Microbial abundance and diversity in mice following antibiotics treatment and transplants of human fecal matter. a–c The gut bacterial abundance (operational taxonomic units, OTUs) and diversity (Chao1 index and Shannon index) in mice was significantly lower after treatment with broad-spectrum antibiotics in drinking water for 3 weeks, n = 20 mice. d–f The mice that received human fecal transplants over 28 days exhibited higher gut bacterial abundance and diversity than the PBS FMT group (no fecal transplants), n = 10 mice. *p < 0.05, **p < 0.01
