| ultrastructural characteristics of the sporogenesis of genus myxobolus infecting some nile fishes in egypt. | 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 myxosporea ... | 2004 | 15616860 |
| the light microscopy and ultrastructural characteristics of myxobolus naffari (myxosporea, myxobolidae) infecting the nile carp labeo niloticus (cyprinidae) and its histological impact | during a survey of myxosporean parasites infecting freshwater fishes from the river nile at giza governorates, egypt between march and september 2016, nine out of 30 specimens of the nile carp labeo niloticus (cyprinidae) were found to be naturally infected with myxobolus naffari (myxobolidae). small macroscopic plasmodia appeared embedded in the host gill tissue accompanied with fusion of the gill epithelia, and atrophy was observed at the site of infection. the host reaction was manifested by ... | 2018 | 29274208 |
