1Relating to a group of microscopic, wormlike protozoans that are internal parasites of insects, annelids, and other invertebrates.
- Aseptate gregarine fauna have been reported from various parts of the world including India.
- These were determined to be the trophozoites of a gregarine parasite of the insect, and the present paper records the observations which have been made on this species.
- The students established beetle populations with and without gregarine infection and then monitored the population over time.
A gregarine protozoan.
- Class Gregarina (or subclass Gregarinidia), phylum Sporozoa, kingdom Protista.
- Ciliates are alveolate protozoa that evolved unusually large cell sizes entirely differently from gregarines, with radically novel consequences for their genomes.
- The cytoplasm of the gregarines was always irregular, dense, and occasionally presenting a dark stoch area.
- Like the gregarines, however, the life cycle is primarily haploid, with diploidy only occurring before meiosis.
Mid 19th century: from modern Latin Gregarina, from Latin gregarius (see gregarious).
