What is the difference between an intermediate host and a definitive host?

The definitive host is the one which harbors the adult parasite and where the parasite reproduces sexually.

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.
