Background
Botulinum Toxin is a protein most commonly known for causing the potentially fatal illness botulism. The protein is produced by three species of obligate anaerobe bacterium, primarily Clostridium botulism, but is also produced by Clostridium baratii and Clostridium butyricum [1] [2] [3]. Clostridium botulism is commonly found in soil, marine sediments, and the gut of grazing animals [4] [5] [6] [7] [8] . When exposed to humans through inhalation, ingestion, or surface wounds, the botulinum toxin acts as a neurotoxin.
There are seven forms of the neurotoxin, named A through G, that are structurally similar but create different immune responses. The forms of Botulinum Toxin that most often cause botulism in humans are A, B, and E.
