This paper introduces ANCA, an artificial nucleic acid circuit utilizing Argonaute (Ago) proteins for one-step, amplification-free, and isothermal detection of antibiotic-resistant bacteria. The ANCA method employs a continuous autocatalytic reaction via Ago protein cross-catalytic cleavage. Successful detection of carbapenemase-producing Klebsiella pneumoniae (CPKP) in various samples (urine, blood, and swabs) is demonstrated, achieving 100% sensitivity and specificity in renal wash specimens. The method shows promise for rapid and accurate CPKP diagnosis, aiding in preventing nosocomial infections.
