High prevalence of antibodies against polyomavirus WU, polyomavirus KI, and human bocavirus in German blood donors [PDF]

BMC Infectious Diseases, 2010
Background DNA of the polyomaviruses WU (WUPyV) and KI (KIPyV) and of human bocavirus (HBoV) has been detected with varying frequency in respiratory tract samples of children.

Immunohistochemical detection of KI polyomavirus in lung and spleen. [PDF]

Virology, 2014
Little is known about the tissue tropism of KI polyomavirus (KIPyV), and there are no studies to date describing any specific cell types it infects. The limited knowledge of KIPyV tropism has hindered study of this virus and understanding of its potential pathogenesis in humans.

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

J Clin Virol, 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

WU and KI polyomavirus prevalence in invasive respiratory samples from transplant recipients in Cantabria, Spain. [PDF]

Transplant Proc, 2015
WU and KI polyomaviruses were discovered in 2007 in samples of respiratory secretions of children with acute respiratory symptoms. Seroepidemiologic studies have shown that these viruses are widely distributed throughout the world, but their incidence in Spain has not been determined.

WU and KI polyomavirus infections in pediatric hematology/oncology patients with acute respiratory tract illness. [PDF]

J Clin Virol, 2011
WU and KI polyomaviruses (PyV) were discovered in 2007 in respiratory tract samples in adults and children. Other polyomaviruses (BKPyV and JCPyV) have been associated with illness in immunocompromised patients, and some studies suggest a higher prevalence of WUPyV and KIPyV in this population.To determine whether a higher prevalence or viral load for ...

[A molecular epidemiological study of KI polyomavirus and WU polyomavirus in children with acute respiratory infection in Tianjin, China]. [PDF]

Zhongguo Dang Dai Er Ke Za Zhi, 2017
To investigate the relationship of KI polyomavirus (KIPyV) and WU polyomavirus (WUPyV) with acute respiratory infection in children in Tianjin, China.A total of 3 730 nasopharyngeal secretions were collected from hospitalized children with acute respiratory infection in Tianjin Children's Hospital from January 2011 to December 2013.

Detection of KI polyomavirus and WU polyomavirus DNA by real-time polymerase chain reaction in nasopharyngeal swabs and in normal lung and lung adenocarcinoma tissues. [PDF]

Microbiol Immunol, 2011
Polyomaviruses KI (KIPyV) and WU (WUPyV) were detected from 7 (3.0%) and 38 (16.4%) of 232 children with respiratory tract infections by real-time PCR. The rates of infection by KIPyV and WUPyV alone were 3 of 7 (42.9%) and 20 of 38 (52.6%), respectively.

Identification of the novel KI Polyomavirus in paranasal and lung tissues [PDF]

Journal of Medical Virology, 2009
AbstractKI is a novel polyomavirus identified in the respiratory secretions of children with acute respiratory symptoms. Whether this reflects a causal role of the virus in the human respiratory disease remains to be established. To investigate the presence of KIV in the respiratory tissue, we examined 20 fresh lung cancer specimens and surrounding ...

Newly described human polyomaviruses Merkel Cell, KI and WU are present in urban sewage and may represent potential environmental contaminants

Virology Journal, 2010
Recently, three new polyomaviruses (KI, WU and Merkel cell polyomavirus) have been reported to infect humans. It has also been suggested that lymphotropic polyomavirus, a virus of simian origin, infects humans. KI and WU polyomaviruses have been detected

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
