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.
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.
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]
Type 1 diabetes (T1D) is an autoimmune disease in which the immune system destroys the body's pancreatic beta cells. [2] In an experiment with mice, infection with parasitic worms or helminth-products generally inhibited the spontaneous development of T1D, according to Anne Cook in the journal Immunology . [ 2 ]
The CCN is a sedentary endoparasitic nematode, establishing feeding sites in the roots of host plants near the vascular tissue. Like other cyst nematodes, CCN feeds from a specialized feeding site known as a syncytium. This feeding site is formed by the deterioration of cell walls of adjoining plant cells in response to elicitors delivered ...
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 ...
Radopholus similis is a species of nematode known commonly as the burrowing nematode. [1] It is a parasite of plants, and it is a pest of many agricultural crops. It is an especially important pest of bananas , and it can be found on coconut , avocado , coffee , sugarcane , other grasses , and ornamentals .
Heterodera sacchari, [1] [2] the sugarcane cyst nematode, mitotic parthenogenic sedentary endoparasitic nematode. This plant-parasitic nematode infects the roots of sugarcane , and the female nematode eventually becomes a thick-walled cyst filled with eggs.
