A parasite is a living plant or animal organism that survives in or on another species and benefits by absorbing nutrients from the host.
A parasite is a tiny plant or animal organism that lives on or with or inside a larger species and acquires food from the host. In some situations, the parasite can harm the host and in other situations it’s presence is completely harmless. There are three types of parasites namely ectoparasites, endoparasites and mesoparasites.
Ectoparasites include parasites that survive outside the host and induce itching and rashes in that area. Endoparasites include parasites that survive inside the body of the host. For example, blood streams, muscles, digestive system and so on. Mesoparasites include parasites that enter the host through an opening of the body and embeds themselves partially on the host.
In a broad sense, parasitic infections are caused by protozoa, helminths and arthropods. For instance, giardia is an intestinal infection caused by the giardia parasite.
