Scientific definitions for parasite


An organism that lives on or in a different kind of organism (the host) from which it gets some or all of its nourishment. Parasites are harmful to their hosts, although the damage they do ranges widely from minor inconvenience to debilitating or fatal disease.♦ A parasite that lives or feeds on the outer surface of the host's body, such as a louse, tick, or leech, is called an ectoparasite. Ectoparasites do not usually cause disease themselves although they are frequently a vector of disease, as in the case of ticks, which can transmit the organisms that cause such diseases as Rocky Mountain spotted fever and Lyme disease.♦ A parasite that lives inside the body of its host is called an endoparasite. Endoparasites include organisms such as tapeworms, hookworms, and trypanosomes that live within the host's organs or tissues, as well as organisms such as sporozoans that invade the host's cells. See more at host.

Parasite's Perfect Montage

Look up a word, learn it forever.

The adjective parasitic is mainly a scientific term for talking about an organism that lives on a host, taking what it needs to stay alive while often injuring the host.

By their nature, ticks, leeches, and lice are all parasitic; they live off their hosts. You can also use the word parasitic more metaphorically, to describe a person who takes without giving anything in return. A thirty year-old man who lives with his mother, eating her food and not paying rent, could be described as parasitic, since he survives by sponging off another person. Parasitic comes from the Greek word parasitos, "eating at another's table."

Dictionary parasites

Look up a word, learn it forever.

A creature that lives off another organism is a parasite. The parasite might not hurt the host, but it doesn't do anything to help it, either.

If you call someone a parasite, you are really hurling an insult! The Ancient Greeks used the word parasitos to describe someone who ate at your table but never invited you back. Some telling synonyms include leech," toady, sponge, and hanger-on." Nice, huh? Some crafty birds, such as the cowbird or cuckoo, are called social parasites, laying their eggs in other birds' nests and expecting those mamas to raise their young for them. Unfortunately, there are some people like that, too.
