Presence of CTXs in moray eels and dusky groupers in the marine environment of the Canary Islandsds 

Sanchez-Henao, Andres; García-Álvarez, Natalia; Silva Sergent, Freddy; Estévez, Pablo; Gago-Martínez, Ana; Martín, Francisco; Ramos-Sosa, María; Fernández, Antonio; Diogène, Jorge; Real, Fernando (Aquatic Toxicology, 2020-01-31)
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, ...
 

Predictive score and probability of CTX-like toxicity in fish samples from the official control of ciguatera in the Canary Islands 

Sanchez-Henao, J. Andres; García-Álvarez, Natalia; Fernández, Antonio; Saavedra, Pedro; Silva Sergent, Freddy; Padilla, Daniel; Acosta-Hernández, Begoña; Martel Suárez, Manuela; Diogène, Jorge; Real, Fernando (Science of the Total Environment, 2019-03-30)
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) 

Tudó, Àngels; Toldrà, Anna; Andree, Karl B.; Rey, Maria; Fernández-Tejedor, Margarita; Campàs, Mònica; Diogène, Jorge (Harmful Algae News, 2018-02)
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 

Rossignoli, Araceli E.; Tudó, Angels; Bravo, Isabel; Díaz, Patricio A.; Diogène, Jorge; Riobó, Pilar (Toxins, 2020-02-21)
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 ...
 

An Attempt to Characterize the Ciguatoxin Profile in Seriola fasciata Causing Ciguatera Fish Poisoning in Macaronesia 

Estevez, Pablo; Castro, David; Pequeño-Valtierra, Ana; Leao, José M.; Vilariño, Oscar; Diogène, Jorge; Gago-Martínez, Ana (Toxins, 2019-04-13)
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 ...
 

Rapid detection of ciguatoxins in Gambierdiscus and Fukuyoa with immunosensing tools 

Gaiani, G.; Leonardo, S.; Tudó, À.; Toldrà, A.; Rey, M.; Andree, K.B.; Tsumuraya, T.; Hirama, M.; Diogène, J.; O'Sullivan, C.K.; Alcaraz, C.; Campàs, M. (Ecotoxicology and Environmental Safety, 2020-08-05)
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 ...
 

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) 

Estevez, Pablo; Sibat, Manoëlla; Leão-Martins, José Manuel; Tudó, Angels; Rambla-Alegre, Maria; Aligizaki, Katerina; Diogène, Jorge; Gago-Martinez, Ana; Hess, Philipp (Toxins, 2020-05-07)
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 ...
 

Gambierdiscus and Fukuyoa as potential indicators of ciguatera risk in the Balearic Islands 

Tudó, Àngels; Toldrà, Anna; Todolí, Irene; Andree, Karl B.; Fernández-Tejedor, Margarita; Campàs, Mònica; Sureda, Francesc X.; Diogène, Jorge (Harmful Algae, 2020-10-22)
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 ...
 

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