[Microscopic analysis of the effect of mercuric salts on the parasite concentration in feces].
The fixation of mercuric ions on the uterin layer of the Ascaris lumbricoides egg wall is proved by light microscopic histochemical technics and electron microscopic microanalysis. These observations support the hypothesis of a possible reaction between the egg surface components and those of the dilution reagents. This reaction is used in the methods of concentration in coprology. In the case of mercuric salts, the free thiol components which are missing in all the Ascaris egg wall layers are not the factors of the reaction.
