Parasite aircraft
A parasite aircraft is a smaller aircraft carried and launched in flight by a larger mothership, a concept dating from 1931 and revived with air-recovered drones.
Parasite Egg Count
A parasite egg count is a laboratory measurement of parasite eggs per gram of feces, estimating helminth infection intensity in humans and animals and guiding public-health deworming programs.
Parasite Eve (video game)
Parasite Eve (パラサイト・イヴ), Squaresoft's 1998 PlayStation 'cinematic RPG' and survival-horror hybrid based on Hideaki Sena's novel; Aya Brea fights mitochondria entity EVE in New York; sold ~2M, spawned two sequels, dormant since 2010.

Parasite infection
Parasite infection (R-HSA-9664407) is a Reactome pathway describing Leishmania infection of human cells, from promastigote phagocytosis to amastigote formation in the parasitophorous vacuole, linked to cutaneous leishmaniasis.
Parasite Load
Parasite load (parasitic load, parasite burden) is the measure of the number of parasites present in a host organism, quantified by prevalence, intensity, and abundance; measured by necropsy, egg counts, microscopy, and qPCR, and central to host resistance versus tolerance.
Parasite single
Parasite single (パラサイトシングル) is a Japanese pejorative for unmarried adults living off their parents' household, coined by sociologist Masahiro Yamada in 1997 and popularized by his 1999 book.
Parasitellus
Parasitellus (bumblebee mites) is a genus of 11 Parasitidae mite species, formerly in Parasitus, obligate associates of Bombus nests in the Holarctic; deutonymphs disperse phoretically on queens, females feed on pollen, other stages prey on nest arthropods.
Parasites & Vectors
Parasites & Vectors (Parasit Vectors), ISSN 1756-3305, is an open-access, peer-reviewed BioMed Central/Springer Nature journal on parasites, vectors, and vector-borne diseases, founded 2008 by Chris Arme, IF 3.7 (2025).
Parasitic capacitance
Parasitic capacitance, also known as stray capacitance, is the unintended capacitance that exists between nearby conductors, causing crosstalk, op amp instability, and MOSFET false turn-on in fast circuits.
Parasitic crustaceans
Parasitic crustaceans are crustaceans, including copepods, isopods, and barnacles, that live at the expense of hosts such as fish; sea lice alone cost salmon farming about £700 million yearly.
Parasitic plant
Parasitic plants, also called hemiparasites and holoparasites, are flowering plants that steal water and nutrients from hosts via a haustorium; about 4,750 species, 12 independent origins, including Striga, Orobanche, Cuscuta, and Rafflesia.
Parasitic Sensitivity Tests
Parasitic sensitivity tests (MeSH D021261) measure the effectiveness of drugs against parasites, chiefly in vitro and ex vivo malaria IC50 and ring-stage survival assays supporting antimalarial resistance surveillance.
Parasitic twin
Parasitic twin (heteropagus, fetus in fetu, acardiac twin): a malformed conjoined twin dependent on a dominant twin's circulation, affecting under 1 in 1 million births, treated by surgery on the host.
Parasitic worm
Parasitic worm (helminth): large multicellular parasite of humans and animals, including flatworms, thorny-headed worms, and roundworms; adults cannot multiply in humans; soil-transmitted types are among the most common human parasites.
Parasitidae
Parasitidae, also historically equated with Gamasidae, is a family of predatory soil mites in Mesostigmata, superfamily Parasitoidea, with subfamilies Parasitinae and Pergamasinae, phoretic deutonymphs on insects, and unstable generic taxonomy.
Parasitism
Parasitism, a +/− symbiotic interaction in which a parasite benefits at a host's expense, is distinct from predation and parasitoidism, drives host coevolution and speciation, and is rising under global change.
Parasitoid
Parasitoid: insect whose larva develops on or in a single host and kills it, adults free-living; mostly wasps and flies, used in biological control, distinct from parasites and predators.
Parasitoid wasp
Parasitoid wasps, hymenopteran insects whose larvae kill their insect or arthropod hosts, are classified as idiobionts or koinobionts and ecto- or endoparasitoids; they manipulate hosts with venom, polydnaviruses, and teratocytes, and are leading biological control agents.
Parasitology
Parasitology, the study of parasites, their hosts, and parasite-host interactions, spans protozoa, helminths, and ectoparasites; established as a discipline in the late 19th century, it now combines microscopy, molecular diagnostics, and One Health control.
Paraskevopoulos (lunar crater)
Paraskevopoulos is a 98.87-km lunar farside impact crater at 50.09°N, 150.34°W, IAU-approved in 1970 and named for John Stefanos Paraskevopoulos, the Greek astronomer who directed Boyden Observatory (1923–1951).
Parasocial interaction
Parasocial interaction (PSI), also called parasocial relationship, is a one-sided bond with media figures, coined by Horton and Wohl in 1956; distinguished from reciprocal relationships by lack of mutuality, studied across influencers, celebrities, and AI agents.
Parasolid
Parasolid is a geometric modeling kernel owned by Siemens Digital Industries Software that computes exact 3D solid geometry for CAD products including NX, Solid Edge, SOLIDWORKS, and Onshape.
Parasomnia
Parasomnia: abnormal behaviors or experiences during sleep, sleep onset, or waking, including sleepwalking, night terrors, sleep paralysis, and REM sleep behavior disorder; classified as NREM, REM, or other parasomnias.
