| identification of a third human polyomavirus. | we have previously reported on a system for large-scale molecular virus screening of clinical samples. as part of an effort to systematically search for unrecognized human pathogens, the technology was applied for virus screening of human respiratory tract samples. this resulted in the identification of a previously unknown polyomavirus provisionally named ki polyomavirus. the virus is phylogenetically related to other primate polyomaviruses in the early region of the genome but has very little ... | 2007 | 17287263 |
| a newly reported human polyomavirus, ki virus, is present in the respiratory tract of australian children. | recently, allander and co-workers reported the discovery of a new human polyomavirus, ki virus, in respiratory secretions from patients with acute respiratory tract infection (arti). | 2007 | 17706457 |
| no evidence for an association between infections with wu and ki polyomaviruses and respiratory disease. | wu virus (wuv) and ki polyomavirus (kipyv) are newly discovered related human polyomaviruses detected in respiratory samples. to investigate their potential role in respiratory disease, we determined their frequencies of detection, clinical presentations and epidemiological characteristics among samples referred for diagnostic respiratory virus testing. | 2007 | 17997354 |

| dna from bk virus and jc virus and from ki, wu, and mc polyomaviruses as well as from simian virus 40 is not detected in non-uv-light-associated primary malignant melanomas of mucous membranes. | the single most important causative factor for malignant melanomas of the skin is uv radiation. however, this is not true for melanomas on body surfaces sheltered from the sun; thus, it is important to seek new causative factors of melanoma genesis. human papillomaviruses and gammaherpesviruses are associated with human skin cancer; for example, human papillomavirus types 5 and 8 are associated with epidermodysplasia verruciformis, and human herpesvirus 8 is associated with kaposi's sarcoma. rec ... | 2008 | 18768658 |
| [identification of ki polyomavirus in children with lower respiratory tract infections from zhejiang region of china]. | ki polyomavirus, which was firstly discovered in 2007, is a new human polyomavirus belonging to polyomaviridae and containing circular double-strand genomic dna. this study was based on identification assay of ki polyomavirus reported. total 2293 clinical sputum specimens from children under 3-years-old were collected and screened from wenzhou medical college affiliated wenling hospital, zhejiang province. a ki polyomavirus was detected and identified, the positive rate was 0.04%. the sequences ... | 2008 | 18780637 |
| wu and ki polyomavirus present in the respiratory tract of children, but not in immunocompetent adults. | 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. | 2008 | 18790667 |
| identification of the novel ki polyomavirus in the respiratory tract of an italian patient. | recently, a new human polyomavirus, kiv, was detected in respiratory specimens of patients with acute respiratory tract infection. whether this reflects a causal role of the virus in the respiratory tract is still debated. to investigate the presence of kiv in respiratory samples of italian patients and to determine the degree of similarity with other known polyomaviruses, 222 respiratory specimens collected by general practitioners between 2006 and 2007 were screened. the entire vp1 gene region ... | 2008 | 18814272 |
| identification of the novel ki polyomavirus in paranasal and lung tissues. | ki 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 normal tissue along with one paranasal and one lung biopsy from two transplanted children. kiv-vp1 gene was detected in 9/20 lung cancer patients and 2/2 tra ... | 2009 | 19152420 |
| wu polyomavirus in patients infected with hiv or hepatitis c virus, connecticut, usa, 2007. | 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. ki polyomavirus was not detected in hiv-positive plasma or hcv-positive serum specimens. hiv-infected persons may be susceptible to systemic wupyv infection. | 2009 | 19624928 |
| serologic evidence of frequent human infection with wu and ki polyomaviruses. | 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. to determine the seroepidemiology of wupyv and kipyiv, we used an elisa to screen serum samples from 419 patients at the st. louis children's hospital and barnes-jewish hospital during 2007-2008. the age-stratified deidentified samples were examined for antibod ... | 2009 | 19751580 |
| association of merkel cell polyomavirus-specific antibodies with merkel cell carcinoma. | merkel cell polyomavirus (mcpyv) has been detected in approximately 75% of patients with the rare skin cancer merkel cell carcinoma. we investigated the prevalence of antibodies against mcpyv in the general population and the association between these antibodies and merkel cell carcinoma. | 2009 | 19776382 |
| ki polyomavirus detected in respiratory tract specimens from patients in st. louis, missouri. | studies have reported the presence of ki polyomavirus (kipyv) and wu polyomavirus (wupyv) in respiratory secretions of young patients. so far, evidence has not supported a link between infections with either virus and respiratory tract disease; however, there has not been a large comparison of kipyv-infected patients to age-matched patient groups. | 2010 | 19949359 |
| detection of ki polyomavirus and wu polyomavirus dna by real-time pcr in nasopharyngeal swabs and in normal lung and lung adenocarcinoma tissues. | 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 single infection of kipyv and wupyv were 3 (42.9%) of 7 and 20 (52.6%) of 38, respectively. in other samples, various viruses (human respiratory syncytial virus, human metapneumovirus (hmpv), human rhinovirus, parainfluenza virus 1 and human bocavirus) were detected simultaneously. one case was positive for kipyv and wupyv and also f ... | 2011 | 21545509 |
| wu and ki polyomavirus infections in pediatric hematology/oncology patients with acute respiratory tract illness. | 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. | 2011 | 21705268 |
