ABSTRACT
Enteromyxum leei and Enteromyxum fugu, which are myxosporean parasites, were first found in cultured tiger puffer Takifugu rubripes in Korea. We collected four tiger puffers that showed severe emaciation signs for our experiments. DNA sequencing was confirmed that the tiger puffers were coinfected with E. leei and E. fugu. Furthermore, similar amounts of E. leei and E. fugu were confirmed using real-time PCR in the intestine. To the best of our knowledge, there have been no reports of E. fugu infection in the olive flounder Paralichthys olivaceus. However, the diagnosis of inflowing water, discharged water and olive flounder samples using highly sensitive diagnostic methods confirmed the presence of E. fugu in water and fish samples from olive flounder farms near the tiger puffer farm. Therefore, the present study aimed to develop highly sensitive diagnostic methods such as real-time and two-step PCR for early diagnosis and follow-up of the emaciation disease and multiplex PCR for rapid diagnosis. The multiplex PCR method exhibited the same sensitivity as the one-step PCR method developed in this study, demonstrating its efficacy for rapid diagnosis. Therefore, the suggested methods can be utilized for the early diagnosis and rapid diagnosis of emaciation diseases and reduction of economic losses through rapid disease control.
