摘要: |
将引进的ReoS1133株强毒 在SPF鸡胚上传1代,对E2代种毒进行了病毒含量和对雏鸡的毒力测定,结果表明,E2代种毒病毒含量≥105.9EID50/0.2ml。对3~7周龄雏鸡的半数感染量≥ 104.16~4.18/0.1ml,ReoS1133株强毒毒力符合要求,可以作为强毒攻毒株。 |

Abstract: |
Avian Reovirus (Strain S1133 ) were passaged on the SPF chichen embryo. Virulence to the SPF chichens was identified and contents were taken for the passage 2. The results showed that passage 2 (Strain S1133 ) contained more than 105.9EID50/0.2ml and contained more than 104.16~4.18 CID50/0.1ml. It complied with the requirements as a challenge strain. |
