Combined effects of a simulated marine heatwave and an algal toxin on a tropical marine aquaculture fish cobia (Rachycentron canadum)

Aquaculture Research, Volume 51, Issue 6, Page 2535-2544, June 2020., 2020
Abstract Ongoing global warming is one of the major challenges for the development of aquaculture in the tropical regions where species are already cultured in the water temperature close to their upper physiological thresholds. Furthermore, warming can trigger blooms of toxic algae, yet we do not know how extreme warming such as a marine heatwave (MHW)

Dihydrodinophysistoxin-1 Produced by Dinophysis norvegica in the Gulf of Maine, USA and Its Accumulation in Shellfish

Toxins, 2020
Dihydrodinophysistoxin-1 (dihydro-DTX1, (M-H)−m/z 819.5), described previously from a marine sponge but never identified as to its biological source or described in shellfish, was detected in multiple species of commercial shellfish collected from the ...

In Vitro Interactions between Okadaic Acid and Rat Gut Microbiome

Marine Drugs, 2022
Okadaic acid (OA) is a marine biotoxin associated with diarrhetic shellfish poisoning (DSP), posing some threat to human beings. The oral toxicity of OA is complex, and the mechanism of toxicity is not clear. The interaction between OA and gut microbiota

Confirmation of okadaic acid, dinophysistoxin-1 and dinophysistoxin-2 in shellfish as their anthrylmethyl derivates using UV radiation.

, 2005
A rapid and simple method for confirmation of diarrhetic shellfish poison (DSP) : okadaik acid (OA), dinophysistoxin-1 (DTX-1) and dinophysistoxin-2 (DTX-2) using fluorescence detection following derivatization with 9-Chloromethylanthracene, has been ...

A Structural Basis for the Reduced Toxicity of Dinophysistoxin-2

, 2016
Okadaic acid (OA), dinophysistoxin-1 (DTX-1), and dinophysistoxin-2 (DTX-2) are algal toxins that can accumulate in shellfish and cause diarrhetic shellfish poisoning.

Mass Spectral Characterisation of Three New Groups of Algal Toxins [PDF]

, 2009
This thesis reports the mass spectral identification and characterisation of three new groups of algal compounds. A series of novel pectenotoxins (PTXs) were identified in retained sub-samples of Irish mussel extracts that had previously been utilised ...

Selection and application of aptamers with high-affinity and high-specificity against dinophysistoxin-1

RSC Advances, 2020
For the first time, the aptamer of dinophysistoxin-1 was successfully obtained with high affinity and specificity by SELEX, and an aptasensor with a detection range from 40 to 600 nM was developed by biolayer interferometry.

Safety of oil from Schizochytrium sp. A2 for use in infant and follow‐on formula as a novel food pursuant to regulation (EU) 2015/2283

EFSA Journal, Volume 24, Issue 5, May 2026.
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the safety of an oil derived from the microalga‐like organism Schizochytrium sp. A2 as a novel food (NF) pursuant to Regulation (EU) 2015/2283.

First evidence of Okadaic acid acyl-derivative and Dinophysistoxin-3 in mussel samples collected in Chiloe Island, Southern Chile [PDF]

, 2010
This paper shows the detection of Diarrhetic Shellfish Poison (DSP) phycotoxins, using HPLC-FLD with pre-column derivatization procedure and HPLC-MS methods, in the analysis of shell-fish extracts tested positive with the official DSP mouse bioassay. The
