anatoxin

Neurotoxin produced by some cyanobacteria including species of Anabaena, Oscillatoria, Aphanizoomenon. Includes anatoxin-a, a potent nicotinic toxin, which is toxic to a wide range of species, and the cholinesterase inhibitor anatoxin-a(s), which is highly toxic to pigs, dogs and some waterfowl but seems to be unable to reach the brain or the retina in many species. Called also sudden death factor.
