Phage therapy, viral phage therapy, or phagotherapy is the therapeutic use of bacteriophages for the treatment of pathogenic bacterial infections. [1] [2] [3] This therapeutic approach emerged at the beginning of the 20th century but was progressively replaced by the use of antibiotics in most parts of the world after the Second World War.
Although phages do not infect humans, there are countless phage particles in the human body, given the extensive human microbiome. One's phage population has been called the human phageome, including the "healthy gut phageome" (HGP) and the "diseased human phageome" (DHP). [107] The active phageome of a healthy human (i.e., actively replicating ...
After positive media attention from Patterson's phage therapy, [9] [10] [11] Schooley and Strathdee began to receive phage therapy requests from around the globe. They were involved in the treatment of five other phage therapy patients at UC San Diego School of Medicine and consulted on numerous cases throughout the United States and Europe ...
This type of treatment is referred to as phage therapy. Phage therapy is effective against drug-resistant bacteria because bacteriophages are naturally inclined to infect and kill specific bacteria. [7] For the past two decades, studying phage therapy has grown in popularity with major research centers opening up in the United States, Poland ...
The George Eliava Institute of Bacteriophage, Microbiology and Virology [1] (aka Tbilisi Institute) has been active since the 1930s in the field of phage therapy, which is used to combat microbial infection (cf. antibiotic-resistant strains).
Phage therapy—viruses that specifically target pathogenic bacteria—has been developed over the last 80 years, primarily in the former Soviet Union, where it was used to prevent diarrhea caused by E. coli. [57] Presently, phage therapy for humans is available only at the Phage Therapy Center in the Republic of Georgia and in Poland. [58]
After this successful experiment on chicken, he felt ready for the first trial on humans. The first patient was healed of dysentery using phage therapy in August 1919. Many more followed. At the time, none, not even d'Hérelle, knew exactly what a phage was.
Phage therapy is under investigation as a method of treating antibiotic-resistant strains of bacteria. Phage therapy involves infecting bacterial pathogens with viruses . Bacteriophages and their host ranges are extremely specific for certain bacteria, thus, unlike antibiotics, they do not disturb the host organism's intestinal microbiota . [ 201 ]
