The non-parasitic nature of pathogens. Introduction: The two dangerous organisms that cause diseases in the host are pathogens and parasites . The major difference between both of them is that pathogen is a disease-causing agent in the host, while the parasite is a type of pathogen that causes disease in a host by living on or inside it in order to obtain nourishment. In return, parasite provides no benefits to the host; it either causes disease in the host or kills it.

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.
