摘要
用鸡源新城疫(ND)强毒株F48E9和鸵鸟源新城疫强毒株O-XJ99-12,对不同免疫状态下2~4月龄鸵鸟进行动物试验。动物发病后经剖检、组织切片、病毒分离等方法证实:鸵鸟源和鸡源新域疫病毒(NDV)毒株,经静脉和黏膜感染非免疫鸵鸟,均可引起特征性的鸵鸟ND症状和病变,对鸡胚致病力强的NDV毒株,对非免疫鸵鸟的致病力也强;鸵鸟ND的免疫临界点,HI抗体效价最低为5log2。
Selecting different immune state 2-4 month-old ostriches,infected NDV virulent strain F48E9 and O-XJ99-12 which isolated from chichen and ostrich respectively.Using anatomy,histological section and viral isolation etc analysed pathogenetic bird,the result indicated NDV isolated from chicken and ostrich both caused classic ND symptom and pathological changes,after infecting nonimmune ostrich by intravenous injection and membrana mucosa,the virus which appears more virulence to chicken,so as do to ostrich.The...
