Is there evidence thatKudoa septempunctatacan cause an outbreak of acute food poisoning?
After publishing results of a study that revealed diarrheagenic and emetic activity in 4-5-day old mice infected withKudoa septempunctata(K. septempunctata) spores, the Korea Centers for Disease Control and Prevention reported 11 events of "Kudoafood poisoning" in 2015. The epidemiological design of the previous study was descriptive rather than analytical; therefore, this study aimed to further investigate the pathogenicity ofK. septempunctata. Academic articles showing evidence of the pathogenicity ofK. septempunctatawere 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 ofK. septempunctata, while the remaining three articles reported no abnormal symptoms or histopathologic changes. Our findings indicate that there is weak evidence supporting the pathogenicity ofK. septempunctata. Further studies evaluating the pathogenicity ofK. septempunctataare needed urgently.
