Although many other parasitic thread worms cause diseases in living organisms (sterilizing or otherwise debilitating their host), entomopathogenic nematodes are specific in only infecting insects. Entomopathogenic nematodes (EPNs) live parasitically inside the infected insect host, and so they are termed as endoparasitic.
Gnathostoma spinigerum is a parasitic nematode that causes gnathostomiasis in humans, also known as its clinical manifestations are creeping eruption, larva migrans, Yangtze edema, Choko-Fuschu Tua chid and wandering swelling. [citation needed] Gnathostomiasis in animals can be serious, and even fatal.
This root-knot nematode is sedentary endoparasitic nematode. Second-stage juveniles (J2) penetrate host roots where they establish a specialized feeding site (giant cells) in the stele. As J2 develop, they cause root swellings and become swollen females. Females rupture root cortex and sometime protrude with the egg masses from the root surface.
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 body is long, cylindrical, and fusiform (pointed at both the ends). The body wall is composed of cuticle, epidermis and musculature. There is a pseudocoelom. Respiration is by simple diffusion. The nervous system consists of a nerve ring and many longitudinal nerve cords. Reproduction is exclusively sexual, and males are usually shorter ...
These can be categorized into three groups; cestodes, nematodes and trematodes. Examples include: Acanthocephala; Ascariasis (roundworms) Cestoda (tapeworms) including: Taenia saginata (human beef tapeworm), Taenia solium (human pork tapeworm), Diphyllobothrium latum (fish tapeworm) and Echinococcosis (hydatid tapeworm)
In terms of feeding strategy, Nacobbus is classified as a false root-knot nematode because it is both migratory endoparasitic and sedentary endoparasitic. [4] It is the only known nematode to do so; all others employ either one strategy or the other. In Nacobbus, each strategy is employed at different stages in the life cycle. [5]
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 ( enterobiasis ) [ 8 ] (a type of helminthiasis ) or less precisely as oxyuriasis in reference to the family Oxyuridae .
