The term protozoa is used for a diverse and very big group of organisms with more than 65,000 known species of single celled creatures that display unique features for movement, feeding and behaviour. Most protozoans are harmless and free-living, but a few species are parasitic and cause major health concerns in humans.

Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.
