Bacteriophage therapy is a treatment that uses viruses called bacteriophages to target and kill specific bacteria. These viruses infect bacteria, replicating inside them until the bacteria burst, effectively eliminating the infection. This therapy is particularly useful for antibiotic-resistant bacterial infections, where traditional antibiotics may fail. The use of bacteriophages dates back to the early 20th century but has gained renewed interest due to rising antibiotic resistance. Researchers are exploring how to harness these natural viruses in clinical settings, aiming to develop personalized treatments that can adapt to the unique bacterial profiles of individual patients.
