摘要
在研究中华绒螯蟹病害的过程中 ,分离到两株呼肠孤病毒 (分别命名为EsRV816和EsRV90 5 )。EsRV816从江苏某养殖场分离 ,EsRV90 5从武汉某养殖场分离。EsRV816和EsRV90 5的病毒粒子为球状对称结构 ,大小分别为 6 5nm和 5 5nm。病毒粒子基因组分别为 10和 12个节段的双链RNA。根据它们的宿主范围、基因组节段数及电泳型 。
Two different reoviruses were isolated during investigation on pathogens of diseased crab Eriocheir sinensis (designated as Es RV816 and Es RV905). Es RV816 was isolated from crabs collected from Jiangsu province. Es RV905 was purchased from a local farm in Wuhan, Hubei province. The spherical viral particles of Es RV816 and Es RV905 are about 65 and 55 nm in diameter. The two viral particles contain two different genomes of 10 and 12 RNA segments, respectively. Based on their hosts, number of segments and electrophoresis type of the genomes ,they may represent two new genera of the \%reoviridae\%.
