KI and WU Polyomaviruses: Seroprevalence Study and DNA Prevalence in SARS-CoV-2 RNA Positive and Negative Respiratory Samples

Microorganisms, 2022
The aim of this work was to study the possible co-infection of KI and WU polyomavirus (KIPyV and WUPyV, respectively) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in respiratory samples and to detect the seroprevalence of KIPyV and ...

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.

Isolation and characterization of WUPyV in polarized human airway epithelial cells

BMC Infectious Diseases, 2020
Background Washington University polyomavirus (WUPyV) is a novel human polyomavirus detected in childwith acute respiratory infection in 2007. However, the relationship between WUPyV and respiratory diseases has yet to be established for lacking of a ...

Infrequent detection of KI, WU and MC polyomaviruses in immunosuppressed individuals with or without progressive multifocal leukoencephalopathy. [PDF]

PLoS ONE, 2011
Conflicting prevalence of newly identified KI (KIPyV), WU (WUPyV) and Merkel Cell Carcinoma (MCPyV) polyomaviruses have been reported in progressive multifocal leukoencephalopathy (PML) patient samples, ranging from 0 to 14.3%. We analyzed the prevalence

Metagenomic detection of viruses in aerosol samples from workers in animal slaughterhouses. [PDF]

PLoS ONE, 2013
Published studies have shown that workers in animal slaughterhouses are at a higher risk of lung cancers as compared to the general population. No specific causal agents have been identified, and exposures to several chemicals have been examined and ...

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 ...
