1998年1月底，熊本县阿马库萨群岛宫内河口湾的野生牡蛎Crassostrea gias被PSP毒死，可能是由于链状裸藻，其细胞密度为308个/毫升。牡蛎的毒性分数为3.0~263 MU/g可食部分。PSP的高效液相色谱分析表明，牡蛎和甲藻的毒素组成相似，主要毒素为C1(PX1)和C2(PX2)，次要毒素为GTX5、GTX6、dcGTX2、dcGTX3和dcSTX，这些结果表明宫内河口湾、麻库萨、熊本等地的牡蛎是通过食物链被链球藻毒化的。
At the end of January 1998, wild oysters, Crassostrea gigas, in Miyanokawachi Bay, Amakusa Islands, Kumamoto Prefecture were toxified with PSP probably due to Gymnodinium catenatum, whose cell density was 308 cells/mL. The toxicity score of the oysters ranged from 3.0 to 263MU/g of the edible portion. Toxin compositions of the oysters and the dinoflagellate by high performance liquid chromatographic analysis for PSP resembled each other, consisting of C1 (PX1) and C2 (PX2) as the major toxins and, GTX5, GTX6, dcGTX2, dcGTX3 and dcSTX as the minor toxins.From these results, it was concluded that toxic oysters in Miyanokawachi Bay, Amakusa, Kumamoto had been toxified by G. catenatum through the food chain.
