TRINCHINOSIS:
Also called Trichinosis.A disorder resulting from infestation with the small roundworm Trichella spiralis, the said disease is commonly acquired by humans by the eating of undercooked pork, which contains encapsulated larvae of the parasites.
It comes from pork’s stomach and small intestines and when the capsular coating is digested the liberated larvae in turn unvade the mucosal lining of the small intestines. And they become adults within a week.
After fertilization the female worm deposits larvae into the mucosa and sometimes directly into the lymphatic, from which the larvae reach the blood and are carried to all parts o fthe body, notably the burrows of skeletal muscles, where they reach the encapsulating stage.
The muscles most open invaded are those of the diaphgram, eyes, neck, throat, larynx,a nd tounge. In the muscles, the larval capsules, or cysts, may remain for years, eventually becoming calcified .( Hardened like salt).
Only small percentage of infected persons however, have sufficient parasites to produce recognizable clinical symptoms, which include diarrhea, vomiting, nausea, and fever in the clearly stage, followed later by pain, stiffness and swelling of various muscular structures,a nd often, edema ( swelling of the face).
Treatment consists of the use of anti-inflammatory drugs for symptomatic relief; thiabendazole has been reported to be highly effective in destroying the parasites in the digestive tract.There is however no practical method of the large scale detection of trichinous pork and the surest safeguard remains the thorough cooking of pork.
TRICHINA
Plural Trichinae or Trichinas ( species trichinella spiralis), parasitic worm of the class Nematoda ( phylum Aschelminthes) that causes trichinosis (q.v.), a serious disease in humans and other mammals- e.g., pigs, cats, dogs, bears, foxes, and rats,
The worm, which occours al over the world, ranges in length from 1.5 to 4 mm (0.06 to 0.2 inch)
Mating takes place in the host’s small intestine, after which the fertilized female trichinae burrow into the intestinal wall and release the larvae, which in turn, are transported by the bloodstream to all parts of the body.
The worm grows within the muscle tissue, requiring approximately 16 days maturing. A cyst thereafter, develops around the larvae’s body.And eventually multiply if the muscles tissue containing the encysted larvae- is eaten by an appropriate host. The worm matures and reproduces in the hosts intestines…..
