Classification of Parasites

Flashcards covering key concepts related to the classification of parasites, including definitions and examples of various types of parasites.

Parasite

An organism that has sustained contact with another organism to the detriment of the host organism.

Host

The animal that harbors a parasite, providing it with protection and nourishment.

Endoparasite

Parasites that live inside the host.

Ectoparasite

Parasites that are found attached to the skin of the host.

Helminthic Parasites

Multicellular organisms that are classified as flat worms, segmented ribbon-like worms, or cylindrical worms.

Protozoan Parasites

Unicellular organisms classified by their mode of locomotion.

Obligate Parasite

Parasites that cannot exist without a host (e.g., malaria).

Facultative Parasite

Parasites that can exist independently in the environment and can also parasitize a host when necessary.

Accidental Parasite

Parasites that enter a host accidentally and differ from their normal host.

Definitive Host

The host in which the parasite achieves sexual maturity, reaching the adult stage.

Intermediate Host

The host in which the immature or larval stage of the parasite is found.

Zoonosis

A disease of animals that can be transmitted to humans.

Vector

An animal that transmits parasites from one host to another.

Amoebiasis

A disease caused by Entamoeba histolytica, leading to amoebic dysentery.

Giardiasis

An infection caused by Giardia lamblia, which can lead to gastrointestinal symptoms.

Leishmaniasis

A disease caused by Leishmania donovani.

Malaria

An infectious disease caused by Plasmodium falciparum.

Helminthes

A major group of parasites including roundworms (Nematodes), flatworms (Trematodes), and segmented worms (Cestodes).

Nematodes

Roundworms that are cylindrical and unsegmented.

Cestodes

Tape-like segmented worms part of the helminthes.

Trematodes

Leaf-like unsegmented flatworms, also known as flukes.
