The 16S rRNA gene was sequences from total DNA extracted from stool or filtered fecal sediment (Human). There were ∼1 million sequences per sample generated and matched to species or family. All fecal samples were collected from the village of Jenipapo, 10 humans, 2 cows, 3 pigs, 3 dogs, and 2 horses. Species of the genus Blautia are one component of the Lachno2 group.
