About Parasite

Definition: It is an organism that can be lives in or on another organism (called the host) and obtains nutrients and resources from the host while potentially causing harm or diseases. Parasites can be unicellular (such as protozoa) or multicellular (such as helminths).

Characteristics: Parasites have adapted to their specific hosts and often have complex life cycles. They rely on the host for food, shelter, and reproduction. When they reside on the host’s surface, they are categorized as ectoparasites, and when they live within the host’s body, they are classified as endoparasites.

Functions: The primary function of a parasite is to extract resources from the host for its own survival and reproduction. Depending on the type of parasite, its abundance, and the host’s immune function reaction, parasites can induce a range of consequences on the host, ranging from a little discomfort to serious sickness.

Difference Between Pathogen and Parasite: Pathogens and parasites are two terms that describe microorganisms that can be harmful to the health of any living being. Here is the major difference between a pathogen and a parasite is that the term pathogen explains the effect of a microorganism upon another living being which is often harmful, whereas it is the term parasite describes the mode of living of a microorganism which may or may not be harmful.
