MICP-FINALS-1

The study of large parasites

An organism that harbors a parasitic, mutualistic, or commensalist guest, the guest typically being provided with nourishment and shelter

An organism that depends on the host for survival. An organism that obtains nourishment and shelter from another organism

A living organism that carries a disease-causing organism to new hosts (e.g., mosquitoes, fleas, live, sandflies, and ticks)

One species (symbiont/parasite) benefits to the detriment of the other

A form of relationship between two, unlike organisms.

S a biological interaction between two species wherein both species benefit from each other

Only one specie benefits from the other, without harming nor benefiting the other

Invasion of the body by ectoparasites

Those that live inside of the host’s body (e.g., helminths, worms)

Those that live outside of the host’s body (e.g., fleas, lice).

Invasion of the body by endoparasites.

Facultative can't live independently.

Obligate parasite must exist as a parasite inside a host

Occur on an unusual host.

Simply visit the host during feeding time

Larva develops in a host while the adult is free-living.

Remain in a host from early life to maturity

Becomes fixed in an unusual organ different from that which is ordinarily parasitized.

Hosts that harbor the adult stage of the parasite

Vertebrate hosts that harbor the parasite and may act as an additional source of infection in man

One in which the parasite cannot complete its development or the appropriate phase of its development

Where the asexual stage of the life cycle of the parasite occurs.

Final host must eat this host for the adult parasite to develop.

Carrier host, it harbors the parasite, serves as a source of infection of other susceptible hosts

Adult stage of parasite

Host larval stage, no development takes place

False host, the parasite can’t reach its maturity

Larval stage, amateur asexual stage, asexual stage of the life cycle of the parasite occurs
