The effect of Lactobacillus plantarum ZS2058 (ZS2058) and eugenol on the intestinal microbiota composition at 2 days post-ST infection. Mice were pre-treated with regular diet and PBS (ST), regular diet and ZS2058 (Z), eugenol-contained diet and PBS (E), or eugenol-contained diet and ZS2058 (ZE) for 10 days before Salmonella infection. The control mice (C) were also pre-treated with regular diet and PBS but were not infected. When sacrificed at 2 days post-infection, cecal contents were collected for sequencing.

(B) PCA plot based on unweighted UniFrac metrics showing the constituents of Lactobacillus genus in each group. n = 5.
