Our skin is home to millions of
bacteria, fungi and viruses that compose the skin microbiota. The skin is also
colonized by beneficial microorganisms and serve as a physical barrier to
prevent invasion of pathogens. In the below article, they describe amplicon and
shotgun metagenomic DNA sequencing studies that have been used to assess the
taxonomic diversity of microorganisms associated with the skin. They also
discuss the dynamics between species and interactions with the immune system
with a focus on Propionibacterium acnes, Staphylococcus epidermidis and Staphylococcus
aureus. Some of
their results indicated that microorganisms that colonize the skin have
also been shown to affect the healing of chronic wounds prevalent in
populations that are elderly or have diabetes or obesity. The overall question
they however, is what role do the microorganisms have in the skin in
maintaining health or promoting diseases states.
