The Future of Phage: Ethical Challenges of Using Phage Therapy to Treat Bacterial Infections
1University of Pennsylvania.
Abstract:
For over a century, scientists have run experiments using phage viruses to treat bacterial infections. Until recently, the results were inconclusive because the mechanisms viruses use to attack bacteria were poorly understood. With the development of molecular biology, scientists now have a better sense of how phage work, and how they can be used to target infections. As resistance to traditional antibiotics continues to spread around the world, there is a moral imperative to facilitate research into phage therapy as an alternative treatment. This essay reviews ethical questions raised by phage therapy, and discusses regulatory challenges associated with phage research, and phage treatments.
Insights
Phage therapy, using viruses to combat bacterial infections, is gaining traction due to antibiotic resistance. Understanding viral mechanisms is key to developing this alternative treatment.
Area of Science:
- Microbiology
- Virology
- Infectious Diseases
Background:
- Phage therapy has a long history, with early results often inconclusive due to poorly understood viral mechanisms.
- The rise of antibiotic resistance necessitates exploring alternative treatments for bacterial infections.
Purpose of the Study:
- To review the ethical considerations surrounding phage therapy.
- To discuss the regulatory challenges in phage research and treatment.
Main Methods:
- Review of historical and current scientific literature on phage therapy.
- Analysis of ethical frameworks and regulatory landscapes.
Main Results:
