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 .

First report of Kudoa species in the somatic muscle of the Japanese parrotfish Calotomus japonicus (Scaridae) and a description of Kudoa igami , n. sp. (Myxozoa: Multivalvulida)

Parasitology Research, 2014
Three species of the Kudoid parasite (Myxozoa: Multivalvulida) were observed in the somatic muscle of Japanese parrotfish Calotomus japonicus caught off the coast of western Japan. All three species formed pseudocysts in myofibers and caused subclinical infections. The three Kudoa species were distinguished by spore morphology, as well as their 18S and

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.

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.

Synopsis of the species of Kudoa Meglitsch, 1947 (Myxozoa: Myxosporea: Multivalvulida)

Systematic Parasitology, 2014
A synopsis of the species of Kudoa Meglitsch, 1947 (Myxozoa, Myxosporea, Multivalvulida) is presented, including 95 nominal species. For each species the most relevant morphological and morphometric features are indicated in tabulated format. Included are data on the site of infection within the host, the type-host and type-locality, plus a full ...

Characterization of the ribosomal RNA gene of Kudoa neothunni (Myxosporea: Multivalvulida) in tunas (Thunnus spp.) and Kudoa scomberi n. sp. in a chub mackerel (Scomber japonicus)

Parasitology Research, 2013
Kudoa neothunni is the first described Kudoa species having six shell valves and polar capsules, previously assigned to the genus Hexacapsula Arai and Matsumoto, 1953. Since its genetic analyses remain to be conducted, the present study characterizes the ribosomal RNA gene (rDNA) using two isolates from a yellowfin tuna (Thunnus albacares) with post ...

A Kudoa septempunctata antigen induces production of IgE in BALB/c mice

Parasitology Research, 2017
Kudoa septempunctata, a myxosporean parasite, is the causative agent of a foodborne illness associated with consumption of raw Paralichthys olivaceus (olive flounder). Because the lag phase of this illness is short (from 1 to 12 h), it is possible that an allergic response is relevant to this illness. To test whether a K.

Anisakis simplex and Kudoa sp.: Evaluation of specific antibodies in appendectomized patients

Experimental Parasitology, 2008
High prevalence and intensity of infection with anisakid larvae has been reported in commercially important fish in Spain. Likewise, Kudoa-infected fish have lately been detected in both fresh and frozen fish. In the present study the possible relation between appendectomy and specific antibodies to these fish parasites was investigated.

Seroprevalence of anti-Kudoa sp. (Myxosporea: Multivalvulida) antibodies in a Spanish population

Parasitology Research, 2006
A majority of Kudoa species infect the somatic muscle of fish establishing cysts. Because there is no effective method to detect infected fish without destroying them, these parasitised fish reach the consumer. The elevated humoral responses detected previously by us in BALB/c mice immunised with Kudoa sp.

[Study of Tea and Coffee on Inactivation of Kudoa septempunctata].

Shokuhin eiseigaku zasshi. Journal of the Food Hygienic Society of Japan, 2019
The inhibition of Kudoa septempunctata by green tea extract, black tea extract, and coffee extract were studied. Incubation of about 104 Kudoa spores with green tea extract, black tea extract, or coffee extract at 25℃ for 4 hr reduced the survival ratio of Kudoa to 0%.
