Microbiota composition in stool samples from WT and IL-10^−/− mice after 35 days of treatment with PM₁₀.

<p>Stool was analyzed using T-RFLP. (A) Relative abundance of phyla. Table provides mean ± SEM for each phylum as the percentage of total sequences. (B) Bacteria communities were clustered using partial least squares discriminant analysis (PLS-DA). WT mice clustered independently from IL-10 mice, and PM₁₀ treatment shifted the microbiota in both WT and IL-10^−/− groups. WT control: Black squares (n = 9); IL-10^−/− control: Blue triangles (n = 6); WT+PM₁₀: Red circles (n = 3); IL-10^−/−+PM₁₀: green crosses (n = 3).
