Abstract
Giardia muris cysts were separated from fecal contaminants in primary isolates by unit gravity velocity sedimentation. Crude isolates obtained by centrifugation over 1.0 M sucrose were overlaid onto a Percoll density gradient, 1.01 to 1.03 g/ml. G. muris cysts were well separated from faster-sedimenting fecal debris and slower-sedimenting Spironucleus muris and bacteria in 1.5 h.
摘要
通过单位重力速度沉降法，从初代分离物中的粪便污染物中分离出鼠贾第虫包囊。将通过在1.0 M蔗糖上离心获得的粗分离物覆盖在密度为1.01至1.03 g/ml的Percoll密度梯度上。在1.5小时内，鼠贾第虫包囊与沉降较快的粪便残渣以及沉降较慢的鼠螺旋体和细菌得到了很好的分离。
