摘要: 从暴发鸡传染性法氏囊病(IBD)死亡率63.51%的病死鸡中,分离出一株IBD病毒(IBDV)901株。经检测,901株是一株IBDV超强毒株,可使31日龄健康雏鸡71.4%死亡,10日龄SPF鸡胚和30日龄SPF雏鸡100%死亡。死亡鸡再现了自然暴发IBD的典型病变。

关键词: 鸡传染性法氏囊病, 超强毒, 感染

Abstract: A wild poison strain 901 was isolated from the bursal tissue of dead flow flock burst out by IBD, and its mortality rate was 63.51%.901 is extra-strong poison strain (IBDV).When artificially infected it to the 31-day-old health susceptible chicken flock,the death rate reached 71.4% and infected it to the 10-day-old SPE embryo and 30-day-old SPF chicken, the mortality rate was 100%.The typical pathological changes of IBD could be found in dead flow flock.
