Leucochloridium paradoxum, the green-banded broodsac, is a parasitic flatworm (or helminth).Its intermediate hosts are land snails, usually of the genus Succinea.The pulsating, green broodsacs fill the eye stalks of the snail, thereby attracting predation by birds, the primary host.
Mesocercaria: They are involved in an encysted stage either on vegetation or in a host tissue on the second intermediate host. They have a hard shell and are also involved in the trophic transmission. This is where the parasite is able to infect the definitive host because it consumes the second intermediate host that has metacercariae on/in it.
Thus the host goes into water and the parasite's lifecycle completes. [13] Many of the genes the parasites use for manipulating their host have been acquired through horizontal gene transfer from the host genome. [14] There are a few cases of accidental parasitism in vertebrate hosts, including dogs, [15] cats, [16] and humans.
Dracunculus is a genus of spirurid nematode parasites in the family Dracunculidae. The worms can reach a metre in length. If one simply pulls off the protruding head of the worm, the worm will break and leak high levels of foreign antigen which can lead to anaphylactic shock and fast death of the host. Hence it is important to remove the worm ...
Many mycoparasites are fungi, though not all fungicolous fungi are parasites (some are commensals or saprobes. [2]) Biotrophic mycoparasites acquire nutrients from living host cells. Necrotrophic mycoparasites rely on dead host cells, which they might first kill with toxins or enzymes ( saprophytic growth).
Dracunculiasis, also called Guinea-worm disease, is a parasitic infection by the Guinea worm, Dracunculus medinensis.A person becomes infected by drinking water contaminated with Guinea-worm larvae that reside inside copepods (a type of small crustacean).

Strongyloides stercoralis is a human pathogenic parasitic roundworm causing the disease strongyloidiasis.Its common name in the US is threadworm.In the UK and Australia, however, the term threadworm can also refer to nematodes of the genus Enterobius, otherwise known as pinworms.
