BBC News - Soil bacterium helps kill cancers:
'via Blog this'
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.
UK and Dutch scientists have been able to genetically engineer an enzyme into the bacteria to activate a cancer drug.
Experts said it would be some time before the potential benefits of the work - presented to the Society of Microbiology - were known.
