Further Advance of Gambierdiscus Species in the Canary Islands, with the First Report of Gambierdiscus belizeanus [PDF]

, 2020
Ciguatera Poisoning (CP) is a human food-borne poisoning that has been known since ancient times to be found mainly in tropical and subtropical areas, which occurs when fish or very rarely invertebrates contaminated with ciguatoxins (CTXs) are consumed ...

Gambierdiscus polynesiensis from New Caledonia (South West Pacific Ocean): Morpho-molecular characterization, toxin profile and response to light intensity

Harmful Algae
Gambierdiscus is known to produce neurotoxins associated with ciguatera poisoning (CP). In New Caledonia (NC), South West Pacific Ocean, there is currently a significant knowledge gap regarding CP and the microalgae linked to this foodborne illness. This study describes a new strain of Gambierdiscus polynesiensis, 19PV93, isolated from the west coast ...

Maitotoxin-4, a Novel MTX Analog Produced by Gambierdiscus excentricus [PDF]

, 2017
Maitotoxins (MTXs) are among the most potent toxins known. These toxins are produced by epi-benthic dinoflagellates of the genera Gambierdiscus and Fukuyoa and may play a role in causing the symptoms associated with Ciguatera Fish Poisoning.

Polyketide synthesis genes associated with toxin production in two species of Gambierdiscus (Dinophyceae) [PDF]

, 2015
Background Marine microbial protists, in particular, dinoflagellates, produce polyketide toxins with ecosystem-wide and human health impacts. Species of Gambierdiscus produce the polyether ladder compounds ciguatoxins and maitotoxins, which can lead to ...

Transcriptomic characterisation and genomic glimpse into the toxigenic dinoflagellate Azadinium spinosum, with emphasis on polykeitde synthase genes [PDF]

, 2015
Background: Unicellular dinoflagellates are an important group of primary producers within the marine plankton community. Many of these species are capable of forming harmful algae blooms (HABs) and of producing potent phycotoxins, thereby causing ...

Multiple sodium channel isoforms mediate the pathological effects of Pacific ciguatoxin-1 [PDF]

, 2017
Human intoxication with the seafood poison ciguatoxin, a dinoflagellate polyether that activates voltage-gated sodium channels (NaV), causes ciguatera, a disease characterised by gastrointestinal and neurological disturbances. We assessed the activity of
