Given the rising economic losses associated with scuticociliatosis in olive flounder (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Paralichthys olivaceus<\/jats:italic>\n                    <\/jats:styled-content>\n                    ) cultured in Korea, alternative species such as starry flounder (\n                    <jats:styled-content style=\"fixed-case\">\n                      <jats:italic>Platichthys stellatus<\/jats:italic>\n                    <\/jats:styled-content>\n                    ), which demonstrates resistance to certain pathogens affecting olive flounder, are being considered for aquaculture. However, the underlying biological mechanisms influencing host susceptibility to\n                    <jats:italic>M. avidus<\/jats:italic>\n                    remain unclear. In this study, we investigated differences in susceptibility to\n                    <jats:italic>M. avidus<\/jats:italic>\n                    between olive flounder and starry flounder by evaluating their serum scuticocidal activity. Our results revealed that starry flounder serum exhibited significantly higher scuticocidal activity against\n                    <jats:italic>M. avidus<\/jats:italic>\n                    compared to olive flounder serum. The observed activity was largely abolished following heat inactivation or EDTA\/EGTA treatment, indicating that the alternative complement pathway plays a crucial role in the scuticocidal activity. Proteomic analysis using two\u2010dimensional gel electrophoresis (2\u2010DE) and mass spectrometry identified a higher abundance of complement component C3 and leucine\u2010rich repeat (LRR) proteins in starry flounder serum. Although the scuticocidal activity of olive flounder serum was significantly lower than that of starry flounder serum, the haemolytic activity against heterologous erythrocytes was significantly higher in olive flounder. This suggests that\n                    <jats:italic>M. avidus<\/jats:italic>\n                    may possess a mechanism that suppresses the scuticocidal activity of olive flounder serum. This is further supported by the observation that the scuticocidal activity of fresh starry flounder serum was significantly reduced after\n                    <jats:italic>M. avidus<\/jats:italic>\n                    was incubated with heat\u2010inactivated olive flounder serum prior to exposure.

contribute to the development of more effective control strategies for scuticociliatosis.\n
