Occurrence of a new type of shellfish poisoning in the Tohoku district.
E Epidemiological data indicated that as little as 12 MU of toxin was enough to induce a mild form of poisoning in humans, and this remarkable toxicity of shellfishes was recognized only in the areas around Motoyoshi-cho, Miyagi Prefecture. Expand

Sixteen species of unialgal samples of dinoflagellate, either wild or cultured, were tested for production of diarrhetic shellfish toxins such as okadaic acid, dinophysistoxin-1 (DTX1), and pectenotoxins (PTXs), and PTX2 was the only toxin detected among PTX family. Expand
Diarrhetic shellfish toxins
Abstract As the causative agents of a new type of shellfish poisoning, named diarrhetic shellfish poisoning, okadaic acid, 35(S)-methylokadaic acid, 7-O-acyl derivatives of 35(S)-methylokadaic acid,… Expand
Gymnodimine, a new marine toxin of unprecedented structure isolated from New Zealand oysters and the dinoflagellate, Gymnodinium sp.
Abstract A new marine toxin, gymnodimine, was isolated from New Zealand oysters, Tiostrea chilensis, and the dinoflagellate Gymnodinium cf. mikimotoi. Its unique structure was elucidated by… Expand
Azaspiracid, a New Marine Toxin Having Unique Spiro Ring Assemblies, Isolated from Irish Mussels, Mytilus edulis.
Diarrhetic Shellfish Poisoning
DSP is caused by certain toxins produced by marine organisms, in large concentration, that can contaminate certain seafood and result in poisoning when humans eat such seafood. Expand
Isolation and structure of yessotoxin, a novel polyether compound implicated in diarrhetic shellfish poisoning
Abstract A novel polyether toxin, yessotoxin, was isolated from scallops implicated in diarrhetic shellfish poisoning, and its planar structure 1 was proposed by means of modern NMR techniques.
Fluorometric Determination of Diarrhetic Shellfish Toxins by High-Performance Liquid Chromatography
Two principal toxins of diarrhetic shellfish poisoning, okadaic acid and dinophysistoxin-1, were esterified with 9-anthryldiazomethane in methanol. After cleaning with a Sep-pak silica cartridge… Expand
Origins of ciguatera fish poisoning: a new dinoflagellate, Gambierdiscus toxicus Adachi and Fukuyo, definitively involved as a causal agent.

The dinoflagellate Gambierdiscus toxicus which had been previously isolated in the Gambier Islands (French Polynesia) from toxic biodetritus covering dead corals provides a presumptive argument for a common worldwide origin for ciguatera. Expand
Two analogs of azaspiracid isolated from mussels, Mytilus edulis, involved in human intoxication in Ireland.
Two new analogs of azaspiracid were isolated from mussels collected at Arranmore Island, Ireland in 1997 as additional causes of human intoxication by NMR and negative ion FAB CID MS/MS experiments. Expand
