A technic is described whereby poliomyelitis virus may be sedimented by centrifugation for four hours at 18,000 r.p.m. Virus has been recovered quantitatively in the sediment from a 20 per cent., but not a 1 per cent., saline suspension. The addition of 10 per cent. normal serum results in quantitative recovery from a 1 per cent. suspension. Virus has been recovered by intracerebral inoculation from two of four human stools tested by the method described.
描述了一种技术,通过该技术,脊髓灰质炎病毒可以在 18,000 r.p.m. 的转速下离心沉淀四个小时。从 20%盐水悬浮液中可以定量回收病毒,但从 1%盐水悬浮液中不能回收。添加 10%正常血清可从 1%悬浮液中定量回收病毒。通过描述的方法,从 4 个人粪便中检测到的 2 个粪便中,通过脑内接种法回收了病毒。
