Four new species of Ceratomyxa Thelohan 1892 (Myxozoa: Myxosporea: Ceratomyxidae) infecting the gallbladder of some Red Sea fishes

Abstract

Four new Ceratomyxa species were described from the gallbladder of four Red Sea fishes at Suez and Hurghada, Egypt. These species are Ceratomyxa bassoni sp. n. from Plectorhinchus gaterinus (Forsskal 1775) at Suez and Hurghada, Ceratomyxa entzerothi sp. n. from Valamugil seheli (Forsskal 1775) at Suez and Hurghada, Ceratomyxa swaisi sp. n. from Saurida undosquamis (Richardson 1848) at Suez only and Ceratomyxa hurghadensis sp. n. from Fistularia commersonii Ruppell 1838 at Hurghada only. Their taxonomic affinities to other species are discussed.

Ceratomyxa tunisiensis n. sp. (Myxosporea: Bivalvulida) from the Gallbladders of Two Carangid Fish Caught Off the Coast of Tunisia

“…These species are: C. arcuata Thélohan, 1892; C. truncata Kudo ; C. australis et Kovaleva, ; C. obesa Jameson, 1929; C. milleri Gunter, Whipps and Adlard ; C. diplodae Lubat et al. ; C. ghaffari Ali, Abdel‐Baki, et Sakran ; C. dehoopi Reed, Basson, Van As et Dykova ; C. bassoni Abdel‐Ghaffar, Ali, Al Quraishy, Al Rasheid, Al Farraj, Abdel‐Baki & Bashtar, . Ceratomyxa arcuata differs in having relatively larger spores (13.5 × 38 vs. 6.4 × 25) with valves having tapered ends.…”

Molecular and Morphometric Characteristics of Ceratomyxa hamour n. sp. (Myxosporea: Bivalvulida) Infecting the Gallbladder of the Orange‐spotted Grouper Epinephelus coioides from the Arabian Gulf, Saudi Arabia

“…These are: Ceratomyxa bassoni Abdel‐Ghaffar et al. from Plectorhynchus gaterinus (Haemulidae) in the Red Sea; C. buri Yokoyama and Fukuda from cultured yellowtail Seriola quinqueradiata (Carangidae) in Japan; Ceratomyxa flexa Meglitsch from Plagiogenion rubiginosus (Emmelichthyidae) in the Pacific Ocean; Ceratomyxa gibba Meglitsch from Congiopodus leucopaecilis (Congiopodidae) in the Pacific Ocean; Ceratomyxa honckenii Reed et al. from Amblyrhynchotes honckenii (Tetraodontidae) in South Africa; Ceratomyxa ireneae Heiniger and Aldlard, from Archamia fucata (Apogonidae) in the Great Barrier Reef in Australia; Ceratomyxa recta Meglitsch from Genypterus blacodes (Ophidiidae) in the Pacific Ocean in New Zealand; Ceratomyxa sparusaurati SitjÀ‐Bobadilla et al.…”

Ultrastructural description of Ceratomyxa microlepis sp. nov. (Phylum Myxozoa): a parasite infecting the gall bladder of Hemiodus microlepis, a freshwater teleost from the Amazon River

“…Although all other currently known species of Ceratomyxa infecting freshwater fish lack elongated lateral projections, there are about 70 marine species of Ceratomyxa in which such projections have been described (Ali et al 2006, Eiras 2006, Abdel-Ghaffar et al 2008, Gunter & Adlard 2008, 2009, Gunter et al 2010. Morphological comparison to these marine species suggested that C. microlepis sp.…”
