棘副睾吸虫、后双口吸虫（Posthodiplostomoides leonensis）、后双口吸虫（Posthodiplostomum sp.）和罗非鱼斜口吸虫（Clinostomum tilapiae）的囊蚴在适当的环境理化条件下的脱囊过程是由囊蚴主动启动的，而在后双口吸虫（Posthodiplostomum nanum）的脱囊过程中，囊蚴似乎不参与。温度、渗透压、pH和eH是影响这五种囊蚴的因素。新鲜牛胆汁被发现是不是一个绝对的必要性，为excystage的五个物种的研究，但它的存在下，在介质中增加了excystage的三个物种的速度。
Excystment of metacercariae ofParorchis acanthus, Posthodiplostomoides leonensis, Posthodiplostomum sp.andClinostomum tilapiaewas found to be an active process initiated by the metacercariae when the correct physico-chemical conditions exist in the environment; but in the excystment ofPosthodiplostomum nanumthe metacercaria seems not to take part in the process.Temperature, osmotic pressure, pH and eH are factors which influence all the five species studied. Fresh ox bile was found not to be an absolute necessity for the excystment of the five species studied but its presence in the medium increased the rate of excystment of three species.
