Ciguatera toxin

Ciguatera fish poisoning ( CFP ), also known simply as ciguatera, is a foodborne illness caused by eating reef fish whose flesh is contaminated with certain toxins. Such individual fish are said to be ciguatoxic. Symptoms may include diarrhea, vomiting, numbness, itchiness, sensitivity to hot and cold, dizziness, and weakness Ciguatera beschreibt eine Fischvergiftung durch den Genuss sonst ungiftiger Speisefische. ICD10-Code: T61.0 2 Hintergrund. Der Name Ciguatera leitet sich von dem auf Kuba gebräuchlichen Namen cigua für die Schnecke Cittarium pica ab, die anfangs irrtümlich als Ursache der Erkrankung angesehen wurde. 3 Epidemiologi Toxinen gehört das Ciguatoxin. Eine Lebensmittelvergiftung auf Grund von Ciguatoxin nennt man Ciguatera. Wo kommen Ciguatoxin-haltige Fische vor? Ciguatoxin-haltige Fische leben in der Karibik, im Pazifischen und z.T. im Indischen Ozean. Betroffen sind Regionen mit Korallenriffen.

Die Toxine sind der Auslöser der Ciguatera. 2 Chemische Eigenschaften. Ciguatoxine sind fettlösliche Poly-Etherverbindungen von 13 bis 14 Ringen mit Ether-Brückenbindungen in einer sehr stabilen, leiterähnlichen Struktur. Strukturelle Modifikationen befinden sich hauptsächlich an den beiden Enden des Toxinmoleküls und entstehen überwiegend durch Oxidation. Es sind relativ hitzestabile. Seit kurzem wird Ciguatera erfolgreich mit Mannitol IV behandelt. Die übliche Dosis ist ein Gramm Mannitol pro Kilogramm Körpergewicht. Das Medikament wird intravenös durch eine zwanzigprozentige Mannitollösung verabreicht. Man glaubt, dass das Mannitol auf Zellebene wirkt und das Toxin inaktiv macht Ciguatoxin s, von einigen Dinoflagellaten-Arten (Prorocentrum lima, Gambierdiscus toxicus, Amphidinium-, Coolia-, Osteopsis-, Peridinium-Arten; Pyrrhophyceae) gebildetes Toxin, das sich in der Nahrungskette (vor allem in den Gonaden, der Muskulatur und im Verdauungssystem von Fischen) anreichert und beim Menschen eine Krankheit verursacht, die als Ciguatera bezeichnet wird. Diese tritt in tropischen Regionen (vor allem im pazifischen Raum und in der Karibik), nicht aber in Europa. Ciguatoxine (CTX) sind eine Gruppe von ca. zwanzig komplex gebauten, strukturell eng verwandten, hoch neurotoxischen polycyclischen Poly ethern. Sie sind Stoffwechselprodukte von marinen Dinoflagellaten und Mitverursacher der Ciguatera, einer Lebensmittelvergiftung. Das Ciguatoxin steht synonym für Ciguatoxin CTX1B

Ciguatera is a food-borne toxin found in fish that inhabit reefs in tropical and sub-tropical waters.The toxin is found in microscopic organisms that are concentrated as they move through the food chain from smaller fish to larger fish. Although the toxin can also affect fish, many suffer or show no ill effects. It is particularly dangerous because it is colorless, odorless, and is not. The ciguatera toxin is nondetectable as it does not harm the fish and is unrecognizable when consumed, CHCC stated. Unlike other foodborne illnesses, CFP is not transferred from cross-contamination..
