Global distribution of ciguatera causing dinoflagellates in the genus Gambierdiscus
Toxicon, 2010Dinoflagellates in the genus Gambierdiscus produce toxins that bioaccumulate in tropical and sub-tropical fishes causing ciguatera fish poisoning (CFP). Little is known about the diversity and distribution of Gambierdiscus species, the degree to which individual species vary in toxicity, and the role each plays in causing CFP.

A study of toxin production by Gambierdiscus toxicus in culture
Toxicon, 1986The dinoflagellate Gambierdiscus toxicus was cultivated under different environmental conditions. By an improved toxin extraction procedure the toxicity of methanol extracts was evaluated. Medium composition, temperature decrease, origin (clonal or not clonal) and culture age did not significantly modify toxin production.

Metabolic relationships of uncultured bacteria associated with the microalgae Gambierdiscus
Environmental Microbiology, 2019Summary Microbial communities inhabit algae cell surfaces and produce a variety of compounds that can impact the fitness of the host. These interactions have been studied via culturing, single‐gene diversity and metagenomic read survey methods that are limited by culturing biases and fragmented genetic ...

The effects of light intensity on the growth of Japanese Gambierdiscus spp. (Dinophyceae)
Harmful Algae, 2016Marine toxic dinoflagellates of the genus Gambierdiscus are the causative agents of ciguatera fish poisoning (CFP), a form of seafood poisoning that is widespread in tropical, subtropical and temperate regions worldwide. The distributions of Gambierdiscus australes, Gambierdiscus scabrosus and two phylotypes of Gambierdiscus spp. type 2 and type 3 have

à propos de gambierdiscus toxicus
Revue Française des Laboratoires, 2002Resume Des irritations parfois invalidantes des muqueuses oculaires et nasales, apparues chez des individus travaillant sur le cote ocean d'un atoll, semblent dues a la presence, dans les embruns, de Gambierdiscus toxicus, dont la concentration anormale serait due a un remaniement du massif corallien.

Gambierone, a Ladder-Shaped Polyether from the Dinoflagellate Gambierdiscus belizeanus
Organic Letters, 2015A new natural product named gambierone (1) was isolated from the cultured dinoflagellate Gambierdiscus belizeanus. The structure of this compound features an unprecedented polyether skeleton and an unusual right-hand side chain. Its relative configuration was fully determined by interpretation of ROESY experiment and comparison between experimental and

Evaluation of Gambierdiscus survival after exposure to ballast water
Harmful Algae, 2011Abstract The dinoflagellate Gambierdiscus was exposed to ballast water from a trans-oceanic vessel, and maintained at a variety of temperatures in the dark to determine if viability would be maintained. Logarithmically growing Gambierdiscus inocula were admixed (1:6, vol:vol) with ballast water, maintained in the dark at 22.6 °C, 24.6 °C, 26.8 °C and
