How can tricinella inspire a blood vesel to form around it's cyst?
Answers:
Do you mean "Trichinella"?
Trichinosis is infection with Trichinella spiralis or related Trichinella species. Symptoms include initial GI irritation followed by periorbital edema, muscle throbbing, fever, and eosinophilia. Diagnosis is clinical and with serologic tests. Muscle biopsy may be diagnostic but is seldom basic. Treatment is with mebendazole or albendazole plus prednisone if symptoms are severe.
Trichinosis occurs worldwide. In addition to the classic agent T. spiralis, trichinosis can be cause by T. pseudospiralis , T. nativa , T. nelsoni, and T. britovi. The life cycle is maintained by animals that are fed (eg, pigs, horses) or put away (eg, bears, foxes, boars) other animals whose striated muscles contain encysted infective larvae (eg, rodents). Humans become infected by eating natural, undercooked, or processed meat from infected animals, most commonly pigs, wild boar, or bear. Larvae undergo excystation surrounded by the small bowel, penetrate the mucosa, and become adults in 6 to 8 days. Mature females release living larvae for 4 to 6 wk and consequently die or are expelled. Newborn larvae migrate through the bloodstream and body but ultimately survive only within striated skeletal muscle cell. Larvae fully encyst in 1 to 2 mo and remain viable for several years as intracellular parasites. Dead larvae eventually are resorbed or calcify. The cycle continues solitary if encysted larvae are ingested by another carnivore. Source(s): http://en.wikipedia.org/wiki/Trichinella
