An investigation into ciguatoxin bioaccumulation in sharks

Toxicon, 2016
Ciguatoxins (CTXs) produced by benthic Gambierdiscus dinoflagellates, readily biotransform and bioaccumulate in food chains ultimately bioconcentrating in high-order, carnivorous marine species. Certain shark species, often feeding at, or near the top of the food-chain have the ability to bioaccumulate a suite of toxins, from both anthropogenic and ...

Multiple ciguatoxins in the flesh of fish

Toxicon, 1992
Most cases of ciguatera (fish poisoning) result from consumption of the flesh of fishes contaminated with ciguatoxin(s); however, the relatively low toxicity of ciguateric fish flesh has hindered attempts to identify these ciguatoxin(s). Utilising high performance liquid chromatography, mass spectroscopy and mouse bioassay signs we have determined that

Isolation and characterisation of Indian Ocean ciguatoxin

Toxicon, 2002
We report the isolation and initial characterisation of Indian Ocean ciguatoxin (I-CTX) present in toxic lipid soluble extracts isolated from ciguateric fishes collected off the Republic of Mauritius in the Indian Ocean. Following i.p. injection of this extract, mice displayed symptoms that were similar, though not identical, to those produced by ...

Caribbean Ciguatoxin-1 stability under strongly acidic conditions: Characterisation of a new C-CTX1 methoxy congener

Food Additives and Contaminants Part A-chemistry Analysis Control Exposure & Risk Assessment, 2019
The recent emergence of ciguatera in the eastern Atlantic, particularly in the Canary Islands (Spain) and Madeira (Portugal) prompted the development and implementation of liquid chromatography tandem–mass spectrometry (LC/MS-MS) methods for the ...

[Ciguatoxin and edible reef fishes].

Bulletin de la Societe de pathologie exotique et de ses filiales, 1976
Referring to the various human and animal clinical response to consumption of reef fish, the authors precise the importance of ingested dose and the role of cumulative effects. They point out the arbitrary character of distinguishing poisonous and edible fish of the same species. At the light of these data they find ciguatoxin in edible fish from known

Preliminary results towards ciguatoxin immunodetection.

Bulletin de la Societe de pathologie exotique (1990), 1993
Due to the lack of purified ciguatoxin (CTX), monensin was used as a model for developing an enzyme immunoassay to detect CTX. Specific antibodies directed against monensin have been produced in rabbits and mice using a monensin-protein immunogen obtained in bulk quantities.
