Abstract

The effect of gamma-aminobutyric acid (GABA) on the gut microbiota was evaluated in experiments on 47 rats with metabolic stress (MS) induced by food deprivation. MS was found to be associated with changes in the qualitative and quantitative composition of the caecum microbiota, including the redistribution of opportunistic flora, the growth of pathogenic microorganisms, as well as a decreased number of lactobacilli and bifidobacteria. Daily administration of GABA at a dose of 70 mg/kg during MS led to a decrease in the number of pathogens, thus leading to the restoration of normal eubionts in the cecum.

代谢应激时GABA对肠道微生物群的影响
采用47只食物剥夺引起代谢应激(MS)的大鼠,研究了γ -氨基丁酸(GABA)对肠道菌群的影响。MS与盲肠菌群的定性和定量组成的变化有关,包括机会菌群的重新分布,致病微生物的生长,以及乳酸菌和双歧杆菌数量的减少。在MS期间,每天给药70 mg/kg的GABA导致病原体数量减少,从而导致盲肠中正常益生菌的恢复。
