Fig. 1From: Improving saliva shotgun metagenomics by chemical host DNA depletionPercent of shotgun metagenome sequencing reads aligning to human genome varies by sample type. Data from the Human Microbiome Project (HMP; black) of healthy individuals demonstrates the percentage of human reads by sample type. Saliva data (blue) was collected from healthy individuals in this study. Stool n = 249, skin n = 29, vaginal n = 103, nasal cavity n = 112, inner cheek n = 175, tongue n = 208, gums n = 189, and saliva n = 24 (this study)Back to article page
