From: Improving saliva shotgun metagenomics by chemical host DNA depletion
Host DNA depletion in saliva reduces the percentage of sequencing reads aligning to the human genome. Saliva was collected from eight individuals and divided into triplicate aliquots for each of the processing methods. The fraction of quality filtered shotgun sequencing reads mapping to the human genome was assessed with Bowtie 2. One-way ANOVA with Tukey’s multiple comparison correction, significance p < 0.0001
