Rapid detection of Nipah virus using the one-pot RPA-CRISPR/Cas13a assay

In this study, we developed an optimized one-pot assay using recombinase polymerase amplification (RPA) coupled to CRISPR/Cas13a for the molecular detection of NiV. The one-pot RPA-CRISPR/Cas13a assay for NiV detection was specific and did not cross-react against other selected (re)-emerging pathogens. The sensitivity of the one-pot RPA-CRISPR/Cas13a assay for NiV detection can detect as little as 103 cp/μL of total synthetic NiV cDNA. The assay was then validated with simulated clinical samples. The results for the one-pot RPA-CRISPR/Cas13a assay could be visualized with either fluorescence or lateral flow strips for convenient clinical or field diagnostics, providing a useful supplement to the gold-standard qRT-PCR assay for detecting NiV detections.PMID:37178792 | DOI:10.1016/j.virusres.2023.199130
