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 ...
متن کاملCharacterisation of novel protein families secreted by muscle stage larvae of Trichinella spiralis☆
Proteins secreted by Trichinella spiralis have a potential role in remodelling host skeletal muscle. However, whilst many parasite-secreted proteins have been identified, it has rarely been demonstrated that these are secreted into the nurse cell. Using an informatics-based analysis, we have searched the T. spiralis expressed sequence tag (EST) datasets for cDNAs encoding potential secreted pro...
متن کاملMolting, ecdysis, and reproduction of Trichinella spiralis are supported in vitro by intestinal epithelial cells.
Trichinella spiralis is an obligate parasite of animals that has an unusual intracellular life cycle. Investigation of parasitism at the cellular and molecular levels has been challenging because of a shortage of tools for in vitro cultivation of T. spiralis. We have found that T. spiralis larvae molt, ecdyse, develop to adulthood, and reproduce when they are inoculated onto cultured intestinal...
متن کاملInvasion of intestinal epithelia in vitro by the parasitic nematode Trichinella spiralis.
Studies of nematode establishment in intestinal niches has been hindered by the lack of a readily manipulated in vitro assay. In this report, experiments are described wherein the larval stage of the parasitic nematode Trichinella spiralis was shown to invade epithelial cell monolayers in vitro. Larvae penetrated cells and migrated through them, leaving trails of dead cells in their wake. Cells...
متن کاملProteolytic enzymes secreted by larval stage of the parasitic nematode Trichinella spiralis.
Excretory/secretory products (ES), collected from in vitro cultures of muscle larvae (L1) of Trichinella spiralis (Owen, 1835) were examined for the presence of proteolytic enzymes. Several discrete proteinases in the size range of 25-55 kDa were identified by substrate gel electrophoresis and were characterised according to pH optima, substrate specificity and inhibitor sensitivity using azoca...
