknown type with unclear risk. Therefore,the IHHNV risk ofP. monodon imported from Thailand is high. Suggestions of reinforcing the surveillance of 1HHNV to control this disease and limit the negative effect on shrimp aquaculture of China were put forward.
