Diversity and abundances of predominant families in fecal communities of multiple-course antibiotic-treated mice. a Average Shannon indices of fecal communities from mice receiving antibiotics and donor gavage. Bars sharing the same letter did not differ significantly by Tukey’s post hoc test (P < 0.05). b Predominant families from mice that received gavage from donor 36. c Predominant families from mice that received gavage from donor 41. d Predominant families from mice that received gavage from donor 42. All values were averaged among replicates from donors (n = 3, each), and mice receiving gavage from donors 36, 41, and 42 (n = 4, 5, and 2, respectively). Donor and mouse similarity refer to SourceTracker analyses, where the source mouse community was taken as the pre-antibiotic time point for donor 41 only (same lot as used in the germ-free experiment)
