Clustering and composition of composite microbiota. For each subject in the study, adjoining the abundances of the top genera from the nasal swab and nasopharyngeal aspirate microbiotas created a composite microbiota sample. The Bray-Curtis dissimilarity was computed between each composite sample, and partitioning around medoids clustering was performed on the resulting dissimilarity values using 10 clusters. The heat map displays the abundances of the top seven genera for each of the resulting clusters, revealing common patterns of genus dominance between the nasal swab and nasopharyngeal microbiota. HAE, Haemophilus; MOR, Moraxella; STA, Staphylococcus; COR, Corynebacterium; ENT, Enterobacter; MIX, multiple genera; STR, Streptococcus
