This is an Australian Fecal Transplant study that had a 58-70% response rate for ME/CFS!!! For treating CFS (published oct 2012) http://www.eventscribe.com/2012/acg/ajaxcalls/postersinfo.asp?title=6110 Bacteriotherapy in Chronic Fatigue Syndrome (CFS): A Retrospective Review Conclusion: Bacteriotherapy achieves initial success rate of 70% in CFS and 58% sustained response. This result is favourable when compared with current therapies where fewer than 10% recover fully and a further 10%-20% worsen during follow-up1. Given that manipulation of the colonic microbiota improved CFS symptoms, bacteriotherapy for CFS warrants further investigation. Furthermore, the pathophysiology of CFS could be in part explained by enteric derived toxin-releasing bacteria capable of producing systemic effects.
