Figure 1AB.The intake of Lactobacillus paracasei KW3110 in aged mice affected the gut microbial composition. Feces were collected and subjected to flora analysis in young (3-months-old) and aged mice (22-months-old). (A) Distribution of gut microbiota (% of total 16S rDNA) at the phylum level. (B) Comparison of the Firmicutes to Bacteroidetes ratio. Values are presented as the means ± SEM of relative abundance of each phylum.
