Ciguatera toxin inCheilinus rhodochrous(Po'ou wrasse)

摘要

Cheilinus rhodochrous(po'ou, wrasse) was examined by various assays for the presence of toxins associated with ciguatera fish poisoning. These assays were a stick enzyme immunoassay (S#x2010;EIA); and extraction, chromatography on silica gel, and examination of the fractions by stick enzyme immunoassay, mouse toxicity assay, and guinea pig atrial assay. The active toxic principles were found in the 10 (v/v) and 50 (v/v) methanol/chloroform eluates of viscera and flesh, and had characteristics similar to ciguatoxins found in carnivores.
