| | 2. | bq per gram , a fatal dose of 4 sv can be caused by ingesting about 5 x 10 贝可的放射性活度,故此如果进食了大约5 x 10
| | 3. | the donkey - adapted strain of eiav ( dv116 ) , parental strain of eiav - dla , is a highly virulent isolate which was developed by sequential passaging a virulent eiav strain in donkeys in 1970s . the donkeys inoculated with fatal doses of eiav d strain can always be killed within in the first acute disease period . in this study , we constructed a full - length provirus dna clone of dv116 by pcr 本实验中将eiav驴强毒dv体外感染驴白细胞培养物,一定时间后收获病毒(本文中简称dv116 ) ,提取eiav前病毒dna ,以pcr法分别扩增并克隆了包含全长基因的三段前病毒dna片段,以双脱氧法测定了dv116病毒全基因序列共8236个核苷酸。
