The cytomorphologic method previously reported for titration of adenoviruses has been employed for estimating the infectious titer of simian virus 40 (SV 40). Infected cells forming intranuclear inclusions were determined. The method examined possesses a number of advantages over virus titration by plaque assay and cytopathic effect. The virus titer estimated by the method of inclusion counting and expressed as IFU/ml (Inclusion Forming Units/ml) corresponds to that estimated by plaque count and expressed as PFU/ml.
先前报道的用于腺病毒滴定的细胞形态学方法已被用于估计猿猴病毒40(SV 40)的感染滴度。确定形成核内包涵体的感染细胞。与通过空斑测定法和细胞病变效应进行病毒滴定相比,所研究的方法具有许多优点。通过包涵体计数法估计并以IFU/ml(包涵体形成单位/毫升)表示的病毒滴度与通过空斑计数法估计并以PFU/ml表示的病毒滴度相对应。
