Virome Sequencing


Virome Sequencing

The human gastrointestinal microbiota represents one of the most complex ecosystems on earth. We now have the consensus that bacterial microbiota communities have been established since our birth and evolve over time to become 'adult-like' bacterial communities. DNA and RNA viruses, which include eukaryotic viruses, endogenous retroviruses, bacterial viruses and archaeal viruses, collectively make up the intestinal virome outnumber bacterial cells by as much as 10:1. Despite its predominance, our knowledge of gut viral communities is relatively deficient, as to both the acquisition and evolution.

Considering that viruses only replicate inside living cells, it is obvious that virome should not be studied in isolation. The human gut virome includes a diverse collection of viruses that infect our own cells as well as other commensal organisms, plays an important role in homeostatic regulation and disease progression, and directly or indirectly impact our well-being.

Due to the lack of universal marker, identifying virome information in large datasets is much more challenging than the cellular counterparts, which can easily be obtained through homology sequence searches against reference databases. In contrast to the sequencing of cellular organisms, extra sample preparation procedures are needed to enrich and purify viral particles, including filtration, ultracentrifugation, nuclease treatment, multiple displacement amplification (MDA), linker-amplified shotgun library (LASL), and random PCR approach. Along with the advances in high-throughput and deep sequencing technology, we are capable of characterizing virome richness and stability, gene functions, and association with disease phenotypes, which also helps to understand the richness of the virome and the role viruses play within complex microbial communities.
