Abstract

The dysbiosis of gastrointestinal microbiome is an important reason for burn-induced intestinal injury. Clostridium butyricum (C.butyricum) and its production butyrate are beneficial for the homeostasis of intestinal microflora and suppression of inflammatory response. The roles of C.butyricum and butyrate in burn-induced intestinal injury were explored. The effects of oral administration of C.butyricum on intestinal injury were observed in burned mice. The skin surface of mice was exposed to 95 °C water to induce a burn injury. Then the intestinal microbiome structure, abundance of C.butyricum and level of butyrate were respectively observed. The correction between intestinal permeability indicated by FITC dextran level and abundance of C.butyricum or level of butyrate was analyzed. C.butyricum was cultured and orally administrated to burned mice. The levels of butyrate, FITC dextran and pro-inflammatory cytokines, including interleukin 6 (IL-6) and tumor necrosis factor α (TNF-α) were respectively measured. Burn injury altered the intestinal microbiome structure of mice, and especially decreased the abundance of C.butyricum and level of butyrate. Both the abundance of C.butyricum and the level of butyrate were negatively correlated with the intestinal permeability. Oral administration of C.butyricum increased the level of butyrate, decreased levels of TNF-α and IL-6, and suppressed intestinal damage in burn-injured mice. Oral administration of C.butyricum significantly alleviated the intestinal damage induced by burn injury. The therapeutic effects of C.butyricum and butyrate on burn injury should be further explored, which deserves further investigation. Copyright © 2020 Elsevier Ltd and ISBI. All rights reserved.
