Frederick William Twort FRS [1] (22 October 1877 – 20 March 1950) was an English bacteriologist and was the original discoverer in 1915 of bacteriophages (viruses that infect bacteria). [4] He studied medicine at St Thomas's Hospital , London , was superintendent of the Brown Institute for Animals (a pathology research centre), and was a ...
The survival of some microorganisms exposed to outer space has been studied using both simulated facilities and low Earth orbit exposures. Bacteria were some of the first organisms investigated, when in 1960 a Russian satellite carried Escherichia coli, Staphylococcus, and Enterobacter aerogenes into orbit. [1]
Viruses were expected to be small, but the range of sizes came as a surprise. Some were only a little smaller than the smallest known bacteria, and the smaller viruses were of similar sizes to complex organic molecules. [14] In 1935, Wendell Stanley examined the tobacco mosaic virus and found it was mostly made of protein. [15]

Astro microbiology, or exo microbiology, is the study of microorganisms in outer space. It stems from an interdisciplinary approach, which incorporates both microbiology and astrobiology. Astrobiology's efforts are aimed at understanding the origins of life and the search for life other than on Earth.
Bacteria serve as natural hosts. There is only one species in this genus: Staphylococcus virus Twort. [1] [2] [3] Twortvirus is named as after the British bacteriological Frederick Twort. [citation needed]
The bacteria is usually only found in the mouth, far from the colon. In the mouth, it’s one of the most common types of disease-causing bacteria , linked to gum disease and plaque buildup.
Since the Apollo Program, there has been at least one independent investigation into the validity of the NASA claim. Leonard D. Jaffe, a Surveyor program scientist and custodian of the Surveyor 3 parts brought back from the Moon, stated in a letter to the Planetary Society that a member of his staff reported that a "breach of sterile procedure" took place at just the right time to produce a ...
