The most commonly used serodiagnostic antigens for trichinellosis are the excretory-secretory (ES) antigens from T. spiralis muscle larvae (ML), but the specific antibodies against the ML ES antigens are usually negative during early stage of Trichinella infection. The recent studies demonstrated that T. spiralis adult worm (AW) antigens were recognized by mouse or swine . Adult female Trichinella spiralis. The adult female worm is 2–3 mm long and 90 μm in diameter; the male 1–2 mm by 60 μm. Adult worms survive in the small bowel for around 1 month. Females produce larvae after 1 week. (x ).
Trichinosis is infection with Trichinella spiralis or related Trichinella species. Symptoms include initial gastrointestinal irritation followed by periorbital edema, muscle pain, fever, and eosinophilia. Diagnosis is clinical with later confirmation by serologic tests. Muscle biopsy may be diagnostic but is seldom necessary. At present, worms and their products has been shown to have protective effects on immune-mediated diseases. Therefore, we aimed to investigate the effect of the recombination Trichinella spiralis (T. spiralis, Ts) adult serine protease-like protein rTs-ADSp-7 on a 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced CD mouse model.
This process releases cell contents and other fluids that, together with the products of histolysis, are ingested by active pumping of the pharynx. The adults living in the intestine have a stylet as well. However, the adult Trichinella feed on the intestinal mucosa of the host rather than on its intestinal contents. (Gould, ) Primary Diet. Trichinella are the smallest known parasites to infect humans and have a strange life cycle. Small adult worms mature within the intestines of an intermediate host such as a pig. An adult female creates live larvae in batches that bore through the wall of the intestines.
