TAN Wei-Guo, LI De-Qing and ZHOU Li-Gong. Propagation of EHFV in the Wish Cell Line[J]. Virologica Sinica, 1991, 6(2).
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.
