Rarefaction curves. The curve is created for each sample to assess the saturation at different sequencing depths for recovery of bacterial taxa presented by amplicon sequence variants (ASVs). Nasopharyngeal aspirate and nasal swab samples reach a plateau more rapidly (~ 10,000 reads) compared to saliva samples (~ 50,000 reads).
