TRICHINELLA SPIRALIS IN AN AGRICULTURAL ECOSYSTEM. III. EPIDEMIOLOGICAL INVESTIGATIONS OF TRICHINELLA SPIRALIS IN RESIDENT WILD AND FERAL ANIMALS

Infectivity of Trichinella Spiralis Larvae

Time of survival and infectivity of Trichinella spiralis larvae in pig muscle tissue, buried at various depths in the ground were assessed. In the pork pieces the number of infective larvae was 250 ML/g. Meat originated from pig halves was divided in 39 equal pieces, 0.7 kg each, disposed in three groups of 1 3, and buried in depths of 30, 50, and 100 centimeters respectively. The pork was dug ...

Experimental and immunological comparison of Trichinella spiralis and Trichinella nativa

Transformation of lymphocytes from animals sensitized to Trichinella spiralis.

Biology and genome of Trichinella spiralis.

Clade I nematode species in the genus Trichinella can cause infections in humans that lead to mortality and serious morbidity. There are currently eight recognized species or genotypes that comprise this genus. The species display diverse biological characteristics, the evolutionary significance of which recently has been extensively clarified. Some of that diversity translates into variable im...

Eosinophils and resistance to Trichinella spiralis

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.
