Assessment of NS1 gene-specific real time quantitative TaqMan PCR for the detection of Human Bocavirus in respiratory samples

Human Bocaviruses (HBoV) were associated with respiratory diseases. Here, we assessed a TaqMan®-based PCR for the detection of all four HBoV subtype infections with a sensitivity up to 15 copies/reaction. To evaluate this assay on clinical samples, 178 nasopharyngeal aspirate specimens from pediatric cases were analyzed and HBoV genome was detected in 13 out of 178 patients with a viral load range between 1.6 × 103 and 9.4 × 107 copies/ml. These results indicated that this method could be used as an alternative technique for the diagnosis of HBoV infection.
