    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) Clonorchis sinensis (the Chinese liver fluke) Dracunculus medinensis (Guinea worm) Enterobius ...

  3. Parasitism - Wikipedia

    en.wikipedia.org/wiki/Parasitism

    Parasitism is a major aspect of evolutionary ecology; for example, almost all free-living animals are host to at least one species of parasite. Vertebrates, the best-studied group, are hosts to between 75,000 and 300,000 species of helminths and an uncounted number of parasitic microorganisms.

  4. Host (biology) - Wikipedia

    en.wikipedia.org/wiki/Host_(biology)

    If one of the partners in an association is much larger than the other, it is generally known as the host. [1] In parasitism, the parasite benefits at the host's expense. [2] In commensalism, the two live together without harming each other, [3] while in mutualism, both parties benefit. [4] Most parasites are only parasitic for part of their ...

  5. Parasitology - Wikipedia

    en.wikipedia.org/wiki/Parasitology

    Parasites can provide information about host population ecology. In fisheries biology, for example, parasite communities can be used to distinguish distinct populations of the same fish species co-inhabiting a region. Additionally, parasites possess a variety of specialized traits and life-history strategies that enable them to colonize hosts.

  6. Ectosymbiosis - Wikipedia

    en.wikipedia.org/wiki/Ectosymbiosis

    European mistletoe is an example of an ectosymbiotic parasite that lives on top of trees and removes nutrients and water.. Ectosymbiosis is a form of symbiotic behavior in which an organism lives on the body surface of another organism (the host), including internal surfaces such as the lining of the digestive tube and the ducts of glands.

  7. Microsporidia - Wikipedia

    en.wikipedia.org/wiki/Microsporidia

    In that case, the microsporidian species is a hyperparasite, i.e. a parasite of a parasite. As an example, more than eighteen species are known which parasitize digeneans (parasitic flatworms). These digeneans are themselves parasites in various vertebrates and molluscs. Eight of these species belong to the genus Nosema. [25]

  8. Behavior-altering parasite - Wikipedia

    en.wikipedia.org/wiki/Behavior-altering_parasite

    By way of example, a parasite that reproduces in an intermediate host may require, as part of their life cycle, that the intermediate host be eaten by a predator at a higher trophic level, and some parasites are capable of altering the behavior of the intermediate host to make such predation more likely; [1] [2] a mechanism that has been called ...

  9. Disease ecology - Wikipedia

    en.wikipedia.org/wiki/Disease_ecology

    Parasites are able to limit population growth and reproduction of species which may lead to a shift in the balance of an ecosystem. [11] Other ways parasites impact systems are through nutrient cycles. Parasites are able to create imbalances of the elements in a system through the relationship they have with a host and the host's diet. [12]
