摘要： Lactic acid bacteria play a crucial role in maintaining the health of the host's gut microbiota. In this study, the anti-inflammatory properties of Limosilactobacillus reuteri LR20-6 and Lacticplantibacillus plantarum L272 were evaluated using a mouse model of diarrhea induced by Escherichia coli. We also investigated their effects on gut microbiota regulation. The results indicated that both Lacticplantibacillus plantarum and Limosilactobacillus reuteri could reduce inflammation by inhibiting the expression of inflammatory factors IL-6 and TNF-alpha and blocking the MyD88 and NF-kB/p65 signaling pathways. Additionally, after intervention with these strains, the relative abundance of Lactobacillus was significantly increased. This suggested that Lacticplantibacillus plantarum and Limosilactobacillus reuteri could mitigate the severity of E. coli-induced diarrhea and enhance the abundance of beneficial probiotics in the gut of animals.
