Abstract:
We, for the first time, have carried out a search for tetrodotoxin and its analogues (TTXs) in extracts of various animals being potential diet items for highly toxic nemerteans Cephalothrix cf. simula using high-performance liquid chromatography with tandem mass spectrometry (HPLC-MS/MS). We have screened TTXs in a total of 57 specimens from 2 classes. Рresence of TTX from five polychaetes species belonging to three families was shown. We here discuss the role of diet items as a source of TTXs for carnivorous TTX-bearing animals.

Toxic Reactions: Overview
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...
