草鱼出血病病毒对其它鱼的感染性研究

Study on Infecting Other Fishes with Grass Carp Hemorrhage Virus

用草鱼出血病病鱼分离出的草鱼出血病病毒(Grass carp hemorrhage virus,GCHV)感染其它常见鱼并用ELISA方法检查感染鱼组织提取液,结果表明:青鱼、鲢鱼、布氏鳌条对GCHV抗体呈阳性反应;鲤鱼、鳙鱼、鲫鱼、团头鲂、泥鳅则呈阴性反应。综合感染鱼发病症状及死亡特征,初步认为:青鱼对GCHV是易感的,GCHV能在鲢鱼、布氏蟹条体内增值,但毒力较低,鳙鱼、鲫鱼、团头鲂、鲤鱼、泥鳅能抗GCHV感染。

Eight common fishes were infected with grass carp hemorrhage virus (GCHV)that was from sick grass carp with hemorrhage symptom. ELISA detection showed that artificially infected black carp, silver carp and Hemiculter bleekeri blcckeri were positive, and then carp, variegated carp, triangular bream, loach and Megalobrama amblyoephala were negative against GCHV antibody.
