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

Diarrhetic Shellfish Poisoning
What is Diarrhetic Shellfish Poisoning (DSP)? DSP is caused by certain toxins produced by marine organisms. These organisms, in large concentration, are often referred to as “harmful algal blooms”Expand

Structures and Configurations of Ciguatoxin from the Moray Eel Gymnothorax javanicus and Its Likely Precursor from the Dinoflagellate Gambierdiscus toxicus
Ciguatoxin (CTX) is the toxic principle of ciguatera, which is responsible for the most widespread food poisoning of nonbacterial origin. The toxin, isolated from the moray eel Gymnothorax javanicus,Expand

Isolation and structural elucidation of the causative toxin of the diarrhetic shellfish poisoning.
The major toxin involved in the diarrhetic shellfish poisoning was isolated from the hepatopancreas of the mussel Mytilus edulis and was named dinophysistoxin-1. It was obtained as a colorless solid:Expand
