Figure 3.

Comparison of diversity indices and microbial compositions amongst groups after 4 weeks of oral administration. Alpha-diversities of microbial communities are shown as (A) richness and (B) evenness. (C) Principal Coordinates Analysis (PCoA) plot represents beta-diversity based on Bray-Curtis dissimilarity. (D) Taxonomic profiles at the phylum level (D) and the genus level (E). Relative Abundance of taxa below 0.1% were excluded prior to analyses. Significance was accepted at * p < 0.05, ** p < 0.01 (n = 8). Con, control; SZ, selenium and zinc supplemented; Lp, Lactobacillus plantarum SeZi; SZ + Lp, selenium- and zinc-enriched L. plantarum SeZi.
