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 ...
The first human virus to be identified was the yellow fever virus. [6] In 1881, Carlos Finlay (1833–1915), a Cuban physician, first conducted and published research that indicated that mosquitoes were carrying the cause of yellow fever, [ 7 ] a theory proved in 1900 by commission headed by Walter Reed (1851–1902).
Comparative sequence analyses of bacteriophage WO [80] offer some of the most compelling examples of large-scale horizontal gene transfer between Wolbachia coinfections in the same host. [81] It is the first bacteriophage implicated in frequent lateral transfer between the genomes of bacterial endosymbionts. Gene transfer by bacteriophages ...
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 ...
The existence of the eerily-nicknamed viruses has been known to researchers for decades, but this is the first time traces of the viruses have been discovered in the US.
The eldest of the eleven children of Dr. William Henry Twort, Frederick Twort was born in Camberley, Surrey on 22 October 1877. [1] The three eldest sons went to Tomlinson's Modern School in Woking. [7] From 1894 Frederick studied medicine at St Thomas's Hospital, London.
Dating back to the 1940s and continuing today, T-even phages are considered the best studied model organisms. Model organisms are usually required to be simple with as few as five genes. Yet, T-even phages are in fact among the largest and highest complexity virus, in which these phage's genetic information is made up of around 300 genes.
