Rarefaction analysis of the V3–V4 16S rRNA sequence to determine the changes in the
proportions of bacteria in the fecal samples of the dogs with inflammatory bowel
disease (IBD) between before and after fecal microbiota transplantation (FMT) and to
determine the proportions of bacteria in the fecal samples of the donor dogs. The
phyla are shown in order from the top of the bar graph: other, Tenericutes,
Proteobacteria, Fusobacteria, Firmicutes, Bacteroidetes, and Actinobacteria (Fig. 3A–C). The major bacterial phyla in the
dogs with IBD were Firmicutes (51.7%), as shown in Fig. 3A, and Proteobacteria (80.3%, 52.2%), as shown in Fig. 3B and C. The proportions of
Actinobacteria, Tenericutes, and Proteobacteria in the microbiome of donor dogs were
low, and the major bacterial phyla were Bacteroidetes, Firmicutes, and Fusobacteria.
Generally, the proportion of Fusobacteria decreased in the microbiome of dogs with
IBD.
