In evolutionary ecology, a parasitoid is an organism that lives in close association with its host at the host’s expense, eventually resulting in the death of the host. … Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible.
How do you kill worms in humans?
