How long can tetanus spores live

Tetanus is a dangerous nerve ailment caused by the toxin of a common bacterium, Clostridium tetani. Bacterial spores are found in soil — most frequently in cultivated soil, least frequently in virgin soil. The spores can remain infectious for more than 40 years in soil.

What kills tetanus spores?

Use of aqueous iodine or 2% glutaraldehyde at pH 7.5 to 8.5 kills spores within 3 hours; autoclaving at 120° C and 15 psi destroys them within 15 to 20 minutes.

How long can tetanus lay dormant?

Does tetanus live on surfaces?

The spores are found everywhere in the environment, particularly in soil, ash, intestinal tracts/feces of animals and humans, and on the surfaces of skin and rusty tools like nails, needles, barbed wire, etc. Being very resistant to heat and most antiseptics, the spores can survive for years.

Can tetanus live in dust?

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.
