FIGURES 3–5 in Ultrastructural observations on the development of Ceratomyxa aegyptiaca (Myxozoa: Bivalvulida) infecting Solea aegyptiaca (Pleuronectiformes: Soleidae) from Tunisian coastal lagoon

FIGURES 3–5. Earlier sporogonic stages of Ceratomyxa aegyptiaca Fig. 3. Sporoblast showing two capsulogenic cells (Cc) with its nuclei (CNu) and with a prominent external tube (Et) and a capsular primordium (Cp), a sporoplasmogenic cell (SpC) with two nuclei (SpNu) and laterally two valvogenic cells (Vc) with its nuclei (VNu). Fig. 4. Young capsulogenic cell (Cc) with capsular primordium (Cp) composed of an electron-dense outer layer (1), an electron-lucent median layer (2) and an inner electron-dense core (3). Fig. 5. Immature spore attached to the epithelial cell (Ec) showing capsulogenic cell (Cc) with a prominent external tube (Et) in the cytoplasm and a clup-shaped capsular primordium (Cp) which is surrounded by valvogenic cell (Vc).
