Bacteriophage Therapy: Overcoming Antimicrobial Resistance Through Advanced Delivery Methods

Area of Science:

• Microbiology
• Biotechnology
• Materials Science

Background:

• Antibiotic resistance necessitates novel treatments for bacterial infections.
• Bacteriophages (phages) are viruses that infect bacteria and are being revisited for therapeutic use.
• Phage therapy's success hinges on administration route and delivery systems.

Purpose of the Study:

• To critically review the therapeutic potential of bacteriophages.
• To analyze various phage delivery strategies and formulations.
• To identify challenges affecting phage stability and bioavailability.

Main Methods:

• Review of preclinical and clinical data on phage therapies.
• Analysis of different administration routes: oral, intravenous, inhalation, topical, and local.
• Examination of phage formulations: liquid suspensions, immobilized phages in polymers, liposome carriers.

Main Results:

• Various administration routes show potential for phage delivery to infection sites.
• Phage formulations impact stability and bioavailability, influencing therapeutic success.
• Materials engineering integration is crucial for optimizing phage delivery systems.

Conclusions:

• Effective bacteriophage treatment requires optimized delivery strategies and formulations.
• Understanding phage pharmacokinetics is essential for safe and efficacious therapy.
• Addressing challenges in phage stability and bioavailability is key to combating antimicrobial resistance.
