What do you mean by intermediate host give an example?

An intermediate host often acts as a vector of a parasite to reach its definitive host (where it will become mature).

Example: tapeworm using a pig as intermediate 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.
