A strain of harmless bacteria Clostridium sporogenes that live in soil could soon be helping to kill cancer tumors, thanks to researchers from the University of Nottingham in the UK and the University of Maastricht in the Netherlands who are presenting their work at a conference in York, England, this week.
They said they expect to test the strain in cancer patients in 2013, and if successful, hope the method can be combined with additional approaches to win the battle against cancer.
The bacterium when injected into cancer patients grows in solid tumors and releases an enzyme which triggers a separately injected "pro-drug" to kill cancer cells.
