Is tetanus caused by a pathogen?

Yes, tetanus is caused by a pathogen. The pathogen responsible for tetanus is the bacterium *Clostridium tetani*. This bacterium is commonly found in soil, dust, and manure. It can enter the body through a wound, where it releases a powerful neurotoxin called *tetanospasmin*. This toxin affects the nervous system, causing muscle stiffness, spasms, and potentially life-threatening respiratory problems. Vaccination against tetanus is important to prevent infection and avoid the serious complications it can cause.
