a powerful heat-stable low molecular weight neurotoxin synthesized and secreted by certain dinoflagellates, such as species of Gonyaulax, which accumulates in the tissue of bivalve mollusks feeding on the dinoflagellates; it may cause a severe toxic reaction called shellfish poisoning in those who ingest contaminated mollusks.
A potent neurotoxin found in shellfish, such as the mussel or the clam (and sometimes the pufferfish, Sphoerides nephelus), produced by the dinoflagellate Gonyaulax catenella, which is ingested by the shellfish; the cause of cases of poisoning from eating the California sea mussel (Mytilus californianus), scallop, and the Alaskan butterclam (Saxidomus giganteus).
saxitoxin/saxi·tox·in/ (sak´sĭ-tok″sin) a powerful neurotoxin synthesized and secreted by certain dinoflagellates, which accumulates in the tissues of shellfish feeding on the dinoflagellates and may cause a severe toxic reaction in persons consuming contaminated shellfish.
A potent neurotoxin produced by certain dinoflagellates that accumulates in shellfish feeding on these organisms and consequently causes food poisoning in humans who eat the shellfish.
a powerful neurotoxin found in bivalve mollusks, including mussels, clams, and scallops. It is produced by certain species of dinoflagellates, which are consumed by the mollusks. Saxitoxin may cause a severe food intoxication in humans who eat the contaminated shellfish.
A potent neurotoxin found in shellfish, such as the mussel or the clam, produced by the dinoflagellate Gonyaulax catenella, which is ingested by the shellfish; the cause of poisoning due to eating California sea mussels, scallops, and Alaskan butterclams.
