This study examined if healthy gut microbiota of sham male rats (Sham+V) and dysbiotic gut microbiota of NP rats (spinal nerve ligation: NP, SNL+V) can be disrupted and restored, respectively, via fecal microbiota transplant (FMT) from the opposite group [Sham+(SNL-FMT) and SNL+(Sham-FMT), respectively]. All groups received FMT daily for two weeks, followed by three weeks without FMT. SNL rats showed higher mechanical hypersensitivity [SNL+V vs. Sham+V] throughout the study. After two weeks, the FMT of healthy gut microbiota decreased mechanical hypersensitivity in SNL rats [SNL+(Sham-FMT) vs. SNL+V]. A temporal shift in microbiome profiles after 2-week FMT treatment was observed in Sham+(SNL-FMT) and SNL+(Sham-FMT) groups, while the microbiome profile shifted back a certain extent after FMT ceased. At the end of study, the Sham+(SNL-FMT) group acquired low abundance of UCG-001, Odoribacter, and Peptococcaceae, and high abundance of UBA1819 and Victivallis. The SNL+(Sham-FMT) group maintained high abundance of Butyricimonas and Escherichia-Shigella. The SNL+(Sham-FMT) group had altered glial and macrophage activation/inflammation markers in the brain/colon than the SNL+V group. Relative to the SNL+V group, the SNL+(Sham-FMT) group had significantly lower gene expressions of GFAP (hypothalamus), IBA-1 (colon), and NF-κB (amygdala/colon), but higher gene expressions of complex I (amygdala/hypothalamus) and claudin-3 (amygdala/hypothalamus/colon).
