Figure 1. Abundance of bacterial and archaeal 16 S rRNA gene copies retrieved from front torsos of 13 people.

Values above bar graphs give percent of archaeal gene copies in the entire prokaryotic microbiome detected. Asterisks indicate an archaeal percentage lower than 0.01. X-axis gives human sample number (Table 1), Y-axis shows log-transformed abundances of 16 S rRNA genes.
