The Rise and Fall of Phage Therapy: A History of Bacterial Virus Treatment

🦠Phage therapy uses bacteriophages to infect and destroy specific bacteria.

🔬Scientists like Ernest Hankin, Fredrick Twort, and Felix d'Herelle played key roles in the early development of phage therapy.

📉Phage therapy faced challenges with specificity, manufacturing risks, and the discovery of bacterial resistance and immune clearance.

💊Phage-based medicines were developed by companies like Eli Lilly but lacked substantial clinical evidence.

🌍Research on phage therapy continues, with ongoing studies exploring its potential.
