Relative bacterial abundance in selected families (F) and genera (G).

<p>Ileum: (a) Streptococcaceae, (b) <i>Escherichia/Shigella</i>, (c) <i>Lactococcus</i>, (d) unclassified Lachnospiraceae. Cecum: (e) Ruminococcaceae, (f). Clostridiaceae_1, (g) <i>Escherichia/Shigella</i>, (h) <i>Butyricicoccus</i>, (i) <i>Erysipelotrichaceae</i> incertae sedis. Reads were normalized to total number of reads per sample. * = p<0.05, ** = p<0.01, *** = p<0.001. Data were analyzed using the Mann-Whitney <i>U</i> test.
