The blood–brain barrier (BBB) contributes to the maintenance of brain homeostasis. Gut microbiome composition affects BBB development and expression of tight junction proteins in rodents. However, we still do not know if there is any direct effect of gut microbial composition on BBB permeability and function in normal adult animals. In the current study, we determined temporal and spatial changes in BBB permeability of rhesus monkeys receiving amoxicillin‐clavulanic acid (AC) by monitoring the cerebrospinal fluid/serum albumin ratio and the volume transfer constant ( K trans ). We showed that oral, but not intravenous, AC was associated with subsequent significant alteration in gut microbial composition and an increase in BBB permeability in all monkeys, especially in the thalamus area. Acetic and propionic acids might play a pivotal role in this newly found communication between the gut and the central nervous system. Antibiotic‐induced gut microbial composition change, especially the decrease in acetic acid– and propionic acid–producing phyla and genera, might have a potential effect on the increase in BBB permeability, which may contribute to a variety of neurological and psychological diseases.
