Parasitology Courses: Every living thing on Earth has at least one parasite associated with it that is dependent on that organism called as host for its nutrition. Parasites can be found both inside and outside of the body of their host and have a profound impact on that it. Thus, parasitology is the field of biology that studies these parasites and their interaction with their host. It is a dynamic field that studies the constantly changing relationship between the parasite and its host.
