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 sequental 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 mous-specific DNA sequences. These findings do not confirm the high frequency of MLV-related viruses infeciton in CFS patients, but also contrast the widespread laboratory contamination previously suggested.
Xenotropic and polytropic murine leukemia virus-related sequences are not detected in the majority of patients with chronic fatigue syndrome.

Abstract
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 sequental 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 mous-specific DNA sequences. These findings do not confirm the high frequency of MLV-related viruses infeciton in CFS patients, but also contrast the widespread laboratory contamination previously suggested.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
