In the present study, we morphologically and genetically characterized kudoid infection in a flathead (Platycephalus sp.) fished in the Seto Inland Sea of Japan, off Hofu, Yamaguchi Prefecture, and a Japanese jack mackerel (Trachurus japonicus) fished in the Sea of Japan, off Hagi, Yamaguchi Prefecture. The kudoid species forming white cysts in the musculature of the aforementioned fish were Kudoa iwatai and Kudoa trachuri, respectively. We report here, for the first time, the sequencing of the internal transcribed spacer regions of K. iwatai and K. trachuri. Their usability for analyses of intraspecific variation is briefly discussed.enKudoa iwataiKudoa trachuriMultivalvulidaMyxosporeacommercial marine fishflatheadJapanesejack mackerelrDNAArticle
