To obtain immediate immunity against tetanus, a patient should receive antibodies against tetanus toxin. The toxin is produced by the obligate, anaerobic bacteria called Clostridium tetani, which is commonly found in soil. It enters the body through the open skin, and the toxin enters the central nervous system by traveling along peripheral nerves. Tetanus toxin causes generalized severe muscular spasms and hypertonicity when it blocks the release of inhibitory neurotransmitters at the neuromuscular junction.
