A fast magnetic bead-based colorimetric immunoassay for the detection of tetrodotoxins in shellfish
(Food and Chemical Toxicology, 2020-04-05)Tetrodotoxin (TTX) is a potent neurotoxin responsible for many food poisoning incidents and some fatalities. Although mainly associated with the consumption of pufferfish, in recent years, TTX has been ... -
A mycobacterial disease is associated with the silent mass mortality of the pen shell Pinna nobilis along the Tyrrhenian coastline of Italy
(Scientific Reports, 2019-02-25)Disease is an increasing threat for marine bivalves worldwide. Recently, a mass mortality event (MME) impacting the bivalve Pinna nobilis was detected across a wide geographical area of the Spanish ... -
A polyphasic approach to the study of the genus Nitzschia (Bacillariophyta): three new planktonic species from the Adriatic Sea
(Journal of Phycology, 2020-10-21)The paraphyletic diatom genus Nitzschia comprises over 1000 morphologically distinct pennate taxa, known from the benthos and plankton of freshwater, brackish and marine environments. The principal ... -
A rapid cleaning method for diatoms
(Diatom Research, 2019-07-18)We describe here a protocol for cleaning diatoms when time is short and the amount of sample is very limited. Essentially, the method consists of drying material onto coverslips and cleaning it directly ... -
A Roadmap for Hazard Monitoring and Risk Assessment of Marine Biotoxins on the Basis of Chemical and Biological Test Systems
(ALTEX - Alternatives to Animal Experimentation, 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 ... -
A smartphone-controlled amperometric immunosensor for the detection of Pacific ciguatoxins in fish
(Food Chemistry, 2021-12-02)Ciguatoxins (CTXs) are marine neurotoxins produced by microalgae of the genera Gambierdiscus and Fukuyoa. CTXs may reach humans through food webs and cause ciguatera fish poisoning (CFP). An immunosensor ... -
A strategy for successful integration of DNA-based methods in aquatic monitoring
(Metabarcoding and Metagenomics, 2022-07-20)Recent advances in molecular biomonitoring open new horizons for aquatic ecosystem assessment. Rapid and cost-effective methods based on organismal DNA or environmental DNA (eDNA) now offer the opportunity ... -
A widespread picornavirus affects the hemocytes of the noble pen shell (Pinna nobilis), leading to its immunosuppression
(Frontiers in Veterinary Science, 2023-12-13)Introduction: The widespread mass mortality of the noble pen shell (Pinna nobilis) has occurred in several Mediterranean countries in the past 7 years. Single-stranded RNA viruses affecting immune cells ... -
Adaptation of the European Fish Index (EFI+) to Include the Alien Fish Pressure
(Fishes, 2023-12-29)The European Fish Index EFI+ is the only fish-based multimetric index for the assessment of the ecological status of running waters that is validated and thus applicable across most countries of the ... -
Adult spawning and early larval development of the endangered bivalve Pinna nobilis
(Aquaculture, 2017-10-16)The development of aquaculture activities has posed an alternative solution for the preservation of some overexploited shellfish fisheries worldwide. In the same way, endemic Mediterranean bivalves such ... -
Age and growth of the endangered fan mussel Pinna nobilis in the western Mediterranean Sea
(Marine Environmental Research, 2019-09-28)The present work, which is the first comparative study of the growth of the fan mussel Pinna nobilis in the western Mediterranean, encompasses 12 populations of this species living in different environments ... -
Agricultural impacts on streams near Nitrate Vulnerable Zones: A case study in the Ebro basin, Northern Spain
(PLoS ONE, 2019-11-08)Agricultural intensification during the last century has caused river degradation across Europe. From the wide range of stressors derived from agricultural activities that impact rivers, diffuse ... -
Alternative Methods for the Detection of Emerging Marine Toxins: Biosensors, Biochemical Assays and Cell-Based Assays
(Marine Drugs, 2014-11-26)The emergence of marine toxins in water and seafood may have a considerable impact on public health. Although the tendency in Europe is to consolidate, when possible, official reference methods based ... -
Amplified plasmonic and microfluidic setup for DNA monitoring
(Microchimica Acta, 2021-09-07)Plasmonic nanosensors for label-free detection of DNA require excellent sensing resolution, which is crucial when monitoring short DNA sequences, as these induce tiny peak shifts, compared to large ... -
