【摘要】：为比较不同保存方式对鸡减蛋综合征灭活抗原的影响,采用禽腺病毒京911株(CVCC AV70)经尿囊腔接种易感鸭胚,收获感染鸭胚液,经β-丙内酯灭活后,对该抗原的保存条件及其稳定性等方面进行优化。冻干抗原与未冻干抗原在相同温度下,冻干抗原HA效价下降较慢。冻干抗原在2~8℃和-15℃以下保存,HA效价没有明显差异。因此,生产的鸡减蛋综合征灭活抗原要在冻干后保存在2~8℃最佳。保存条件的优化不仅可以减少经济损失,而且还有助于更好的控制禽腺病毒疫情的暴发。
[Abstract]:In order to compare the effect of different preservation methods on the inactivated antigen of egg drop syndrome (EDS), the susceptible duck embryo was inoculated with avian adenovirus Jing911 strain (CVCC AV70) through allantoic cavity, and the infected duck embryo was harvested and inactivated by 尾 -propionolactone. The preservation conditions and stability of the antigen were optimized. The HA titers of freeze-dried antigens decreased slowly at the same temperature as that of non-freeze-dried antigens. There was no significant difference in HA titer between 2 鈩，
