Severe food poisoning events after the consumption of sharks have been reported since 1940s; however, there has no clear understanding their cause. Herein, we report for first time presence ciguatoxins (CTXs) in sharks. The identification by mass spectrometry CTXs, including two new analogues, a bull shark (Carcharhinus leucas) that was consumed humans, causing and death 11 people Madagascar 2013 is described. Typical neurotoxic ciguatera symptoms were recorded patients, toxicological assays...
Cyclic imines are lipophilic marine toxins that bioaccumulate in seafood. Their structure comprises a cyclic-imino moiety, responsible for acute neurotoxicity mice. have not been linked yet to human poisonings and regulated Europe, although the European Food Safety Authority requires more data perform conclusive risk assessment consumers. This work presents first detection of pinnatoxin G (PnTX-G) Spain 13-desmethyl spirolide C (SPX-1) shellfish from Catalonia (Spain, NW Mediterranean Sea)....
Tetrodotoxin (TTX) is a potent marine neurotoxin involved in poisoning cases, especially through the consumption of puffer fish. Knowledge toxicity equivalency factors (TEFs) TTX analogues crucial monitoring programs to estimate samples analyzed with instrumental analysis methods. In this work, were isolated from liver Lagocephalus sceleratus individual caught on South Crete coasts. A cell-based assay (CBA) for TTXs was optimized and applied establishment TEFs 5,11-dideoxyTTX,...
Cyst studies carried out in 2002–2003 on Mediterranean Sea sediment from seven different sites along the Catalan and Balearic coasts (Western Mediterranean) revealed a higher diversity of Alexandrium species region than was previously known. The cysts eight toxigenic, marine dinoflagellate genus are described, some, such as A. kutnerae, margalefi, peruvianum pseudogoniaulax, reported area for first time. This is also record resting taylori sediment, description known to date kutnerae...
The ouabain/veratridine-dependent neuroblastoma (neuro-2a) cell-based assay (CBA) was applied for the determination of presence ciguatoxin (CTX)-like compounds in ciguatera-suspected fish samples caught Canary Islands. In order to avoid matrix interferences maximal concentration wet weight tissue exposed neuro-2a cells set at 20 mg equivalent (TE) ml−1 according sample preparation procedure applied. present study, limit quantification (LOQ) CTX1B equivalents extract detection (LOD), being...
The increasing occurrence of puffer fish containing tetrodotoxin (TTX) in the Mediterranean could represent a major food safety risk for European consumers and threaten fishing industry. work presented herein describes development new enzyme linked immunosorbent assay (mELISA) based on immobilization TTX through dithiol monolayers self-assembled maleimide plates, which provides an ordered oriented antigen favors antigen–antibody affinity interaction. mELISA was found to have limit detection...
Tetrodotoxin (TTX) is a marine toxin responsible for many intoxications around the world. Its presence in some pufferfish species and, as recently reported, shellfish, poses serious health concern. Although TTX not routinely monitored, there need fast, sensitive, reliable, and simple methods its detection quantification. In this work, we describe use of an automated patch clamp (APC) system with Neuro-2a cells determination contents samples. The showed IC50 6.4 nM were affected by muscle,...
The frequency and intensity of Pseudo-nitzschia spp. blooms along the coast Catalonia have been increasing over past 20 years. As species from this genus that are documented as toxigenic found in local waters, with both toxic nontoxic cooccurring same bloom, there is a need to develop management tools for discriminating difference. Currently, differentiation requires time-consuming electron microscopy distinguish taxonomic features would allow identification species, cryptic can still remain...
