摘要
本文利用形态分类学方法、生活史培养、染色体和同工酶分析，系统地描述两种片形吸虫的可比特征。提出在种类鉴别上较直观、不易混淆的分类特征。肝片吸虫成虫的形态与巨片吸虫除大小不同外，更明显的不同是成虫的前部和后端吸虫体长宽比，腹吸盘直径与口吸盘直径比等方面。生活史培养中各期虫体的形态与发育时间也表现出很大的不同。染色体比较分析说明肝片吸虫与巨片吸虫为同源三倍体和同源二倍体。同工酶分析显示两种吸虫的酯酶同工酶相同，过氧化物酶在种类鉴别上有意义。
In this paper two spices fascioles were described systematically,using morphology,life cycle culture,chromosome and isoensyme analysis. The characteristics easy to confirm were established.In the two specis of adult,the front part and end,the ratio of length to width and diameter of abdomen sucker to mouth sucker were different,besides the shape in size. There are many deferences between the two spices in life cycle culture and the time of development stage. The chromosome analysis showed that Fasciola hepatica and F. gigentica are autopolyploid triplont and diplont.Isoenzym analysis also proved the differences between the two spices.
