Abstract
Nucleotid sequences of internal transcribed spacers (ITS1 and ITS2) of rDNA were obtained and analyzed in populations of Planorbarius corneus snails from Leningradskaya Oblast and Kaliningradskaya Oblast. Close similarity between ITS1 and ITS2 of the snails from different areas proved the fact that Planorbarius corneus was a polymorphic but a uniform species.
