What bacteria does tetanus belong to?

Medically speaking, it is Clostridium tetanus. Clostridium tetanus is widely found in the natural environment. For example, we often come into contact with some waste nails, waste blades, wood thorns on the ground, and wounds contaminated by some dust, feces, and relatively unclean things. Clostridium tetanus may exist in these. If Clostridium tetanus enters the human body, it will produce tetanus toxin. Tetanus toxin can cause tetanus disease, so Clostridium tetani is the pathogen. However, it is tetanus toxin that causes human disease. Tetanus toxin is easy to produce under the condition of ischemia and hypoxia. In the environment of ischemia and hypoxia, it is easy to manifest under the condition of human muscle damage.
