Tetanus

103

What causes tetanus?

Caused by the tetanus toxin which is produced by teens bacillus that lives in intestines of animals and humans. The organisms are exerted in fecal material and persists as spores in the soil, and are prevalent in rural areas and garden soil fertilizer containing manure. A laceration, puncture, or animal bite introduces the bacteria into the body where it thrives without oxygen.
