WU and KI polyomavirus present in the respiratory tract of children, but not in immunocompetent adults

Journal of Clinical Virology, 2008
Recently, two new polyomaviruses (PyV), termed WUPyV and KIPyV, were identified in respiratory tract specimens from children with acute respiratory tract infections (ARTIs). However, their roles in the disease have not been determined.To determine the prevalence of WUPyV and KIPyV in the Chinese population suffering from ARTIs in Beijing, China, and to

Associations between pathogens in the upper respiratory tract of young children: interplay between viruses and bacteria. [PDF]

PLoS ONE, 2012
High rates of potentially pathogenic bacteria and respiratory viruses can be detected in the upper respiratory tract of healthy children. Investigating presence of and associations between these pathogens in healthy individuals is still a rather ...

The temporal pattern and lifestyle associations of respiratory virus infection in a cohort study spanning the first two years of life

BMC Pediatrics, 2022
Background Respiratory virus infection is common in early childhood, and children may be symptomatic or symptom-free. Little is known regarding the association between symptomatic/asymptomatic infection and particular clinical factors such as ...

Detection of KI WU and Merkel cell polyomavirus in respiratory tract of cystic fibrosis patients [PDF]

Clinical Microbiology and Infection, 2015
In the last few years, many reports have confirmed the presence of WU, KI and Merkel cell (MC) polyomaviruses (PyV) in respiratory samples wordwide, but their pathogenic role in patients with underlying conditions such as cystic fibrosis is still debated.

Role of Human Polyomaviruses in Respiratory Tract Disease in Young Children

Emerging Infectious Diseases, 2008
KI virus was detected in respiratory secretions of 8/367 (2.2%) symptomatic and 0/96 asymptomatic children (p = 0.215). WU virus was detected in 26/367 (7.1%) symptomatic and 6/96 (6.3%) asymptomatic children (p = 1.00).

Identification of WU polyomavirus from pediatric patients with acute respiratory infections in Beijing, China [PDF]

Archives of Virology, 2009
A novel polyomavirus (WU virus) has been identified in pediatric patients with acute respiratory tract infections (ARI), but its role as a respiratory pathogen has not yet been demonstrated. To investigate if WU virus is related to acute respiratory infections in infants and children in Beijing, specimens collected from 674 pediatric patients with ARI ...

Detection of WU Polyomavirus in Cerebrospinal Fluid Specimen from a Patient with AIDS and Suspected Progressive Multifocal Leukoencephalopathy

, 2009
Although detection of WU polyomavirus in a CSF specimen from a patient with AIDS could represent an occasional finding, its association with clinical and radiological signs suggestive of PML but with undetectable JC polyomavirus DNA in CSF is intriguing ...

Antibody response to polyomavirus primary infection: high seroprevalence of Merkel cell polyomavirus and lymphoid tissue involvement. [PDF]

, 2018
Human polyomaviruses (HPyVs) asymptomatically infect the human population establishing latency in the host, and their seroprevalence can reach 90% in healthy adults. Few studies have focused on the pediatric population, and there are no reports regarding

Secondary lymphoid tissue as an important site for WU polyomavirus infection in immunocompetent children

Journal of Medical Virology, 2011
AbstractThe polyomaviruses KI and WU (KIPyV and WUPyV) have been identified in respiratory specimens from children with acute respiratory infections, which suggests the respiratory tract as a possible site of infection. However, the persistence of infection in the lymphoid system is unknown.
