Doctors are using human poo pumped through a patient's nose as a medicine for a super stomach bug.
The medicine is liquefied, but not treated in any way, and reaches the patient's stomach via a tube.
It restores bacterial balance and kills the bug, says Associate Professor Ian Seppelt, an Australian intensive care doctor and anaesthetist.
So far the treatment, known as faecal transplant, has been tested only on a drug resistant form of the bowel disease caused by the bacterium clostridium difficile.
Antibiotics are unreliable against the superbug, but the transplant is 95 per cent successful, saving patients from constant stomach cramps and chronic diarrhoea.
