Figure 3. The abundance of microbes that changed with age or CR in C57BL/6 mice. The relative abundance of the 34 microbes that changed significantly in C57BL/6JN mice are shown for adult mice fed AL (A-AL) or CR (A-CR) and old mice fed AL (O-AL) or CR (O-CR). The microbiome data are presented on the basis of family (A), genus (B), or species (C) of the microbes found in either the cecum or colon of the mice.
