What is the pathophysiology of tetanus?
Tetanus is an infectious disease caused by Clostridium tetani bacteria. The active anaerobic bacteria lead to the production of a tetanus toxin, which enters the nervous system via lower motor neurons and travels up to the spinal cord and brain stem.
When do symptoms of tetanus appear?

What is the pathogenicity of tetanus?
Pathogenesis. Tetanus, or lockjaw, is caused by the toxins of C. tetani. All serovars produce the same exotoxin, which is a multiunit protein composed of tetanospasmin, which is neurotoxic, and tetanolysin, which is hemolytic.
Can tetanus go away on its own?
