The Clinical Applications of Bacteriophage Therapy in Addressing Antibiotic Resistance and Drug Development: Review

Abstract

Background: The rise of antibiotic-resistant bacteria poses a significant threat to global health, necessitating innovative therapeutic strategies. Bacteriophages, viruses that specifically target bacteria, have emerged as a promising alternative to conventional antibiotics. This review explores the clinical applications of phage therapy, focusing on their potential in drug development and treatment of resistant infections.

Methods: A comprehensive literature review was conducted, analyzing studies published between 2000 and 2023 that investigated phage therapy's efficacy against multidrug-resistant (MDR) bacteria. Databases such as PubMed, Scopus, and Web of Science were utilized to identify relevant articles, with a focus on clinical trials and case studies demonstrating phage treatment outcomes.

Results: Phage therapy has demonstrated significant effectiveness in treating infections caused by MDR pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant Enterococci (VRE). Clinical studies reported success rates of up to 77% in eradicating targeted bacteria. Additionally, phages have shown promise in biofilm disruption and targeting intracellular infections. The adaptability of phages has also facilitated their use in vaccine development and gene delivery systems, enhancing their therapeutic potential.

Conclusion: Phage therapy represents a revolutionary approach in combating antibiotic-resistant infections, offering specificity and the ability to self-amplify at the infection site. While challenges such as regulatory hurdles and phage stability remain, ongoing research and technological advancements are paving the way for phage-based therapeutics to become integral in modern medicine. Future studies should focus on optimizing phage engineering and delivery methods to maximize clinical efficacy.
