| 摘要: |
| 鸡胚中过高的母源抗体会干扰Lasota毒株的繁殖。本试验结果证明，当母源抗体＞26时种毒（EID50 108.5,HA 210）稀释1×103-5×103倍；母源抗体平均24左右时，种毒稀释5×103-1×104倍；母源抗体降至23左右时，种毒稀释倍数1×104-1×105为宜。按以上方法接种鸡胚，所收毒液效价最高。 |

| Abstract: |
| High maternal antibody in chick embryo influenced reproduction of Newcastle Disease Virus(Lasota strain).The result of experiment showed when the maternal antibody was over26（HI），The seed virus(EID50 108.5, HA 210)was diluted 1×103-5×103times, when the maternal antibody was 24，The seed virus was diluted5×103-1×104times, when the maternal antibody was 23, The seed virus was diluted 1×104-10×104times, According to this method to inoculate chick embryo ,The titer of virus in embryo water was the highest. |
