Marine Dinoflagellate Assemblage in the Galápagos Marine Reserve
(Frontiers Media, 2019-05-07)
It is likely that harmful algal blooms have increased in frequency, intensity, and geographic distribution in the last decades in response to anthropogenic activities. The Galápagos Islands are renowned ...
Further Advance of Gambierdiscus Species in the Canary Islands, with the First Report of Gambierdiscus belizeanus
(MDPI, 2020-10-31)
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 ...
An Attempt to Characterize the Ciguatoxin Profile in Seriola fasciata Causing Ciguatera Fish Poisoning in Macaronesia
(MDPI, 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 ...
Identification of ciguatoxins in a shark involved in a fatal food poisoning in the Indian Ocean
(Nature Research, 2017-08-15)
Severe food poisoning events after the consumption of sharks have been reported since the 1940s;
however, there has been no clear understanding of their cause. Herein, we report for the frst time ...
Identification of New CTX Analogues in Fish from the Madeira and Selvagens Archipelagos by Neuro-2a CBA and LC-HRMS
(MDPI, 2022-03-29)
Ciguatera Poisoning (CP) is caused by consumption of fish or invertebrates contaminated with ciguatoxins (CTXs). Presently CP is a public concern in some temperate regions, such as Macaronesia (North-Eastern ...
Ostreopsis cf. ovata and Ostreopsis lenticularis (Dinophyceae: Gonyaulacales) in the Galapagos Marine Reserve
(Consejo Superior de Investigaciones Científicas, 2020-06-15)
The genus of benthic dinoflagellates Ostreopsis is of particular interest because some species negatively impact human health and coastal marine ecosystems. Ostreopsis populations from a remote area, ...
Ciguatoxin-like toxicity distribution in flesh of amberjack (Seriola spp.) and dusky grouper (Epinephelus marginatus)
(Elsevier, 2023-04-10)
Ciguatoxins (CTXs) are marine neurotoxins that cause ciguatera poisoning (CP), mainly through the consumption of fish. The distribution of CTXs in fish is known to be unequal. Studies have shown that ...
Ciguatoxin Detection in Flesh and Liver of Relevant Fish Species from the Canary Islands
(MDPI, 2022-01-09)
The Canary Islands are a ciguatoxin (CTX) hotspot with an established official monitoring for the detection of CTX in fish flesh from the authorised points of first sale. Fish caught by recreational ...
A Roadmap for Hazard Monitoring and Risk Assessment of Marine Biotoxins on the Basis of Chemical and Biological Test Systems
(ALTEX Edition, 2013-11-01)
Aquatic food accounts for over 40% of global animal food products, and the potential contamination with toxins of algal origin – marine biotoxins – poses a health threat for consumers. The gold standards ...
Evaluation of Toxicity Equivalency Factors of Tetrodotoxin Analogues with a Neuro-2a Cell-Based Assay and Application to Puffer Fish from Greece
(MDPI, 2023-07-29)
Tetrodotoxin (TTX) is a potent marine neurotoxin involved in poisoning cases, especially through the consumption of puffer fish. Knowledge of the toxicity equivalency factors (TEFs) of TTX analogues is ...
