Trichinella/Trich·i·nel·la/ (trik″ĭ-nel´ah) a genus of nematode parasites, including T. spira´lis, the etiologic agent of trichinosis, found in the muscles of rats, pigs, and humans.
A nematode genus in the aphasmid group that causes trichinosis in humans and carnivores.
[Mod. L. fr. trichina + dim. suffix -ella]
A genus of nematode worms belonging to the order Trichurida and the family Trichinellidae. They are parasitic in humans, hogs, rats, and many other mammals.
The species of Trichinella that commonly infests humans, causing trichinosis. Infection occurs when raw or improperly cooked meat, particularly pork and wild game, containing cysts is eaten. Larvae excyst in the duodenum and invade the mucosa of the small intestine, becoming adults in 5 to 7 days. After fertilization, each female deposits 1000 to 2000 larvae, which enter the blood or lymph vessels and circulate to various parts of the body where they encyst, esp. in striated muscle.See: illustrationillustration
a genus of nematode parasites in the family Trichinellidae.
Trichinella spiralis spiralis (T1), Trichinella pseudospiralis (T4), Trichinella spiralis domestica (Trichinella spiralis), Trichinella britovi (T3), Trichinella nativa (T2) and Trichinella nelsoni (T7)
adult worms of the species listed above, together with their internationally recognized code numbers, are found in the intestines and the encapsulated, first stage larvae in the striated muscle of various animals. Three other species of uncertain taxonomy, T5, T6, T8, are also encountered. T. spiralis is a common cause of infection in humans as a result of ingestion of poorly cooked pork.
