What are the effects of parasites on their hosts?

Parasites may influence their hosts in different ways. They may cause the death of the host due to a direct lethal effect or an indirect effect. Direct lethal effects may occur if killing is a part of the life cycle of the parasite or if hosts and parasites have not developed an equilibrium.

What is a parasite host in science?

Parasitism is a symbiotic relationship between species, where one organism, the parasite, lives on or inside another organism, the host, causing it some harm, and is adapted structurally to this way of life. Parasites of animals are highly specialised, and reproduce at a faster rate than their hosts.

Host: 1. The organism from which a parasite obtains its nutrition and/or shelter. 2. An organism or cell culture in which a virus can replicate itself.

Types of hosts

  • accidental host. a host that shelters an organism which does not usually parasitize that host.
  • incidental host (a.k.a. dead-end host) a host that shelters an organism but is unable to transmit the organism to a different host.
  • primary host (a.k.a. definitive/final host)
  • reservoir host.

    What is the types of host?

    Types of hosts Definitive or primary host – an organism in which the parasite reaches the adult stage and reproduces sexually, if possible. Secondary or intermediate host – an organism that harbors the sexually immature parasite and is required by the parasite to undergo development and complete its life cycle.
