Abstract
Thedisablingdisorderknownaschronicfatiguesyndromeormyalgicencephalomyelitis(CFS/ME)hasbeenlinkedin two independent studies to infection with xenotropic murine leukemia virus-related virus (XMRV) and polytropic murine leu- kemia virus (pMLV). Although the associations were not confirmed in subsequent studies by other investigators, patients con- tinue to question the consensus of the scientific community in rejecting the validity of the association. Here we report blinded analysis of peripheral blood from a rigorously characterized, geographically diverse population of 147 patients with CFS/ME and 146 healthy subjects by the investigators describing the original association. This analysis reveals no evidence of either XMRV or pMLV infection.
