流行性出血热病毒在人革膜传代细胞内的生长繁殖

Propagation of EHFV in the Wish Cell Line

本文应用人羊膜传代细胞(Wish细胞)对流行性出血热病毒(EHFV)的敏感性进行了试验,用EHFV武株及76118、A9、R22、R4、陈株等5个代表株接种Wish细胞。结果Wish细胞感染EHFV后第1代第8～10天即可查见明显的特异性荧光,荧光光强度随代数和时间而增加,TCID50为10~4～/10~5ml。并用荧光阻断试验和双份血清证实在Wish细胞内繁殖的病毒为EHFV。此结果为EHF病原学研究提供了新的敏感细胞株。

In our experimental studies, 6 strains of EHFV were inoculated into the Wish cell cultures. We found that EHFV could propagate in this cell line and after several passages, viral titers can reach to 10^(4-5) TCID50/ml. After incubation no cell cytopathic effect could be observed in the Wish cell cultures. The result showed that the Wish cell is a new sensitive cell line for isolation of EHFV.
