A probiotic drink can cut the chance of contracting diarrhoea associated with the hospital bug Clostridium Difficile, researchers claimed yesterday. A study published in the British Medical Journal found that drinking Actimel reduced the chance of people over 50 getting diarrhoea linked to the dangerous hospital bug. The research team, led by Dr Mary Hickson of the Imperial College Faculty of Medicine, predicted that the finding could save the NHS money.
