Synopsis of the species of Ceratomyxa Thélohan, 1892 (Myxozoa: Myxosporea: Ceratomyxidae)

Abstract

A synopsis of the species of Ceratomyxa Thélohan, 1892 (Myxozoa: Myxosporea: Ceratomyxidae), including a total of 147 species, is presented. For each species the relevant morphological and morphometric data are indicated, as well as the site of infection within the host and the original hosts and locality. A diagrammatic illustration of the spores is also provided.

Molecular identification of cryptic species of Ceratomyxa Thélohan, 1892 (Myxosporea: Bivalvulida) including the description of eight novel species from apogonid fishes (Perciformes: Apogonidae) from Australian waters

“…Only a single species has been found, as confirmed by SSU rDNA, in multiple hosts; C. talboti was reported from five pomacentrid species at Lizard Island, GBR, Australia ). An additional 34 Ceratomyxa species have been described from multiple hosts but these are characterised on the basis of spore morphology alone (see Eiras 2006). Molecular evidence that only closely related hosts (i.e.…”

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

“…Despite the numerous descriptions relating to the genus Ceratomyxa, only C. anguillae, C. hilsae, C. hongtzensis, C. hungarica and C. shasta are known to infect freshwater teleosts, none of which are from the South American region (Eiras 2006, Lom & Dyková 2006. With the exception of C. shasta, which is histozoic (Noble 1950), all the other freshwater species of the genus Ceratomyxa are coelozoic (Chakravarty 1939, Tuzet & Ormières 1957, Hsieh & Chen 1984, Molnár 1992).…”

“…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.…”

“…108(2): 150-154, April 2013 The genus Ceratomyxa Thélohan, 1892, constitutes one of the largest genera within the class Myxosporea of the phylum Myxozoa, comprising about 190 species, the great majority of which are coelozoic parasites infecting the gall bladder of marine teleosts (Eiras 2006, Lom & Dyková 2006. Ceratomyxa spp have elongated, crescent-shaped or arcuate spores with shell valves that are frequently conical, exceeding in length the axial diameter of the spore.…”

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

“…Sometimes the spore containing binucleate sporoplasm does not completely fill the spore cavity and also, two uninucleate sporoplasms were reported (Lom and Dykova 1992). These parasites have a worldwide distribution and parasitize a wide range of fish species, usually infecting the gall bladder of the host (Eiras 2006). Also, Eiras (2006) listed 147 species of this parasite.…”
