Exploring Bacteriophage Applications in Medicine and Beyond

Bacteriophages, or phages, are microscopic viruses that specifically infect and replicate within bacterial hosts. Their unique ability to target and control bacterial populations makes them valuable tools with applications ranging from human medicine and agriculture and environmental management to biotechnology. In this comprehensive review, we explore the diverse and promising medical and non-medical applications of bacteriophages, highlighting their pivotal role across various niches. From safeguarding food production through pathogen control to their innovative utilization in wastewater treatment, bacteriophages prove to be versatile agents. To achieve applications of phages on a larger scale, it is necessary to make the legal framework more suitable and flexible, create special approval programs (e.g., for novel antimicrobial drugs), and promote targeted research and development activities on phages. Additionally, a more intensive exchange between academia, industry, regulatory authorities, and stakeholders in the health system should be pursued.
