In a paper published Monday by The Proceedings of the National Academy of Sciences, scientists found gene sequences from several MRV-related viruses in blood cells from 32 out of 37 chronic-fatigue patients but only 3 of 44 healthy ones.
The researchers did not find XMRV, the specific retrovirus identified in patients last fall. But by confirming the presence of a cluster of genetically similar viruses, the new study represents a significant advance, experts and advocates say.
