New vectors of TTX analogues in the North Atlantic Coast: the edible crabs Afruca tangeri and Carcinus maenas
Tetrodotoxin (TTX) and its analogues are naturally occurring toxins historically responsible for human poisoning fatalities in Eastern Asia. It is typically linked to the consumption of pufferfish and, to a lesser extent, marine gastropods and crabs. In the scope of a comprehensive project to unders...
