摘要

The rise of antibiotic-resistant bacteria, termed “superbugs,” presents a formidable challenge to global health. These pathogens, often responsible for persistent nosocomial infections, threaten the effectiveness of conventional antibiotic therapies. This review delves into the potential of bacteriophages, viruses specifically targeting bacteria, as a powerful tool to combat superbugs. We examined the latest developments in genetic engineering that improve the efficacy of bacteriophages, focusing on modifications in host range, lysis mechanisms, and their ability to overcome bacterial defense systems. This review article highlights the CRISPR-Cas system as a promising method for precisely manipulating phage genomes, enabling the development of novel phage therapies with enhanced efficacy and specificity. Furthermore, we discussed developing novel phage-based strategies, such as phage cocktails and phage-antibiotic combinations. We also analyzed the challenges and ethical considerations associated with phage engineering, emphasizing the need for responsible and rigorous research to ensure this technology’s safe and effective deployment to combat the growing threat of antibiotic resistance.
