(A) Gut microbiome profiles of healthy, common marmosets at the phylum level exhibit a Bacteroidetes-dominant and human-like microbiome. (B) Averaged relative abundances at the genus level show differences associated with source but few differences based on sex or age. (C) Observed OTUs were increased in MIT^NE vs. all sources, and MIT^B vs. MIT^A and MIT^CL, but metrics involving evenness, such as Shannon’s diversity index, showed no difference. Boxplots encompass the 25th and 75th percentiles of the distribution with the horizontal bar representing the median. *P < 0.05; **P < 0.01 and ***P < 0.001. (D) PCoA plot using Unweighted UniFrac metric shows clustering of microbiome profiles based on marmoset source.
