Abstract
Clinical metagenomics (CMg), based on whole-genome sequencing of clinical samples, offers the potential to directly detect all microorganisms present in a sample. This approach could, therefore, provide potential unbiased detection of all microorganisms present in the sample, including those organisms that are fastidious or even cannot be cultivated. It constitutes a rapid and generic approach providing all medically-actionable information: the presence or the absence of microorganisms (detection), their identification to the species level or even beyond (speciation), the detection of antimicrobial resistance determinants, with the potential to guide antibiotic therapy and virulence-associated genes.
This chapter aims at describing current common hurdles encountered when attempting to utilise CMg to clinical samples (such as sample preparation and wet lab issues and bioinformatic challenges) and discuss ways to overcome them. We will also review the current experience with using CMg in clinical samples from different anatomical sites.
