Since the identification ofKudoaseptempunctataas a causative agent of human food poisoning,Kudoainfections 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 detectK.septempunctata. However, less attention has been paid for inspection and detection of otherKudoaspecies. To date, sixKudoaspp. have been reported from olive flounder, 3 species each from the trunk muscle, 2 species from the brain, and one species from the heart. During our routine inspection of cultured olive flounder, we isolated severalKudoaspecies includingKudoa igamiandKudoa ogawaiin addition to the list of previously reported species. In the present study, a multiplex PCR (mPCR) was developed to detect allKudoaspp. known to date from olive flounder in Japan. The mPCR also differentiateK.septempunctataamong otherKudoaspp. simultaneously. The developed mPCR successfully detected sevenKudoaspp. and differentiatedK. septempunctatawith a sensitivity of 103myxospores. Thus, mPCR offers a reliable and relatively simple method to detectKudoainfection in olive flounder, specifically aiming to identifyK.septempunctatainfection.Statement of RelevanceOlive flounderParalichthys olivaceusis one of the most important fish species for commercial aquaculture and fishery trading in Japan and Korea. Infections of microscopic myxozoan parasite of genusKudoa(Myxozoa: Multivalvulida) has become a serious concern in flounder culture since the recent identification ofKudoa septempunctataas a causative agent of human food poisoning. Although various detection methods have been developed for the inspection ofK. septempunctata, relatively little attentions are given to otherKudoaspp. We addedK. ogawaiandK. igamito the list ofKudoaspp. infecting olive flounder and developed multiplex PCR to simultaneously detectKudoaspp. and distinguishK. septempunctata. This offers relatively simple and method to inspectKudoaspp. in cultured flounder.
