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.
Phage therapy has gained recent attention in the United States as an alternative to standard antibiotic therapy. [ 5 ] [ 6 ] [ 7 ] It has been in practice for just over 100 years in countries such as Russia and Georgia , but due to the recent clinical attention of antibiotic resistance , Western countries have slowly been integrating phage ...
Since bacteria become resistant against a single phage, d'Herelle suggested using "phage cocktails" containing different phage strains. Phage therapy soon became a boom, and a great hope in medicine. In 1924, 25 January, d'Hérelle received the honorary doctorate of the University of Leiden , [ 14 ] as well as the Leeuwenhoek medal , which is ...
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). [105] The active phageome of a healthy human (i.e., actively replicating ...
Phage therapy is a good alternative to the use of antibiotics, but some bacteria have CRISPR-Cas systems. Nevertheless, if phages had Acr proteins, they would inhibit the CRISPR-Cas immune system and infect the cell. At the end of the phage reproduction cycle, which takes place inside bacteria, new phages would be released, provoking the cell ...
Dr. Elizabeth (Betty) Kutter is a phage biologist based at the Evergreen State College in Olympia, Washington, USA, where she is a Professor Emeritus.She led the T4 Genome Sequencing project, and organized the biennial Evergreen International Phage Biology meetings that draw hundreds of phage researchers from all over the world.
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. [55] Presently, phage therapy for humans is available only at the Phage Therapy Center in the Republic of Georgia and in Poland. [56]
[15] [16] As a result of the Patterson case, hundreds of other patients with multidrug resistant bacterial infections have been treated with intravenous phage therapy with the help of IPATH, including Joel Grimwood and Isabelle Carnell-Holdaway. Joel Grimwood was a patient who was ineligible for heart transplantation due to antimicrobial ...
