1. Plural of anatoxin; toxins produced by cyanobacteria (blue-green algae) that are less potent than the original toxin, often used in vaccine development.
Usage: technical; microbiology; also called toxoid in some contexts
2. Plural of anatoxin; neurotoxins produced by certain freshwater cyanobacteria that can poison animals and humans.
Usage: environmental science; also called 'Very Fast Death Factor' (VFDF) in some species

Examples

• Anatoxins in contaminated water supplies have caused illness in livestock.
• Researchers studied anatoxins to develop safer vaccines against bacterial infections.
• The bloom of cyanobacteria produced dangerous anatoxins that closed the beach.
• Anatoxins are modified versions of toxins with reduced virulence.
• Water quality tests detected anatoxins from the algal bloom.
