Taxonomic distribution of fecal microbiome of piglets. A The majority of bacterial species identified in all fecal samples belonged to the phylum Firmicutes, followed by Bacteroidetes and Proteobacteria, irrespective of the litters. B Top 20 genera present in different litters over the course of experiment (3 w, 8 w, 12 w = 3, 8 and 12 weeks of age, respectively). Litters were represented in sequential numbers 0–5. L0 included uninoculated control piglets. Litters 1–5 included all M. hyopneumonaie experimentally inoculated piglets.
