Why are some people more susceptible to parasites?

British researchers have identified a protein that exists in some people's gut mucus that seems to be toxic to parasitic worms. Those with the protein are able to ward off infection, while those who lack the protein are more easily infected with the parasites, researchers said.

Where do parasites hide in the body?

For example, (i) parasites can hide away from the immune system by invading immune-privileged tissue such as the central nervous system or the eye (Bhopale 2003). Also some parasitoids place their eggs inside tissue such as the fat body that is not well patrolled by the host's immune system.

What is the most harmless parasite?

Nonpathogenic intestinal protozoa are single-celled parasites commonly found in the intestinal tract but never associated with illness. They do not harm the body, even in people with weak immune systems.
