| Tadpoles in ponds with snails pick up trematode larvae, called cercariae. |
| Effects of certain environmental factors on emergence of cercariae of Austrobilharzia variglandis. |
| The larvae inside the snail host produce several thousands of cercariae. |
| The different geotactic behaviour of the two species of cercariae brings them into the ecological range of their different second intermediate hosts. |
| Total RNA was isolated separately from miracidia, sporocysts, cercariae, schistosomulum, and male and female adult worms. |
| Serum cytokines of the 20Krad-irradiated Schistosoma mansoni cercariae vaccinated, primary and superinfected Cercopethicus aethiops aethiops. |
