目的了解膝沟藻毒素中毒流行病学特征,探讨预防和救治麻痹性贝毒中毒的措施;方法对中毒者进行调查,采集样品、观察藻种并计数密度,检测菲律宾蛤仔毒力,测定麻痹性贝毒毒素成分;结果养殖菲律宾蛤仔的海水中亚历山大藻密度为5×105细胞/L,病人食剩的生、熟菲律宾蛤仔毒力分别为16 603 MU/100 g和4 035 MU/100 g,样品中均检出GTX1,GTX2,GTX3,GTX4。结论菲律宾蛤仔引起的中毒事件是一起贝类膝沟藻毒素中毒。
Objective To understand the epidemiological characteristics of kyrgylus algal toxins and to explore the measures to prevent and treat the poisoning of paralytic shellfish poisoning. Methods The poisoning persons were surveyed, the samples were collected, the algal species were counted and the density was counted to test the toxicity of the clams in the Philippines, The results showed that the density of Alexandriumcens in seawater of Ruditapes philippinarum was 5 × 10 5 cells / L, the viability of raw and cooked Ruditapes philippinarum was 16 603 MU / 100 g and 4 035 MU / 100 g, GTX1, GTX2, GTX3, GTX4 are all detected in the sample. Conclusion The poisoning caused by Ruditapes philippinarum is a toxin of molluscicide in shellfish.
