Examining the skin and workplace microbiome following the return to the University of North Texas Health Science Center after self-isolation

The human skin microbiome contains trillions of microbiomes that colonize the human body. It is unknown how social distancing and an increase in handwashing due to the COVID-19 pandemic affect the bacterial communities that reside on the human hands & fomites. In this research, bacterial swabs from individual's dominant hand, forearm of their dominant hand, and a fomite from the workplace environment were taken, and the resident microflora, i.e., the skin microbiome, was investigated. The DNA from the samples were extracted and amplified by PCR. Samples were then pooled for sequencing of the V4 region of the 16S ribosomal RNA gene using Illumina's MiSeq platform and subsequently analyzed for community composition. The results were compared against each other to determine how an individual and a fomite's microbiome shifted following their return to work. Furthermore, the results were used to determine if individual's microbiome became more similar to each other as they returned to work in the same building.
