A bacterium found in soil is a showing promise as a way of delivering cancer drugs into tumours.
Spores of the Clostridium sporogenes bacterium can grow within tumours because there is no oxygen.
BBC News - Soil bacterium helps kill cancers
A spore is not a bacterium. Spores are tricky...and hard to kill. Though i am interested to see how the research comes out.
Clostridia turns into a spore when conditions are adverse and stays in that stasis environment until it is reintroduced into a favorable environment where it converts back to it's bacterial self.
That's the deal with tetanus. C. tetani inhabits bovine GI tracts. So a cow can drop a load on barb wire fence and a bunch of C. tetani is on the barb wire and reverts to spores. Ten years later, someone steps on the fence and innoculates themselves with C. tetani that turns into the bacteria and starts producing tetanus toxin.
There is a mistaken association with tetanus and rust. It's not the rust. It's the old metal that may or may not have cow feces on it.
