KI and WU polyomaviruses have been detected mainly in specimens from the respiratory tract while Merkel cell polyomavirus has been described in a very high percentage of Merkel cell carcinomas. ❋ Silvia Bofill-Mas (2010)
Here we analyzed the presence and characteristics of newly described human polyomaviruses in urban sewage and river water in order to assess the excretion level and the potential role of water as a route of transmission of these viruses. ❋ Silvia Bofill-Mas (2010)
KI and WU polyomaviruses were identified in 1/8 and 2/8 sewage samples respectively. ❋ Silvia Bofill-Mas (2010)
The procedure developed may constitute a useful tool for studying the excreted strains, prevalence and transmission of these recently described polyomaviruses. ❋ Silvia Bofill-Mas (2010)
Recently, three new polyomaviruses (KI, WU and Merkel cell polyomavirus) have been reported to infect humans. ❋ Silvia Bofill-Mas (2010)
The study of the first 99 suspected cases identified in the French Southern Defence Zone showed that this population (mainly constituting adults 20-60 years old returning from abroad) was infected by a variety of respiratory viruses such as rhinoviruses, pneumoviruses, coronaviruses, enteroviruses, polyomaviruses, and parainfluenza viruses. ❋ Antoine Nougairède Et Al. (2010)
The pandemic influenza virus was found in 15% of cases but rhinoviruses, pneumoviruses, coronaviruses, enteroviruses, polyomaviruses, and parainfluenza viruses could also be identified. ❋ Antoine Nougairède Et Al. (2010)
This study was carried out to determine the prevalence of polyomaviruses including JCV, BKV and SV40 in gastric cancers in Tunisia and to determine the clinicopathological characteristics of virus-associated gastric carcinomas. ❋ Feryel Ksiaa (2010)
The presence of polyomaviruses DNA sequences was surveyed in 61 cases of primary gastric carcinomas and in 53 paired non-tumor gastric mucosa by PCR. ❋ Feryel Ksiaa (2010)
The viruses were concentrated following a methodology previously developed for the detection of JC and BK human polyomaviruses in environmental samples. ❋ Silvia Bofill-Mas (2010)
Seroprevalence of polyomavirus-specific antibodies for McPyV and the other four polyomaviruses-BK, JC, WU, and KI-was also determined in another 451 control subjects, who represented the general population. ❋ Unknown (2009)
Among the 451 control subjects, prevalence of antibodies against the five human polyomaviruses was 92% for BK virus, 45% for JC virus, 98% for WU polyomavirus, 90% for KI polyomavirus, and 59% for MCPyV. ❋ Unknown (2009)
Ph. D., of Fred Hutchinson Cancer Research Center in Seattle, and colleagues investigated the levels of antibodies against all five human polyomaviruses in plasma from 41 patients with Merkel cell carcinoma and 76 matched control subjects. ❋ Unknown (2009)
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 neuroblastomas. ❋ Unknown (2009)
Nonetheless, we suggest that additional data are warranted in tumours of the central and peripheral nervous systems and we do not exclude that other still not yet detected polyomaviruses could be present in these tumours. ❋ Unknown (2009)
While polyomaviruses are normally occurring viruses that harmlessly infect many adults, they can pose serious health problems for individuals who become immunocompromised. ❋ Unknown (2009)
The human polyomaviruses, JC and BK, are responsible for fatal disorders of the brain and kidney, to include progressive multifocal leukoencephalopathy ❋ Unknown (2009)
