A Comprehensive Review on Phage Therapy and Phage-Based Drug Development

Area of Science:

• Microbiology and Infectious Diseases
• Biotechnology and Genetic Engineering
• Medical Science

Background:

• The rise of multidrug-resistant (MDR) bacteria necessitates novel therapeutic approaches.
• Bacteriophages (phages), viruses that infect bacteria, present a promising alternative to conventional antibiotics.
• Phage therapy has a historical precedent and is experiencing a modern resurgence.

Purpose of the Study:

• To provide a comprehensive review of phage therapy.
• To explore the historical context and modern revival of phage applications.
• To detail phage mechanisms, applications, and challenges in clinical integration.

Main Methods:

• Literature review of historical and current research on phage therapy.
• Analysis of phage mechanisms of action against bacterial infections, including biofilms and intracellular pathogens.
• Examination of innovative applications and challenges in phage therapy development.

Main Results:

• Phages demonstrate targeted efficacy against MDR bacterial infections.
• Phage applications extend to vaccine development, cancer therapy, and gene delivery.
• Key challenges include phage stability, host immune response, and regulatory hurdles.

Conclusions:

• Phage therapy holds immense potential as a targeted and efficient treatment for bacterial infections.
• Overcoming challenges in stability, immunogenicity, and regulation is crucial for clinical adoption.
• Further research and development are needed to fully integrate phage-based therapies into medical practice.
