1Relating to a group of microscopic, wormlike protozoans that are internal parasites of insects, annelids, and other invertebrates.
- ‘The students established beetle populations with and without gregarine infection and then monitored the population over time.’
- ‘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.’
- ‘We have used a number of different systems, but most often these have involved the helminth communities of frogs and small fish, insects and their gregarine parasites, and more recently, nematomorphs.’
- ‘In Jodi's case, she was looking at some of the effects of host intestinal environment on gregarine metabolism and survival.’
- 1.1(of movement) slow and gliding, as seen in gregarine protozoans.
A gregarine protozoan.
- ‘Figure 1 shows the prevalence of these gregarines in adult damselflies during the summer and early fall of this year.’
- ‘Like the gregarines, however, the life cycle is primarily haploid, with diploidy only occurring before meiosis.’
- ‘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.’
- ‘This mode of infection probably explains why heavy infections in this gregarine are rare, even in crowded cultures of roaches?’
- ‘The gregarine is compared with other species in the genus Leidyana reported from different hosts to establish its distinctiveness.’
