One hundred and seventeen children and 41 teachers in day nurseries were screened for cytomegalovirus (CMV) viruria over a period of one year. Thirty two (27%) children and two (5%) teachers were found to be excreting virus on at least one occasion. Restriction endonuclease typing showed that virus strains isolated from the children were dissimilar, with the exception of those from sibling pair...

Adenoviruses are increasingly recognized pathogens that affect blood and marrow transplant (BMT) recipients. Experiences with 2889 adult BMT recipients were reviewed to study the incidence, clinical spectrum, risk factors for dissemination, response to therapy, and outcome of adenovirus infections. Eight-five patients (3%) were diagnosed by means of culture (n=85) or culture and histopathologic...

We performed a case-control study to determine the association of BK plasma viremia with hemorrhagic cystitis (HC) in hematopoietic cell transplant (HCT) recipients. Thirty cases of HC (14 of which occurred after platelet engraftment with documented BK viruria [BK-HC]) were compared with matched controls. Weekly plasma samples were tested for BK virus DNA by polymerase chain reaction (PCR). BK ...

Polyomavirus BK (BKV)-associated nephropathy causes premature kidney transplant (KT) failure. BKV viruria and viremia are biomarkers of disease progression, but associated risk factors are controversial. A total of 682 KT patients receiving basiliximab, mycophenolic acid (MPA), corticosteroids were randomized 1:1 to cyclosporine (CsA) or tacrolimus (Tac). Risk factors were analyzed in 629 (92.2...

Fluoroquinolones, DNA gyrase inhibitors, display anti-BK properties through inhibition of DNA topoisomerase and polyomavirus-associated large T-antigen helicase (1,2). An in vitro analysis using older fluoroquinolone compounds, nalidixic acid and oxolinic acid, demonstrated that these agents are capable of inhibiting replication of BK virus (BKV) DNA. Another analysis using contemporary fluoroq...
