Owing to its many roles in human health (1-3), there is great interest in deciphering the principles that govern the operations of an individual's gut microbiota.Current estimates indicate that each of us harbors several hundred bacterial species in our intestine (4, 5), and different diets lead to large and rapid changes in the composition of the microbiota (6, 7). Despite extensive studies in the field, researchers are still working on identifying the individual microbial species that live in our guts and understanding what roles they play in human health. Although the newly identified species are less prevalent in well-studied populations compared to reference isolate genomes, they improve classification of understudied African and South American samples by more than 200%. The human gut is home to many species of microbes, collectively referred to as the gut microbiota. 2019; 568: 499-504.
