Demonstration of Borna disease virus RNA in peripheral blood mononuclear cells derived from Japanese patients with chronic fatigue syndrome.
Nakaya, T, Takahashi, H, Nakamura, Y et al.·FEBS letters·1996
Researchers tested blood cells from 25 Japanese patients with chronic fatigue syndrome (ME/CFS) to see if a virus called Borna disease virus (BDV) was present. They found evidence of BDV in 3 patients' blood cells and antibodies (immune markers) against BDV in 6 patients, suggesting about 32% of their study group may have been exposed to or infected with this virus. This finding raised the possibility that BDV might be connected to ME/CFS in Japanese patients.
