Mast cell-deficient W/Wv mice and their mast cell-sufficient littermates were given infections of Trichinella spiralis. W/Wv mice were slower than their littermates to expel adult T. spiralis. Repair of the mast cell deficiency of W/Wv mice by bone marrow grafting was accompanied by accelerated expulsion of T. spiralis.

PURPOSE The production of IgE increases in parasitic invasions, triggering local or systemic inflammatory response with the involvement of blood platelets. The aim of the study was to assess the number and morphological parameters of blood platelets as well as their phagocytic and bactericidal activity in patients with Trichinella spiralis infection. It is interesting to investigate the blood p...

Pigs infected with T. spiralis and T. britovi were followed by double (IgG) and triple antibody ELISA (IgG1, IgG2 and IgM) during a 12-week-period. Specific IgG and IgG1 responses were similar and showed a significant relation with the infecting doses and intensity of infection. Response to T. britovi was slightly lower than in groups infected with the same dose of T. spiralis. IgG2 response wa...

Trichinella spiralis is an intracellular nematode parasite of mammalian skeletal muscle. Infection of the muscle cell leads to the formation of a host-parasite complex that results in profound alterations to the host cell and a re-alignment of muscle-specific gene expression. The role of parasite excretory-secretory (ES) proteins in mediating these effects is currently unknown, largely due to t...

This review summarizes the major biological, biochemical and molecular methods which have been developed during last 20 years to distinguish parasites of the genus Trichinella. From the time of the discovery of Trichinella in 1835 until the 1970, it was assumed that trichinellosis was caused by a single species of parasite, Trichinella spiralis. Many biological parameters have been compared to ...

Trichinella spiralis infection is the major problem all over world. The trichinosis being human zoonotic disease has been subject of current research collected by many tours different localities. scheme identification based on “Systema helminthumˮ Vol III Yamaguti (1959).This study adds epidemiology and rediscovery in Aurangabad district.

Many aspects of the biology and epidemiology of Trichinella infection in the horse are poorly understood, including survival of Trichinella spp in horse muscle. In this study, we have assessed the freeze tolerance of T. spiralis in horse meat stored at 5, -5, and -18 degrees C for 1 day to 24 weeks. Results demonstrate a steady reduction in the number of live ML recovered from the cold stored m...

Mice infected with Trichinella spiralis were depleted of eosinophils by repeated administration of rabbit anti-mouse eosinophil serum. There was no effect on the spontaneous expulsion of adult worms from the small intestines, but the numbers of larvae in the muscles were almost doubled. It is concluded that eosinophils contribute to resistance to the systemic phase of trichinosis.

Twelve Merino sheep were experimentally shown to be susceptible to infection with Trichinella spiralis or T. pseudospiralis by feeding on infected carcasses of mice or by oral intubation with recovered muscle larvae. The larvae recovered from the sheep showed variable tissue distribution. The diaphragm and tongue were most affected. The viability of the recovered larvae was confirmed by success...
