The application of the CRISPR-Cas system in Pseudomonas aeruginosa infections.

Due to the extensive drug resistance of Pseudomonas aeruginosa (P. aeruginosa), it is still a great clinical challenge. The clustered regularly interspaced short palindromic repeats and associated proteins (CRISPR-Cas) system has become a promising strategy against this pathogen. This review critically evaluates the multifaceted applications of CRISPR-Cas technology in P. aeruginosa, including its role in antimicrobial resistance, diagnostics, genome editing, and emerging therapeutic and vaccine strategies. In addition to conducting a comprehensive analysis of various studies, we also compared the performance and limitations of various CRISPR platforms, and discussed the main technologies and transformation obstacles in this field. Finally, we look forward to the direction of applying these experimental tools to clinical research in the future.
