| 摘 要： | 2001年3月以来,江苏部分地区番鸭场流行了一种新的烈性传染病,该病的主要特征为肝脏出现大量灰白色坏死灶(故暂定为坏死性肝炎),经初步研究,该病病原为一种新病毒,该病毒粒子呈球形,无囊膜,有可见的双层衣壳结构,外壳直径75nm左右,内核直径50nm左右,呈二十面体对称排列。核酸类型为双股RNA。该病毒能致死番鸭胚,只引起雏番鸭发病死亡。

| Abstract: | A new infectious disease which attacked Muscovy Ducklings in some parts of Jiangsu Province in China has been reported since March 2001.The disease showed characteristic necrotic locus with lots of gray-white filled with liver.The Pathogen was isolated and identified as one member of avian reovirus.Under TEM,the virus show spherical particles with isometric symmetry,no envelope,double deck capsids,with outercapsid of 75nm,inner one of 50nm in diameter. Viral nucleic acid was identified as double strand RNA.Virus pathogen only infect sensitive Muscovy Duckling with morbidity of 30%-90%, mortality of 10%-60%. |
