| Gregarine parasites alternate hosts, having the reproductive and vegetative phase in the intestines of xanthid crabs, and sporogony in oysters. |
| In Jodi's case, she was looking at some of the effects of host intestinal environment on gregarine metabolism and survival. |
| For at last they become an Acinetan or a gregarine, exactly like the parent-cell from which they arose as embryos. |
| The students established beetle populations with and without gregarine infection and then monitored the population over time. |
| Histological examination showed gregarine protozoan Nematopsis sp. |
| This mode of infection probably explains why heavy infections in this gregarine are rare, even in crowded cultures of roaches? |
