Abstract
A strain of virus,which was suspected to be duck hepatitis virus(DHV),was isolated from the diseased and dead ducks in the duck farm in Anhui province in China.The virus strain was isolated by means of saline suspension and blastula inoculation.Animal test indicated that the death rate was 70%.Through observation of clinical performance and the results of dissection and passive conservancy blood serum test,the pathologic materials were diagnosed as DHV.Duck blastula neutralized test proved that the serotype of the virus was type Ⅰ.
