title: Ultrastructural characteristics of the sporogenesis of genus Myxobolus infecting some Nile fishes in Egypt.
abstract: This study presents the ultrastructural characteristics of sporogenesis in the genus Myxobolus which infects four economically important Egyptian fishes: Oreochromis niloticus niloticus, Barbus bynni, Labeo niloticus and Hydrocynus forskalii, specimens of which were collected at Giza city. Although the cysts were observed in different organs, the pattern of sporogenesis was the same. Moreover, the sporogenesis found in the present study followed the usual pattern valid for most of the myxosporean genera studied.
