title: [Ploidy of somatic nuclei during life cycle of Myxosporean (Myxozoa, Grasse, 1970)].
abstract: Results of the author's investigation on the ploidy of somatic nuclei in various myxosporean species, throughout different stages of their complicated life cycles, have been summarized. A comparative analysis of data on the ploidy in somatic and generative nuclei of Kudoa quadratum (Multivalvulida) has been given for the first time. Representatives of the Multivalvulida order differ from those of the earlier studied Bivalvulida order in the structure of their myxospore. It has been found that during the myxosporean life cycle alteration of haploid, diploid and polyploid somatic nuclei occurs, and that differentiation of somatic cells and nuclei takes place in both haploid and diploid phases of the life cycle.
