Botulism is a rare and potentially fatal illness caused by botulinum toxin, which is produced by the bacterium Clostridium botulinum. The disease begins with weakness, blurred vision, feeling tired, and trouble speaking. This may then be followed by weakness of the arms, chest muscles, and legs.
Clostridium botulinum is a gram-positive, [1] rod-shaped, anaerobic, spore-forming, motile bacterium with the ability to produce botulinum toxin, which is a neurotoxin. [ 2 ] [ 3 ] C. botulinum is a diverse group of pathogenic bacteria .
There are different kinds of botulism, but symptoms most often include difficulty swallowing or breathing, muscle weakness, double vision and drooping facial features. The CDC said the illness can ...
Botulinum toxin, or botulinum neurotoxin (commonly called botox), is a neurotoxic protein produced by the bacterium Clostridium botulinum and related species. [24] It prevents the release of the neurotransmitter acetylcholine from axon endings at the neuromuscular junction, thus causing flaccid paralysis. [25] The toxin causes the disease ...
Honey. Raw honey can cause botulism in birds—caused by a hazardous toxin produced by the Clostridium botulinum bacteria, the experts at ABC say. This can lead to extreme sickness, weakness, and ...
Endotoxins most commonly refer to the lipopolysaccharide (LPS) or lipooligosaccharide (LOS) that are in the outer plasma membrane of Gram-negative bacteria. The botulinum toxin, which is primarily produced by Clostridium botulinum and less frequently by other Clostridium species, is the most toxic substance known in the world. [1]
However, the genus does contain some human pathogens (outlined below). The toxins produced by certain members of the genus Clostridium are among the most dangerous known. Examples are tetanus toxin (known as tetanospasmin) produced by C. tetani and botulinum toxin produced by C. botulinum.
This figure shows that exotoxins are secreted by bacterial cells, Clostridium botulinum for example, and are toxic to somatic cells. Somatic cells have antibodies on the cell wall to target exotoxins and bind to them, preventing the invasion of somatic cells. The binding of the exotoxin and antibody forms an antigen-antibody interaction and the ...
