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 .
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 ...
Phage therapy is the method by which bacteriophages (viruses which infect bacteria) are used to treat bacterial infections or reduce bacterial populations. Phage therapy has gained recent attention in the United States as an alternative to standard antibiotic therapy.
In July 2007, the same bacteriophage were approved for use on all food products. [37] In 2011 USDA confirmed that LISTEX is a clean label processing aid and is included in USDA. [38] Research in the field of food safety is continuing to see if lytic phages are a viable option to control other food-borne pathogens in various food products. [39]
This phage-display library is added to the dish and after allowing the phage time to bind, the dish is washed. Phage-displaying proteins that interact with the target molecules remain attached to the dish, while all others are washed away. Attached phage may be eluted and used to create more phage by infection of suitable bacterial hosts. The ...
A more detailed account of the use of phage in major biological discoveries can be found on the page, bacteriophage. As one of the earliest applied microbiologists, d'Hérelle's microbe-centered worldview has been noted for its prescience, since microbes are playing increasingly important roles in bioremediation , microbial fuel cells , gene ...
The RM system was first discovered by Salvatore Luria and Mary Human in 1952 and 1953. [1] [2] They found that a bacteriophage growing within an infected bacterium could be modified, so that upon their release and re-infection of a related bacterium the bacteriophage's growth is restricted (inhibited; also described by Luria in his autobiography on pages 45 and 99 in 1984).

The Eliava Institute's facilities were damaged and decades of research on bacteriophage nearly went down the drain. Thousands of bacteriophage samples identified over the years and catalogued in huge, refrigerated "libraries" suffered irreversible damage due to frequent electrical outages.
