1. Comparison between early-life and year 2 AMR levels.
Comparison between early-life and year 2 AMR levels. (A) There was a significant increase in the number of transferable ARGs present (as detected by ResFinder) in the high-Bifidobacterium infants between early life and year 2 (P = , Wilcoxon paired test). There was no significant difference in the number of transferable ARGs present in low-Bifidobacterium infants between the early-life and year 2 samples (P = 0.324, Wilcoxon paired test). (B) There was no significant difference in AMR abundance between early life and year 2 in infants who had high levels of Bifidobacterium in early life (P = 0.938, Wilcoxon paired test). There was a significant decrease in AMR abundance between early life and year 2 in infants who had low levels of Bifidobacterium in early life (P = , Wilcoxon paired test). P value for significance is 0.05.
