It has been known for many years that Trichinella spiralis initiates infection by penetrating the columnar epithelium of the small intestine; however, the mechanisms used by the parasite in the establishment of its intramulticellular niche in the intestine are unknown. Although the previous observations indicated that invasion also occurs in vitro when the infective larvae are inoculated onto c...

The intestinal phase is critical for trichinellosis caused by Trichinella spiralis (T. spiralis), as it determines both process and consequences of the disease. Several previous studies have reported that T. spiralis induces the initial predominance of a Th1 response during the intestine stage and a subsequent predominance of a Th2 response during the muscle stage. In the present study, immune ...

It has been known for many years that Trichinella spiralis initiates infection by penetrating the columnar epithelium of the small intestine, however, the mechanisms used by the parasite in the establishment of its intramulticellular niche in the intestine are unknown. The recent demonstration that invasion also occurs in vitro when infective larvae of T. spiralis are inoculated onto cultures o...

Schanzel H., E. Hegerova, B. Koudela, V. Lohr: Activity of Creatine-Phosphokinase in the Course of Experimental Trichinellosis. Acta vet. Brno, 47, 1978: 91-95. Activity of serum cteatine-phosphokinase has been determined at different intervals after experimental infestation of mice and guinea pigs by larvae of Trichinella spiralis. Blood samples were treated by Bio-La-test kreatinkinaza Lachem...

Infection of mammalian skeletal muscle cells by Trichinella spiralis causes host nuclei to become polyploid (ca. 4N) and abnormally enlarged. It has been postulated that this enlargement reflects an infection-induced elevation of host transcription. Anthelmintic treatment of T. spiralis-infected rodents with mebendazole (MBZ) causes a reduction in the size of infected cell nuclei and a signific...

Studies of biological properties of newborn larvae of Trichinella spiralis and immune responses against newborn larvae in the host are reviewed. The biological properties of newborn larvae examined are the natural production, migration, surface antigens and their maturity and effects on the host. Various mechanisms of host immunity to newborn larvae are reviewed, including the stage specificity...

Irritable Bowel Syndrome (IBS) is a common multifactorial intestinal disorder for which the aetiology remains largely undefined. Here, we have used a Trichinella spiralis (T. spiralis)-induced model of post-infective IBS, and the effects of probiotic bacteria on gut dysfunction have been investigated using a metabonomic strategy. A total of 44 mice were divided into four groups: an uninfected c...

In order to know the effect of pre-existing Trichinella spiralis infection on experimentally induced intestinal inflammation and immune responses, we induced colitis in T. spiralis-infected mice and observed the severity of colitis and the levels of Th1, Th2, and regulatory cytokines and recruitment of CD4(+)CD25(+)Foxp3(+) T (regulatory T; T(reg)) cells. Female C57BL/6 mice were infected with ...
