采用小鼠麻痹性贝类毒素（PSP）生物测定法，研究了麻痹性贝类毒素在23种甲藻中的毒性分布。特别考虑了形成红潮的物种和以前被认为是麻痹性贝类中毒的致病生物的那些物种。在这些被调查的物种中，有十种是Gonyaulax属的海洋物种，以前已知含有三种有毒物种。PSP仅在Catenella部分的Gonyaulax种中检测到。毒素的含量在不同的物种中有所不同，从0.05到24 pg/细胞不等。在新英格兰赤潮物种G. tamarensis var. excavata Braarud中，每个细胞的毒素量也随生长阶段（指数或平稳）而变化。
Using the mouse bioassay for paralytic shellfish poison (PSP), the distribution of toxicity among 23 dinoflagellate species was studied. Special consideration was given to red-tide-forming species and to those species previously implicated as causative organisms in paralytic shellfish poisoning. Among those investigated were ten marine species of the genus Gonyaulax, previously known to contain three toxic species. The presence of PSP was detected only in Gonyaulax species of the section Catenella. The amount of toxin varied in different species, ranging from 0.05 to 24 pg/cell. The amount of toxin per cell also varied with the phase of growth (exponential or stationary) in the New England red-tide species, G. tamarensis var. excavata Braarud.
