Two recently published studies suggest that laboratory contamination was the likely cause of previous evidence linking murine viruses to CFS, highlighting the fact that researchers conducting PCR experiments should be extremely cautious about both inherently contaminated commercial reagents and contamination from laboratory manipulation.

Chronix is developing a test based on its circulating DNA detection technology that will be tested in studies of how patients respond to Hemispherx's experimental drug Ampligen.

The findings support a prior study that identified a similar virus in many CFS sufferers. However, it also conflicts with the results of several other studies that failed to detect gene sequences from either virus in CFS patients, raising questions about the PCR methods employed.
