Barplots of compositional mean relative abundances of the 20 most abundant nasopharyngeal (NP) bacterial genera detected in 103 participants during the first 30 months of life. Each barplot represents compositional mean relative abundances for each of the 20 most abundant NP bacterial genera at each of the timepoints. The 20 most abundant bacterial genera were identified as the 20 bacterial genera with the highest sum of mean relative abundances across the first 30 months of life. Specimen collection age (in months) and the number of specimens analyzed at each of the timepoints are shown on the X-axis. Shades of colors are used to present phylum-level classification [shades of blue: Proteobacteria (and Campilobacterota, previously Epsilonproteobacteria), shades of yellow: Actinobacteria, shades of red: Firmicutes, shades of pink: Fusobacteriota, shades of green: Bacteroidetes]
