Clostridium tetani, tetanus: Path of infection
Clostridium tetani, tetanus: pathogen. Tetanus is a disease of the nervous system that is caused by bacteria. The infection happens when Clostridium tetani enters into open wounds or cuts. The bacterium reproduces and excretes toxines (tetanospasmin) that are transported into the brain via the bloodstream or peripheral nerve tracts. There it inhibits muscle-relaxating synapses which causes paralysis or muscle cramps.
