Bacteriophage genomes can be highly mosaic, i.e. the genome of many phage species appear to be composed of numerous individual modules. These modules may be found in other phage species in different arrangements. Mycobacteriophages, bacteriophages with mycobacterial hosts, have provided excellent examples of this mosaicism.
d'Hérelle was a self-taught microbiologist. In 1917 he discovered that "an invisible antagonist", when added to bacteria on agar, would produce areas of dead bacteria. The antagonist, now known to be a bacteriophage, could pass through a Chamberland filter. He accurately diluted a suspension of these viruses and discovered that the highest ...
[32] [33] A summary of these publications was published in English in 2009 in "A Literature Review of the Practical Application of Bacteriophage Research". [34] There is an extensive library and research center at the George Eliava Institute in Tbilisi, Georgia. Phage therapy is today a widespread form of treatment in that region. [25] [24]
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 ...
In 1856, scientists began studying a skeleton found in Germany's Neander Valley. The bones resembled a human's but differed in several key ways: the skull was longer and the limbs were thicker ...
The phage group started around 1940, after Delbrück and Luria had met at a physics conference. Delbrück and Salvador Luria began a series of collaborative experiments on the patterns of infection for different strains of bacteria and bacteriophage. They soon established the "mutual exclusion principle" that an individual bacterium can only be ...
A number of “vampire viruses” have been discovered in soil samples in Maryland and Missouri for the first time.. The existence of the eerily-nicknamed viruses has been known to researchers for ...
Phageome research in humans has largely focused on the gut, however it is also being investigated in other areas like the skin, [8] blood, [9] and mouth. [10] The composition of phages that make up a healthy human gut phageome is currently debated, since different methods of research can lead to different results. [ 11 ]
