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 ...
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 ...
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 ...
Viral metagenomics. Environmental Shotgun Sequencing (ESS) (A) Sampling from habitat. (B) filtering particles, typically by size. (C) Lysis and DNA extraction. (D) cloning and library construction. (E) sequencing the clones. (F) sequence assembly into contigs and scaffolds. Viral metagenomics uses metagenomic technologies to detect viral ...
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.
A viral disease (or viral infection) occurs when an organism's body is invaded by pathogenic viruses, and infectious virus particles (virions) attach to and enter susceptible cells. [1] Examples are the common cold, gastroenteritis and pneumonia. [2]
