摘要： Probiotics are widely recognized for their ability to prevent and therapy antibiotic-associated diarrhea (AAD). This study was designed to evaluate Lactiplantibacillus plantarum ELF051 ability to prevent colon inflammation and its effect on gut microbial composition in a mouse model of AAD. The mice were intragastrically administered triple antibiotics for 7 days and then subjected to L. plantarum ELF051 for 14 days. The administration of L. plantarum ELF051 ameliorated the pathological changes in the colon tissue, downregulated interleukin (IL)-1 beta and tumor necrosis factor (TNF)-alpha, and upregulated IL-10, and increased the intestinal short-chain fatty acids (SCFAs) level. Lactiplantibacillus plantarum ELF051 also regulated the Toll-like receptor/myeloid differentiation primary response 88/nuclear factor kappa light chain enhancer of activated B cells (TLR4/MyD88/NF-.B) and the phosphatidylinositol 3-kinase/protein kinase B/ NF-kappa B (PI3K/AKT/ NF-kappa B) inflammatory signaling pathways. 16S rRNA analyses showed that L. plantarum ELF051 increased the abundance and diversity of gut bacteria, restoring gut microbiota imbalance. A Spearman's rank correlation analysis showed that lactobacilli are closely associated with inflammatory markers and SCFAs. This work demonstrated that L. plantarum ELF051 can attenuate antibiotic-induced intestinal inflammation in a mouse AAD model by suppressing the pro-inflammatory response and modulating the gut microbiota.
