Risk of ciguatoxins is shaped by Gambierdiscus community structure. [PDF]
PLoS ONECiguatoxins (CTXs) are produced by marine microbial eukaryotes (Gambierdiscus/Fukuyoa, Dinophyta: Alveolata) that live epiphytically on macroalgae and other substrates. When CTXs accumulate in seafood they cause Ciguatera Poisoning (CP), which affects ca.

Targeted Metabolite Fingerprints of Thirteen Gambierdiscus, Five Coolia and Two Fukuyoa Species [PDF]
Marine DrugsThe genus Gambierdiscus produces an array of bioactive hydrophilic and lipophilic secondary metabolites that range in mode of action and toxicity. In this study, the metabolite fingerprint was mapped for thirteen Gambierdiscus, five Coolia and two ...

Morphological, Toxicological, and Biochemical Characterization of Two Species of Gambierdiscus from Bahía de La Paz, Gulf of California [PDF]
Marine DrugsWe describe five new isolates of two Gambierdiscus species from Bahía de La Paz in the southern Gulf of California. Batch cultures of Gambierdiscus were established for morphological characterization using light microscopy (LM) and scanning electron ...

Gambierdiscus and Its Associated Toxins: A Minireview [PDF]
Toxins, 2022 Gambierdiscus is a dinoflagellate genus widely distributed throughout tropical and subtropical regions. Some members of this genus can produce a group of potent polycyclic polyether neurotoxins responsible for ciguatera fish poisoning (CFP), one of the ...

Characterizing the Influence of a Heterotrophic Bicosoecid Flagellate Pseudobodo sp. on the Dinoflagellate Gambierdiscus balechii [PDF]
Toxins, 2023 Microbial interactions including competition, mutualism, commensalism, parasitism, and predation, which can be triggered by nutrient acquisition and chemical communication, are universal phenomena in the marine ecosystem.

Emerging occurrence of Gambierdiscus carolinianus in the Azores: The northernmost Atlantic record
Limnology and Oceanography LettersThe dinoflagellate genus Gambierdiscus was detected for the first time in the Azores Archipelago, representing its northernmost record to date (> 39°N). Two strains were isolated from macroalgal substrates on Corvo and Faial Islands during the summer of ...

A General Food Chain Model for Bioaccumulation of Ciguatoxin into Herbivorous Fish in the Pacific Ocean Suggests Few Gambierdiscus Species Can Produce Poisonous Herbivores, and Even Fewer Can Produce Poisonous Higher Trophic Level Fish [PDF]
ToxinsWe adapt previous conceptual and numerical models of ciguateric food chains for the bioaccumulation of Pacific-ciguatoxin-1 (P-CTX-1) to a general model for bioaccumulation of P-CTX3C by parrotfish (Scarus frenatus, S. niger, and S.
