| Abstract: | The early stages and capsulogenetic stages of sporogenesis ofMyxobolus kwangsiensis were studied in detail by electron microscopy.M. kwangsiensis is an intracellular myxosporean infecting the epithelial cells of kidney tubules of young daceLabeo rohita. TheM. kwangsiensis sporogensis presents the typical features of myxosporea. The initial stages are multinucleate primary cells, with one primary
cell typically enclosing one secondary cell. The secondary cells are formed directly by cytokinesis inside the primary cells.
The primary cell participates in the formation of the secondary cell nucleus. The nuclear division of primary cell is asynchronous
by amitosis. The parasitic organisms may degenerate inside the epithelial cells at any stage. The modes of sporoblast formation,
the typical features of myxosporea and the cause of its degradation are discussed.
