A citation code consists of a hyperlinked reference within "ref" begin and end codes.
To repeat the citation for other statements, the reference needs to have a names: "Cite error: Closing </ref> missing for <ref> tag C. botulinum is made up of four different groups (I-IV), related by their collective ability to produce the neurotoxin botulinum.[3] Botulinum toxin has seven serotypes (A-G), most of which cause botulism, a neuroparalytic disease that can be fatal. There are several types of botulism, including food-borne, wound, infant, and iatrogenic botulism.[4] Clostridium botulinum is an extremely biologically diverse microorganism, and can exist in a variety of different environments and conditions, especially due its highly heat resistant spores, which create the botulinum toxin. Botulinum neurotoxin is the most potent natural toxin known to science, and despite even very small doses being fatal, it also has several therapeutic applications. Its most common application is in the cosmetics industry, as botulinum toxin is the active ingredient in Botox®.[5] Overall, Clostridium botulinum is a truly unique microbe that has an extraordinary range of applications in our world.
