摘要
对已经分离的鸡新城疫病毒分离株部分生物学特性进行了测定 .该新城疫病毒分离株对 1日龄雏鸡脑内接种致病指数 (ICPI)为 1.5 1,鸡胚最小致死量 (MLD)为 10 -8,平均死亡时间 (MDT)为 46 .2h ,鸡胚半数感染量 (EID50 )为 10 -10 .1,并与已知标准株进行了比较 .按规定的标准判定 ,该分离株为毒力较强的鸡新城疫强毒株 .
Biological characteristics in part of avian Newcastle disease virus isolate strain were determinated.The ICPI in 1-day-old chickens was 1.51,MLD in chicken embryos was 10 -8 ,MDT was 46.2 h,EID 50 in chicken embryos was 10 -10.1 .According to the provided criterion,the results indicated that the avian NDV isolated strain be a virulent strain.
