In trpsin tolerance assay. this virus could resist to 1 % trpsis at 37 in an hour. in acid tolerance assay, this virus was resistant to ph3. 0 and ph5. 0 at 37 in 2 hours, and the average infection litre of the virus decreased little. in heat assay, at 50, the virus was processed from 5 minutes to 150 minutes and at each condition the viral virulence reduced to some certain degree. among these conditions, when at 50 in 30 minutes. the average infection litre of this virus decreased over 2 tilre. and when al 50 in an hour, cpe of ihis virus disappeared. when time was set for an hour. but with processed in different temperature as 50 60 70, 80, the virus losl the multiplication capacity complelely. in biological assay, we selected different cell lines to cultivate this virus by laking advantage of possesional cells at that time in our laboratory. then we found that fcwf cell line was the most sensitive to dxmv and mdck was the second. with f81 cell line, after passaged for 12 times continuously with low concentration of fcs. the virus could produce cpe. however, with vero cell line. the virus could not procuce any cpe after many passages. the hemagglutination and lumadsorption reaction test proved that this virus had no any reaction to erythrocyte of pig, fowl and cavy. by neutrolizaion assay, dxmv could be identified as a kind of ccv
