Tunalikevirus
''Tunavirus'' (synonyms ''T1-like phages'', ''T1-like viruses'', ''Tunalikevirus'') is a genus of viruses in the order '' Caudovirales'', in the family '' Drexlerviridae''. Bacteria serve as natural hosts. There are currently 14 species in this genus, including the type species '' Escherichia virus T1''. Taxonomy The following species are recognized: * '' Escherichia virus ADB2'' * '' Escherichia virus BIFF'' * '' Escherichia virus IME18'' * '' Escherichia virus JMPW1'' * '' Escherichia virus JMPW2'' * '' Escherichia virus SH2'' * '' Escherichia virus T1'' * '' Shigella virus 008'' * '' Shigella virus ISF001'' * '' Shigella virus PSf2'' * '' Shigella virus Sfin1'' * '' Shigella virus SH6'' * '' Shigella virus Shfl1'' * '' Shigella virus ISF002'' Structure Tunaviruses are nonenveloped A viral envelope is the outermost layer of many types of viruses. It protects the genetic material in their life cycle when traveling between host cells. Not all viruses have envelopes. Numerous ...

Virus
A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. Since Dmitri Ivanovsky's 1892 article describing a non-bacterial pathogen infecting tobacco plants and the discovery of the tobacco mosaic virus by Martinus Beijerinck in 1898,Dimmock p. 4 more than 9,000 virus species have been described in detail of the millions of types of viruses in the environment. Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity. The study of viruses is known as virology, a subspeciality of microbiology. When infected, a host cell is often forced to rapidly produce thousands of copies of the original virus. When not inside an infected cell or in the process of infecting a cell, viruses exist in the form of independent particles, or ''virions'', consisting of (i) the genetic material, i. ...
