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.
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.
Ascaris is a nematode genus of parasitic worms known as the "small intestinal roundworms". [1] One species, Ascaris lumbricoides, affects humans and causes the disease ascariasis. Another species, Ascaris suum, typically infects pigs.
The most common causes of intestinal parasites are through consumption of contaminated water, infected soil, inadequate sanitation and hygiene, and improper hygiene. [3] Specifically, lack of access to facilities for safe disposal of human waste can result in intestinal parasites and disease.
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 ...
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 .
Generally, human nematodes are less likely to develop resistance due to longer reproducing times, less frequent treatment, and more targeted treatment. Nonetheless, the global community must be careful to maintain the effectiveness of current anthelmintic as no new anthelmintic drugs are in the late-stage development.
