Clostridium tetani is a gram-positive, motile, obligate anaerobe commonly found in soil and animal feces. C. tetani produces tetanospasmin, a powerful exotoxin that cleaves synaptobrevin II, an important protein component of synaptic vesicles, thus blocking the activity of inhibitory interneurons in the central nervous system. This leads to tetanus in humans, an acute, often fatal disease that is characterized by chronic muscle contraction, especially in the head and neck, which can eventually lead to respiratory failure. C. tetani poses a dangrous threat to humans, so prevention is important. Tetanus Toxoid is a substance that was purified from tetanospasmin in 1890, and it is currently used as a vaccine to to produce active immunity against tetanus or to help boost the immune response to other vaccines.
