A comparative enzymatic study is carried out on adults of three species of the genus Echinostoma (E. caproni, E. togoensis, E. sp.). Amongst 23 enzymes tested by starch gel electrophoresis, Pgm and Pgi are characterised by different zymogrammes in each species. Agarose and polyacrylamide isoelectrophoresis focusing define isoenzyme genetic structures: Pgm is coded by three loci, Pgi is coded by one locus. Pgm polymorphism allows us to extend this work to other experimental or natural stocks.
对棘口吸虫属的三个物种（卡氏棘口吸虫、多哥棘口吸虫、棘口吸虫未定种）的成虫进行了一项比较酶学研究。在用淀粉凝胶电泳测试的23种酶中，磷酸葡萄糖变位酶（Pgm）和磷酸葡萄糖异构酶（Pgi）在每个物种中具有不同的酶谱。琼脂糖和聚丙烯酰胺等电聚焦电泳确定了同工酶的遗传结构：Pgm由三个基因座编码，Pgi由一个基因座编码。Pgm多态性使我们能够将这项工作扩展到其他实验种群或自然种群。
