Figure 1.

Comparison of the taxonomic composition of the top 15 ASVs in CF sputum through the course of incident S. maltophilia infection (n = 25) and uninfected controls (n = 56). Relative abundance was collected at the genus level for samples at pre-infection (samples = 57; median 5.1 months from incident infection date [interquartile range (IQR) 2.7–6.9 months)], at-infection (samples = 22), and post-infection (samples = 31; median 3.0 months from incident infection date [IQR 2.0–5.0 months)], and control samples corresponding to case infection dates.
