Ophidascaris robertsi is a nematode (also known as roundworm) [3] usually parasitic in the carpet python (Morelia spilota). [4] It is found in Australia and Papua New Guinea. Pythons serve as the typical hosts for Ophidascaris robertsi , which has an indirect life cycle.
Trichodoridae (stubby-root nematodes, trichodorids) is a family of terrestrial root feeding nematodes, being one of two that constitute suborder Triplonchida. [ 3 ] [ 4 ] They are economically important plant parasites and virus vectors.
Aphelenchoides besseyi is a plant pathogenic nematode. It is sometimes referred to as rice white tip, spring dwarf, strawberry bud, flying strawberry nematode or strawberry crimp disease nematode. [1] [2] [3] This foliar nematode is found in Africa, North, Central, and South America, Asia, Eastern Europe, and Pacific islands. [4] [5] [6]
Gongylonema pulchrum was first named and presented with its own species by Molin in 1857. The first reported case was in 1850 by Dr. Joseph Leidy, when he identified a worm "obtained from the mouth of a child" from the Philadelphia Academy (however, an earlier case may have been treated in patient Elizabeth Livingstone in the seventeenth century [2]).
Mansonella ozzardi is a filarial (arthropod-borne) nematode (roundworm). This filarial nematode is one of two that causes serous cavity filariasis in humans. The other filarial nematode that causes it in humans is Mansonella perstans. M. ozzardi is an endoparasite that inhabits the serous cavity of the abdomen in the human host. It lives within ...
The nematode has a cuticle with 4–6 layers. The lips are offset with 4–5 annules, which are divided into tile-like structures. The nematodes body is slightly curved when relaxed. [4] [5] Females have two ovaries which overlap the spermatheca. The vulva is found near the center of the body and the rectum near the tip of the tail.
About 90% of nematodes reside in the top 15 cm (6") of soil. Nematodes do not decompose organic matter, but, instead, are parasitic and free-living organisms that feed on living material. Nematodes can effectively regulate bacterial population and community composition—they may eat up to 5,000 bacteria per minute.
Meloidogyne incognita (root-knot nematode, RKN), also known as the southern root-nematode or cotton root-knot nematode is a plant-parasitic roundworm in the family Heteroderidae. This nematode is one of the four most common species worldwide and has numerous hosts. It typically incites large, usually irregular galls on roots as a result of ...
