Fig. 1From: Antibiotics-induced depletion of mice microbiota induces changes in host serotonin biosynthesis and intestinal motilityComposition of the mice intestinal microbiota after antibiotics at every level. And the relative abundance of microbiota at every level is measured and significant differences are found between two groups. a Phylum level; b class level; c order level; d family level; e geneus level; f species level.
