Even it it works, I can't see many patients opting for this treatment:

Clostridium difficile is a particular problem among patients who have been prescribed strong antibiotics as they also wipe out the so-called 'friendly' disease-fighting bacteria in the intestine. Faecal 'transplants', as they are known, are believed to restore the bacteria to levels at which they help the recovery process.

Doctors involved in the trials admit there are "obvious aesthetic problems" in the treatment, which involves patients ingesting a liquidised sample of faeces from a partner or close relative.
