Gut microbiota dysbiosis could aggravate the development of ulcerative colitis (UC). MN047 (CCMN) is a potential gut microbiota-regulating probiotic that could produce multiple novel bacteriocins. In this study, fecal microbiota transplantation (FMT) was used to verify whether CCMN could alleviate dextran sulfate sodium-induced UC by regulating gut microbiota. Results showed that both CCMN and FMT ameliorated the symptoms of UC, including attenuating the increased disease activity index, shortened colon length, gut barrier damage, and inflammation. Briefly, CCMN and FMT upregulated the expressions of MUCs and tight junctions, downregulated the expressions of proinflammatory cytokines and chemokines, increased fecal short-chain fatty acids, and lowered serum lipopolysaccharides, which were associated with the regulation of gut microbiota (e.g., increased , and levels). These results demonstrated that CCMN could ameliorate UC by modulating gut microbiota and inhibiting the TLR4/NF-κB pathway. Therefore, CCMN could be considered as a potential probiotic supplement for ameliorating UC.

Fecal microbiota transplantation (FMT) is currently used for treating infection and explored for other clinical applications in experimental trials. However, the effectiveness of this therapy could vary, and partly depend on the donor's bacterial species engraftment, whose evaluation is challenging because there are no cost-effective strategies for accurately tracking the microbe transference. In this regard, the precise identification of bacterial species inhabiting the human gut is essential to define their role in human health unambiguously. Read More
