Which organism causes trichinellosis?

Trichinellosis is caused by a tissue-dwelling nematode called Trichinella. The illness comes from eating undercooked pork or wild game that contains Trichinella cysts; after ingestion, the larvae are released in the gut, mature into adults, and then migrate to skeletal muscle where they encyst, leading to symptoms like fever and muscle pain. This distinguishes it from other parasites: Giardia causes giardiasis (a protozoan infection often from contaminated water), Ascaris lumbricoides causes ascariasis (a large intestinal roundworm infection), and Taenia species cause taeniasis (tapeworm infections). So the organism responsible for trichinellosis is Trichinella.
