草履虫中孢囊对捕食者的防御功能的由来已久的假设最近被不同种类的单细胞捕食者的实验所证实。在本研究中，我们研究了三种后生动物的捕食者，Ceadellasp.（轮虫），Eucypris sp.（节肢动物），和狭口线虫（扁形动物）的防御功能。研究结果证实了棘孢囊对其中两种后生动物捕食者（Cephalodella sp.和Eucypris sp.）的防御功能，虽然它们对S似乎无效。- 是的我们还比较了四脲拟单胞菌的外泌体和两种纤毛虫的外泌体的防御效率。
The time-honored assumption about the defensive function of trichocysts in Paramecium against predators was recently verified experimentally against different species of unicellular predators. In the present study, we examined the defensive function of trichocysts against three metazoan predators, Cephalodella sp. (Rotifera), Eucypris sp. (Arthropoda), and Stenostomum sphagnetorum (Platyhelminthes). The results confirmed the defensive function of trichocysts against two of these metazoan predators (Cephalodella sp. and Eucypris sp.), while they seem ineffective against S. sphagnetorum. We also compared the defensive efficiency of the trichocysts of P. tetraurelia with that of toxin-containing extrusomes of two ciliates.
