A revlew of the pathogenic impact of Myxosporea in marine fish culture is presented. At least 11 species of Bivalvulida and 7 species of Multi\~alvulida have been described in marine or brackish fish kept in different culture systems. The pathological importance of these myxosporoses is discussed, and their potential importance with the growth of culture facilities is stressed. 
Myxobolus sp. can cause in vivo myoliquefaction in the host Paralichthys orbignyanus (Osteichthyes, Paralichthydae).
We found intense myoliquefaction in vivo among specimens of wild and farmed South American flatfish Paralichthys orbignyanus Valenciennes, 1839. The soft flesh condition was attributed to MyxobolusExpand
Host-Parasite Interaction of a Gill-Infecting Didymozoid in the Pazhayar, Southeast Coast of India
Trematodes of the family Didymozoid are parasites of marine fishes. The infection effects of the parasitic digenean trematode on the gill region of the fish Rastrelliger kanagurta were examined.
A case of high mortality due to heavy infestation of Ceratomyxa diplodae in sharpsnout sea bream (Diplodus puntazzo) treated with reproductive steroids
A case of 100% mortality in cultured sharpsnout sea bream (Diplodus puntazzo) caused by Ceratomyxa diplodae after sustained steroid treatment for induction of sex inversion is described. TheExpand
Diseases of White Sea Bream (Diplodus sargus L.) Reared in Experimental and Commercial Conditions in Greece
The study showed that D. sargus reared under captive conditions is prone to several parasitic and bacterial infections, amongst them the most important in terms of pathology were the myxosporeans (Myxobolus sp. and Kudoa sp). Expand
Ceratomyxa sparusaurati (Protozoa: Myxosporea) infections in cultured gilthead sea bream Sparus aurata (Pisces: Teleostei) from Spain: aspects of the host-parasite relationship
In fish from stocks showing external disease signs and trickling mortalities, parasite stages invaded other organs and were responsible for cell-mediated host reaction and important tissue injuries, therefore, C. sparusaurati can be considered a potential threat for some Sparus aurata-growing systems.

Host–parasite interaction of a muscle-infecting didymozoid in the Atlantic mackerel Scomber scombrus L.
Genomic DNA isolation, PCR amplification, cloning, and sequencing strongly supported the view that the eggs belong to a yet unidentified didymozoid. Expand

The importance of these parasites is discussed and the need for further studies on infections in Brazilian fish is emphasized because of the high economic impact of some Kudoa species which cause liquefaction in hosts' muscles and render these fish unsuitable for consumption. Expand
Histopathology and immunohistochemistry of gills of Van fish (Alburnus tarichi Güldenstädt, 1814) infected with myxosporean parasites
It was determined that the density and size of mucocytes in the infected areas of the gill tissue increased, whereas the number of mitochondria-rich cells decreased, and Hsp70, an indicator of stress, was not different between normal and infected fish. Expand
Updated of the Pathologies Affecting Cultured Gilthead Seabream , Sparus aurata
Among other Sparidae species, the gilthead seabream Sparus aurata is the most important fish species in the Mediterranean aquaculture, achieving good growth performances and progressive increasedExpand
Necrotizing myositis associated with parasitism by Myxobolus sp. (Myxozoa) in the palate of the violet goby, Gobioides broussonnetii (Gobiidae), from Marajó Island, Brazil
The macro- and microscopic findings of the present study confirm the presence of necrotizing myositis in the palate of G. broussonnetii associated with parasitism by Myxobolus sp. Expand


Biology Contravenes Taxonomy in the Myxozoa: New Discoveries Show Alternation of Invertebrate and Vertebrate Hosts
Experimental results provide evidence that, instead of being considered as representatives of separate classes in the phylum Myxozoa, the myxosporean and actinosporean are alternating life forms of a single organism. Expand
Light and electron microscopic description of Sphaerospora dicentrarchi n. sp. (Myxosporea : Sphaerosporidae) from wild and cultured sea bass, Dicentrarchus labrax L
. A new myxosporean, Sphaerospora dicentrarchi n. sp., was found in numerous organs of wild and cultured sea bass (Dicentrarchus labrax L.). It is distinguished from all previously reportedExpand
Kudoasis of Cultured Yellowtail
Through various field studies and experiments a hypothesis is possible that the source of infection of kudoasis in yellowtails cultured in Ryukyu and Amami waters may be the above-mentioned coral fishes and yellowtails may become seriously infected by eating coral fishes bearing sporulated trophozoites of the myxosporidia which happen to swim into net pens for yellowtails.

Reservoir hosts and new clupeoid host records for the myoliquefactive myxosporean parasite Kudoa thyrsites (Gilchrist)
Flesh spoilage due to the liquefactive effects of the parasite could occur in any of these hosts, and was seen here in S. sagax neopilchardus, S. robustus and E. japonicus in association with mature spores. Expand
Sphaerospora epinepheli n. sp. (Myxosporea: Sphaerosporidae) observed in grouper (Epinephelus malabaricus).
Blood stages, similar to C-blood protozoans observed from freshwater fish in Europe, were found from peripheral blood smears of grouper and electron dense bodies were observed in the cytoplasm of the primary cell blood stages. Expand
Sphaerospora araii n. sp. (Myxosporea: Sphaerosporidae) from the kidney of a longnose skate (Raja rhina Jordan and Gilbert) from the Pacific Ocean off Canada
A new species of Sphaerospora is described from the lumen of the kidney tubules of Raja rhina collected from the Pacific Ocean off British Columbia, Canada, and the pattern of valvular ornamentation is illustrated. Expand
