We then infected the turbots in artifi cial laboratory settings with pure cultured U . marinum . The infected turbots showed syndromes similar to those observed in naturally infected ones. Furthermore, microscopic examination and PCR detection confi rmed the presence of the ciliate in the tissues of those laboratory-infected turbots. To our best knowledge, this is the fi rst report of scuticociliatosis caused by U . marinum in farm-raised turbot S . maximus in China.展开更多
