Some poisons are also toxins, which is any poison produced by animals, vegetables or bacterium, such as the bacterial proteins that cause tetanus and botulism. A distinction between the two terms is not always observed, even among scientists. The derivative forms toxic and poisonous are synonymous.
Tetanus is an infection of the nervous system with a type of bacteria that is potentially deadly, called Clostridium tetani (C tetani). Spores of the bacteria C tetani are found in the soil, and in animal feces and mouth (gastrointestinal tract). In the spore form, C tetani can remain inactive in the soil. But it can remain infectious for more than 40 years. You can get tetanus infection when the spores enter your body through an injury or wound. The spores become active bacteria that spread in the body and make a poison called tetanus toxin (also known as tetanospasmin).
