Abstract
The RPA-CRISPR/Cas12a system achieved a detection limit of 10 copies per reaction for Brucella DNA.
- The integrated system combines recombinase polymerase amplification (RPA) with the CRISPR-Cas12a technique for enhanced detection.
- It demonstrates high sensitivity and excellent specificity in identifying Brucella species.
- The platform shows strong agreement with quantitative PCR results when tested on clinical blood samples.
- Testing revealed improved performance compared to traditional serological methods like the Rose Bengal test (RBT).
- This method may provide a rapid and accurate approach for diagnosing brucellosis.
