Typical indigenous bacteria in the cecum of ddY mice fed casein-beef tallow diet or whole egg diet

Differences in the gut microbiome between the mice fed the CT diet and Egg diet for 14 days were clearly demonstrated. Bacteroides sp. and F. rodentium were detected by the 16S rDNA amplicon sequencing as casein-beef tallow-SIB and whole egg-SIB in the gut microbiome of ddY mice. Furthermore, the SIB were isolated on BL agar and identified as B. caecimuris and F. rodentium. The functional effects of the SIB isolates on host health have to be clarified in the future.
