Dietary iron during recovery from antibiotic exposure significantly affects gut microbiota functions. Normalized relative abundances of Kyoto Encyclopedia of Genes and Genomes (KEGG): A primary bile acid biosynthesis, B nitrogen metabolism, C cyanoamino acid metabolism, and D pentose phosphate pathways were detected as significantly different by White’s t-test between mice under iron-sufficient and iron excess diet at T80. Bars represent the standard error of the mean (SEM). (N = 9)
