Antigenic analysis of Strongyloides ratti infective larvae and adult worms.
The protein composition of Strongyloides ratti infective larvae and adult worms extracted sequentially in water, sodium deoxycholate and sodium dodecyl sulphate (SDS) and their excretory/secretory products were analysed by both one- and two-dimensional SDS-polyacrylamide gel electrophoresis. While many bands common to all preparations and both stages of the worm were seen, a number of bands uni...
متن کاملStrongyloides ratti in mice
C57B1/6 mice were infected with Strongyloides ratti. Susceptibility to infection was ascertained by quantifying the numbers of larvae in the faeces 1 week after infection. Resistance to infection was transferred by pooled immune serum and mesenteric lymph node (MLN) cells obtained 2 and 3 weeks after infection. There was no additive effect when immune serum and MLN cells were given together. Pr...
متن کاملElectron microscopical studies of Strongyloides ratti infective larvae: loss of the surface coat during skin penetration.
Previous indications using radiolabelled larvae that Strongyloides ratti free-living infective larvae lose a surface coat during penetration of the skin were further investigated by transmission electron microscopy of the cuticle of S. ratti infective larvae in the free-living stage, after penetration of mouse skin, and after migration to the lungs. These studies demonstrated the presence of a ...
متن کاملHost-finding behavior of Strongyloides stercoralis infective larvae to sodium cation, human serum, and sweat.
The host-finding behavior of Strongyloides stercoralis infective larvae was examined by in vitro agarose assay method. As human body fluid contains 0.85% (ca 0.15 molar) NaCl, various concentrations of sodium chloride, from 0.5M to 0.01M (7 steps), were examined. Many larvae were attracted at concentrations between 0.5 and 0.05M of sodium chloride. The concentration of 0.05M attracted the most ...
متن کاملStrongyloides ratti and S. venezuelensis – rodent models of Strongyloides infection
Strongyloides spp. are common parasites of vertebrates and two species, S. ratti and S. venezuelensis, parasitize rats; there are no known species that naturally infect mice. Strongyloides ratti and S. venezuelensis overlap in their geographical range and in these regions co-infections appear to be common. These species have been widely used as tractable laboratory systems in rats as well as mi...
