Antibacterial drug treatment increases the bile acid pool size and hepatic bile acid concentration through the elevation of hepatic bile acid synthesis. However, the involvement of intestinal bile acid absorption in the increased bile acid pool size remains unclear. To determine whether intestinal bile acid absorption contributes to the increased bile acid pool in mice treated with antibacterial drugs, we evaluated the levels of bile acid transporter proteins and the capacity of intestinal bile acid absorption. Ileal apical sodium-dependent bile acid transporter (ASBT) mRNA and protein levels were significantly increased in ampicillin (ABPC)-treated mice, whereas organic solute transporter α (OSTα) mRNA levels, but not protein levels, significantly decreased in mice. Similar alterations in the expression levels of bile acid transporters were observed in mice treated with bacitracin/neomycin/streptomycin. The capacity for intestinal bile acid absorption was evaluated by an in situ loop method. Increased ileal absorption of taurochenodeoxycholic acid was observed in mice treated with ABPC. These results suggest that intestinal bile acid absorption is elevated in an ASBT-dependent manner in mice treated with antibacterial drugs.
