Fig. 1: Resistome composition in the nasopharynx microbiome of preterm infants.

Stacked bar plots showing the relative abundance of A antibiotic resistance genes (ARGs) clustered at the Class level for the naive and early antibiotic-treated groups over time; and B the top 30 most abundant ARGs identified across samples at baseline (T1) in antibiotic-treated (left) and naive (right) groups. All other ARGs are grouped into the “Others” category. MLS macrolide-lincosamide-streptogramin. Source data are provided as a Source data file.
