Addressing the analytical challenges for the detection of ciguatoxins using an electrochemical biosensor
(Analytical Chemistry, 2020-03-05)
The importance of ciguatoxins (CTXs) in seafood safety and their emerging occurrence in locations far away from tropical areas highlight the need for simple and low-cost methods for the sensitive and ...
Colorimetric DNA-based assay for the specific detection and quantification of Ostreopsis cf. ovata and Ostreopsis cf. siamensis in the marine environment
(Harmful Algae, 2019-03-16)
Ostreopsis is a toxic benthic dinoflagellate largely distributed worldwide in tropical and temperate areas. In the Mediterranean Sea, periodic summer blooms have been reported and have become a serious ...
Bioaccessibility of lipophilic and hydrophilic marine biotoxins in seafood: An in vitro digestion approach
(Food and Chemical Toxicology, 2019-04-28)
This study aimed to assess the bioaccessibility of different marine biotoxins in naturally contaminated shellfish and fish gonads using an in vitro digestion methodology. In general, hydrophilic toxins ...
Detection of tetrodotoxins in juvenile pufferfish Lagocephalus sceleratus (Gmelin, 1789) from the North Aegean Sea (Greece) by an electrochemical magnetic bead-based immunosensing tool
(Food Chemistry, 2019-03-29)
Two small Lagocephalus sceleratus juveniles were captured in picarel targeting catches from North Aegean Sea (Greece) in the autumn of 2017. An electrochemical immunosensing tool using magnetic beads ...
Electrochemical genosensor for the direct detection of tailed PCR amplicons incorporating ferrocene labelled dATP
(Biosensors and Bioelectronics, 2019-03-30)
An electrochemical genosensor for the detection and quantification of Karlodinium armiger is presented. The genosensor exploits tailed primers and ferrocene labelled dATP analogue to produce PCR products ...
Detection of Ostreopsis cf. ovata in environmental samples using an electrochemical DNA-based biosensor
(Science of the Total Environment, 2019-06-28)
Ostreopsis cf. ovata is a benthic microalga distributed in tropical and temperate regions worldwide which produces palytoxins (PlTXs). Herein, an electrochemical biosensor for the detection of this toxic ...
Evaluation and sensitivity analysis of diatom DNA metabarcoding for WFD bioassessment of Mediterranean rivers
(Science of The Total Environment, 2020-04-04)
Our study of 164 diatom samples from Catalonia (NE Spain) is the first to evaluate the applicability of DNA metabarcoding, based on high throughput sequencing (HTS) using a 312-bp rbcL marker, for ...
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)
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 ...
Assessment of cytotoxicity in ten strains of Gambierdiscus australes from Macaronesian Islands by neuro-2a cell-based assays
(Journal of Applied Phycology, 2018-06-15)
Within the dinoflagellate genus Gambierdiscus several species are well-known producers of ciguatoxins (CTXs) and maitotoxins (MTXs). These compounds are potent marine toxins that accumulate through the ...
Marine Dinoflagellate Assemblage in the Galápagos Marine Reserve
(Frontiers in Marine Science, 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 ...
