Enoplea (enopleans) is a class, which with the classes Secernentea [1] and Chromadorea make up the phylum Nematoda in current taxonomy. [2] [3] [4] The Enoplea are considered to be a more ancestral group than the Chromadorea, and researchers have referred to its members as the "ancestrally diverged nematodes", compared to the "more recently diverged nematodes" of Chromadorea.
The nematodes (/ ˈ n ɛ m ə t oʊ d z / NEM-ə-tohdz or NEEM-; Ancient Greek: Νηματώδη; Latin: Nematoda), roundworms or eelworms constitute the phylum Nematoda. Species in the phylum inhabit a broad range of environments. Most species are free-living, feeding on microorganisms, but many are parasitic.
Enoplida Filipjev, 1929 – nematodes of marine and brackish water habitat, carnivorous or feed on diatoms and other algaes; Triplonchida Cobb, 1920 – terrestrial nematodes, including some plant parasites; Trefusiida Lorenzen, 1981
Subclass Rhabditia is mostly composed of parasitic nematodes (particularly in the Strongylida), though there are some free-living species as well (particularly in the Rhabditida). Phasmids (posterior sensory structures) are well-developed, while amphids (anterior sensory structures) are poorly developed or absent in this group.
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.
Life cycle of Trichuris trichiura inside and outside the human body. The female T. trichiura produces 2,000–10,000 single-celled eggs per day. [3] Eggs are deposited from human feces to soil where, after two to three weeks, they become embryonated and enter the "infective" stage.
The Anisakis simplex is a parasitic roundworm classified under the phylum Nematoda. [2] [5] It possesses the typical characteristics of its phylum, including an unsegmented, cylindrical body that occasionally fills up with fluids and allows it to swim freely. [5]
