摘　　要：本研究采用对流免疫电泳方法(CIEP)检测辽宁水貂养殖场疑似水貂阿留申病毒(aleutian mink disease virus,ADV)水貂血清抗体,采集抗体阳性水貂的肝脏、脾脏、肾脏和肠系膜淋巴结组织,电镜观察存在细小病毒样颗粒。组织液研磨无菌处理后,接种CRFK细胞,盲传6代,取病毒细胞分离液用PCR方法检测,呈ADV阳性。将病毒分离液纯化后接种健康水貂,隔离观察,接种后3d即出现食欲减退,贫血,被毛无光泽,后期出现拒食、狂饮、死亡,个别水貂出现神经症状,表现抽搐、痉挛、步态蹒跚、共济失调,证明分离获得的病毒为ADV强毒株,命名为ADV-LN株。Mink suspected infection aleutian mink disease virus（ADV）from mink breeding areas in Liaoning province were tested with CIEP method.The mink with antibody to ADV were selected and culled.Liver,spleen,kidney and mesenteric lymph node samples were taken for pathological examination and the viruses were observed under electron microscope.The grinded tissue fluid filter was added penicillin and treptomycin and inoculated into CRFK cells and passaged by 6times for virus isolation.And cells cultures were identified as ADV by PCR.Then they were inoculated into healthy mink.Three days later,the mink showed clinical signs,which including the loss of appetite,anemia,hair dull,antifeedant and binge drinking.Some minks showed neurological symptoms,manifested symptoms of convulsions,cramps,staggering gait,ataxia,or hind limb paralysis and died.The virus strains isolated and identified were named as the ADV-LN.
