Infectious Salmon anaemia virus (ISAV) has become a threat to the salmon industry worldwide and has caused considerable economic loss. In the present study, 9 suspect cases of ISAV infection were identified from iced Atlantic salmons imported from Norway in 2014 through Shenzhen port (Shenzhen, China) using methods recommended by the World Organization for Animal Health. However, the results of virus isolation were negative., Based on the sequence analysis of ISAV segment 6, the 9 ISAV isolates belonged to the HPRO type, had high homology (98.3%~100.0%) and closest relationship with Norway strains. We identified the 9 positive HPRO ISAVs from 491 iced Atlantic salmons (1. 8%). Therefore, we should strengthen the quarantine of iced Atlantic salmons from Norway in case of HPRO ISAV into China.
传染性鲑鱼贫血病毒(ISAV)已成为全球鲑鱼养殖业的一大威胁,并造成了相当大的经济损失。在本研究中,2014年通过深圳口岸(中国深圳)从挪威进口的冰鲜大西洋鲑中,采用世界动物卫生组织推荐的方法,鉴定出9例疑似ISAV感染病例。然而,病毒分离结果为阴性。基于ISAV第6节段的序列分析,9株ISAV分离株属于HPRO型,与挪威毒株具有高度同源性(98.3%~100.0%)且亲缘关系最近。我们从491条冰鲜大西洋鲑中鉴定出9株阳性HPRO ISAV(1.8%)。因此,我们应加强对从挪威进口的冰鲜大西洋鲑的检疫,以防HPRO ISAV传入中国。
