This web page discusses Paralytic Shellfish Poisoning (PSP), a marine toxin disease with both gastrointestinal and neurologic symptoms reported worldwide. It is caused predominantly by the consumption of contaminated shellfish. Gonyaulacoid dinoflagellates are the source of PSP marine toxins. These unicellular dinoflagellates develop algal blooms throughout the world and produce at least 12 toxins which are tetrahydropurines, and heat and acid stable. Saxitoxin was the first characterized and the best understood. This page describes clinical presentation of PSP (including symptoms), diagnosis, management and treatment, the chemical structure of saxitoxin, molecular mechanism of action, and references.
