| − | A '''toxin''' is, quite often, a naturally occurring byproduct of many bacterial species that causes harm too living tissue, through interference with basic cell mechanisms, leading to cell death, and if unchecked, massive tissue damage, or even death. [[Botulism]] is one such disease caused by bacterial toxins, though recently a method of controlled injectioned of a non-lethal dose has been used to aid in cosmetic surgery, by tighetening, and firming the skin. Even from paralyzing toxins, we can find a useful purpose, and reason for it to be here. | + | A '''toxin''' is quite often a naturally occurring byproduct of many [[bacteria]]l species, which, when it interacts with living tissue, will often cause harm through interference with basic cell mechanisms, leading to cell death, and eventually, if the bacterial growth is not checked, massive tissue damage, or even death. |
