摘要

The study evaluated the effectiveness of a synbiotic blend containing Lactococcus lactis KA-FF 1–4 and Fibersol-2 in modulating gut microbiota and inhibiting vancomycin-resistant Enterococcus (VRE). Compared to probiotic or prebiotic treatments alone, the synbiotic blend significantly altered the gut microbiota composition, increasing beneficial bacteria like Blautia, Clostridium, Parabacteroides, Prevotella, and Roseburia, while reducing VRE abundance. Moreover, the synbiotic treatment showed an increase in short-chain fatty acid (SCFA) concentrations, particularly acetate, propionate, and butyrate. Correlation analysis revealed that enriched taxa in the synbiotic treatment were positively associated with higher SCFA levels. These findings highlight the potential of synbiotic formulations in improving gut microbiota balance and combating antibiotic-resistant pathogens like VRE.
