Determination of diarrhetic shellfish toxins in various dinoflagellate species

Jong Soo Lee, +5 more
- 01 Aug 1989 - 
TL;DR: Sixteen species of unialgal samples of dinoflagellate, either wild or cultured, were tested for production of diarrhetic shellfish toxins such as okadaic acid, dinophysistoxin-1 (DTX1), and pectenotoxins (PTXs), and PTX2 was the only toxin detected among PTX family.
Journal ArticleDOI

CHARACTERIZATION OF OSTREOPSIS AND COOLIA (DINOPHYCEAE) ISOLATES IN THE WESTERN MEDITERRANEAN SEA BASED ON MORPHOLOGY, TOXICITY AND INTERNAL TRANSCRIBED SPACER 5.8S rDNA SEQUENCES

Antonella Penna, +6 more
- 01 Feb 2005 - 
TL;DR: In this study, genetic markers combined with morphology and toxicity analyses was useful in the taxonomic and phylogenetic studies of the Ostreopsidaceae in a temperate area.
Journal ArticleDOI

Gambierdiscus and Ostreopsis: Reassessment of the state of knowledge of their taxonomy, geography, ecophysiology, and toxicology

Michael L. Parsons, +6 more
- 01 Feb 2012 - 
TL;DR: In this paper, a review of the state of knowledge on these genera is presented, with particular emphasis on the validation or dismissal of earlier findings in light of these revisions, and the review is divided into four sections (taxonomy, geography, ecophysiology, and toxicology).
Journal ArticleDOI

Production and release of yessotoxins by the dinoflagellates Protoceratium reticulatum and Lingulodinium polyedrum in culture

Beatriz Paz, +4 more
- 01 Sep 2004 - 
TL;DR: Although YTX was detected in culture medium, with this study it was not possible to explain which is the release mechanism of the toxin in the medium, and larger amounts of toxins were observed in the cellular fraction and in the culture medium at the last stage of the culture in both species.
Journal ArticleDOI

Gambierdiscus excentricus sp. nov. (Dinophyceae), a benthic toxic dinoflagellate from the Canary Islands (NE Atlantic Ocean)

Santiago Fraga, +5 more
- 01 Nov 2011 - 
TL;DR: The Neuroblastoma cell-based assays for ciguatoxins (CTX) and maitotoxin (MTX) confirmed G. excentricus as a CTX- and MTX-like compounds producer.
