ribosome. For the 30S subunit, the
16S rRNA (dark blue) is shown.
This type of sequencing refers to sequencing of the gene for the 16S ribosomal RNA component of a subunit of the prokaryotic ribosome. Previous work has indicated that this gene is highly conserved in bacteria species and thus can be used in phylogenetic studies such as this.
While it may not be surprising that the bacteria that reside on our hands can also be found on our phones, the authors propose that the phones could be used as a non-invasive way to monitor our health. The uses of this screening could include real-time assessment of possible exposure to pathogens that could be carried into and out of a medical facility.
