Diarrhetic Shellfish Poisoning

Recent insights about relationships between nutrient availability, forms, and stoichiometry, and the distribution, ecophysiology, and food web effects of pelagic and benthic Prorocentrum species

“…Until the past $decade, benthic Prorocentrum species were not linked to death of wild or cultured fish (see Ajuzie, 2002, and references therein), despite the fact that OA can accumulate in fish tissues (Edebo et al, 1992) and shellfish can cause DSP in humans who consume the contaminated seafood (e.g., Kat, 1979;Langeland et al, 1984;Freudenthal and Jijina, 1985;Aune and Yndstad, 1993, and references therein). Ajuzie (2008) contributed compelling information toward testing the hypotheses that toxic strains of the P. lima complex can negatively affect the behavior of juvenile fish, and can cause their mortality; and that feeding this harmful alga to fish during blooms of other harmful algal species promotes fish death.…”

A novel sensitive cell-based Love Wave biosensor for marine toxin detection

“…Meanwhile, hyperphosphorylation of cytoskeleton or junctional moieties that regulate solute permeability is favored. All these can cause a sodium release and a subsequent passive loss of fluids, which is responsible for the diarrheic symptoms (Aune and Yndestad 1993). Besides, some studies carried out on animals have identified OA as a tumor promoter and also proved its mutagenic and immunotoxic effects (Campàs et al 2007).…”

The 2008 Texas Dinophysis ovum bloom: Distribution and toxicity

“…First described in the 1960s, symptoms include gastrointestinal distress, such as diarrhea, nausea, and vomiting, with onset from 3 to 12 h following ingestion of the contaminated organism (Aune and Yndestad, 1993). No DSP-related human deaths have been recorded, and recovery time for intoxication is around 3 days (Blanco et al, 2005;Hallegraeff, 2003).…”
