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). Thus, the intermediate host serves only as a site wherein the parasite spends a particular developmental stage of its life cycle (i.e. larval stage). Example: tapeworm using a pig as intermediate hosts.
What are the types of host?
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 difference between vector and intermediate host?
Because they play different roles in parasite life cycles, it seems appropriate that these different host types (vectors, which transmit a parasite or pathogen, and intermediate hosts, which are necessary for a parasite to complete its life cycle) should not necessarily be grouped under the same umbrella term.
What is meant by definitive host?
Definition of definitive host
: the host in which the sexual reproduction of a parasite takes place — compare intermediate host sense 1.
Which is example of definitive host?
A big examples of definitive hosts are humans, which can harbor viruses, bacteria, and worm-like parasites like the pinworm, whip-worm, and some tapeworms. Plasmodium; the malaria parasite requires both humans and the mosquito, but its definitive host is the mosquito.
What is the intermediate host of malaria?
The intermediate host of malarial parasites is a mosquito of the genus anopheles that can infect humans and other mammals. Malaria is caused by mainly the protozoan parasite Plasmodium.
What is the intermediate host of the trematodes?
The digenean (two-host) life cycle of a parasitic trematode typically consists of a vertebrate primary host, in which sexual reproduction of the parasite occurs, and an intermediate host, typically an aquatic snail, in which the parasite reproduces asexually.
What are the types of intermediate hosts?
Intermediate hosts are small wallabies and rat kangaroos, Macropus rufogriseus, Thylogale billardierii and Potorous tridactylus, the metacestodes occurring in the skeletal and cardiac muscle (Gregory et al., 1975).
Which of the following is the intermediate host of wuchereria?
Humans serve as the definitive host and mosquitos as the intermediate host. The adult parasites reside in the lymphatics of the human host.
What is host and type of host?
These are: Definitive host (DH). A definitive host is an organism that hosts the adult (sexual) form of the parasite. Intermediate host (IH). An intermediate host is an organism that hosts the asexual form of the parasite (only when there is an obligatory passage through the host).
