该病毒在 meaning in Chinese
novell
Examples
- The sars virus also does not seem to be airborne ( float in the air for long periods ) , otherwise loads of people would have caught it by now
好像sars病毒也不会通过空气进行（远距离）传播（因为该病毒在空气中存活时间不长） ，否则现在感染的数目不会这么少。 - 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
理化学研究表明，该病毒为rna病毒，对氯仿、乙醚敏感；胰酶试验中，经37 、 1小时处理的病毒，仍然能够在猫源细胞fcwf细胞上生长，并且毒力基本保持不变；耐酸性试验中，病毒分别在ph5 . 0和ph3 . 0经37作用2小时，毒力仅下降一个滴度；耐热性试验中，该病毒在恒定温度50 ，设定不同时间，从5分钟到150分钟，毒力均有不同程度下降，其中， 50作用30分钟，病毒平均滴度下降2个单位； 50 ， 60分钟， cpe消失；恒定时间1小时，设定不同温度( 50 - 60 - 70 - 80 ) ，病毒在细胞上完全丧失增殖能力， cpe消失。生物学试验，利用实验室现有条件，选择不同的细胞系对该病毒进行培养，发现该病毒对猫源细胞fcwf最敏感； mdck细胞次之； f81细胞经多次传代，亦可出现cpe ；而vero细胞则不敏感。血凝试验表明，该病毒对猪、鸡、人及豚鼠的红细胞均无血凝性。
