Dinophysis Toxins: Causative Organisms, Distribution and Fate in Shellfish
Several Dinophysis species produce diarrhoetic toxins (okadaic acid and dinophysistoxins) and pectenotoxins, and cause gastointestinal illness, Diarrhetic Shellfish Poisoning (DSP), even at low cell…
Production and release of yessotoxins by the dinoflagellates Protoceratium reticulatum and Lingulodinium polyedrum in culture.

Current knowledge on the origin, producer organisms and vectors, chemical structures, metabolism, biosynthetic origin, toxicological properties, potential risks to human health and advances in detection methods of YTXs are covered.
Yessotoxins profile in strains of Protoceratium reticulatum from Spain and USA.
Morphogenetic diversity and biotoxin composition of Alexandrium (Dinophyceae) in Irish coastal waters
Toxin profiles of natural populations and cultures ofAlexandrium minutum Halim from Galician (Spain) coastal waters
Toxin profiles obtained from natural populations during different PSP outbreaks in different rías and from cultures are fairly consistent and suggest that at least from the toxin point of view, A. minutum was the PSP agent during the toxic outbreak in May 1984.
Separation of chlorophylls and their degradation products in marine phytoplankton by reversed-phase high-performance liquid chromatography
SummaryAn RP-HPLC procedure which separates chlorophylls and their degradation products is described. By employing an amonium acetate buffered mobile phase and a linear gradient elution, complex…

- 1 January 1997
A substantial proportion of bacteria from five Alexandrium cultures originally isolated from various countries produced sodium channel blocking (SCB) toxins, as ascertained by mouse neuroblastoma assay, and the chemical nature of the SCB toxins in selected bacterial isolates was determined as paralytic shellfish toxins.
Toxin and molecular analysis of Gymnodinium catenatum (Dinophyceae) strains from Galicia (NW Spain) and Andalucía (S Spain)
Differences in toxin content and RAPD profile between the isolates of G. catenatum are probably not linked to the location in which the strains were collected, and this region has been used before for the detection of intraspecific variability.
