The current treatment for c-diff as stipulated in the British national formulary (2007) is Oral Vancomycin or Metronidazole the former being the preferred treatment for patients who are severely ill.

Kado et al (2004) studied the use of bifid bacteria-fermented milk or Yakult as treatment for ulcerative colitis and found it to be effective. This treatment aims to restore the balance of good bacteria in the gut. Poutanen & Simor (2004) agree with the effectiveness of pro-biotics in the treatment and prevention of clostridium difficile.

Joyce and Burns (2002) stipulate that recurrence of a c-diff infection affects around 20% of patients.
