Background: Primary infection with BK virus (BKV) is occurred during childhood and usually asymptomatic, but after initial infection, BKV may persist lifelong in the kidney and genitourinary tract. Reactivation may occur in individuals with compromised immunity such as renal transplant recipients. Due to the role of BKV in BK virus-associated nephropathy (BKVAN) and po...

Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...

JC and BK human polyomaviruses (family Polyomaviridae) may cause severe neurological or urinary tract pathologies in immunocompromised hosts. In the present study, we evaluated a new commercially available PCR and microplate colorimetric hybridization assay for the standardized differential detection of JC virus (JCV) and BK virus (BKV) genomes in clinical samples. This JC/BK Consensus test was...

PURPOSE To optimise a polymerase chain reaction (PCR) based DNA sequencing technique for genotyping polyoma virus in clinical specimens obtained from renal transplant patients. MATERIALS AND METHODS A hundred and thirty (106 peripheral blood and 24 urine) clinical specimens collected from renal transplant patients were included in the study for detecting the presence of  DNA of BK virus (BKV)...

background: primary infection with bk virus (bkv) is occurred during childhood and usually asymptomatic, but after initial infection, bkv may persist lifelong in the kidney and genitourinary tract. reactivation may occur in individuals with compromised immunity such as renal transplant recipients. due to the role of bkv in bk virus-associated nephropathy (bkvan) and potentially renal allograft ...

BACKGROUND BK virus reactivation is a significant complication following renal transplantation that can result in graft failure. Reduction of immunosuppression and substitution of leflunomide for mycophenolate mofetil (MMF) has been used to treat this entity. OBJECTIVES To evaluate the use of leflunomide in BK viremia (BKV) and biopsy proven BK nephropathy (BKN) in kidney and kidney-pancreas ...

The BK Virus (BKV) genome is a double-stranded, circular DNA molecule with genetic organization similar to other polyomaviruses, and high homology to JC Virus (JCV) and SV40. The archetypal form of BKV noncoding regulatory region (NCRR) is the infectious form of BKV that replicates in the urothelium and is excreted in the urine. Rearranged forms of the NCRR are found in kidney and other tissues...

BACKGROUND Primary infection with BK virus (BKV) is occurred during childhood and usually asymptomatic, but after initial infection, BKV may persist lifelong in the kidney and genitourinary tract. Reactivation may occur in individuals with compromised immunity such as renal transplant recipients. Due to the role of BKV in BK virus-associated nephropathy (BKVAN) and potentially renal allograft r...

OBJECTIVE Bkv-miR-B1-5p, one of the microRNAs encoded by BK virus, was recently reported to be elevated in the blood among the patients with BK virus nephropathy (BKVN). Urinary exosome was suggested to be a possible source of biomarker for kidney diseases, but it was unknown whether it could contain viral microRNA as well as human microRNAs. The aim of this study was to evaluate whether urinar...
