Preliminary Studies on Two Strains of Reovirus from Crab Eriocheir sinensis
Abstract: Two different reoviruses were isolated during investigation on pathogens of diseased crab E— riocheir sinensis(designated as Es RV816 and Es RV905). RV816 was isolated from crabs collected from Jiangsu province.Es RV905 was purchased from a local farm in W uhan, Hubei province.The spherical viral particles of Es RV8 1 6 and Es RV905 are about 65 and 55 nm in diameter.The tWO viral particles contain two different genom es of 10 and 12 RNA segm ents, respectively. Based on their hosts,number of segments and electrophoresis type of the genomes,they may represent tWO new gen— era of the reoviridae.
