See also Comparison of computer viruses. This is an alphabetical list of biological virus families and subfamilies; it includes those families and subfamilies listed by the ICTV 2023 report. [1] For a list of individual species, see List of virus species. For a list of virus genera, see List of virus genera.
This is a list of all virus species, including satellites and viroids. Excluded are other ranks, and other non-cellular life such as prions. Also excluded are common names and obsolete names for viruses. The taxonomy is taken from ICTV taxonomy 2022 release [1] For a list of virus families and subfamilies, see List of virus families and ...
Antigen detection, polymerase chain reaction assay, virus isolation, and serology: Most infections are mild and require no therapy or only symptomatic treatment. Under research [1] Trypanosoma brucei: African sleeping sickness (African trypanosomiasis) Identification of trypanosomes in a sample by microscopic examination
A virus with this "viral envelope" uses it—along with specific receptors—to enter a new host cell. Viruses vary in shape from the simple helical and icosahedral to more complex structures. Viruses range in size from 20 to 300 nanometres; it would take 33,000 to 500,000 of them, side by side, to stretch to 1 centimetre (0.4 in).

A virus is a submicroscopic infectious agent that replicates only inside the living cells of an organism. [1] Viruses infect all life forms, from animals and plants to microorganisms, including bacteria and archaea. [2] [3] Viruses are found in almost every ecosystem on Earth and are the most numerous type of biological entity.
Illustrated sample of Duplodnaviria virions. Duplodnaviria contains double-stranded DNA (dsDNA) viruses that encode a major capsid protein (MCP) that has the HK97 fold. . Viruses in the realm also share a number of other characteristics involving the capsid and capsid assembly, including an icosahedral capsid shape and a terminase enzyme that packages viral DNA into the capsid during a
Many individually named viruses (sometimes referred to as "virus strains") exist at below the rank of virus species. The ICVCN gives the examples of blackeye cowpea mosaic virus and peanut stripe virus, which are both classified in the species Bean common mosaic virus, the latter a member of the genus Potyvirus that will in due course receive a ...
