Fast and clear portable test for detecting swine Japanese encephalitis virus using a combined CRISPR-based method

Updated

Abstract

The novel one-pot detection method can identify as few as two copies of Japanese encephalitis virus nucleic acid within 1 hour.

  • The method combines recombinant enzyme polymerase isothermal amplification with CRISPR/EsCas13d targeting.
  • Visual fluorescence and lateral flow assay results are produced for easy interpretation.
  • The platform demonstrated 100% concordance with real-time PCR results when validated against clinical samples.
  • It shows no cross-reactivity with other pathogens, indicating high specificity.
  • This approach may serve as an effective point-of-care testing solution for Japanese encephalitis detection in remote settings.
