Implication

Diagnostic study demonstrates high sensitivity of quantitative TaqMan PCR over standard tests in pediatric respiratory samples, indicating improved detection and subgrouping of RSV.

Key Points

To develop and evaluate a rapid, quantitative TaqMan reverse transcription-PCR assay for simultaneous detection and subgroup differentiation of respiratory syncytial virus A and B.
Designed subgroup-specific primer-probe sets targeting the nucleocapsid protein gene sequences of RSV A and RSV B.
Assessed analytical specificity against viral stocks and evaluated analytical sensitivity calibrated by plaque-forming units (PFU) and viral RNA copy numbers.
Tested clinical utility on 175 nasopharyngeal aspirates from symptomatic children in Hong Kong (winter 2000–2001) in comparison with viral culture and immunofluorescence.
Analytical sensitivity reached 0.023 PFU (two viral RNA copies) for RSV A and 0.018 PFU (nine viral RNA copies) for RSV B, with complete specificity and no cross-reactivity.
TaqMan PCR detected 36 RSV-positive specimens (10 RSV A, 26 RSV B) out of 175 clinical samples, successfully identifying all 21 culture-positive and 32 immunofluorescence-positive cases while diagnosing additional positive samples.
