IBD patients have a different gut microbiome than healthy individuals, as evidenced by downregulation of Firmicutes and upregulation of Bacteroidetes , Actinobacteria , and Proteobacteria , and an increase in the Firmicutes-to-Bacteroides ratio

Rigorous, well-controlled human clinical trials are the necessary next step to validate these promising preclinical findings
their characteristics are presented in Table 1
