Most tetanus infections are the result of deep, dirty wounds because the tetanus bacteria thrive in an anaerobic environment, that is, an environment low in oxygen. A deep wound with devitalized tissue, tissue whose blood supply has been cut off or diminished, is an excellent breeding ground for Clostridium tetani. Once established the bacteria produce a neurotoxin that enters the nervous system, causing increasingly intense muscle spasms. Ultimately even the slightest stimulus, a light touch, a soft sound such as the click of the stethoscope as a doctor takes it from his pocket, or a flash of light will cause an intense generalized spasm. Look up tetanus toxin on the Internet.
Superficial wounds are not entirely exempt from contamination. Tetanus has resulted from corneal abrasions and infected umbilical cords.
Thorough washing of any wound however superficial goes a long way in preventing the disease. The tetanus shot you get is actually a toxoid, not a vaccine in the truest sense. It is derived from the tetanus toxin, and produces immunity to the toxin, not to the germ itself. It is probably the most effective immunizing agent of all the available vaccines we have.Source(s): I saw many cases of tetanus early in my career during a short stint in the sub-tropics. Not a pleasant sight.

The following are factors that effect the life process of tetanus:
Spores of the bacteria C. tetani live in the soil and are found around the world. In the spore form, C. tetani may remain inactive in the soil, but it can remain infectious for more than 40 years.
Infection begins when the spores enter the body through an injury or wound. The spores release bacteria that spread and make a poison called tetanospasmin. This poison blocks nerve signals from the spinal cord to the muscles, causing severe muscle spasms. The spasms can be so powerful that they tear the muscles or cause fractures of the spine.
The time between infection and the first sign of symptoms is typically 7 to 21 days. Most cases of tetanus in the United States occur in those who have not been properly vaccinated against the disease.
