Ascaridia galli is a parasitic roundworm belonging to the phylum Nematoda. Nematodes of the genus Ascaridia are essentially intestinal parasites of birds. [1] A. galli is the most prevalent and pathogenic species, especially in domestic fowl, Gallus domesticus. It causes ascaridiasis, a disease of poultry due to heavy worm infection ...
Ascaris lumbricoides. Linnaeus, 1758. Ascaris lumbricoides is a large parasitic roundworm of the genus Ascaris. It is the most common parasitic worm in humans.

Internal anatomy of a male C. elegans nematode. Nematodes are very small, slender worms: typically about 5 to 100 μm thick, and 0.1 to 2.5 mm long. [47] The smallest nematodes are microscopic, while free-living species can reach as much as 5 cm (2 in), and some parasitic species are larger still, reaching over 1 m (3 ft) in length.
Ascaris lumbricoides Linn., 1758. Ascaris suum (Goeze, 1782) Ascaris is a nematode genus of parasitic worms known as the "small intestinal roundworms", which is a type of parasitic worm. [1] One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Another species, Ascaris suum, typically infects pigs.
The roundworm, of a previously unknown species, survived 40 meters (131.2 feet) below the surface in the Siberian permafrost in a dormant state known as cryptobiosis, according to Teymuras ...
The pinworm (species Enterobius vermicularis), also known as threadworm (in the United Kingdom, Australia and New Zealand) or seatworm, is a parasitic worm. It is a nematode (roundworm) and a common intestinal parasite or helminth, especially in humans. [7] The medical condition associated with pinworm infestation is known as pinworm infection ...
The Anisakidae are also called the " marine mammal ascarids". The larvae of these worms cause anisakiasis when ingested by humans in raw or insufficiently cooked fish, but do not reproduce in humans. The Ascarididae include the giant intestinal roundworms (Ascaris spp.). The Cosmocercidae include taxa that parasitize certain amphibians.
