DSP toxin contents inDinophysis fortii and scallops collected at Mutsu Bay, Japan

Journal of Applied Phycology, 1996
Cell densities of toxic phytoplankton species responsible for diarrhetic shellfish poisoning (DSP) were monitored at a sampling site in Mutsu Bay, Japan, in 1995.Dinophysis fortii almost completely dominated the toxic phytoplankton community. Okadaic acid (OA) and dinophysistoxin-1 (DTX1) contents in bothD.

Proteomic profile in Perna viridis after exposed to Prorocentrum lima, a dinoflagellate producing DSP toxins

Environmental Pollution, 2015
In the current study, we compared protein profiles in gills of Perna viridis after exposure to Prorocentrumlima, a dinoflagellate producing DSP toxins, and identified the differential abundances of protein spots using 2D-electrophoresis. After exposure to P. lima, the level of okadaic acid (a main component of DSP toxins) in gills of P.

Occurrence of diarrhetic shellfish poisoning (DSP) toxins in clams (Ruditapes decussatus) from Tunis north lagoon

Environmental Monitoring and Assessment, 2011
The main diarrhetic shellfish toxins, okadaic acid (OA) and dinophysistoxin-1, 2 (DTX-2, 2) were detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS) as pyrenacyl esters in clams (Ruditapes decussatus) collected in Tunis north lagoon from January 2007 to June 2008.

Accumulation, biotransformation, ways of excretion and depuration kinetics of DSP toxins in bivalves.

2023
No abstracts are to be cited without prior reference to the author. Bivalves accumulate DSP toxins mainly in free forms and esterified with fatty acids (7-o-acyl derivatives, “DTX3”). In most bivalve species studied to date as the cockle Cerastoderma edule or several clams as Venerupis pullastra, Spisula solida, or Ruditapes philippinarum, 7-o-acyl ...

Biosynthetic studies of the DSP toxin DTX-4 and an okadaic acid diol ester

Journal of the Chemical Society, Chemical Communications, 1995
Stable isotope incorporation experiments with 13C- and 18O-labelled precursors show that all the carbon atoms in DTX-4 2 and an okadaic acid diol ester 3 are derived from acetate and glycolate, and also identify the acetate and glycolate derived oxygen atoms.

DSP toxin production de novo in cultures of Dinophysis acuminata (Dinophyceae) from North America

Harmful Algae, 2009
For decades, many aspects of Dinophysis biology have remained intractable due to our inability to maintain these organisms in laboratory cultures. Recent breakthroughs in culture methods have opened the door for detailed investigations of these important algae.

P-glycoprotein expression in Perna viridis after exposure to Prorocentrum lima, a dinoflagellate producing DSP toxins

Fish & Shellfish Immunology, 2014
Bivalves naturally exposed to toxic algae have mechanisms to prevent from harmful effects of diarrhetic shellfish poisoning (DSP) toxins. However, quite few studies have examined the mechanisms associated, and the information currently available is still insufficient.

Sulfated diesters of okadaic acid and DTX-1: Self-protective precursors of diarrhetic shellfish poisoning (DSP) toxins

Harmful Algae, 2017
Many toxic secondary metabolites used for defense are also toxic to the producing organism. One important way to circumvent toxicity is to store the toxin as an inactive precursor. Several sulfated diesters of the diarrhetic shellfish poisoning (DSP) toxin okadaic acid have been reported from cultures of various dinoflagellate species belonging to the ...

Occurrence of Prorocentrum lima, a DSP toxin-producing species from the Atlantic coast of Canada

Journal of Applied Phycology, 1992
A species of Prorocentrum (Dinophyta, Prorocentrales), isolated from a phytoplankton net sample from the Atlantic coast of Nova Scotia, has been brought into unialgal culture. The sample was collected at an aquaculture site immediately following an incident of diarrhetic shellfish poisoning (DSP) due to the consumption of contaminated mussels.
