Using artificial substrates to quantify Gambierdiscus and other toxic benthic dinoflagellates for monitoring purposes.

Harmful Algae, 2022
Collecting methods generally used to determine cell abundances of toxic benthic dinoflagellates (BHAB) use cells dislodged from either macrophytes or artificial substrates.

Development of a quantitative PCR assay for the detection and enumeration of a potentially ciguatoxin-producing dinoflagellate, Gambierdiscus lapillus (Gonyaulacales, Dinophyceae).

PLoS ONE, 2019
Ciguatera fish poisoning (CFP) is an illness contracted through the ingestion of seafood containing ciguatoxins. It is prevalent in tropical regions worldwide, including in Australia. Ciguatoxins are produced by some species of Gambierdiscus.

Ciguatera in the Indian Ocean with Special Insights on the Arabian Sea and Adjacent Gulf and Seas: A Review

Toxins, 2021
The dinoflagellates of the genus Gambierdiscus are found in almost all oceans and seas between the coordinates 35° N and 35° S. Gambierdiscus and Fukuyoa are producers of ciguatoxins (CTXs), which are known to cause foodborne disease associated with ...

High ciguatoxin-producing Gambierdiscus clade (Gonyaulacales, Dinophyceae) as a source of toxins causing ciguatera poisoning.

Science of the Total Environment
Ciguatera Poisoning (CP) is caused by neurotoxins (Ciguatoxins, CTXs) produced by microbial eukaryotes (Gambierdiscus, Fukuyoa: Dinophyceae) that accumulate in seafood and can result in severe human illness. More than 80 % of the world's CP occurs in the

Fukuyoa paulensis gen. et sp. nov., a new genus for the globular species of the dinoflagellate Gambierdiscus (Dinophyceae).

PLoS ONE, 2015
The marine epiphytic dinoflagellate Gambierdiscus is a toxicologically important genus responsible for ciguatera fish poisoning, the principal cause of non-bacterial illness associated with fish consumption.

Using RDNA sequences to define dinoflagellate species.

PLoS ONE, 2022
Dinoflagellate species are traditionally defined using morphological characters, but molecular evidence accumulated over the past several decades indicates many morphologically-based descriptions are inaccurate.

Critical Review and Conceptual and Quantitative Models for the Transfer and Depuration of Ciguatoxins in Fishes

Toxins, 2021
We review and develop conceptual models for the bio-transfer of ciguatoxins in food chains for Platypus Bay and the Great Barrier Reef on the east coast of Australia.

Bioguided fractionation of Gambierdiscus extracts

, 2016
The benthic dinoflagellate Gambierdiscus produces ciguatoxins (CTXs) and maitotoxins (MTXs), the most potent marine toxins known to date. CTXs bio-accumulate and cause Ciguatera Fish Poisoning (CFP). Recently, an increasing number of species has been discovered in this genus, and CFP has been reported from areas previously not considered endemic ...

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

Epibenthic Harmful Marine Dinoflagellates from Fuerteventura (Canary Islands), with Special Reference to the Ciguatoxin-Producing Gambierdiscus

Journal of Marine Science and Engineering, 2020
The relationship between the ciguatoxin-producer benthic dinoflagellate Gambierdiscus and other epibenthic dinoflagellates in the Canary Islands was examined in macrophyte samples obtained from two locations of Fuerteventura Island in September 2016. The
