While knowledge was being accumulated regarding the biology of phages and how to use phage cocktails correctly, early uses of phage therapy were often unreliable. [29] Since the early 20th century, research into the development of viable therapeutic antibiotics had also been underway, and by 1942, the antibiotic penicillin G had been ...
George Eliava pioneered the use of phages in treating bacterial infections. Phages were discovered to be antibacterial agents and were used in the former Soviet Republic of Georgia (pioneered there by Giorgi Eliava with help from the co-discoverer of bacteriophages, Félix d'Hérelle) during the 1920s and 1930s for treating bacterial infections.
Production problems were most likely due to the attempt to mass-produce phages when they were barely understood. The phages may have been damaged and/or too low in concentration. Another possibility is that incorrect diagnoses led to the use of the irrelevant types of phages that were not adapted to the host bacteria of interest. Many studies ...
The ensuing Black Death may have killed up to 25 million total, including China and roughly a third of the population of Europe and in the next decades, changing the course of Asian and European history. Biologicals were extensively used in many parts of Africa from the sixteenth century AD, most of the time in the form of poisoned arrows, or ...
Pervitin, an early form of methamphetamine, was widely used in Nazi Germany and was available without a prescription. [1]The generally tolerant official drug policy in the Third Reich, the period of Nazi control of Germany from the 1933 Machtergreifung to Germany's 1945 defeat in World War II, was inherited from the Weimar government which was installed in 1919 following the dissolution of the ...
Many of the leaders of the emerging field of molecular biology were alumni of the phage course, which continued to be taught through the 1950s and 1960s. [ 24 ] [ 25 ] In 1995, Millard Susman published a retrospective article on the phage course as it was given over the years (1945 – 1970) both at Cold Spring Harbor (New York) and at the ...
Bacterial resistance to phages puts pressure on the phages to develop stronger effects on the bacteria. The Red Queen hypothesis describes this relationship, as the organisms must constantly adapt and evolve in order to survive. [15] This relationship is important to understand as phages are now being used for more practical and medicinal purposes.
The International Committee for Enteric Phage Typing was established in 1947, and these phage typing methods were soon standardized. [21] Improvements to the specificity of phage typing schemes were made throughout the next few decades. In 1959, Callow improved her initial scheme to differentiate 34 types of Salmonella typhimurium with 29 ...
