Gut morphology, not just diet or phylogeny, shapes mammalian gut microbiomes

Researchers analyzed over 1,400 gut microbiome samples from 292 mammalian species to find distinct gut microbiomes corresponding to different gut morphology types. These microbiomes were grouped into three enterotypes: Fusobacterium in simple-gut species, UCG-005 in foregut fermenters, and Prevotella in hindgut fermenters.
