This paper identifies Bacillus velezensis GFZF-23 as a probiotic that alleviates colitis by restoring the microbiome and reprogramming host metabolism through β-sitosterol.

This study establishes a long-term germ-free medaka model to investigate microbiota-dependent effects on growth, immunity, and metabolism, finding that gut-derived metabolites partially restore developmental and immune deficits but not long-term survival.
