Abstract:

The aim of this study was to investigate the effects of maternal supplementation with Lactiplantibacillus plantarumX86 during pregnancy and lactation on early offspring development and gut microbiota. Sixteen gregnant SD rats were selected and divided into control group (n=8) and L. plantarumX86 group (n=8). Rats in the L. plantarumX86 group were given Lactiplantibacillus plantarumX86 gavage from late pregnancy until early lactation. The impact on offspring growth, intestinal barrier function, and gut bacterial community structure were evaluated by various indexes. Results showed that L. plantarumX86 supplementation increased body weight at 7 and 14 days of age, and elevated heart and liver coefficients of the offspring; However, it reduced the white blood cell counts and hemoglobin content. Additionally, L. plantarum X86 supplementation downregulated IL-6 mRNA expression and upregulated Occludin mRNA expression in the intestines of rat offspring. 16S rRNA sequencing analysis revealed that the maternal supplementation with L. plantarumX86 during late pregnancy and lactation significantly altered the gut microbiota in rat offspring, increasing the relative abundance of Lactobacillus and Romboutsia while reducing that of Escherichia-Shigella, Staphylococcus, and Akkermansia. A broad reduction in KEGG metabolic pathway abundance was also observed. In conclusion, consumption of L. plantarumX86 during late pregnant and early lactation promotes offspring growth and development, and exerts beneficial effects on the gut barrier function and bacterial microbiota composition.
