[Biological characteristics of the invasive stage of Myxosoma cerebralis (Myxosporidia: Myxosomatidae)].
The data concerning biological peculiarities of spores of Myxosoma cerebralis obtained by the author and other researchers are summarized. The life cycle of M. cerebralis is well adapted to the seasonal cycle of the host owing to the fact that the infectivity of the spores is attained only after 4 months of aging in water and that the spores are highly resistive to freezing and drying. No sexual process during 4 month aging was observed. It is supposed that the maturity of spores depends to a great extent on the ability of polar capsules for extrusion.
