Rotations of plants with nematode-resistant species or varieties is one means of managing parasitic nematode infestations. For example, planting Tagetes marigolds as a cover crop just prior to planting a nematode-susceptible plant, has been shown to suppress nematodes. [ 67 ]
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)
There may be as many as 300,000 species of parasites affecting vertebrates, [9] and as many as 300 affecting humans alone. [10] Helminths of importance in the sanitation field are the human parasites, and are classified as Nemathelminthes (nematodes) and Platyhelminthes, depending on whether they possess a round or flattened body, respectively. [8]
This is an example of a trophic cascade in which consumers at the top of the food web (nematodes) exert an influence on the abundance of resources (plants) at the bottom. The idea that plants can benefit from the application of their herbivore's enemies is the principle behind biological control .
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 .
Brachylaimiasis is a parasitic infection caused by the intestinal trematode genus, Brachylaima, which infects various animals and one species known to infect humans. [10] The life cycle of Brachylaima involves a two (or more) intermediate terrestrial gastropod host being infected through the ingestion of eggs excreted by an infected definitive ...
A. lumbricoides is the largest intestinal roundworm and is the most common helminth infection of humans worldwide. Infestation can cause morbidity by compromising nutritional status, [ 3 ] affecting cognitive processes, [ 4 ] inducing tissue reactions such as granuloma to larval stages, and by causing intestinal obstruction , which can be fatal.
