Detection of Gambierdiscus and Fukuyoa single cells using recombinase polymerase amplification combined with a sandwich hybridization assay
(Journal of Applied Phycology, 2021-04-10) Aigües Marines i Continentals; Aqüicultura
Dinoflagellates of the genera Gambierdiscus and Fukuyoa are known to produce several bioactive compounds including the potent neurotoxic ciguatoxins (CTXs) which are able to accumulate in fish and through ...
Accumulation of C-CTX1 in Muscle Tissue of Goldfish (Carassius auratus) by Dietary Experience
(Animals, 2021-01-19) Aigües Marines i Continentals
Ciguatoxins (CTXs) are produced by dinoflagellates usually present in tropical and subtropical waters. These toxins are bioaccumulated and transformed in fish causing ciguatera fish poisoning (CFP) in ...
Predictive score and probability of CTX-like toxicity in fish samples from the official control of ciguatera in the Canary Islands
(Science of the Total Environment, 2019-03-30) Aigües Marines i Continentals
This research identifies factors associated with the contamination by ciguatoxins (CTXs) in a population of fish and proposes a predictive score of the presence of CTX-like toxicity in amberjack samples ...
First report of Gambierdiscus in the Western Mediterranean Sea (Balearic Islands)
(Harmful Algae News, 2018-02) Aigües Marines i Continentals; Aqüicultura
Gambierdiscus (Dinophyceae) species are benthic dinoflagellates living in marine littoral zones of circumtropical areas and have recently been described in temperate waters [1]. Some species are producers ...
Toxicity characterisation of Gambierdiscus species from the Canary Islands
(Toxins, 2020-02-21) Aigües Marines i Continentals
In the last decade, several outbreaks of ciguatera fish poisoning (CFP) have been reported in the Canary Islands (central northeast Atlantic Ocean), confirming ciguatera as an emerging alimentary risk ...
Presence of CTXs in moray eels and dusky groupers in the marine environment of the Canary Islandsds
(Aquatic Toxicology, 2020-01-31) Aigües Marines i Continentals
Local population frequently consumes moray eels and dusky groupers from the Canary Islands. These species are top predators and the interactions between them include predation but also, in some cases, ...
Gambierdiscus and Fukuyoa as potential indicators of ciguatera risk in the Balearic Islands
(Harmful Algae, 2020-10-22) Aigües Marines i Continentals; Aqüicultura
Gambierdiscus and Fukuyoa are genera of toxic dinoflagellates which were mainly considered as endemic to marine intertropical areas, and that are well known as producers of ciguatoxins (CTXs) and ...
An Attempt to Characterize the Ciguatoxin Profile in Seriola fasciata Causing Ciguatera Fish Poisoning in Macaronesia
(Toxins, 2019-04-13) Aigües Marines i Continentals
Ciguatera Fish Poisoning is a worldwide concern caused by the consumption of fish contaminated with ciguatoxins not only in endemic regions in the Pacific Ocean or the Caribbean Sea but also in emerging ...
Use of Mass Spectrometry to Determine the Diversity of Toxins Produced by Gambierdiscus and Fukuyoa Species from Balearic Islands and Crete (Mediterranean Sea) and the Canary Islands (Northeast Atlantic)
(Toxins, 2020-05-07) Aigües Marines i Continentals
Over the last decade, knowledge has significantly increased on the taxonomic identity and distribution of dinoflagellates of the genera Gambierdiscus and Fukuyoa. Additionally, a number of hitherto ...
Rapid detection of ciguatoxins in Gambierdiscus and Fukuyoa with immunosensing tools
(Ecotoxicology and Environmental Safety, 2020-08-05) Aigües Marines i Continentals; Aqüicultura
Consumption of seafood contaminated with ciguatoxins (CTXs) leads to a foodborne disease known as ciguatera. Primary producers of CTXs are epibenthic dinoflagellates of the genera Gambierdiscus and ...
