Definition Definition Organism that lives in the body of another organism and obtains food at the expense of the host. A parasite can directly or indirect harm the host. There are two kinds of parasites: internal and external. An internal parasite lives inside another organism and is known as an endoparasite. An external parasite lives on the body surface of the host and is known as an ectoparasite. Protozoa and helminths are examples of major human parasites.

Expert Solution & Answer

Explanation of Solution

The humans serve both as an intermediate host (larvae in the muscle) and a definitive host (adult worm in the intestine) for Trichinella. Both larval and adult forms can parasitize the humans as definitive hosts but later on, they become intermediate, when the larvae get established in between the muscles.

After the first week, they start to release the larvae that penetrate the intestinal wall and move to the muscle tissues where they encyst. The same host sustains the adult worm temporarily but larvae for a longer period of time.

Conclusion

Thus, the humans serve both the intermediate as well as the definitive host for the genus Trichinella.
