Cricket paralysis virus, an insect picorna-like virus, caused a distinct c.p.e. in cultured Drosophila melanogaster cells, allowing the development of titration methods based on end-point dilution or plaque assay methods. The end-point dilution (TCD50) method is more sensitive and economical than plaque assays and is easily scored. The data indicate a minimum infectivity/particle ratio of about 1/2000.
蟋蟀麻痹病毒,一种昆虫类微小核糖核酸病毒,在培养的黑腹果蝇细胞中引起明显的细胞病变效应,从而使得基于终点稀释或空斑测定法的滴定方法得以发展。终点稀释(TCD50)法比空斑测定法更灵敏且经济,并且易于评分。数据表明最小感染性/粒子比率约为1/2000。
