Differences of gut microbiota compositions in depressed mice vs. control mice. A There were obvious differences of gut microbiota compositions between the two groups; B Relative abundances of OTUs in both groups assigned at the Family level; C The heat-map was built using the normalized abundance score for each differential OTU, and all OTUs were classified at phylum level. The r and p values from Pearson correlation method were represented by the color and size of each ellipse in scatter plot, respectively. DM depressed mice, n = 10, CM control mice, n = 10. IT immobility time, CD center distance, SPF sucrose preference, CT center time
