Recent anecdotal reports from seafood processors in eastern Australia have described an increased occurrence of post-mortem myoliquefaction ('jellymeat') in broadbill swordfish Xiphias gladius, and macroscopic cysts throughout the musculature of yellowfin tuna Thunnus albacares. A genus of parasitic cnidarians, Kudoa (Myxosporea, Multivalvulida), species of which are known to occur in economically important wild-caught fish species globally, can cause similar quality-deterioration issues…

First Report of Three Kudoa Species from Eastern Australia: Kudoa thyrsites from Mahi mahi (Coryphaena hippurus), Kudoa amamiensis and Kudoa minithyrsites n. sp. from Sweeper (Pempheris ypsilychnus)
TLDR
Through morphological and molecular analyses, the presence of both K. thyrsites and K. amamiensis are confirmed in eastern Australian waters and a novel Kudoa species was identified, having stellate spores, with one polar capsule larger than the other three.
Incidence of three Kudoa spp., K. neothunni, K. hexapunctata, and K. thunni (Myxosporea: Multivalvulida), in Thunnus tunas distributed in the western Pacific Ocean
TLDR
A new host record of the longtail tuna for K. neothunni and K. hexapunctata is provided and a high prevalence of the seven-SV/PC myxospore morphotype of K. Neoth unni is revealed in this tuna host.
Morphological and molecular identification of a new Kudoa thyrsites isolate in Mediterranean silver scabbardfish Lepidopus caudatus.
TLDR
The findings suggest that K. thyrsites is the primary cause of myoliquefaction in silver scabbardfish from the Alboran Sea, and a set of new allometric characters is proposed as additional descriptors for more accurate and specific description of kudoid myxospores.
First taxonomic description of multivalvulidan myxosporean parasites from elasmobranchs: Kudoa hemiscylli n.sp. and Kudoa carcharhini n.sp. (Myxosporea: Multivalvulidae)
TLDR

KUDOA IWATAI (MYXOSPOREA: MULTIVALVULIDA) IN WILD AND CULTURED FISH IN THE RED SEA: REDESCRIPTION AND MOLECULAR PHYLOGENY
TLDR
It is concluded that K. iwatai is an Indo-Pacific species that, in the Red Sea, has extended its host range to include the allochthonous gilt-head sea bream, European sea bass, and grey mullet and is apparently native to the region.

A review of Kudoa-induced myoliquefaction of marine fish species in South Africa and other countries
TLDR
Myoliquefaction of fish musculature results in customer quality complaints and in huge economic losses, especially with regard to Pacific hake, farm- reared Atlantic salmon, South African pilchards and Cape snoek.
TWO UNUSUAL MYXOZOANS, KUDOA QUADRICORNIS N. SP. (MULTIVALVULIDA) FROM THE MUSCLE OF GOLDSPOTTED TREVALLY (CARANGOIDES FULVOGUTTATUS) AND KUDOA PERMULTICAPSULA N. SP. (MULTIVALVULIDA) FROM THE MUSCLE OF SPANISH MACKEREL (SCOMBEROMORUS COMMERSON) FROM THE GREAT BARRIER REEF, AUSTRALIA
TLDR
Two unusual myxozoan parasites are described from the somatic muscle of 2 reef fishes from Australia's Great Barrier Reef andylogenetic analysis showed that these parasites cluster within a clade comprised of Kudoa species, bringing into question the division of parasites of the Multivalvulida into genera based solely on polar capsule numbers.
Morphological and molecular genetic characterization of two Kudoa spp., K. musculoliquefaciens, and K. pleurogrammi n. sp. (Myxosporea: Multivalvulida), causing myoliquefaction of commercial marine fish
TLDR
Molecular genetic characterization of kudoid species with the potential to induce post-mortem myoliquefaction will facilitate the reliable and specific identification of myxosporeans found in either jellied or normal muscles of important commercial fish.
