Okadaic Acid and Dinophysis Toxins
Bad Bug Book 2nd Edition: Shellfish Toxins (PSP, DSP, NSP, ASP, AZP)
Toxins primarily responsible for DSP are Okadaic Acid (OA), Dinophysistoxin 1 (DTX 1), and Dinophysistoxin 2 (DTX 2). All three of these toxins have a variety of 7-O-acyl ester derivatives that are produced by shellfish and can also cause illness. DSP toxins are produced by select dinoflagellates belonging to the genus Dinophysis and Prorocentrum.
