Sublethal exposure of eastern oyster Crassostrea virginica to the goniodomin‐producing dinoflagellate Alexandrium monilatum: Fate of toxins, histopathology, and gene expression

Journal of Aquatic Animal Health, Volume 36, Issue 4, Page 374-394, December 2024.
Abstract Objective The dinoflagellate Alexandrium monilatum forms blooms during summer in tributaries of the lower Chesapeake Bay. Questions persist about the potential for A. monilatum to negatively affect aquatic organisms. Its main toxin, goniodomin A (GDA), a polyketide macrolide, has been shown to have adverse effects on animals, for example ...

Prey morphotype and abundance controls plastid retention and bloom dynamics for a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 69, Issue 11, Page 2732-2747, November 2024.
Abstract Dinophysis is an obligate mixotroph that relies on consumption of the ciliate, Mesodinium rubrum, to grow and form harmful algal blooms (HABs). In this study, blooms of Dinophysis acuminata in two NY, USA, estuaries were studied over the course of 3 yr (2019–2021) using discrete samples and an Imaging FlowCytobot (IFCB) to capture images of ...

Seasonal Early Warning of Impacts of Harmful Algal Blooms on Farmed Shellfish in Coastal Waters of Scotland

Water Resources Research, Volume 60, Issue 10, October 2024.
Abstract Harmful Algal Blooms (HABs) can produce phycotoxins that accumulate in shellfish and subsequently poison aquatic predators and human consumers, potentially causing significant economic impacts to the shellfish aquaculture industry. HAB events are challenging to foresee as they are driven by complex inter‐annual and seasonal changes in physical,

Exploring potentially synthetic genes related to diarrhetic shellfish toxins production in Prorocentrum sp. via comparative transcriptomics

Ecotoxicology and Environmental Safety
Harmful algal blooms (HABs), exacerbated by climate change and environmental disturbances, pose global challenges due to marine toxin contamination, particularly diarrhetic shellfish toxins (DSTs).

Early Genotoxic and Cytotoxic Effects of the Toxic Dinoflagellate Prorocentrum lima in the Mussel Mytilus galloprovincialis

Toxins, 2016
Okadaic acid (OA) and dinophysistoxins (DTXs) are the main toxins responsible for diarrhetic shellfish poisoning (DSP) intoxications during harmful algal blooms (HABs).

Scientific opinion on marine biotoxins in shellfish in the Republic of Croatia

Food Risk Assess Europe, Volume 2, Issue 2, April 2024.
Summary Marine biotoxins are thermostable, mostly non‐protein molecules with different chemical components. According to solubility, they are divided into water‐soluble (hydrophilic) and fat‐soluble (lipophilic). The regulations of the EU and the Republic of Croatia regarding the maximum limits (ML) in live shellfish cover several groups: azaspiracids (

Exposure of Mytilus galloprovencialis to diarrhetic shellfish poisoning toxin: food safety implications [PDF]

, 2019
Throughout the world, toxins produced by algae are responsible for approximately 60000 human food poisonings yearly. Shellfish toxins cause damage to wildlife and have a negative economic impact on recreation, tourism and shellfish industry, being ...

Diarrhetic Shellfish Toxins and Other Lipophilic Toxins of Human Health Concern in Washington State

Marine Drugs, 2013
The illness of three people in 2011 after their ingestion of mussels collected from Sequim Bay State Park, Washington State, USA, demonstrated the need to monitor diarrhetic shellfish toxins (DSTs) in Washington State for the protection of human health ...

Detection of marine biotoxin in plankton net samples from the Bulgarian coast of Black Sea [PDF]

, 2020
Some diatoms and dinoflagellates can produce marine toxins, which can accumulate in, e.g. filter-feeding bivalves, posing a potent treat to seafood consumers. In this study, concentrated net plankton samples were collected from mussel cultivation regions
