Rapid enzyme-linked immunosorbent assay and colloidal gold immunoassay for assessing okadaic acid and its derivatives in shellfish

Food and Agricultural Immunology, 2022
Okadaic acid (OA) and the analogs of dinophysistoxin (DTX) are important members of diarrhetic shellfish poisoning (DSP) toxins. In this study, five OA-specific mAbs (monoclonal antibodies) were developed from five stable cells of hybridoma.

Toxins of Okadaic Acid-Group Increase Malignant Properties in Cells of Colon Cancer

Toxins, 2020
Diarrhetic shellfish poisoning (DSP) is a syndrome caused by the intake of shellfish contaminated with a group of lipophilic and thermostable toxins, which consists of okadaic acid (OA), dinophysistoxin-1 (DTX-1) and dinophysistoxin-2 (DTX-2).

Integrative monitoring strategy for marine and freshwater harmful algal blooms and toxins across the freshwater‐to‐marine continuum

Integrated Environmental Assessment and Management, Volume 19, Issue 3, Page 586-604, May 2023., 2023
Abstract Many coastal states throughout the USA have observed negative effects in marine and estuarine environments caused by cyanotoxins produced in inland waterbodies that were transported downstream or produced in the estuaries. Estuaries and other downstream receiving waters now face the dual risk of impacts from harmful algal blooms (HABs) that ...

Deciphering interactions between the marine dinoflagellate Prorocentrum lima and the fungus Aspergillus pseudoglaucus

Environmental Microbiology, Volume 25, Issue 2, Page 250-267, February 2023., 2023
Abstract The comprehension of microbial interactions is one of the key challenges in marine microbial ecology. This study focused on exploring chemical interactions between the toxic dinoflagellate Prorocentrum lima and a filamentous fungal species, Aspergillus pseudoglaucus, which has been isolated from the microalgal culture.

Evaluation of the shucking of certain species of scallops contaminated with domoic acid with a view to the production of edible parts meeting the safety requirements foreseen in the Union legislation

EFSA Journal, Volume 19, Issue 8, August 2021., 2021
Abstract EFSA was asked by the European Commission to provide information on the levels of domoic acid (DA) in whole scallops that would ensure that levels in edible parts are below the regulatory limit after shucking. This should include five species of scallops.

Evaluation of the shucking of certain species of scallops contaminated with lipophilic toxins with a view to the production of edible parts meeting the safety requirements foreseen in the Union legislation

EFSA Journal, Volume 19, Issue 3, March 2021., 2021
Abstract EFSA was asked by the European Commission to provide information on levels of lipophilic shellfish toxins in whole scallops that would ensure levels in edible parts below the regulatory limits after shucking, i.e. removal of non‐edible parts. This should include the okadaic acid (OA), the azaspiracid (AZA) and the yessotoxin (YTX) groups, and ...

Risk Assessment of Pectenotoxins in New Zealand Bivalve Molluscan Shellfish, 2009–2019

Toxins, 2020
Pectenotoxins (PTXs) are produced by Dinophysis spp., along with okadaic acid, dinophysistoxin 1, and dinophysistoxin 2. The okadaic acid group toxins cause diarrhetic shellfish poisoning (DSP), so are therefore regulated.
