In order to study viruses in the environment, scientists isolate nucleic acids from an environmental sample, sequence them, and use computers to assemble genomes and compare them to known sequences in databases. This approach is known as Metagenomics.
- The study of whole nucleotide sequences that have been extracted and examined from all of the organisms (usually bacteria) in a bulk sample is known as metagenomics.
- Metagenomics is frequently used to investigate a particular population of microbes, such as those found in soil, water, or on human skin.
- The study of viral genetic material that is derived directly from the environment rather than from a host or natural reservoir is known as viral metagenomics.
- In research focusing on certain potential reservoirs, viral diversity in the environment is frequently overlooked.
- Without the need to isolate and grow viral species in the lab, it provides crucial information on virus evolution and the genetic diversity of the viral population.
