...nity to study i.e. whole ecosystems. Basically, the metagenomics approach is similar to well-known shotgun-sequencing, though on a much bigger scale. For instance, the metagenome of a lake would include all the fish, ducks, plants, fungi, bacteria and everything else that belongs to the lake. If we apply this approach to clinical samples we can identify the community of etiological pathogens, without any knowledge on the targets in advance. However, clinical s...
