XMRV and polytropic MLV-related virus have been controversially associated with chronic fatigue syndrome (CFS). Subsequent reports failed to detect XMRV and MLV-related virus in CFS patients, and the previous results have been interpreted as a massive laboratory contamination by mouse DNA sequences.
• Among 12 sequential CFS patients, two were positive for XMRV/MLV sequences.
• In contrast, 40 selected control subjects were negative.
• CSF patients and controls were negative for mitochondrial mouse-specific DNA sequences.
• Do not confirm the high frequency of MLV-related viruses infection in CFS patients,
• But also contrast the widespread laboratory contamination previously suggested.
