Recent Developments in Botulinum Neurotoxins Detection

  • Christine Rasetti-Escargueil and
  • Michel R. Popoff

Botulinum neurotoxins (BoNTs) are produced as protein complexes by bacteria of the genus Clostridium that are Gram-positive, anaerobic and spore forming (Clostridium botulinum, C. butyricum, C. baratii and C. argentinense spp.). BoNTs show a high imm...
