Salt intake reduced the gut microbiota diversity and disrupted salt/water homeostasis. Caecal microbiota transplant (CMT) from the control to salt-treated gerbils improved the gut microbiota community with enriched beneficial bacteria such as Lactobacillus reuteri, but decreased potential pathogenic bacteria such as Parabacteroides distasonis and Prevotella copri. The recovery in gut bacteria and increase in short chain fatty acids, particularly butyrate, after CMT was linked with alterations in intestinal and renal proteins, including aquaporin 2 (AQP2), epithelial sodium channel α (α-ENaC), free fatty acid receptor 2 (FFAR2) and cAMP–PKA, which play roles in osmoregulation and microbial signals.
