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 ...

A Protein Phosphatase 2A-Based Assay to Detect Okadaic Acids and Microcystins

Journal of Marine Science and Engineering
Okadaic acids (OAs) are causative agents of diarrhetic shellfish poisoning, produced by the dinoflagellates Dinophysis spp. and Prorocentrum spp. Microcystins (MCs) are cyclic heptapeptide hepatotoxins produced by some cyanobacteria genera, including ...
