CRISPR-Cas-assisted phage engineering for personalized antibacterial treatments.

Background: In the age of modern medicine, CRISPR-Cas system-aided phage engineering has emerged as a major game changer for developing personalized antibacterial treatments. Modifying genomic DNA at a specific location leads to the inactivation of target genes, the acquisition of novel genetic features, and the correction of lethal gene mutations. Phages can be modified to precisely detect and control bacteria because of the vast possibilities of CRISPR-Cas-based genetic engineering.

Objectives: The primary objective of this review is to explore the basic principles, mechanisms, limitations, and perspectives of CRISPR-Cas system-aided phage engineering in producing tailored antibacterial therapeutics. Furthermore, this study will address how editing phage genomes using CRISPR-Cas technology allows for precise bacteria targeting, broadening phage host range, and improving infection control tactics.

Content: The arrival of the CRISPR-Cas system has transformed the field of phage engineering and aided in the precise modification of phagе genomes to broaden the phage host range. This novel strategy uses the accuracy of the CRISPR-Cas system to design engineered bacteriophages, giving targeted options for infection control. These recent advancements have the potential to alter the era of modern medicine.
