The phi X 174 (or ΦX174) bacteriophage is a single-stranded DNA virus that infects Escherichia coli. This virus was isolated in 1935 by Nicolas Bulgakov [1] in Félix d'Hérelle's laboratory at the Pasteur Institute, from samples collected in Paris sewers. Its characterization and the study of its replication mechanism were carried out from ...
Structural model at atomic resolution of bacteriophage T4 [1] The structure of a typical myovirus bacteriophage Anatomy and infection cycle of bacteriophage T4.. A bacteriophage (/ b æ k ˈ t ɪər i oʊ f eɪ dʒ /), also known informally as a phage (/ ˈ f eɪ dʒ /), is a virus that infects and replicates within bacteria and archaea.
Filamentous bacteriophages are a family of viruses (Inoviridae) that infect bacteria, or bacteriophages.They are named for their filamentous shape, a worm-like chain (long, thin, and flexible, reminiscent of a length of cooked spaghetti), about 6 nm in diameter and about 1000-2000 nm long.
Often simply called an antiviral. A class of antimicrobial medication used specifically for treating diseases caused by viral infections rather than ones caused by bacteria or other infectious agents. Unlike most antibiotics, antivirals typically do not destroy their target viruses but instead inhibit their development. They are distinct from virucides. assembly The construction of the virus ...
[13]: 631 The viruses that infect plants are harmless to animals, and most viruses that infect other animals are harmless to humans. [6]: 272 The host range of some bacteriophages is limited to a single strain of bacteria and they can be used to trace the source of outbreaks of infections by a method called phage typing. [90]
Diverse viruses colonize the human skin and differ by skin site. [27] This skin virome includes human viruses (i.e. human papillomavirus) and bacteriophages (bacterial viruses) that infect commensal skin bacteria such as Staphylococci. [28] Virus communities differ by moisture levels and degree of protection from the external environment. [27]
There are more than 200 different types of viruses that can cause a common cold, which is usually just a mild infection in the upper respiratory tract, hence the feeling of a sore throat, runny ...
For the viruses that infect bacteria, the bacteriophages, the bacteria growing in test tubes can be used directly. For plant viruses, the natural host plants can be used or, particularly when the infection is not obvious, so-called indicator plants, which show signs of infection more clearly.
