Parasites
A parasite is defined as 'an organism that
grows, feeds, and is sheltered on or in a different organism while contributing
nothing to the survival of its host. In humans, three types of intestinal
parasites may live in the small and large intestines: tapeworms, roundworms,
protozoa, and candida. Certain types remain in the intestines; others travel
outside the intestines to invade other organs. Some are so small they can only
be seen under a microscope; others can be many feet long. Most tapeworms and
roundworms develop in the human body and lay their eggs there. The eggs then
pass out of the body through feces or bowel movements, and can infest others.
