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.
Deep sequencing is a rapid DNA sequencing technique that is useful for characterizing virome richness, stability, gene function and the association with disease phenotypes. [ 1 ] [ 3 ] This technology creates large amounts of sequence information and is capable of detecting rare components of a microbial community.
One such surveillance program is the Global Virome Project (GVP) an international collaborative research initiative based at the One Health Institute at the University of California, Davis. [ 29 ] [ 30 ] The GVP aims to boost infectious disease surveillance around the globe by using low cost sequencing methods in high risk countries to prevent ...
The sequence-driven approach to screening is limited by the breadth and accuracy of gene functions present in public sequence databases. In practice, experiments make use of a combination of both functional and sequence-based approaches based upon the function of interest, the complexity of the sample to be screened, and other factors.
Diagram illustrating genomics. Omics is the collective characterization and quantification of entire sets of biological molecules and the investigation of how they translate into the structure, function, and dynamics of an organism or group of organisms.
Clinical metagenomic next-generation sequencing (mNGS) is the comprehensive analysis of microbial and host genetic material (DNA or RNA) in clinical samples from patients by next-generation sequencing. It uses the techniques of metagenomics to identify and characterize the genome of bacteria, fungi, parasites, and viruses without the need for a ...
Modern binning techniques use both previously available information independent from the sample and intrinsic information present in the sample. Depending on the diversity and complexity of the sample, their degree of success vary: in some cases they can resolve the sequences up to individual species, while in some others the sequences are ...
The goal of the Global Virome Project (GVP) is to identify and prevent future virus outbreaks. [4] The GVP is centered on the massive collection and sequencing of the planet's unknown viruses, with an estimated 1.6 million viral species yet to be discovered in mammal and bird populations. Of these, 631,000 to 827,000 have zoonotic potential. [4]
