The toxin is the protein botulinum toxin produced under anaerobic conditions (where there is no oxygen) [38] by the bacterium Clostridium botulinum. [39] Clostridium botulinum is a large anaerobic Gram-positive bacillus that forms subterminal endospores. [40] There are eight serological varieties of the bacterium denoted by the letters A to H.
Botulinum toxin can cause botulism, a severe flaccid paralytic disease in humans and other animals, [3] and is the most potent toxin known to science, natural or synthetic, with a lethal dose of 1.3–2.1 ng/kg in humans. [4] [5]
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 ]
Clostridium botulinum; Note: Botulism is not an infection by Clostridium botulinum but caused by the intake of botulinum toxin. Botulism (and Infant botulism) Enzyme-linked immunosorbent assays (ELISAs), electrochemiluminescent (ECL) tests Botulism antitoxin and supportive care No Sabiá virus: Brazilian hemorrhagic fever: No Brucella species ...
Clostridium species are readily found inhabiting soils and intestinal tracts. Clostridium species are also a normal inhabitant of the healthy lower reproductive tract of females. [14] The main species responsible for disease in humans are: [15] Clostridium botulinum can produce botulinum toxin in food or wounds and can cause botulism.
Clostridium perfringens is an anaerobic, gram-positive bacteria that is often found in the large and small intestines of humans and other animals. Clostridium perfringens has the ability to reproduce quickly producing toxins relating to the cause of diseases.
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.
