Trichinella spiralis is a viviparous [1] nematode parasite, occurring in rodents, pigs, bears, hyenas and humans, and is responsible for the disease trichinosis. It is sometimes referred to as the "pork worm" due to it being typically encountered in undercooked pork products.
Trichinosis is mainly spread when undercooked meat containing Trichinella cysts is eaten. [1] Wild meat is more likely to contain the parasite. [7] [8] In North America this is most often bear, but infection can also occur from pork, boar, and dog meat. [9] Several species of Trichinella can cause disease, with T. spiralis being the most common ...
Trichinella is the genus of parasitic roundworms of the phylum Nematoda that cause trichinosis (also known as trichinellosis). Members of this genus are often called trichinella or trichina worms . A characteristic of Nematoda is the one-way digestive tract, with a pseudocoelom (body cavity made up of only an ectoderm and endoderm ).
The man tested positive for antibodies to Trichinella, a type of roundworm. Five other family members also developed symptoms such as fevers, headache, stomach pain, diarrhea, muscle pain and ...
Trichinella spiralis. Trichinae (Trichinella spp.) are a genus of nematodes whose larvae migrate into skeletal muscle. Trichinae have no external phase; infection occurs through the consumption of raw muscle meat from an infested animal. In Europe, Trichinella spiralis is most common in domestic animals; Trichinella britovi and Trichinella ...

Tissue-dwelling parasites, such as Trichinella spiralis (cause of trichinosis), rely on new hosts eating the tissues of their current host. For members of the family Onchocercidae whose adults live in the "closed" vertebrate circulatory system , transmission to a new host is achieved by the microfilaria stage, with the help of blood-feeding ...
