In this article we are going to discuss about what is pathogen, what is parasite and the Difference Between pathogen and Parasite. Generally, pathogens and parasites are kind of microorganisms that can harm to the host organisms, but there are some important differences between pathogen and parasite.

Pathogens are the kind of microorganisms that cause diseases, such as bacteria, viruses, fungi, and protozoa. These spread fungal infections in the host’s body and weaken the host’s immune system.

On the other hand, parasites are organisms that depend on the host organism for life cycle, such as insects and lice. They take nutrition and protection from their host organisms and sometimes they even destroy or kill the host’s organisms.

Both pathogens and parasites can be harmful to the host, but parasites have a more complex life cycle and can remain associated with the host for a longer period.

What is the Difference Between Pathogen and Parasite?

A pathogen is an organism or agent that causes disease in its host.A parasite is an organism that lives on or in a host organism and depends on it for survival, often causing harm or disease.
Pathogens include viruses, bacteria, fungi, and other infectious agents.Parasites can be protozoa, helminths (worms), or arthropods like ticks and lice.
Pathogens typically do not require a host to complete its life cycle.Parasites will have to depend on their host to complete their life cycle.
They spread through various means such as air, water, or direct contact with infected individuals.Parasites typically live within or on the host, acquiring nutrients at the host’s expense.
Examples include influenza virus, Salmonella bacteria, and malaria parasites.Examples include malaria parasites, tapeworms, and fleas.
