As a major etiological agent of healthcare-associated infections (HAIs), its global prevalence continues to rise, a trend closely linked to the increasing problem of multidrug resistance driven by overuse of antibiotics. Therefore, rapid and accurate detection is essential for timely treatment and improved prognosis.

The Cas12a-crRNA complex specifically recognized the amplification product and triggered nonspecific cleavage of a single-stranded DNA (ssDNA) reporter, generating a fluorescent signal that could be quantified in a real-time PCR system or visualized directly under ultraviolet (UV) light. After optimization of key parameters\u2014including RPA primers, reaction conditions, crRNA sequence, and the crRNA\/Cas12a combination\u2014the assay achieved a limit of detection (LOD) of 10\n                      <jats:sup>\u22122<\/jats:sup>\n                      ng\/\u03bcL within a short turnaround time, and showed no cross-reactivity with other common pathogen detection results from clinical isolates and spiked samples were fully consistent with those obtained through PCR\/qPCR, confirming high reliability. In summary, the RPA-CRISPR\/Cas12a detection method established in this study is sensitive, specific, and reliable. Its simplicity, minimal equipment requirements, and cost-effectiveness make it a promising tool for rapid clinical detection of\n                      <jats:italic toggle=\"yes\">E. faecalis<\/jats:italic>\n                      .\n                    <\/jats:p>\n                    <jats:sec>\n                      <jats:title>IMPORTANCE<\/jats:title>\n                      <jats:p>\n                        <jats:italic toggle=\"yes\">Enterococcus faecalis<\/jats:italic>\n                        is a major opportunistic pathogen responsible for severe healthcare-associated infections, with rising prevalence linked to antibiotic resistance.
