Trichinella is the genus of parasitic roundworms of the phylum Nematoda that cause trichinosis. Members of this genus are often called trichinella or trichina worms. A characteristic of Nematoda is the one-way digestive tract, with a pseudocoelom.
The genus was first recognised in a larval form in 1835. The L1 larvae live in a modified skeletal muscle cell. From Wikipedia
