Insights
WU polyomavirus (WUPyV) was detected in Chinese children, confirming its presence in respiratory secretions. This finding contributes to understanding WUPyV
Area of Science:
- Virology
- Molecular Biology
- Pediatrics
Background:
- WU polyomavirus (WUPyV), a novel polyomavirus, is linked to respiratory infections.
- The clinical significance and pathogenicity of WUPyV remain largely unknown.
Purpose of the Study:
- To confirm the presence of WU polyomavirus in a pediatric population in China.
- To identify WUPyV in nasopharyngeal aspirate samples from children.
Main Methods:
- Polymerase Chain Reaction (PCR) was employed for WUPyV detection.
- Nasopharyngeal aspirate specimens from 278 children were analyzed.
- PCR products were directly sequenced for precise identification.
Main Results:
- WU polyomavirus was identified in one out of 278 nasopharyngeal aspirates (0.4% positivity rate).
- Sequencing confirmed the detected WUPyV strains were identical to prototype strains.
- The genome, Large T-antigen (LTAg), and VP2 gene sequences matched reference WUPyV.
Conclusions:
- This study confirms the presence of WU polyomavirus in respiratory secretions in China.
- The findings provide initial evidence of WUPyV circulation in the Chinese pediatric population.
Background:
WU polyomavirus (WUPyV), a new member of the genus of Polyomavirus in the family Polyomaviridae, has been found and associated with respiratory tract infections recently. However, its clinical role and pathogenicity has not been known.
Objectives:
To confirm that WU polyomavirus has been found in Chinese children.
Study Design:
WU polyomavirus was detected and identified using PCR methods. A total of 278 specimens of nasopharyngeal aspirate were collected, and then PCR products were sequenced directly.
Results:
One of 278 nasopharyngeal aspirates was positive for WUPyV in one child, and the positive rate was 0.4%. The results showed that the sequences of genome, LTAg and VP2 gene was identical to the reference sequences of WU polyomavirus prototype strains.
Conclusions:
We confirmed that WU polyomavirus had been found and identified in the respiratory secretions in China.
