A fat-soluble toxin was found in the muscle of an amberjack, Seriola aureovittata, which had caused the human illness at Katsuura on May 10, 1967. The symptoms in both human beings and test animals showed a close similarity to those of ciguatera, but slight differences were also observed. The toxic fish were found in a high frequency among the amberjack caught at the fishing ground called “Mashone” and the larger fish seems to be more toxic. As test animals, cats and mice were used and the partial purification of the toxin was carried out by chromatography using silicic acid, DEAE-cellulose, and Sephadex LH-20. The toxin showed a resemblance to ciguatoxin(s) isolated from Gymnothorax javanicus or Lutjanus bohar in the chromatographic behaviors. The most purified toxin was lethal to mice at a level of 20 r/g.
