What causes tetanus?

Germs produce toxin: Tetanus is produced by germs that exist as spores (eggs) in the dirt worldwide. The contamination of any open wound by these spores allows them to germinate and multiply. They produce a toxic chemicle that circulates locally or throughout the body to produce the symptoms of tetanus.If vaccinated, your body is protected from this chemical.

A bacterium: Tetanus is caused by a bacterium called clostridium tetani. The bacterium enters the body through a break in the skin, and delivers toxins in the blood. Toxins block nerves at several levels, causing rigidity, muscle contractions and seizures.
