  • Title: Non-selective retention of PSP toxins by the mussel Mytilus galloprovincialis fed with the toxic dinoflagellate Alexandrium tamarense.

    Journal: Toxicon; 2001 Dec; 39(12):1917-21. PubMed ID: 11600155.
    Abstract:
    Mussels, Mytilus galloprovincialis, were contaminated by paralytic shellfish poisoning (PSP) toxins by being fed with the toxic dinoflagellate Alexandrium tamarense. Temporal variations in the toxin content and the profile of mussels during the feeding experiment were monitored by high-performance liquid chromatography (HPLC). The toxin profile of mussels was compared with that of A. tamarense to clarify the mechanism of uptake of toxins in mussels. The prominent toxins in mussels and A. tamarense were N-sulfocarbamoyl toxins (C1,2) and carbamate toxins, gonyautoxin-1,4 (GTX1,4). The toxin profiles of both mussels and A. tamarense were almost constant throughout the experimental period. There were no remarkable differences in the toxin proportion between mussel and A. tamarense. These results indicate that mussels do not selectively accumulate particular toxins.
