雏鸭病毒性肝炎病毒山东株的分离鉴定

Isolataion and identification of Shandong duck hepatitis virus

自山东地区疑似雏鸭病毒性肝炎的发病或病死肉雏鸭的肝脏中分离到3株病毒,经病毒分离、血清中和试验、单抗Dot-ELISA鉴定、氯仿敏感试验以及动物回归试验,确诊该地区雏鸭所患为Ⅰ型鸭病毒性肝炎。高免卵黄抗体的被动保护试验结果表明,高免卵黄抗体可有效控制Ⅰ型雏鸭病毒性肝炎的发生。

Three strains of virus were isolated from the dead ducks in some duck farms of shandong, which were suspected to be duck virus hepatitis(DHV) .They were determined to be DHV - I serotype by duck embryo neutralization test,Dot - ELISA and dulklings protecting test. A good control effect was obtained by inoculating this yolk antibody to the ducklings.
