Insights
Human Bocavirus (HBoV) causes respiratory illness in children. This study found HBoV in 7.14% of samples and sequenced positive cases, identifying conserved NS1 and NP1 genes for improved detection.
Area of Science:
- Virology
- Pediatric Infectious Diseases
- Molecular Diagnostics
Background:
- Human Bocavirus (HBoV) is an emerging pathogen linked to respiratory tract infections in infants and children.
- Global surveillance studies have indicated a significant prevalence of HBoV in pediatric populations.
Purpose of the Study:
- To determine the prevalence of HBoV in nasopharyngeal samples from children with respiratory illness.
- To sequence and analyze the complete coding regions of HBoV to identify conserved genetic markers for improved detection.
Main Methods:
- Polymerase Chain Reaction (PCR) was used to detect HBoV in 252 nasopharyngeal aspirates.
- Whole genome sequencing of three positive samples was performed using a novel set of conserved primers.
Main Results:
- HBoV was detected in 7.14% (18/252) of the pediatric samples.
- The NS1 and NP1 genes exhibited high conservation across HBoV strains.
- VP1 and VP2 genes showed significant variability, but variations were independent of geographical origin.
Conclusions:
- The identified conserved regions, particularly NS1 and NP1, can enhance the development of robust HBoV detection methods.
- The complete coding sequences provide valuable data for improving laboratory diagnostics and understanding HBoV molecular epidemiology.
Abstract:
Human Bocavirus (HBoV) is a novel virus which can cause respiratory tract disease in infants or children. Recently, the prevalence of this virus has been studied worldwide. In this study, 18 of 252 (7.14%) nasopharyngeal suctions from infants or children between 1 month and 9 years of age with respiratory tract illness were HBoV-positive by PCR. Three positive samples were selected for sequencing the entire coding sequences using a new conserved set of primers. The results showed that the most conserved regions of HBoV are the NS1 and NP1 genes, whereas VP1 and VP2 showed frequent variations. However, the complete coding sequences showed that the variations did not depend on the origin of virus found. The complete coding sequences determined in this study can resolve the problem of an HBoV detection method, which can be advantageously implemented in laboratory detection.
