The human virome is the total collection of viruses in and on the human body. [ 1 ][ 2 ][ 3 ] Viruses in the human body may infect both human cells and other microbes such as bacteria (as with bacteriophages). [ 4 ] Some viruses cause disease, while others may be asymptomatic. Certain viruses are also integrated into the human genome as ...
Virome refers to the assemblage of viruses [1][2] that is often investigated and described by metagenomic sequencing of viral nucleic acids [3] that are found associated with a particular ecosystem, organism or holobiont. The word is frequently used to describe environmental viral shotgun metagenomes. Viruses, including bacteriophages, are ...
Viriome. The viriome of a habitat or environment is the total virus content within it. [1] A viriome may relate to the viruses that inhabit a multicellular organism as well as the phages that are residing inside bacteria and archaea. This term exists in contrast to the virome, which more commonly refers to the collection of nucleic acids ...
Viruses are by far the most abundant biological entities on Earth and they outnumber all the others put together. [ 89 ] They infect all types of cellular life including animals, plants, bacteria and fungi. [ 6 ]: 49 Different types of viruses can infect only a limited range of hosts and many are species-specific.
Virus classification. Virus classification is the process of naming viruses and placing them into a taxonomic system similar to the classification systems used for cellular organisms. Viruses are classified by phenotypic characteristics, such as morphology, nucleic acid type, mode of replication, host organisms, and the type of disease they cause.
The ratio of the number of infectious agents (e.g. individual viral particles) to the number of infection targets (e.g. cells of a particular host) within a defined space. mycovirus. Also sometimes called a mycophage. Any virus capable of infecting one or more species of fungi.
Double-stranded RNA viruses (dsRNA viruses) are a polyphyletic group of viruses that have double-stranded genomes made of ribonucleic acid.The double-stranded genome is used as a template by the viral RNA-dependent RNA polymerase (RdRp) to transcribe a positive-strand RNA functioning as messenger RNA (mRNA) for the host cell's ribosomes, which translate it into viral proteins.
Influenza virus life cycle. Entry. Replication. Latency. Shedding. Viruses are only able to replicate themselves by commandeering the reproductive apparatus of cells and making them reproduce the virus's genetic structure and particles instead. How viruses do this depends mainly on the type of nucleic acid DNA or RNA they contain, which is ...
