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 ...
A systematic exploration of the viruses that infect humans (the human virome) is important and feasible with these methods. Polymerase chain reaction is a tool to amplify and detect specific DNA sequences. It can be used to help characterize the virome, but it is limited by the need for at least partial DNA sequence information.
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.
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.
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 ...
VirCapSeq is a system to broadly screen for all viral infections in vertebrates including humans. [1] It was designed by W. Ian Lipkin, Thomas Briese, and Amit Kapoor at Columbia University.
Metagenomic sequence-based analyses have been used to predict around 57 complete and partial virophage genomes [82] and in December 2019 to identify 328 high-quality (complete or near-complete) genomes from diverse habitats including the human gut, plant rhizosphere, and terrestrial subsurface, from 27 distinct taxonomic clades.
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 ...
