Klebsiella pneumoniae is a significant threat to global health. At present, the methods of K. pneumoniae detection are culture-based and instrument-dependent and are not suitable for rapid diagnostic. This study reports K. pneumoniae CRISPR-top assay, which can precisely identify K. pneumoniae using nucleic acids of pure cultures or clinical samples in one pot with one fluid-handling step. The K. pneumoniae CRISPR-top reaction can be completed within 60 min at a constant temperature, thus specific instruments are not required. Our results show that CRISPR-top assay yields enormous advantages compared with LAMP detection. The K. pneumoniae CRISPR-top assay can be a high-efficiency alternative tool for rapid and accurate diagnosis of K. pneumoniae infection, especially in resource-limited settings.
