为了研究远东地区并殖吸虫的生物学及流行病学,作者于1974～1977年,在黑龙江流域进行并殖吸虫的实验室研究和现场调查。从流行区动物体内的寄生虫囊包中取得卫氏并殖吸虫虫卵作为实验材料。虫卵经洗涤后,放在蒸溜水(或脱氯的自来水中)于室温或恒温箱内培育。虫卵孵出毛蚴的时间为15天(27～28℃恒温箱中)或30天(18～
In order to study the biology and epidemiology of Paragonimus in the Far East, the author conducted laboratory research and field investigation of Paragonimus in Heilongjiang River Basin from 1974 to 1977. Paragonimus westermani eggs were obtained from parasitic capsids of endemic area animals as experimental materials. The eggs are washed and placed in distilled water (or dechlorinated tap water) and incubated at room temperature or incubator. Egg hatching miracidia for 15 days (27 ~ 28 ℃ incubator) or 30 days (18 ~
