Prevotella species in the human gut is primarily comprised of Prevotella copri, Prevotella stercorea and related lineages.

Prevotella species in the human gut microbiome are primarily comprised of Prevotella copri, and its diversity and function were recently investigated in detail. Much less is known about other Prevotella species in the human gut. Here, we examined the composition of Prevotella species in human guts by mapping publicly available gut metagenomes to a dereplicated set of metagenome-assembled genomes (MAGs) representing Prevotella lineages found in human guts.
