We will present a case of development of such B cell lymphoma in CFS patients. XMRV-infected individuals with both neuroimmune disease and cancer develop an immune response to XMRV.The isolation of infectious XMRV from prostate cancer patients will be shown for the first time. Pathogenic consequences of this infection will be discussed
Conclusion: XMRV, a retrovirus of unknown pathogenic potential, is infectious in humans."
