Strain-level metagenomics

Identifying unknown bacterial strains in metagenomics samples.

What is a bacterial strain?

Family - Genus - Species - Strain

A strain is a low-level taxonomic rank describing genetic variants or subtypes of a species. Theoretically, a strain lineage refers to genetically identical genomes, but practically also closely related variants are considered as the same strain. With an increasing number of mutations or acquisition of new genes (HGT) a strain can evolve in an order to be considered as a different strain.
