I just received this email fromthe CFIDS Association of America. While it is not good news, there may be some methodological differences between the UK study and the WPI, et. al. study which MAY account for the differences. I guess time will tell. Dr. Vernon's analysis of the UK study is informative. New XMRV Study Published: Analysis Posted to the Association's Website A study testing for evidence of XMRV infection in CFS patients in the United Kingdom has reported negative results. This is the first publication following the article in the top-ranked journal Science from researchers at the Whittemore Peterson Institute, the National Cancer Institute and Cleveland Clinic that garnered worldwide attention from the media and scientific community. The new report, published Jan. 6, 2010, in the open access online journal PLoS ONE, failed to detect XMRV in CFS, but should not be considered a valid attempt to replicate the findings described by Lombardi et al., in the Oct. 8, 2009 Science article.
