A breakthrough in molecular biology for the twenty-first century is CRISPR/Cas gene editing, which has been used in a variety of fields due to its simplicity, adaptability, and targeting. Given the current global challenge of severe bacterial resistance, difficulties in detecting antimicrobial resistance, and slow development of antimicrobial drugs, CRISPR/Cas gene-editing technology offers a promising avenue for the development of antibacterial treatments. On the one hand, CRISPR/Cas gene editing technology helps advance the study of bacterial functions and serves as a toolbox. For instance, Cas proteins and exogenous repair systems enable efficient and precise gene editing, nCas proteins and deaminase systems facilitate template-free and single base precision editing, dCas proteins and reverse transcriptase allow for repair-free gene editing, and dCas proteins and modified sgRNA enable gene expression level regulation and gene function analysis. On the other hand, its specific gene recognition and targeted DNA cleavage characteristics can be used for pathogen detection, elimination of drug-resistant bacteria and genes, and hold promise as a new strategy for clinical diagnosis and treatment.
