Serologic Evidence of Frequent Human Infection with WU and KI Polyomaviruses

Emerging Infectious Diseases, 2009
WU polyomavirus (WUPyV) and KI polyomavirus (KIPyV) are novel human polyomaviruses. They were originally identified in human respiratory secretions, but the extent of human infection caused by these viruses has not been described to date.

WU and KI Polyomaviruses in Respiratory Samples from Allogeneic Hematopoietic Cell Transplant Recipients

Emerging Infectious Diseases, 2012
Data are limited regarding 2 new human polyomaviruses, KI polyomavirus (KIPyV) and WU polyomavirus (WUPyV), in immunocompromised patients. We used real-time PCR to test for these and 12 respiratory viruses in 2,732 nasal wash samples collected during the

DNA from KI, WU and Merkel cell polyomaviruses is not detected in childhood central nervous system tumours or neuroblastomas. [PDF]

PLoS ONE, 2009
BACKGROUND: BK and JC polyomaviruses (BKV and JCV) are potentially oncogenic and have in the past inconclusively been associated with tumours of the central nervous system (CNS), while BKV has been hinted, but not confirmed to be associated with ...

No evidence for WU polyomavirus infection in chronic obstructive pulmonary disease

Infectious Agents and Cancer, 2009
Human polyomaviruses are known to cause persistent or latent infections, which are reactivated under immunosuppression. Polyomaviruses have been found to immortalize cell lines and to possess oncogenic properties. Moreover, the recently discovered Merkel

Polyomaviruses KI and WU in Immunocompromised Patients with Respiratory Disease

Emerging Infectious Diseases, 2009
Polyomaviruses KI (KIPyV) and WU (WUPyV) were recently identified, mainly in respiratory specimens from children. Among 200 patients with respiratory disorders admitted to Saint Louis Hospital, Paris, France, KIPyV was detected in 8% and WUPyV in 1 ...

KI and WU Polyomaviruses and CD4+ Cell Counts in HIV-1–infected Patients, Italy

Emerging Infectious Diseases, 2010
To investigate an association between KI and WU polyomavirus (KIPyV and WUPyV) infections and CD4+ cell counts, we tested HIV-1–positive patients and blood donors.

Clinical epidemiology of bocavirus, rhinovirus, two polyomaviruses and four coronaviruses in HIV-infected and HIV-uninfected South African children. [PDF]

PLoS ONE, 2014
BackgroundAdvances in molecular diagnostics have implicated newly-discovered respiratory viruses in the pathogenesis of pneumonia. We aimed to determine the prevalence and clinical characteristics of human bocavirus (hBoV), human rhinovirus (hRV ...

Human Polyomavirus Reactivation: Disease Pathogenesis and Treatment Approaches

Journal of Immunology Research, Volume 2013, Issue 1, 2013., 2013
JC and BK polyomaviruses were discovered over 40 years ago and have become increasingly prevalent causes of morbidity and mortality in a variety of distinct, immunocompromised patient cohorts. The recent discoveries of eight new members of the Polyomaviridae family that are capable of infecting humans suggest that there are more to be discovered and ...

WU Polyomavirus in Patients Infected with HIV or Hepatitis C Virus, Connecticut, USA, 2007

Emerging Infectious Diseases, 2009
WU polyomavirus (WUPyV) was detected in 10 (8.3%) of 121 HIV-positive plasma specimens, 0 (0%) of 120 HIV-negative serum specimens, and 2 (2.5%) of 79 hepatitis C virus (HCV)–positive serum specimens.

Review on the Relationship between Human Polyomaviruses‐Associated Tumors and Host Immune System

Journal of Immunology Research, Volume 2012, Issue 1, 2012., 2012
The polyomaviruses are small DNA viruses that can establish latency in the human host. The name polyomavirus is derived from the Greek roots poly‐, which means “many,” and ‐oma, which means “tumours.” These viruses were originally isolated in mouse (mPyV) and in monkey (SV40).
