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.
Mycobacteriophage Bxb1 Structure [1]. A mycobacteriophage is a member of a group of bacteriophages known to have mycobacteria as host bacterial species. While originally isolated from the bacterial species Mycobacterium smegmatis and Mycobacterium tuberculosis, [2] the causative agent of tuberculosis, more than 4,200 mycobacteriophage species have since been isolated from various environmental ...
Phage therapy is a technique that was discovered before antibiotics, but fell to the wayside as antibiotics became predominate. It is now being considered as a potential solution to increasing antimicrobial resistance. Bacteriophages, viruses that only infect bacteria, can specifically target the bacteria of interest and inject their genome ...
Phage therapy also allows for the possibility of biofilm penetration in cases where antibiotics are ineffective due to the increased resistance of biofilm-forming pathogens. [9] One major drawback to phage therapy is the evolution of phage-resistant microbes which was seen in a majority of phage therapy experiments aimed to treat sepsis and ...
Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.
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 ]
Several laboratories have been testing suitability of bacteriophage isolates to control certain bacterial pathogens. Significant advancements in this research have been made at the Bacteriophage Institute in Tbilisi, Georgia, where phage therapy is routinely applied in medicine research. Today treatment of antibiotic resistant bacteria is a ...
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 ...
