The Studies on the Host Cell Apoptosis of Yunnan Sindbis Virus
Abstract: The one step growth curve of YN87448 strain virus in BHK21 cell showed that a lot of progeny viruses could be observed at 16 hr.after infection The tiler of virus reached the highest about 10一 0TCDS0 at 48 hour post infection.The titer of virus is not reduced by Co1.The apo ptosis was observed by the electron m icroscope and the DNA ladder was detected by agarose gel eletrophoresis. YN87448 strain virus can cause apo tosis in BHK21 cell and mice
