Abstract
Evidence has accumulated indicating that BK virus, following an inapparent primary infection, persists in the renal organs of normal healthy individuals and reactivates upon immunosuppression. Data to support this hypothesis are presented and suggest that BK virus DNA sequences are present at very low levels in the kidneys of more than 50% of the population and that this persistence is localized in several foci within these organs.

DNA homologous to that of the known papovarius BK was cloned from the high molecular weight DNA of two human tissues: a normal liver and a kidney carcinoma. The clone isolated from human liver consisted of DNA indistinguishable from prototype BK by restriction enzyme analysis that used ten different
The three novel human herpesviruses (HHV) 6, 7, and 8 are predominantly, but not exclusively, lymphotropic. In an attempt to elucidate their neurotropism in vivo, viral DNA sequences present in fresh autopsy cortical brain tissues obtained from 84 consecutive Chinese subjects (mean age, 66.9 years;
Urine specimens from bone marrow transplant (BMT) recipients and from controls were directly tested for BK virus (BKV) DNA sequences by dot hybridization and for BKV antigen by a double-antibody indirect ELISA. A total of 158 specimens from 55 BMT patients (57 collected prior to or at the time of tr
