“…In Africa, about 135 species of this parasite are currently known to infect fresh and brackish water fishes (Kostoingue et al 2001). However, the marine myxosporean species are scarcely investigated in Africa and few studies were carried out on marine fish, e.g., Fantham (1919Fantham ( , 1930, Fall et al (1997), Ali et al (2001Ali et al ( , 2003. The present work is continuing this effort by the investigation of myxosporean parasites of the Red Sea in Egypt.…”

A new myxosporean parasite, Myxobolus lubati n. sp., was described from the wall of the intestine of haffara seabream Rhabdosargus haffara (Forsskal 1775), Red Sea, Egypt. Macroscopic plasmodia of about 300 mum diameter were located in the circular muscle layer of the intestine. The spores were ovoid and sometimes ellipsoid and measured 9.8 x 7.2 mum. The shell wall of the spore was thickened at the posterior end and marked with 5-7 sutural markings. Polar capsules were equal and pyriform with three polar filament turns situated in the posterior half of the polar capsule. Polar capsules measured 4.2 x 1.6 mum. Histological evaluation of the infection revealed a slight distention of the intestinal layer of muscularis. Ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.

A new myxosporean parasite, Myxobolus stomum n. sp., is described from the oral cavity and lips of the blackspotted grunt Plectorhynicus gaterinus (Forsskal, 1775) in the Red Sea, Egypt. The parasite was observed as tiny aggregates of whitish cysts hardly noticed within the muscles of the oral cavity, especially within the lips. The spores were subspherical and measured 8.5x6.5 microm. Polar capsules were equal, pear-shaped, occupied about half of the spore length and measured 4.4x2.4 microm. Histological evaluation of the infection revealed no significant impact on the host. The ultrastructure of the plasmodial wall and sporogenesis of the present species followed the usual pattern valid for most studied myxosporean species.

“…However, on the basis of morphological and di-mensional comparison of the spores, only eight species of them could be compared with our species (Table I). M. rohdei (Lom and Dyková 1994) and M. goreensis (Fall et al 1997) can be easily distinguished from the present species by having larger spore, shorter polar capsules and lacking of the sutural makings. Also, M. chiungchowensis (Chen and Ma 1998) can be separated from the present species in having wider spores, higher number of polar filament turns (6-8 vs 3-4) and lacking the sutural markings.…”

A new myxosporean, Myxobolus egyptica sp. nov., was described from the gills of the hornlip mullet Oedalechilus labiosus, collected from the Red Sea at Al-Quseir city, Egypt. The prevalence of infection was 12/72 (16.66%). Myxobolus egyptica was identified on the basis of spore morphometry, histology and transmission electron microscopy. It was distinguished from all previously reported Myxobolus spp. by its shape, dimensions of the mature spore 10.0 ± 0.6 (9.5-10.5) µm in length, 8.5 ± 0.4 (8.0-9.0) μm in width and 8.7 ± 0.5 (8.4-9.2) μm in thickness, polar capsules, locality and host. The parasite formed intrafilamental cyst-like plasmodia. These plasmodia caused curling and atrophy of the gill lamellae. The ultrastructural analysis revealed a double-unit plasmodial membrane which was in direct contact with the host cells and had numerous vesicles. Some mitochondria were found below this membrane. The disporic pansporoblast was earliest recognizable stage of sporogenesis. Advanced developmental stages of spores and mature spores were reported.
