ciguatera

 [se″gwah-ta´rah]
a form of fish poisoning, marked by gastrointestinal and neurologic symptoms due to ingestion of tropical or subtropical marine fish such as the barracuda, grouper, or snapper that have ciguatoxin in their tissues.

ci·gua·te·ra

(sē'gwă-tār'ă),
An acute toxic syndrome with predominantly gastrointestinal and neuromuscular features induced by ingestion of the flesh or viscera of various marine fish of the Caribbean and tropic Pacific reefs that contain ciguatoxin. The lipid-soluble, heat-stable toxin is produced by the dinoflagellate Gambierdiscus toxicus, which is epiphytic on red and brown algae. Herbivorous fish foraging on reef algae consume the flagellates and are in turn consumed by carnivorous fish, the toxin becoming increasingly concentrated as it passes up the food chain. Some 400 species of fish have been associated with human intoxication. Symptoms come on 3-12 hours after exposure and include vomiting and diarrhea, myalgia, dysesthesia and paraesthesia of the extremities and perioral region, pruritus, headache, weakness, and diaphoresis. Toxic effects usually resolve spontaneously in about 1 week.

Ciguatoxins are one of the many naturally occurring biotoxins associated with harmful algal blooms (HABs).
Ciguatoxins can accumulate not only in fish that directly eat Gambierdiscus cells, but also in the predators that eat those fish.
Ciguatera fish poisoning (CFP), caused by the ingestion of predatory reef-dwelling fish harboring ciguatoxins is one of the most commonly reported fish-associated marine intoxications.
(15,16) Ciguatoxins can be detected in suspected fish samples by in vitro mouse neuroblastoma assay for nonspecific sodium channel toxins with any positive extracts later confirmed as specific ciguatoxins by liquid chromatography-tandem mass spectrometry.

The chemical structure of YTX is closely related to other ladder-shaped polyethers like ciguatoxin (CTXs), maitotoxin, brevetoxins (PbTXs), and some diarrhetic shellfish toxins (DSTs).
Context:The ciguatoxins and the other fused polycyclic ether natural products are produced by microscopic marine dinoflagellates and are found in a variety of organisms that feed on them as well as animals further up the food chain.
CFP results from consumption of certain large, predatory, tropical reef fish that have bioaccumulated ciguatoxins (CTX).
The potent neurotoxins responsible for ciguatera are predominantly ciguatoxins (Swift and Swift 1993).
The causative toxins of its clinical manifestations are ciguatoxins (7).
