Fighting fire with fire: using infectious agents to treat persistent infection

Area of Science:

• Microbiology
• Infectious Diseases
• Therapeutics

Background:

• Persistent infections cause significant morbidity and mortality, often requiring long-term antimicrobial therapy.
• Chronic infections include viral diseases (e.g., HIV, hepatitis B) and bacterial infections (e.g., prosthetic joint infections).
• Multi-drug resistant organisms complicate the management of chronic bacterial infections.

Purpose of the Study:

• To review the historical development of using infectious agents, specifically bacteriophages, as therapy.
• To analyze the risks and scenarios associated with innovative phage therapy for persistent infections.
• To provide an overview of bacteriophage applications in treating challenging infections.

Main Methods:

• Literature review of historical data and research on bacteriophage therapy.
• Analysis of case studies and clinical outcomes of phage therapy for bacterial infections.
• Examination of the evolution of therapeutic strategies for persistent microbial infections.

Main Results:

• Bacteriophages have shown potential in targeting recalcitrant bacterial infections, including prosthetic joint infections.
• The application of bacteriophages in therapy has a long history with varying degrees of success.
• Understanding the historical context is crucial for evaluating current and future therapeutic applications.

Conclusions:

• Innovative therapies, such as bacteriophage treatment, offer potential alternatives for managing persistent infections.
• Further research and clinical trials are needed to optimize bacteriophage therapy and mitigate risks.
• The historical perspective informs the ongoing development of novel antimicrobial strategies against resistant pathogens.
