Botulinum and Tetanus Neurotoxins
Annual Review of Biochemistry, 2019 Botulinum neurotoxins (BoNTs) and tetanus neurotoxin (TeNT) are the most potent toxins known and cause botulism and tetanus, respectively. BoNTs are also widely utilized as therapeutic toxins. They contain three functional domains responsible for receptor-binding, membrane translocation, and proteolytic cleavage of host proteins required for synaptic ...

Conjugative Botulinum Neurotoxin-Encoding Plasmids in Clostridium botulinum
PLoS ONE, 2010 Clostridium botulinum produces seven distinct serotypes of botulinum neurotoxins (BoNTs). The genes encoding different subtype neurotoxins of serotypes A, B, F and several dual neurotoxin-producing strains have been shown to reside on plasmids, suggesting that intra- and interspecies transfer of BoNT-encoding plasmids may occur.

Clostridium botulinum is an anaerobic, gram-positive bacterium that secretes an extremely large neurotoxic molecule (900 kDa), which produces food poisoning or botulism. It is now also used in medicine to treat diseases according to Paracelsus's paradigm that the difference between a poison and a drug lies in the dose.

Botulinum toxin is regarded as the most lethal substance known. It is estimated that the human LD50 for inhalation botulism is 1 to 3 nanograms of toxin/kilogram body mass. Although only three cases of inhalational botulism have been described, an understanding of the pathophysiology of food-borne outbreaks, wound botulism, and infant botulism, and ...

Botulinum B Toxin as an Alternative to Botulinum A Toxin
Ophthalmic Plastic & Reconstructive Surgery, 1993Histochemical effects of botulinum B toxin were studied on fibers from longissimus dorsi muscle in Albino rabbits and compared to effects produced by botulinum A toxin. Acetylcholinesterase staining, muscle fiber size analysis, and ATPase staining indicated botulinum B toxin produced a denervation gradient and field similar to that produced by ...
