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 ...
Biosensors Based on Isothermal DNA Amplification for Bacterial Detection in Food Safety and Environmental Monitoring
(Sensors, 2021-01-16) Aigües Marines i Continentals
The easy and rapid spread of bacterial contamination and the risk it poses to human health makes evident the need for analytical methods alternative to conventional time-consuming laboratory-based ...
Use of anionic polymer-coated magnetic beads to pre-concentrate Ostreid Herpesvirus 1 from seawater: Application to a UV disinfection treatment
(Aquaculture, 2021-02-02) Aigües Marines i Continentals; Aqüicultura
Ostreid Herpesvirus 1 (OsHV-1) represents a serious threat to shellfish aquaculture worldwide. To minimise its impact, early warning systems able to detect the virus in seawater prior to infection of ...
Detecting harmful algal blooms with isothermal molecular strategies
(Trends in Biotechnology, 2019-08-06) Aigües Marines i Continentals
The use of isothermal nucleic acid amplification strategies to detect harmful algal blooms (HABs) is in its infancy. We describe recent advances in these systems and highlight the challenges for the ...
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 ...
Detection of Paralytic Shellfish Toxins in Mussels and Oysters Using the Qualitative Neogen Lateral-Flow Immunoassay: An Interlaboratory Study
(Journal of AOAC International, 2018-03-01) Aigües Marines i Continentals
Paralytic shellfish toxins (PSTs) in bivalve molluscs represent a public health risk and are controlled via compliance with a regulatory limit of 0.8 mg saxitoxin (STX)⋅2HCl equivalents per kilogram of ...
Rapid capture and detection of ostreid herpesvirus-1 from Pacific oyster Crassostrea gigas and seawater using magnetic beads
(PLoS ONE, 2018-10-03) Aigües Marines i Continentals; Aqüicultura
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 ...
Self-assembled monolayer-based immunoassays for okadaic acid detection in seawater as monitoring tools
(Marine Environmental Research, 2017-11-14) Aigües Marines i Continentals; Aqüicultura
Rapid and cost-effective methods to monitor the presence of diarrhetic shellfish poisoning (DSP) toxins in seawater samples in an easy and reliable manner are required to protect human health and avoid ...
A Single-Tube HNB-Based Loop-Mediated Isothermal Amplification for the Robust Detection of the Ostreid herpesvirus 1
(International Journal of Molecular Sciences, 2020-09-09) Aigües Marines i Continentals; Aqüicultura
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 ...
Addressing the analytical challenges for the detection of ciguatoxins using an electrochemical biosensor
(Analytical Chemistry, 2020-03-05) Aigües Marines i Continentals
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 ...
