Reduction of richness in gut microbiota following vancomycin administration. Partial 16S rRNA-encoding gene sequences were obtained from the cecal mucosa (A) and cecal contents (B) from individual mice treated with 10 days of vancomycin (Vancomycin,V), animals that received 10 days of vancomycin followed by a three-week recovery period without antibiotic (Recovered, R) and animals that received no antibiotics (Control, C). Rarefaction curves were generated using mothur²⁰ and OTUs were defined at the 0.03 cutoff (97% similarity).
