[Processes connected with hatching of larvae from eggs of parasitic nematodes]. / Procesy zwiazane z wyleganiem sie z jaj larw nicieni pasozytniczych.

ABSTRACT

Influence of such factors as temperature, pH, CO2 level and oxidation- reduction potential value in the alimentary tract of host on the stimulation of invasive eggs was studied. Changes of these factors lead to change in permeability of inner layer of egg-shell. Then the hatching fluid is released and its enzymes digest the egg-shell. In the nematodes, which have the free-living larvae, the initiation process can depend on parasite or environmental agents.
