Botox comes from a bacterium

Botox (botulinum toxin) is produced by the bacterium Clostridium botulinum. Infection with Clostridium botulinum causes a disabling paralytic illness named botulism. Botulism first paralyzes the face, mouth, and throat muscles before spreading to other parts of the body. When breathing is affected, the person can die.

Clostridium botulinum comes in eight serotypes -A, B, C1, C2, D, E, F, and G. Only A and B are used in clinical preparations.
