[ Method] The pneu- monia and purulent disease viruses were isolated from the abnormal and purulent lung tissues of musk deer. Then the isolated viruses were inocula- ted into the Vero cells. After culturing, the virus solution was collected and used to determine TCID50 and genoma types. The sensitivity to fat sol- vent, resistance to hydrochloric acid and trypsin as well as tolerance to heat of the musk deer pneumonia and purulent disease viruses were detec- ted, respectively. [ Result] The obvious cytopathic effects （CPE） were found in Veto cells infected by the isolated viruses. The virus was 2-1.43 TCID50/ml and its genome was RNA. The virus was not sensitive to chloroform, 1% trypsin and heats, and it had a certain tolerance to 0.1 mol/L hy- drochloric acid. [ Conclusion] The study on the physicochemical properties of musk deer pneumonia and purulent disease viruses lays a foundation for prevention and control of the musk deer pneumonia and purulent diseases.展开更多
