Host-Derived Bacillus velezensis enhances intestinal structure, antioxidant capacity, and pathogen resistance in the American bullfrog (Aquarana catesbeiana)
The samples used for gut microbiome analysis in this study were sterilely collected from the posterior gut contents of the bullfrog (Aquarana catesbeiana). The experimental animals were randomly divided into two groups: the control group (fed a basal diet) and the BLS experimental group (fed a diet supplemented with 1x10^8 CFU/g of Bacillus velezensis BLS).
