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)

Journal of Eukaryotic Microbiology, 2003
ABSTRACT. Fish species around the world are parasitized by myxozoans of the genus Kudoa, several of which infect and cause damage of commercial importance. In particular, Kudoa thyrsites and Kudoa amamiensis infect certain cultured fish species causing damage to muscle tissue, making the fish unmarketable.

Factors affecting sporoplasm release in Kudoa septempunctata

Parasitology Research, 2015
The myxosporean parasite Kudoa septempunctata has been isolated from cultured olive flounder (Paralichthys olivaceus) and was recently identified as a cause of food poisoning in humans. Since the sporoplasm plays an important role in causing diarrhea by invading intestinal cells, the specific factors affecting the release of sporoplasm from spores ...

First report of Kudoa thunni and Kudoa musculoliquefaciens affecting the quality of commercially harvested yellowfin tuna and broadbill swordfish in Eastern Australia

Parasitology Research, 2021
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.

Detection of Kudoa hexapunctata and Kudoa neothunni from retail raw tuna in Japan using a novel duplex polymerase chain reaction

Parasitology International, 2020
Kudoa hexapunctata was taxonomically separated from Kudoa neothunni, but their main host is tuna. K. hexapunctata has been identified as causative agent of foodborne diseases associated with the ingestion of raw Pacific bluefin tuna (PBT) in Japan, but K. neothunni has not.

Survivability of Kudoa septempunctata in human intestinal conditions

Parasitology Research, 2016
To elucidate whether Kudoa septempunctata was able to live in the human intestine, we assessed viability of K. septempunctata sporoplasms under conditions that mimicked human and ragworm digestive tracts. To study the effect of osmotic pressure on viability, sporoplasms were incubated in 0.9 or 3.4 % sodium chloride solutions, which roughly ...

Cryopreservation of Kudoa septempunctata sporoplasm using commercial freezing media

Parasitology Research, 2016
Cryopreservation methods for Kudoa septempunctata have not been established. This prevents an effective study of K. septempunctata, which cannot be artificially cultivated in the laboratory. In this study, we attempted to establish a cryopreservation method for K.

Sporogenesis and spore structure in Kudoa lunata (Myxosporea, Multivalvulida)

Parasitology Research, 1988
The multivalvulid myxosporean Kudoa lunata Lom, Dyková and Lhotáková, 1983 forms large polysporic trophozoites within the myocytes of scaldfish, Arnoglossus imperialis and A. laterna. The spores arise by the division of generative cells that produce a number of sporogonic cells necessary to complete a sporoblast.

Multivalvulidan myxosporeans from marine fishes in Nha Trang Bay, Vietnam, with descriptions of Kudoa igori n. sp. and Kudoa borimiri n. sp. from mullets

Parasitology Research, 2022
In March and April 2018, we carried out a survey of myxosporean parasites in coastal fishes collected from Nha Trang Bay in Vietnam's East Sea. Of the 159 fish specimens, 18 fish species were represented, belonging to 10 families. In 8 host species, 7 myxosporean species were found, representing the genera Kudoa and Unicapsula.

Kudoa lunata n. sp. (Myxozoa, Myxosporea) and notes on the nature of muscular “cysts” of the genus Kudoa

Archiv für Protistenkunde, 1983
Summary Kudoa lunata n. sp. has been described from skeletal muscles of 3 species of scaldfish, Arnoglossus imperialis, A. laterna and A. thori . Spores are stellate with 4 blunt, upward lifted tips, with 4 sharp apical projections, their width is 10 (9–11.4) µm, length 5.3 (4.5–6.2) µm.

Development of a multiplex PCR to detect Kudoa spp. and to distinguish Kudoa septempunctata in olive flounder Paralichthys olivaceus

Aquaculture, 2016
Abstract Since the identification of Kudoa septempunctata as a causative agent of human food poisoning, Kudoa infections have become a serious concern in the aquaculture of olive flounder ( Paralichthys olivaceus ). In order to ensure the safety of cultured flounder, various methods have been developed to detect K . septempunctata .
