Clam specimens were collected from the culture pond eight days after the outbreak and assayed for the anatomical distribution of lethal potency (as paralytic shellfish poison=PSP). The digestive gland showed the highest potency of 2,000±1,600 (mean±S.E.) MU/g, followed by other parts (160±110 MU/g) and siphon (33±24 MU/g). The lethal potency of the purple clam gradually decreased over one year, resulting in a value of 6±4 MU/g digestive gland in December. The toxin was partially purified from the ethanolic extract of toxic digestive glands, by ultrafiltration and Bio-Gel P-2 column chromatography. TLC, cellulose acetate membrane electrophoresis and !IPLC analyses demonstrated that the toxin consisted almost exclusively of gonyautoxiris 1-4. It was concluded from these results that the causative agent of the above food poisoning was nothing else than PSP. |
