Antibiotic resistance gene abundance correlates with distance from the donor. a ARGs were quantified in metagenomic sequences (N = 21 patients and 4 donors) and summarized by mechanism. All ARG counts were transformed by log (ARG + 1) for visibility. b Two gene families within the β-lactamase class show opposite trajectories (N = 21 patients and 4 donors). c Patient-origin ARGs shown over time after RBX2660. d ARG abundance is plotted versus 1-(distance from donor) using weighted UniFrac. A generalized mixed effects log normal regression model of the formula ARGs ~ DFD + (1| PatientID) is shown, where DFD was significantly predictive of and correlated with ARG count compared to the null model (Chisq = 72.28, d.f.(full) = 1, p < 2.2 × 10−16). For c and d, all patients of both outcome groups were included for 153 total samples with patient N = 25 and donor N = 4. ac Significance was determined by pairwise Wilcoxon with Benjamini-Hochberg correction. *p < 0.05; **p < 0.001
