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 specimens usually comprise an overwhelming amount of host nucleic acids, which by far exceeds the number of pathogen nucleic acids in the sample. Subsequently, it is necessary to either decreas...
