Detecting harmful algal blooms with nucleic acid amplification-based biotechnological tools
(Elsevier, 2020-08-10)
Harmful algal blooms (HABs) represent a growing threat to aquatic ecosystems and humans. Effective HAB management and mitigation efforts strongly rely on the availability of timely and in-situ tools for ...
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 ...
Rapid capture and detection of ostreid herpesvirus-1 from Pacific oyster Crassostrea gigas and seawater using magnetic beads
(Public Library of Science, 2018-10-03)
Ostreid herpesvirus-1 (OsHV-1) has been involved in mass mortality episodes of Pacific oysters Crassostrea gigas throughout the world, causing important economic losses to the aquaculture industry. In ...
Cell immunolocalization of ciguatoxin-like compounds in the benthic dinoflagellate Gambierdiscus australes M. Chinain & M.A. Faust by confocal microscopy
(Elsevier, 2022-11-23)
Dinoflagellates of the genera Gambierdiscus and Fukuyoa are able to produce potent neurotoxins like ciguatoxins (CTXs), which, after biooxidation in fish, are responsible for ciguatera intoxication. An ...
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 ...
Hybrid Antibody–Aptamer Assay for Detection of Tetrodotoxin in Pufferfish
(American Chemical Society, 2021-10-26)
The marine toxin tetrodotoxin (TTX) poses a great risk to public health safety due to its severe paralytic effects after ingestion. Seafood poisoning caused by the consumption of contaminated marine ...
First report of Gambierdiscus in the Western Mediterranean Sea (Balearic Islands)
(IOC - UNESCO, 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 ...
Gambierdiscus and Fukuyoa as potential indicators of ciguatera risk in the Balearic Islands
(Elsevier, 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 ...
Cyclodextrin polymers as passive sampling materials for lipophilic marine toxins in Prorocentrum lima cultures and a Dinophysis sacculus bloom in the NW Mediterranean Sea
(Elsevier, 2021-07-09)
Cyclodextrins, cyclic oligomers that form a conical structure with an internal cavity, are proposed as new and sustainable materials for passive sampling of lipophilic marine toxins. Two applicability ...
A Single-Tube HNB-Based Loop-Mediated Isothermal Amplification for the Robust Detection of the Ostreid herpesvirus 1
(MDPI, 2020-09-09)
The Ostreid herpesvirus 1 species affects shellfish, contributing significantly to high economic losses during production. To counteract the threat related to mortality, there is a need for the development ...
