Video of March 2 XMRV-Related Presentations at Conference on Retroviruses and Opportunistic Infections

The 18th Conference on Retroviruses and Opportunistic Infections (CROI 2011), held in Boston the week of Feb 27 through Mar 2, included presentations on XMRV and chronic fatigue syndrome.

A video released Mar 3 includes nine brief research presentations “XMRV: New Findings and Controversies,” plus a brief recap of key findings and, finally, an audience Q&A. The video is provided here: (Give video time to load)

Among the questions raised: Is it likely that XMRV evolved in the lab from some virus combination that resulted in infected cell lines, and regardless of its origins, are lab staff who have worked with these cells becoming infected, and what diseases might be associated with XMRV?

A summary by CFIDS Assoc. Scientific Director Suzanne Vernon, PhD, is very useful given to the technical language used in the presentations – See
