The 2 main types of intestinal parasites are helminths and protozoa. Helminths are generally visible to the naked eye in their adult stages, whereas protozoa are single-celled organisms.
Can intestinal parasites be seen?
Additionally, some intestinal parasites are large enough to be seen with the naked eye and may appear as white thread-like creatures in stools. While some parasites don't cause noticeable symptoms, some grow, reproduce or invade healthy functioning systems, making their hosts sick, resulting in parasitic infection.
