title: [Effects of some species of hydrocoles on the development of ascarid eggs].
abstract: The study established that aquatic plants differently affected the development of ascarid eggs. Some species of algae exerted a damaging effect on ascarid eggs only at early stages of embryogenesis while others did at its late stages, but some species did not produce any noticeable effect on the development of the eggs. A great difference was found in the development of ascarid eggs in different seasons. Gas exchange conditions were ascertained to affect the development of ascarid eggs. Analysis of the effect of egg lysozyme versus mollusk one on ascarid embryogenesis demonstrated that the latter had a more pronounced antiparasitic activity.
