What is unique about Clostridium tetani?
Clostridium tetani is an obligate anaerobic bacteria whose spores produce two distinct toxins—tetanolysin, which causes local tissue destruction, and tetanospasmin, which causes clinical tetanus.
What is the classification of Clostridium tetani?
ClostridiaClostridium tetani / ClassThe Clostridia are a highly polyphyletic class of Bacillota, including Clostridium and other similar genera. They are distinguished from the Bacilli by lacking aerobic respiration. They are obligate anaerobes and oxygen is toxic to them. Wikipedia
What is Clostridium tetani also known as?
Tetanus is an infection caused by bacteria called Clostridium tetani. When these bacteria enter the body, they produce a toxin that causes painful muscle contractions. Another name for tetanus is “lockjaw”.
What are 4 facts about tetanus?
What is tetanus?The tetanus bacteria produce a poison that affects your nerves and brain.Tetanus can happen after a cut, puncture wound, burn, or any injury that lets germs in through your skin.Symptoms begin with strong muscle spasms 1 to 2 weeks after injury.More items...
What are the signs and symptoms of Clostridium tetani?
SymptomsPainful muscle spasms and stiff, immovable muscles (muscle rigidity) in your jaw.Tension of muscles around your lips, sometimes producing a persistent grin.Painful spasms and rigidity in your neck muscles.Difficulty swallowing.Rigid abdominal muscles.
What causes Clostridium tetani?
Tetanus is an infection caused by a bacterium called Clostridium tetani. Spores of tetanus bacteria are everywhere in the environment, including soil, dust, and manure. The spores develop into bacteria when they enter the body. Unlike other vaccine-preventable diseases, tetanus is not spread from person to person.
Where is Clostridium tetani found in the body?
The bacterium clostridium tetani usually enters the body through an open wound. Tetanus bacteria live in soil and manure. It can also be found in the human intestine and other places.
What is the most common cause of tetanus?
Tetanus is caused by the Clostridium tetani bacterium. Clostridium tetani spores are able to survive for a long time outside of the body. They are most commonly found in animal manure and contaminated soil, but may exist virtually anywhere.
Where can Clostridium tetani be found?
Clostridium tetani is an obligate anaerobic Gram-positive bacillus. The tetanus bacillus forms spores that can be found in soil and house dust, and in animal and human faeces. The spores remain viable for years in the environment and are resistant to boiling and freezing.
How does tetanus spread in the body?
Tetanus is different from other vaccine-preventable diseases because it does not spread from person to person. The bacteria are usually found in soil, dust, and manure and enter the body through breaks in the skin — usually cuts or puncture wounds caused by contaminated objects.
What type of pathogen causes tetanus?
Tetanus is a bacterial infection caused by Clostridium tetani . The bacteria make a toxin in your body that causes the disease. Tetanus causes severe muscle spasms, especially in the neck and jaw (called lockjaw).
Who is most at risk for tetanus?
Risk groups The risk of death from tetanus is highest among people 60 years of age or older. Diabetes, a history of immunosuppression, and intravenous drug use may be risk factors for tetanus. From 2000 through 2019, persons with diabetes were associated with 14% of all reported tetanus cases.

Pathophysiology
- Clostridium tetani is an anaerobic, Gram-positive, spore-forming rod. The spores are highly resilient, which explains their ubiquity, and can easily contaminate wounds, especially those associated with soil contamination. Once inoculated into a suitable anaerobic environment, the spores germinate to produce vegetative bacteria which release the neu...

Overview
Characteristics
Clostridium tetani is a rod-shaped, Gram-positive bacterium, typically up to 0.5 μm wide and 2.5 μm long. It is motile by way of various flagella that surround its body. C. tetani cannot grow in the presence of oxygen. It grows best at temperatures ranging from 33 to 37°C.
Upon exposure to various conditions, C. tetani can shed its flagella and form a
