Parasitic infections

A parasite is an organism that lives in the body of another organism and obtains food at the expense of the host. There are two kinds of parasites they are internal and external. An internal parasite lives inside another organism and is known as endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite.
