Composition of fecal microbiota from HBLC patients and healthy individuals. Data are represented as the average percentage of each individual profile. Fecal microbiota community analysis at the phylum, class, order, family levels demonstrated that the fecal microbiota from the HBLC patients contained a significant absence of Bacteroidetes (4% compared with 53% in the microbiota from the controls) and enrichment of Proteobacteria (43% compared with 4% in the microbiota from the controls), which included most of the pathogens. The microbiota in the HBLC patients showed a significant enrichment of Gammaproteobac (42%), Negativicutes (21%), and Bacilli (20%) at the class level, Enterobacteriales (41%), Selenomonadales(20%), and Lactobacillales (19%) at the order level, and Enterobacteriaceae (39%), Veillonellaceae (19%), and Streptococcaceae (18%) at the family level.
