Trichinella nativa is a nematode worm, one of the species of the Trichinella genus.
It is found in arctic and subarctic regions.
It is highly pathogenic and has a high resistance to freezing. It is encapsulated. It infects a wide variety of mammals and birds. The life cycle and pathogenesis are similar to Trichinella spiralis. Trichinella nativa can cause trichinellosis.
This nematode infects the muscles of mammals such as the Arctic fox and the polar bear. In order to complete its life cycle, it is necessary for the flesh of its host to be eaten by some other mammal. In the Arctic, the corpses of animals that die may get frozen and later be consumed by scavengers. This worm remains viable even after being frozen at −18 °C (0 °F) for four years.
