Biology and genome of 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...

Nurse cell Biology of Trichinella spiralis

Trichinella spiralis is unique among all known nematodes in being the only species to occupy an intra-multicellular niche in the body of its host. Like developing tumours they also need to recruit new blood vessels towards the developing nurse cells to meet the ever-growing demand of nutrients. Like viruses they highjack the cell machinery and physiology so as to ensure their growth. Thus, inte...

Experimental and immunological comparison of Trichinella spiralis and Trichinella nativa

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 ...

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.
