What is an example of a obligate parasite?

Biology definition: An obligate parasite is a parasite that entirely depends upon a host for its nourishment, reproduction, habitat, and survival. Examples: hookworm, Plasmodium, head louse, cuckoo paper wasp, Rafflesia. Synonym: obligatory parasite; holoparasite.

What is the difference between obligate and temporary parasite?

An obligate parasite is strictly dependent on a host organism to complete its life cycle and survival. A facultative parasite does not strictly depend on a host to complete its life cycle. Even with the absence of the host, facultative parasites are able to complete their life cycles.

What is an example of a facultative parasite?

Facultative parasites live primarily as saprophytes, but can infect living plants when conditions are favorable. Examples are the organisms that cause brown patch (Rhizoctonia solani) and Pythium blight (Pythium aphanidermatum) diseases.

What is Digenetic parasite give an example?

Digenetic parasites need more than one host to complete their life cycle. Plasmodium vivax, the protozoa that carries malaria, is digenetic. In order to complete its life cycle, it must be a parasite of both people and mosquitos.

What is obligate parasite?

An obligate parasite or holoparasite is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. If an obligate parasite cannot obtain a host it will fail to reproduce.

What is aberrant parasite?

Aberrant parasite or wandering parasite- They infect a host where they cannot live or develop further e.g. Toxocara in humans.

Is a virus an obligate parasite?

Viruses are small obligate intracellular parasites, which by definition contain either a RNA or DNA genome surrounded by a protective, virus-coded protein coat.

Is Armillaria facultative parasite?

The fungus prefers dead tissue over living tissue and once killed, the fungus moves through the dead wood more rapidly than through the living wood (Raabe, personnel communication). Armillaria is a facultative parasite.

What do you mean by Digenetic?

Definition of digenetic : of or relating to a subclass (Digenea) of trematode worms in which sexual reproduction as an internal parasite of a vertebrate alternates with asexual reproduction in a mollusk.

What is facultative and obligate parasite?

An obligate parasite or holoparasite is a parasitic organism that cannot complete its life-cycle without exploiting a suitable host. This is opposed to a facultative parasite, which can act as a parasite but does not rely on its host to continue its life-cycle.

What does obligate mean in microbiology?

Able to exist or survive only in a particular environment or by assuming a particular role: an obligate parasite; an obligate anaerobe.

What is an obligate stem parasite?

An obligate parasite cannot complete its life cycle without a host. A stem parasite attaches to the host stem.
