AbstractAbstract AbstractSummary PDFSupplementary Material
After publishing results of a study that revealed diarrheagenic and emetic activity in 4-5-day old mice infected with <i>Kudoa septempunctata</i> (<i>K. septempunctata</i>) spores, the Korea Centers for Disease Control and Prevention reported 11 events of “<i>Kudoa</i> food poisoning” in 2015. The epidemiological design of the previous study was descriptive rather than analytical; therefore, this study aimed to further investigate the pathogenicity of <i>K. septempunctata</i>. Academic articles showing evidence of the pathogenicity of <i>K. septempunctata</i> were searched via PubMed using the citation discovery tool. Information regarding the kinds of experimental animals and inoculum spores used, as well as study results were extracted. Four articles evaluating the pathogenicity of Myxospran parasites were selected; the first article suggested the pathogenicity of <i>K. septempunctata</i>, while the remaining three articles reported no abnormal symptoms or histopathologic changes. Our findings indicate that there is weak evidence supporting the pathogenicity of <i>K. septempunctata</i>. Further studies evaluating the pathogenicity of <i>K. septempunctata</i> are needed urgently.
Korean summary
“질병관리본부는 2015년 쿠도아충 환자 사례조사 (cases reports)를 발표하였다. 제주산 광어에서 발견되는 칠성쿠도아충이 급성 식중독을 일으키는 병인 원충이라는 주장과 관련한 병인성 (pathogenicity) 근거들을 정리한 결과 실험실적 근거에 일관성이 없었다. 이렇게 실험실적 근거가 불충분한 상황에서, 오직 환자사례 결과들만으로 칠성쿠도아충을 급성식중독의 역학적 인과성 (epidemiologic causality)을 부여하는 것은 과학적 타당성이 떨어진다.”
