AIM
To compare the recovery of parasites in faecal samples using the Midi Parasep with ethyl acetate and Midi Parasep Solvent Free (SF) faecal parasite concentrators.
METHODS
23 preserved and 11 fresh faecal samples were microscopically examined for the presence of parasites using the Midi Parasep concentrator with ethyl acetate centrifuged for 1 and 3 min and the Midi Parasep SF concentrator.
RESULTS
The Midi Parasep SF faecal parasite system recovered significantly fewer ova and cysts and resulted in a notably larger deposit than the Midi Parasep concentrator with ethyl acetate.
CONCLUSIONS
Parasites present in small numbers that would be detected using the Midi Parasep concentrator with ethyl acetate could be missed using the SF faecal parasite system.
目的
比较使用 Midi Parasep 与乙酸乙酯和 Midi Parasep 无溶剂（SF）粪便寄生虫浓缩器在粪便样本中回收寄生虫的情况。
方法
使用 Midi Parasep 浓缩器，用乙酸乙酯离心 1 分钟和 3 分钟，以及 Midi Parasep SF 浓缩器，对 23 份保存的和 11 份新鲜的粪便样本进行显微镜检查，以确定寄生虫的存在。
结果
Midi Parasep SF 粪便寄生虫系统回收的卵囊和包囊明显较少，沉淀物明显大于用乙酸乙酯的 Midi Parasep 浓缩器。
结论
使用 Midi Parasep 与乙酸乙酯的浓缩器可以检测到数量较少的寄生虫，如果使用 SF 粪便寄生虫系统，可能会错过这些寄生虫。
