Competing Interests

EAK and RHS are inventors on patents licensed to Abbott Laboratories that relate to methods for detection of XMRV. However, results presented in the current report likely reduce the value of such technology, thus mitigating any conflict of interest issues. This interest does not alter the authors' adherence to all PLoS ONE policies on sharing data and materials. RM and ADM have declared that they have no competing interests.
