Highlights
- • The gut microbiome was compared in high- and low-functioning (HF, LF) older adults.
- • Fecal transfer from HF and LF older adults into germ-free mice was performed.
- • Bacteria were identified that differed between HF and LF older adult humans.
- • Similar bacterial differences were identified for HF-and LF-colonized mice.
- • Grip strength was higher in HF-, when compared with LF-colonized mice.
