BK Polyomavirus and Transformation [PDF]
American Journal of Transplantation, 2011 The human BK polyomavirus (PyV) (BKV) was isolated from the urine of a kidney transplant patient with the initials B.K. after cells with nuclear atypia were noted in the urine in the diagnostic workup of an alloureter stenosis. Electron microscopy revealed intranuclear inclusions of nonenveloped viral particles of 40–45-nm diameter suggesting infection

Cytomegalovirus and polyomavirus BK posttransplant [PDF]
Nephrology Dialysis Transplantation, 2007 Virus replication and progression to disease in transplant patients is determined by patient-, graft- and virus-specific factors. This complex interaction is modulated by the net state of immunosuppression and its impact on virus-specific cellular immunity.

Role of BK human polyomavirus in cancer [PDF]
Infectious Agents and Cancer, 2018 Human polyomaviruses (HPyV), which are small DNA viruses classified into the polyomaviridae family, are widely distributed in human populations. Thirteen distinct HPyVs have been described to date. Some of these viruses have been found in human tumors, suggesting an etiological relationship with cancer.

BK Polyomavirus in Solid Organ Transplantation [PDF]
American Journal of Transplantation, 2013 The human BK polyomavirus (BKV) is the major cause of polyomavirus-associated nephropathy (PyVAN) putting 1-15% of kidney transplant patients at risk of premature allograft failure, but is less common in other solid organ transplants. Because effective antiviral therapies are lacking, screening kidney transplant patients for BKV replication in urine ...

A Case Control Study Reveals that Polyomaviruria Is Significantly Associated with Interstitial Cystitis and Vesical Ulceration. [PDF]
PLoS ONE, 2015 To investigate whether polyomaviruses contribute to interstitial cystitis pathogenesis.A prospective study was performed with 50 interstitial cystitis cases compared with 50 age-matched, disease-free controls for the frequency of polyomaviruria ...

Complete genome sequence of BK polyomavirus subtype Ib-1 detected in a kidney transplant patient with BK viremia using shotgun sequencing [PDF]
, 2017 We report here the complete genome sequence of polyomavirus BK subtype Ib-1, isolate AR11, identified in urine from a human kidney transplant recipient with a clinical diagnosis of BK viremia. The AR11 isolate is closely related to reference strain human

Phylogenetic Analysis of Polyomavirus BK Sequences [PDF]
Journal of Virology, 2006 ABSTRACT Polyomavirus BK (BKV) has emerged as an important pathogen in kidney transplant patients. Existing taxonomic classifications of BKV come from conventional DNA sequence alignments based on limited data derived from the VP1 gene. We have used a phylogenetic whole-genome approach to examine the pattern of diversity and evolutionary ...

Optimized amplification of BK polyomavirus in urine
Journal of Virological Methods, 2022 BK polyomavirus (BKPyV) is a ubiquitous pathogen that typically results in asymptomatic infection. However, in immunocompromised individuals, BKPyV viral shedding in the urine can reach 109 copies per mL. These high viral levels within urine provide ideal samples for next-generation sequencing to accurately determine BKPyV genotype and identify ...

The complete genome sequence BK polyomavirus study in kidney transplanted patients [PDF]
Journal of Nephropathology, 2019 Background: BK polyomavirus is a member of the Polyomaviridae. This virus has spread worldwide and up to 82% of the world populations are serologically positive. BK polyomavirus usually transmits through inhalation or fecal-oral way in childhood, as well
