Detection of human rhinoviruses by reverse transcription strand invasion based amplification method (RT-SIBA)

Area of Science:

• Molecular Biology
• Virology
• Diagnostic Development

Background:

• Rhinovirus (RV) infections cause significant economic burden and necessitate accurate diagnosis to guide treatment and antibiotic use.
• Diagnosing RV is challenging due to its diverse types and similarity to enteroviruses.

Purpose of the Study:

• To develop a rapid nucleic acid test for Rhinovirus detection suitable for both laboratory and near-patient settings.

Main Methods:

• A novel isothermal nucleic acid amplification method, Reverse Transcription Strand Invasion-Based Amplification (RT-SIBA), was developed.
• The RT-SIBA method was evaluated for its ability to detect Rhinovirus in clinical specimens.

Main Results:

• The RT-SIBA assay demonstrated high analytical sensitivity (96%) and specificity (100%) for Rhinovirus detection.
• The assay provided significantly faster results compared to a reference RT-qPCR method.

Conclusions:

• The rapid detection time and portability of the RT-SIBA assay facilitate prompt diagnosis of Rhinovirus infections.
• This improved diagnostic capability can lead to better patient care and management of respiratory illnesses.
