Physiological mechanisms involved in the contamination and long retention of the amnesic shellfish poisoning toxin, domo...
Domoic acid (DA) is a neurotoxin produced by diatoms of the genus Pseudo- nitzschia and is responsible for Amnesic Shellfish Poisoning (ASP) in humans. The king scallop Pecten maximus is a high valuable resource frequently exposed to Pseudo- nitzschia blooms, and capable of accumulating high amounts of DA, retaining it for months or even a few year...
Harmful algae diversity from a coastal upwelling system detected by high-throughput sequencing
Published in Frontiers in Marine Science
Introduction In recent years, environmental DNA (eDNA) amplicon sequencing has been used to unveil plankton diversity in the field. Nevertheless, molecular methods, such as this, are rarely used in harmful algal bloom (HAB) monitoring programs, which mainly rely on morphological identification by conventional light microscopy. Methods The present s...
On the conditions promoting Pseudo-nitzschia spp. blooms in the eastern English Channel and southern North Sea
This study investigated the drivers of the blooms of Pseudo-nitzschia seriata and Pseudo-nitzschia delicatissima complexes in the eastern English Channel and southern North Sea. Phytoplankton data series acquired from 1992 to 2020 were analyzed with a multivariate statistical approach based on Hutchinson's niche concept. P. seriata and P. delicatis...

Published in Frontiers in Microbiology
Diatoms are one of the most important phytoplankton groups in the world’s oceans. There are responsible for up to 40% of the photosynthetic activity in the Ocean, and they play an important role in the silicon and carbon cycles by decoupling carbon from atmospheric interactions through sinking and export. These processes are strongly influenced by ...
Biosynthesis and Detection of Domoic Acid from Diatom Pseudo-nitzschia: A Review.
Published in Current pharmaceutical biotechnology
The domoic acid (DA) produced by certain species of the marine pennate diatom genus Pseudo-nitzschia is highly neurotoxic and can induce nerve excitability and neurotoxicity by binding with ionotropic glutamate receptors, causing amnesic shellfish poisoning in humans who consume seafood contaminated with DA. In recent years, poisoning of humans cau...
Assessing a model of Pacific Northwest harmful algal bloom transport as a decision-support tool.
Published in Harmful algae
In the Pacific Northwest, blooms of the diatom Pseudo-nitzschia (PN) sometimes produce domoic acid, a neurotoxin that causes amnesic shellfish poisoning, leading to a Harmful Algal Bloom (HAB) event. The Pacific Northwest (PNW) HAB Bulletin project, a partnership between academic, government, and tribal stakeholders, uses a combination of beach and...
Development, calibration, and evaluation of a model of Pseudo-nitzschia and domoic acid production for regional ocean mo...
Published in Harmful algae
Pseudo-nitzschia species are one of the leading causes of harmful algal blooms (HABs) along the western coast of the United States. Approximately half of known Pseudo-nitzschia strains can produce domoic acid (DA), a neurotoxin that can negatively impact wildlife and fisheries and put human life at risk through amnesic shellfish poisoning. Producti...

A Decade of Time Series Sampling Reveals Thermal Variation and Shifts in Pseudo-nitzschia Species Composition That Contr...
Published in Frontiers in Marine Science
In 2016-17, shellfish harvesting closed for the first time in Narragansett Bay, Rhode Island, USA, from domoic acid (DA), a neurotoxin produced by diatoms of the Pseudo-nitzschia genus. Pseudo-nitzschia have occurred frequently for over 60 years in Narragansett Bay’s Long-Term Plankton Time Series (NBPTS), therefore it is surprising that the first ...
