title: [Role of mollusks as benthos components in the purification of water bodies from the eggs of Ascaris suum].
abstract: Fresh water mollusks Galba palustris and Bithynia tentaculata feed on ascaris eggs, destroy them (10 to 20%) and hinder their development as compared to control ones. Thus, this mollusks participate in the purification of water bodies from ascaris eggs. Eggs swallowed by mollusks of the genus Radix develop normally. Consequently Radix serve for scattering eggs over the bottom of the water body.
