It turns out, there probably was a contamination link in the WPI studies documenting evidence of XMRV as a cause of Chronic Fatigue Syndrome (CFS). Subsequent evidence points in that direction. That doesn’t mean all hope is lost in XMRV playing some role in causing CFS or any other illness. Yet it’s highly likely that a true problem existed within the initial research because of contamination in the laboratory studies at WPI.
Our job is to continue to have hope that “science” does its job well. Let’s face it; none of us want erroneous results. None of us want errors to be made that conjure up false findings and anyone being able to ultimately say, “See. I told you Chronic Fatigue Syndrome isn’t real!”
I urge you to read part of the text below and then check out the entire post at Phoenix Rising. The authors have presented this vital CFS information in a straight-forward format that is not difficult to understand:
Contamination has been a constant theme in the research community over the past 9 months. Finding equal or more positive samples in the negative controls suggests contamination has occurred. In this study a genetic analysis of the positive samples indicated that it had occurred in the WPI. The analysis found that the XMRV the WPI picked up was almost identical to that produced by a lab cell line called 22RV1. This suggested the virus the WPI found had never entered a human body; ie was lab contaminant. (At the Ottawa conference Dr. Silverman, produced evidence of contamination in the original study, which resulted in several parts of the original Science paper being retracted, including the PCR results.)
