Gut microbiota in 2015

Prevotella in the gut: choose carefully

Gut microbial communities often contain many Bacteroides or their close relatives, Prevotella, but not both. Prevotella strains are associated with plant-rich diets but are also linked with chronic inflammatory conditions. In 2015, papers probed the genomic diversity of Prevotella strains and interactions of Prevotella copri with its host and other bacteria.
