[WU polyomavirus and KI polyomavirus detected in specimens from children with acute respiratory tract infection in China].

Objective: To investigate newly identified polyomavirus WUV and WUV and KIPyV are associated with acute respiratory infections in China, tests were developed to detect WUV and KIPyV gene fragments from nasopharyngeal aspirates collected from children with ARI fron Nov. 2006 to Oct. 2007.

Methods: A total of 318 clinical samples were tested for WUV and KIPyV using PCR method. The positive products were sequenced and compared with those in GenBank.

Results: 14 of the 318 Samples were positive (WUV was 2.2%, KIPyV was 2.2%). All of children who were positive for WUV or KIPyV had respiratory illness.

Conclusion: Polyomavirus WU and KIPyV infection may be associated with upper and lower respiratory diseases.
