| The different geotactic behaviour of the two species of cercariae brings them into the ecological range of their different second intermediate hosts. |
| Only the tadpoles that were exposed to cercariae developed deformities. |
| It was not only possible to generate mother sporocysts from miracidia in vitro, but also to obtain adult worms from cercariae through in vitro cultivation. |
| Through a complex process of asexual replication, each miracidium larva gives rise to dozens, or even hundreds, of cercariae. |
| Studies on cercariae from Physa gyrina Say, with descriptions of two new species. |
| Tadpoles in ponds with snails pick up trematode larvae, called cercariae. |
